Executive Summary
On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Order Number 2006-0003-
DWO, the Waste Discharge Requirements (WDRs), which requires all federal and state agencies,
municipalities, counties, districts, and other public entities that own or operate a wastewater collection
system greater than one mile in length to develop and implement a system specific Sewer System
Management Plan (SSMP). An SSMP must document how an agency manages its wastewater collection
system. Each agency must present the Development Plan and Schedule to its governing body at a public
meeting prior to certifying the document. The City of Anaheim (City) was required to certify its first SSMP
on or before May 2, 2009 and must recertify the SSMP every five (5) years.
This SSMP, prepared by the City in compliance with the requirements of the WDRs, documents the City's
system specific plans and programs to operate, maintain, and manage its wastewater collection system.
Goals of the SSMP include:
• Minimizing the frequency and impact of sanitary sewer overflows (SSOs);
• Effectively and efficiently mitigating the impacts of SSOs should they occur;
• Providing adequate sewer capacity to convey peak flows;
• Maintaining and improving the condition of the collection system infrastructure to provide
continual reliable service; and
• Engaging and educating the public regarding programs and issues related to the wastewater
collection system.
The Table ES -1 includes a summary of the mandatory components required by the WDRs and included in
the City's SSMP.

Chapter 1
Introduction
This Sewer System Management Plan (SSMP) has been prepared in compliance with the requirements of
the State Water Resources Control Board (SWRCB), Order 2006-0003, Statewide General Waste Discharge
Requirements (WDRs) for Sanitary Sewer Systems. The goal of the WDRs is to provide a consistent
statewide approach for reducing Sanitary Sewer Overflows (SSO). This chapter includes a brief overview
of the City of Anaheim's (City's) service area and sanitary sewer system, a summary of the regulations that
serve as the impetus for the development of this SSMP, and the purpose and organization of this SSMP.
1.1 Service Area and Sewer System
The City provides sewer service throughout the City and to a limited area outside the City limits. The areas
of service are composed of residential, commercial and industrial land uses. As illustrated in Figure 1-1, in
addition to the City of Anaheim, the City's service area includes portions of Fullerton, Garden Grove,
Cypress, and unincorporated areas of Orange County.
The City's wastewater collection system consists of approximately 570 miles of gravity sewer, 11,000
manholes and 124 siphons. The wastewater generated in the City is collected by the City's wastewater
collection system and conveyed to the Orange County Sanitation District's (OCSD) trunk lines for ultimate
treatment and disposal.
1.2 Waste Discharge Requirements
On May 2, 2006, the SWRCB adopted Order 2006-0003, the Statewide General Waste Discharge
Requirements for Sanitary Sewer Systems, which requires all federal and state agencies, municipalities,
counties, districts, and other public entities that own or operate a sanitary sewer system greater than one
mile in length to comply with the elements of the WDRs. The WDRs serve to provide a unified statewide
approach for reporting and tracking SSOs, establishing consistent and uniform requirements for SSMP
development and implementation, establishing consistency in reporting, and facilitating consistent
enforcement for violations.
On June 27, 2006, the Executive Director of the SWRCB executed a memorandum of agreement with the
California Water Environment Association (CWEA), outlining a strategy and time schedule for CWEA to
provide training on the (1) adoption of the program, (2) SSO database electronic reporting, and (3) SSMP
development. This agreement also extended the completion dates for most tasks by six (6) months from
the dates shown in the adopted WDRs.
The WDRs include directives for owners and operators of sanitary sewer systems to demonstrate
adequate and efficient management, operation, and maintenance of the sanitary sewer system.
Generally, the WDRs require that:

Introduction
a. In the event of an SSO, all feasible steps are taken to control the released volume and
prevent untreated wastewater from entering storm drains, creeks, etc.
b. If an SSO occurs, it must be reported to the SWRCB using California Integrated Water
Quality System (CIWQS), the online reporting system developed by the SWRCB. The City
completed its enrollment into the program and the demographic questionnaire, and
electronic reporting commenced in January 2007.
C. An SSMP with all mandatory elements be developed and approved by the governing body
that owns or is responsible for the operation of the sanitary sewer system. The SSMP must
include provisions to provide proper and efficient management, operation, and
maintenance of the sanitary sewer system.
This SSMP includes the various plans and programs that comprise a comprehensive SSMP. The completion
dates for each mandatory element is determined according to the size of population served by the federal
and state agencies, municipalities, counties, districts, and other public entities that own or operate a
sanitary sewer system. Based on an estimated population of approximately 350,000 customers, the City
must comply with the schedule provided for agencies that serve a population greater than 100,000.
1.3 Purpose
The City recognizes the importance of preventing sewage spills for the mutual protection of our surface
waters and the overall environment to safeguard public health and safety. Therefore, in a proactive
approach to achieve WDR compliance, the City has prepared this comprehensive SSMP. This SSMP is
designed to ensure continuous improvement of system performance, response, monitoring, data
recording, and documentation for future system assessments. The City considers the completeness and
practicality of the SSMP a critical component for its long range plans to comply with all applicable regional,
State, and Federal requirements under the CWA, the Santa Ana Regional Water Quality Control Board
(SARWQCB) and the WDRs.
This SSMP provides a summary of the action plan implemented by the City to comply with the sanitary
sewer system requirements imposed by the WDRs and other governing agencies. As well, it includes the
specific details of the activities and procedures that personnel follow to implement the various programs
encompassed in its overall efforts to efficiently manage, operate, and maintain its sanitary sewer system
and facilitate the reduction and potential elimination of SSOs.
1.4 SSMP Elements and Organization
This SSMP includes detailed information demonstrating the City's efforts to comply with each of the
mandatory and applicable elements required for its SSMP. The organization of this document is consistent
with the SWRCB guidelines and includes the following eleven (11) mandatory WDR elements:

Goals and Objectives
The following sections include a summary of the City's goals that reflect its commitment to continue its
effort towards ensuring the effective and efficient management, operation and maintenance of the
sanitary sewer system.
2.1 Regulatory Requirements for Goals Element
Establishing goals to properly manage, operate, and maintain all parts of its sanitary sewer system allows
the City to achieve its ultimate goal of reducing and preventing SSOs and to properly mitigate any SSO
that may occur. To achieve the goals established by the City, it becomes imperative for City staff to
consistently maintain quality working procedures and continue efforts towards identifying and
implementing improvements in managing the sanitary sewer system.
The WDRs require that the City, at a minimum, develop goals that incorporate and achieve the following:
• Proper management, operation, and maintenance of all parts of the sanitary sewer system;
• Provide adequate capacity to convey peak flows;
• Minimize the frequency and volume of SSOs;
• Mitigate the impacts of SSOs if they occur;
• Inform and educate the public on programs, projects, and issues related to the sanitary sewer
system; and
• Proper implementation of regulatory notification and reporting requirements.
2.2 Goals for City System Maintenance and Management
The City has establish several internal core objectives to allow City staff to focus on complying with the
WDRs, and develop strategies and procedures to achieve successful overall management and
maintenance of the sanitary sewer system. Goals promote unified efforts towards implementing
improvements as they affect the operations, maintenance, and management of the sanitary sewer
system. They may also reflect performance, safety, levels of service, resource use, and other criteria.
The City's ultimate goals include operating and maintaining all portions of the City's sanitary sewer system
to minimize the potential for SSOs and to quickly and effectively mitigate the impacts associated with an
SSO if it were to occur so as to protect life, environment, and property while adhering to regulatory
requirements. To achieve these goals, the City's SSMP includes methods for ensuring that adequate
capacity to convey the peak wastewater flows is provided and that comprehensive procedures are
established to meet all applicable regulatory notification and reporting requirements.
The City's Department of Public Works is responsible for ensuring the proper operation and maintenance
of the wastewater collection system. Its mission statement is:
We are a caring team serving with pride, we plan, we build and preserve our Anaheim community for
today and future generations.

City Organization and Communication
An organizational chart for the City's Department of Public Works serves to identify the administrative,
maintenance, and management positions responsible for implementing, managing, and updating the
overall measures included in this SSMP. This chapter identifies the City's staff that is responsible for
implementing the plans and progress included in the SSMP, responding to SSO events, and meeting the
SSO reporting requirements.
The communication plan that accompanies the organizational chart serves to define the role of each
position to ensure that all elements of this SSMP are addressed on a regular basis and that all appropriate
staff is properly informed. A specific response and notification plan to document the sanitary sewer
overflow emergency response and reporting procedures was developed and is included in the City of
Anaheim Sanitary Sewer Overflow Emergency Response Plan (SSOERP) included in Appendix D. The
response procedure identifies the staff positions responsible for managing the SSO response, investigating
the SSO cause, and reporting the SSO to the appropriate parties. The SSOERP also includes a consolidated
list of contact information of key personnel with regard to SSOs. The sequence of communication for
reporting SSOs, and the appropriate agencies to be notified, is also included.
3.1 Regulatory Requirements for the Organization and Communication Element
It is required that the City's SSMP clearly identify the staff responsible for implementing measures
outlined in this SSMP. The WDRs require that the City identify the following:
a) The name of the responsible or authorized representative;
b) The names and telephone numbers for management, administrative, and maintenance positions
responsible for implementing specific measures of the SSMP program. The SSMP must identify
lines of authority through an organization chart or similar document with a narrative explanation;
and
c) The chain of communication for reporting SSOs, from receipt of a complaint or other information,
including the persons responsible for reporting SSOs to the State and Regional Water Board and
other agencies if applicable (such as County Health Officer, County Environmental Health Agency,
and/or State Office of Emergency Services).
3.2 Discussion on Organizational Structure

City Organization and Communication
All nineteen (19) positions are currently staffed. In addition to the staff within the Public Works Operations
Division, staff from the other divisions provide some staff time in support of the Public Works Operations
Division. The Planning Department, Engineering Division, Construction Services, and Fleet and Facility
Services will provide coordination and technical support staff that also provide assistance in the
implementation of various elements of the SSMP.
The organizational chart presented in Figure 3-2 shows the departments, divisions, sections, and positions
identified within the City's current organization that are responsible for concurrently implementing and
managing various components of plans and procedures required to satisfy the elements of the SSMP.
Highlighted on the organizational chart are the current fiscal year's budgeted positions in the Public Works
Operations Division, the section that is primarily responsible for operating and maintaining the sanitary
sewer system. The boxes shown in dashed lines identify departments and divisions that provide some
day-to-day support of the sanitary sewer system, but these divisions also have other, unrelated duties.
Examples of functions provided by these divisions include engineering and system mapping assistance,
permit oversight and possible heavy construction support.
The organizational chart will be revised to reflect the updated key staff positions, responsibilities between
the divisions that support the Public Works Operations activities, changes in the restructuring of chains -
of -command made to better align responsibilities and the ability of staff to comply with the WDRs, and to
include changes and additions to positions for activities needed to successfully implement the SSMP.
Although compilation and maintenance of up-to-date contact lists is required for compliance with the
WDRs, it has been included separately in the SSOERP to facilitate routine updates.

3.3 City Communication Structure for Collection System Issues
Communication of activities is important in order to keep managerial staff informed of successes and
potential problems. Additionally, implementation of the various elements of the SSMP will require
constant coordination between the various sections identified in the organizational chart. Therefore,
clearly identifying the specific positions and staff as well as establishing communication protocols is
necessary to ensure the appropriate personnel are properly informed to respond to sanitary sewer system
related issues in the most effective and efficient manner.
3.3.1 SSMP Communication Structure
Continual communication among the Public Works Operations and Engineering Divisions as well as along
the levels of hierarchy facilitates and supports activities that allow the Public Works Operations Division
to inform the appropriate staff about the operation and management of the collection system.
Generally the communication plan will follow the chain of command identified in the organizational chart.
Specific levels of authority will be required to facilitate implementation and enforcement of the plans and
procedures developed for the SSMP. As the various plans and procedures are implemented, an
assessment as to the effectiveness of the plans will best be determined by the labor force that executes
and evaluates the immediate impacts of the plans and procedures. Efficient and timely responses will be
essential to ensure that the adopted plans and procedures are effective for the management and
operation of the wastewater system. Figure 3-3 shows the communication protocol that the City should
follow for the SSMP. Figure 3-3 also provides a summary of general responsibilities among the staff as it
affects the management, operation, and maintenance of the City's sanitary sewer system. The
responsibilities listed are to illustrate the overall importance of continual communication among the
organization regarding wastewater related issues.
3.3.2 SSO Response and Communication Structure

City Organization and Communication
An SSO is reported to either the Public Works Department, the Utility Department's Customer Service
Division, online via Anaheim Anytime, or the City's after-hours answering service. The call is routed
directly to the Public Works Operations Superintendent, Operations Supervisor, and Crew Supervisor
during normal business hours while during non -business hours, weekends, and designated City holidays,
calls will be routed directly to the City's Utilities Department, the Fire Department, or Police Department
dispatch centers as needed. The City's Utilities Department, Fire Department and/or Police Department
dispatchers will notify the Public Works On -Call Duty Manager via an assigned cell phone.
The staff member receiving the notification is considered the First Responder and has primary
responsibility for coordinating and managing all emergency activities to properly respond to the
occurrence. The First Responder must immediately go to the reported SSO location to assess the cause
and extent of the SSO, recruit necessary assistance from appropriate personnel and/or outside services,
determine and direct immediate remedial action, initiate notification of mandatory and advisory agencies,
coordinate sample collection and laboratory sample processing, if required, and complete the Sanitary
Sewer Overflow Field Report. The size and conditions of the SSO will determine which regulatory agencies
will be notified. Notifications to the following agencies will be performed as required:
• Orange County Sheriff's Department (as necessary)
• Governor's Office of Emergency Services
• Santa Ana Regional Water Quality Control Board
• Orange County Health Care Agency (as necessary)
• Orange County Public Works (as necessary)
• City of Anaheim Risk Management Division (when a public SSO enters a home or business)
A response and notification procedure is documented in the SSOERP, included in Appendix D. Figure 2-1
of the SSOERP illustrates the response procedures for the potential scenarios (public or private SSOs) and
clearly delineates responsibilities for First Responders and ultimate sewer maintenance crew and/or
contractor assignments. Table 2-2 of the SSOERP describes the SSO notification requirements, procedures,
timeline, and the regulatory agencies that are to be notified.
3.4 Summary and Continuing Efforts
When the City updates its plans and procedures, and/or revises the SSMP, the SSMP should be updated
as necessary to include the specific responsibilities associated with each position. To maintain compliance
with the WDRs, the City organizational chart must include the administrative, maintenance, and
management positions responsible for implementing, managing, and updating the overall measures
contained in this SSMP. Key contact lists are included in the appendices and attachments to facilitate
updates.

Chapter 4
Legal Authority
To prevent SSOs and meet state and federal requirements, each governing agency must ensure that its
existing codes, ordinances, policies and procedures include the necessary requirements to implement and
fulfill the specific needs of the agency, and to protect the health and safety of people, property, and
environment. This chapter of the SSMP includes a discussion of the City's current legal authority for the
collection and conveyance of wastewater.
4.1 Regulatory Requirements for Legal Authority Provisions
The WDRs require that the City show, through ordinances, service agreements, or other legally binding
procedures, that the City possesses the legal authority to:
a) Prevent illicit discharges into its sanitary sewer system including, but not limited to, inflow
and infiltration, storm water, chemical dumping, unauthorized debris, and cut roots, etc.;
b) Require that sewers and connections be properly designed and constructed;
c) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or
maintained by the City;
d) Limit the discharge of fats, oils, grease, and other debris that may cause blockages; and
e) Enforce any violation of its sewer ordinances.
4.2 Background for Legal Authority
The California Water Code of the California Code of Regulations, the Federal Clean Water Act of the United
States Code, and the California Waste Discharge Requirements grant the City the authority to establish
codes, agreements, policies, and procedures for the construction, operation, and maintenance of a
wastewater collection system, and the ability to enforce the necessary requirements. Below is a discussion
of the relevant sections granting this authority.
California Water Code Section 13271, California Code of Regulations: Section 13271 of the California
Water Code, Title 23 of the California Code of Regulations, prohibits the discharge of sewage and
hazardous material into the waters of the State and requires the proper notification of authorized
agencies in the event of an SSO. Entities which do not properly follow the requirements of this section
may be found guilty of a misdemeanor and punished by fine, imprisonment, or both.
Clean Water Act, Section 1251 of Chapter 33 of the United States Code: In 1972, the federal Congress
enacted the Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA). The
CWA prohibits the discharge of pollutants, including sewage, into public waters of the United States. The
federal government has the authority to enforce compliance with the CWA via specific permits, such as
National Pollutant Discharge Elimination System (NPDES) permits, as well as court action such as
administrative orders and consent decrees.

City of Anaheim
Sewer System Management Plan
April 2019
Legal Authority
Code of Federal Regulations, Title 40, Protection of the Environment: The Environmental Protection
Agency (EPA), in its general pretreatment regulations (40 CFR Part 403) prohibits any user from
discharging solid or viscous pollutants, such as fats, oils, and grease (FOG) wastes, in amounts which will
cause obstructions (blockages) to the flow in the wastewater system and interfere with the operation of
the wastewater system.
California Waste Discharge Requirements: On May 2, 2006, the SWRCB adopted the Statewide General
Waste Discharge Requirements for Sanitary Sewer Systems, Order No. 2006-0003. The WDRs are
applicable to all federal and state agencies, municipalities, counties, districts, and other public entities
that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey
untreated or partially treated wastewater to publicly owned treatment facilities in the state of California.
Specifically, the WDRs require all affected agencies, municipalities, counties, districts, and other public
entities to take a proactive approach to ensure a system -wide operation, maintenance, and management
plan is established to effectively reduce the potential, quantity, and frequency of SSOs that may occur and
impact surface or ground waters, threaten public health, adversely affect aquatic life, and impair the
recreational use and aesthetic enjoyment of surface waters.
4.3 Summary and Evaluation of the City's Existing Legal Authority
The City's legal authority and powers pertaining to the City's wastewater collection system originate from
the powers granted by the State and Federal governments. Requiring compliance with its existing codes,
regulations, ordinances, and permitting procedures allows the City to require and enforce various
measures for ensuring the proper and efficient operation, management, and maintenance of the City's
wastewater collection system. These mechanisms include, but are not limited to, limiting the types of
substances allowed to be discharged into the City's wastewater collection system, establishing
requirements for the proper design, construction and connections to the City's collection system, ensuring
access to City sewer pipelines for inspecting, monitoring and enforcing activities, limiting the discharge of
fats, oils, grease, and other types of debris that cause blockages, and enforcing violations of its sewer
related ordinances, codes, and laws.
The City also requires compliance with the City of Anaheim's Sewer Design Manual and Standard Plans
and Details and in compliance with the "Standard Plans for Public Works Construction" (Greenbook),
prepared by the American Public Works Association for the design, construction, and installation of
wastewater facilities. Collectively, the documents serve to facilitate the control of inflow and infiltration
(1/1); require proper design, construction, installation, testing, and inspection of new and rehabilitated
sewers and laterals; control the discharge of FOG; enforce violation of ordinances; and promote and
protect the health, safety, and general welfare of all of the citizens of the City of Anaheim.
The following sections include a summary of the City's existing codes and ordinances as they apply to its
sanitary sewer system.
4-2
City of Anaheim
Sewer System Management Plan

Legal Authority
4.3.1 Prevention of Illicit Discharges
The City is required to prevent discharges of illicit and undesirable substances from entering the
wastewater collection system. Illicit discharges include, but are not limited to, the release of 1/1, storm
water, chemical dumping, unauthorized debris and constituents, and cut roots. Discussed below is the
City's authority to control the discharge of the prohibited substances.
Section 10.08.040, Substances Banned from the Public Sewers, includes a general description of the
various types of substances restricted by the City from being directly or indirectly discharged into the
collection system. The restrictions are applicable to all users of the City's system except as permitted by
other ordinances of the City.
This section of the municipal code also further restricts the substances allowable into the system by
including a description of the effects on the system the City intends to avoid. Generally, the prohibited
items include substances with characteristics that may cause:
• Obstructions to the flow in the sewer system;
• Interference with the operation of the Publicly Owned Treatment Works;
• Damage or create a hazard to City's wastewater collection system structures;
• Damage or create a hazard to the City's wastewater collection system equipment;
• A public nuisance or create a hazard to life; and/or
• Interference with the maintenance of the sewage collection system.
Regulating the type of substances allowable in the City's wastewater collection system serves to protect
and maintain its integrity.
4.3.2 Proper Connections and Construction
The requirements for the design and construction of new, rehabilitated, and replaced sewer system
facilities, including mains, tie-ins, service laterals, cleanouts, manholes, and other system appurtenances,
are necessary to ensure the proper operation of the sewer system.
Section 10.08.050, Building Sewer Connections, of the City's municipal code references the Uniform
Plumbing Code and the City's Standard Details for the general requirements pertaining to the design,
construction, inspection and plumbing permits and costs of sewer connections. Collectively, the City's
Sewer Design Manual and Standard Details provide design and construction information for sewer
facilities.

Legal Authority
4.3.3 Accessibility for Maintenance, Inspection, and Repair
Section 10.08.030, Powers and Authority of the Engineer and Inspector, provides the City the authority to
perform inspections of all properties, structure or premises that are served by any public or private sewer,
for the purpose of examining and inspecting the construction or condition of the sewer. Additionally, this
code allows the City Engineer and/or Inspector to inspect as often as deemed necessary every sewage
pumping plant, private sewage disposal system, house connection sewer, dilution basin, neutralization
basin, back -water trap or valve, grease interceptor or grease trap, or other similar appurtenances for the
purpose of ascertaining whether such facilities are maintained and operated in accordance with the
provisions of the chapter.
Although this section provides City staff the authority to access wastewater related facilities, it does not
allow City staff to access the facilities for maintenance purposes or to perform these functions on systems
that discharge domestic wastewater. In the event a site inspection reveals improper maintenance and\or
cleaning and there is imminent danger to the City's sewer facilities or the public, the City should have the
authority to access the site and related facilities to perform the necessary maintenance and cleaning in
an effort to prevent exposing the public to a health risk or hazard and compromising the operation of the
City's wastewater collection system. Additionally, the City should have access to the site for maintenance
and cleaning purposes in the event an emergency occurs that requires the immediate cleaning of the
sewer facilities discharging into the City's wastewater system.
4.3.4 Limit Fats, Oils, and Grease Discharge
Municipal Code 10.08.100, Discharges of Fats, Oils and Grease from Food Service Establishments, serves
to ensure the City's compliance with federal, state, and regulatory agency laws, regulations and standards
relating to FOG discharges to sewer facilities. It also specifies the City's FOG discharge requirements to
enhance the beneficial public use of the City's sewer facilities and prevent blockages of sewer lines
resulting from discharges of FOG and other constituents into the sewer facilities.
The City recently prepared the City of Anaheim Fats, Oils, and Grease Source Control Program (FOG Source
Control Program), that documents and establishes the formal procedures City staff implements to
effectively minimize the direct or indirect discharge of all wastewater or waste containing FOG into the
City's wastewater collection system. Compliance with the program requires Food Service Establishments
(FSEs) and other non-domestic waste and wastewater generating facilities to obtain a permit which sets
forth the specific terms, conditions, and criteria required for compliance with the City's codes and
ordinances, FOG Source Control Program, and policies for each facility requiring connection to the City's
wastewater collection system.
Additionally, this section of the code requires compliance with the provisions applicable to the direct and
indirect discharge of all FOG to sewer facilities. The provisions are included in the FOG Source Control
Program, Fats Oils and Grease Source Control Program Rules and Regulations, kitchen BMPs, FOG pre-
treatment requirements, and monitoring and record keeping requirements.
City of Anaheim
Sewer System Management Plan
4-4 April 2019
Legal Authority
The City's objective is to continue to implement and enforce actions against users of the wastewater
collection system that violate the prohibition of discharging FOG into the wastewater collection system.
The City will continue enforcement actions for noncompliance and it will be possible for other regulatory
agencies to initiate enforcement actions concurrently with City efforts.
4.3.5 Violation Enforcement
The authority for the City to enforce penalties for violations of the City's codes, ordinances and other
adopted policies as they pertain to its wastewater collection system is included in Section 10.08.140,
Penalties, of the municipal code. This section codifies the City's authority to enforce violations of the
codes, ordinances, and applicable policies with respect to the sanitary sewer system.
Section 10.080.140.050 allows the City Engineer to discontinue use, at any premise, of the public
sewerage system that is found to be improperly disposing prohibited substances into the City's
wastewater collection system or that is in violation of specific conditions of the City's municipal code.
Section 10.080.140.060 allows the City to require reimbursement for damages caused to, and any cleaning
required of, any portion of the public sewerage system in the event it is determined that there is a
violation of the provisions included in Section 10.08 of the municipal code and prohibited substances have
been discharged into any public sewer, sewer pipe, manhole, septic tank connected with the public
sewerage system, or municipal industrial waste pipeline within the City.
Section 1.01.370 describes the general penalties for violating sections of the code and for continuing
violations. Individuals convicted of a violation of the City code that is not specifically declared to be an
infraction shall be considered guilty of a misdemeanor, and punished with a fine of not more than
$1,000.00, imprisonment in the city or county jail for not more than six (6) months or both such fine and
imprisonment.

Chapter 5
Operations and Maintenance Program
This chapter of the SSMP discusses the City's operations, maintenance and other related measures and
activities as they pertain to its sanitary sewer system.
5.1 Regulatory Requirements for Operations and Maintenance Program
The WDRs require that the SSMP contain descriptive measures of the City's Operations and Maintenance
(O&M) Program that are implemented by City staff to facilitate proper and efficient management and
maintenance of the sanitary sewer system and the affected appurtenances. The WDRs require that the
SSMP include a description of each of the following components as they apply to the City's sanitary sewer
system:
a) Maintenance of up-to-date sanitary sewer system map showing all gravity line segments and
manholes, pumping facilities, pressure pipes and valves, and applicable stormwater
conveyance facilities;
b) Routine preventive operation and maintenance activities by staff and contractors, including a
system for scheduling regular maintenance and cleaning of the sanitary sewer system with
more frequent cleaning and maintenance targeted at known problem areas. The Preventive
Maintenance Program should have a system to document scheduled and conducted activities,
such as work orders;
c) Development of a rehabilitation and replacement plan to identify and prioritize system
deficiencies and implant short-term and long-term rehabilitation actions to address each
deficiency. The program should include regular visual and TV inspections of manholes and
sewer pipes, and a system for ranking the condition of sewer pipes and scheduling
rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of
failure or prone to more frequent blockages due to pipe defects or root intrusions. Finally, the
rehabilitation and replacement plan should include a capital improvement plan that
addresses proper management and protection of the infrastructure assets. The plan shall
include a time schedule for implementing the short and long-term plans plus a schedule for
developing the funds needed for the capital improvement plan;
d) Provide training on a regular basis for staff in sanitary sewer system operations and
maintenance, and repair contractors to be appropriately trained; and
e) Development of equipment and replacement part inventories, including identification of
critical replacement parts.
5.2 City's Operations and Maintenance Program
The City prepared a comprehensive document titled City of Anaheim Operations and Maintenance
Program (0&M Program) which includes a summary of the City's current procedures and practices as they
pertain to the 0&M activities related to its sanitary sewer system. The City's O&M Program contains
information pertaining to the following components for compliance with the WDRs:

5.3 Discussion of Regulatory O&M Components
To address the components listed in Section 5.1 and as required by the WDRs, the following subsections
provide a summary of the applicable O&M procedures currently being implemented. The following
paragraphs correlate to the WDR components listed in Section 5.1. The complete 0&M Program is
included in Appendix B.
5.3.1 Sanitary Sewer System Mapping
The locations of the City maintained wastewater system pipes and associated appurtenances were
originally documented based on as -built drawings. These as -built drawings were used to develop a
Geographic Information System (GIS) database of the facilities which facilitates management of 0&M
activities and expedites data management and retrieval for reporting purposes.
Necessary revisions and/or updates to the GIS information are typically identified by the Public Works
Operations crews while performing routine operation and maintenance activities. Discrepancies between
field conditions and GIS are input as "redline comments" into the CMMS or emailed to the GIS Section.
Once updates are completed, there are available to all crews via GIS and the CMMS.
5.3.2 Preventive Maintenance Program
The City's sanitary sewer system, as do other aging utilities serving mature communities, has required
frequent maintenance due to age, extended use, debris accumulation, and tree root intrusion. To
minimize and prevent system obstructions and preserve and extend the useful life of the sanitary sewer
system, the City's Preventive Maintenance Program has primarily included the routine cleaning of its
wastewater pipelines. The City's Preventive Maintenance Program includes scheduled cleaning, root
control and manhole treatment and is further documented in the 0&M Program.

O&M Program
Mechanical Cleanine
The City has four sewer cleaning crews that are responsible for annual cleaning of all sewer lines
measuring up to 12 inches in diameter. Any sewer line greater than 12 inches in diameter is cleaned as
needed. The crews have three combination Vactor trucks and one jetting -only truck to accomplish the
cleaning goals. The City divides its sewer service area into four zones: the east, two central zones, and
west zones. One Vactor truck crew is assigned to each zone and the jetting -only truck crew is assigned to
the central zone in the most congested downtown areas. Because sewer lines in the City's downtown area
are older and primarily 6 inches in diameter, the downtown area is cleaned at a higher freqency. Based
on review of historical cleaning data, the City is currently meeting its goal to clean the entire system once
every 18 months and to clean the downtown area every 12 months..
During cleaning, crews observe and document the level of FOG, root, and debris accumulation observed.
Each Vactor truck has an on -board computer equipped with GIS and I -Water computerized maintenance
management system (CMMS). All cleaning and structural observations for each sewer line segment are
entered into the I -Water CM MS system. At the end of each work day, the truck operators synchronize the
on -board computers with the database located in the City's main office. The Operations Manager and
Operations Crew Supervisor periodically review the crews' cleaning comments to determine if any issues,
such as heavy accumulation or structural concerns, were identified. Significant issues that could result in
an SSO are immediately communicated verbally to the Operations Manager. Routine updates are
provided to the Operations Manager and Deputy Director at Quarterly Report Meetings.
The City also has identified recall locations, which are areas of the sewer system that require cleaning
more than once a year. The City established cleaning frequencies for recall locations based on field
observations during cleaning and CCTV evidence. The cleaning frequencies can vary among 30 and 90
days. Under the direction of the Operations Crew Supervisor, each crew is responsible for cleaning recall
locations within their assigned zones. 100 recall locations are dedicated to sewer siphons, and are not the
result of structural defects or excessive root intrusion or FOG accumulation.
Root Treatment
City staff does not currently perform chemical treatment for root removal, but instead focuses on
enhanced maintenance and structural improvements such as cured -in-place pipe (CIPP) lining.. Pipelines
identified as locations with root intrusion problems are cleaned and evaluated on a regular basis. Most
locations previously identified with root intrusion problems have been lined or replaced to prevent the
intrusion. Target sites are generally located in the older developed areas with large mature trees as well
as locations identified via the CCTV inspection efforts that identify high concentration of roots.
The Sewer Maintenance Section also coordinates with the Street Tree Maintenance Section to address
root intrusion issues. In areas where root intrusion is problematic, the Sewer Maintenance section may
request that a tree be removed, so long as it meets the removal criteria established by the Street Tree

Maintenance Section. Removed trees are replaced with species more appropriate to the location and with
less invasive root systems.
Manhole Treatment Program
To control infestations of insects and to maintain adequate access to the system, the City's wastewater
collection system manholes are systematically treated for the removal of roaches. The roach treatment
program implemented by City staff includes using soap foam to spot treat infestations in manholes.
Additionally, the City has retained an independent contractor that treats approximately 10,000 manholes
with an epoxy impregnated with pesticide every two (2) years.
5.3.3 Sanitary Sewer System Inspection and Condition Assessment Program
Regular and systematic inspection and assessment of sanitary sewer system facilities provides a means to
monitor the condition of the facilities, the effectiveness of the maintenance operations, and provides a
basis for identifying and scheduling capital improvements. As well, the overall assessment can be used to
determine the funding required to repair, rehabilitate, and replace an aging collection system and to
prioritize the allocation of funds and optimize the expenditure and efforts to operate a sewer collection
system.
System Inspection and Assessment
The City employs Closed Circuit Television (CCTV) technology for the inspection of its pipelines for
maintenance purposes. The CCTV inspections are performed subsequent to pipe cleaning and debris
removal and of all new and rehabilitated pipelines to identify potential defects, determine the
effectiveness of the cleaning efforts, and ensure contractor compliance with City design and construction
standards. The City's CCTV truck is equipped with Granite XP - PACP software developed by Cues. Using
the Granite XP software, pictures of all detected defects and potential problems that may require repair
are recorded onto the truck's database and printed.
Generally, condition assessment of the sewer pipelines is performed in the field during the CCN
inspection process by the City field maintenance crews performing the inspections. Defects detected are
recorded on a computer using PACP compliant software. Defect(s) and potential problem(s) are reported
to the Crew Supervisor for review and to identify the necessary repair method. Permanent records of the
detected defects stored on the CCN truck's computer hard drive and periodically uploaded to the City's
central CCN server.
Progress is recorded on a log by the staff and is maintained on the CCN truck for tracking progress and
for reference. A progress report is submitted to the Public Works Operations Crew Supervisor and utilized
for recording, tracking, and reporting purposes. As the necessity to televise a particular location or portion
of the wastewater collection system arises, staff is assigned to accommodate the requirement. The City
generally televises its sewer system from west to east with the goal of inspecting all pipes under 12 -inches
in diameter in approximately seven (7) years.

O&M Program
Repair and Rehabilitation Projects
The City's Public Works Operations Division is responsible for ensuring that immediate "unscheduled"
repairs and/or rehabilitation improvements of various types and pertaining to wastewater facilities are
adequately performed. The repairs and/or rehabilitation work performed the City's repair contractors
may be identified via the CCTV inspections and primarily include point repairs and CIPP lining, but does
not include work requiring the replacement of entire pipe segments between manholes. Repairs that
require resources beyond those available within the Public Works Operations Division or require further
prioritization and planning are coordinated and scheduled with the City's Engineering Division.
CIP Development
Several factors determine the priority of projects identified during the assessment process, although the
condition of the pipe is usually the primary factor. Additional factors may include goals to reduce sanitary
sewer overflows, providing sufficient system capacity, reducing infiltration and inflow in pipes located
below the water table, or reducing maintenance efforts by improving the pipe condition. Other
considerations include coordinating surface and utility improvements with the other agencies that may
be impacted by improvements. Integrating the results of the inspection and assessment efforts, with the
capacity modeling efforts, the City will pursue a proactive and comprehensive long-range planning effort.
5.3.4 Training Program
Prior to performing any work on City facilities, Public Works Operations staff is trained on the existence
and the provisions of the wastewater operations and maintenance policies, procedures, safety policies,
and the equipment used. Training for operation of City equipment includes the completion of a training
competency model in conjunction with "on-the-job" training.Bi-weekly "tailgate" meetings are held to
discuss safety issues and training needs. For bi-weekly meetings, topics are selected and presented by the
Crew Supervisor with input from the operators and higher management. General meetings are conducted
by the Operations Superintendent on topics selected by the supervisors and are typically relevant to
recent activities and/or events and safety issues.
All maintenance crews are trained and certified to implement proper traffic control procedures.
Additional instructional material should include the City's approved SSMP and the SSOERP. This will serve
as a mode of instructing staff on the SSMP, SSOs, and all the required documentation. Training and event
participation must be documented and maintained by the Public Works Operations Division. As necessary
and determined by appropriate managerial staff, training programs may also include supplemental
technical training required to efficiently and safely perform specific job related duties.
Although not currently required, the City encourages its Public Works Operations staff to obtain all four
(4) grade levels included in the Technical Certification Program for Collection System Maintenance
sponsored by California Water Environment Association (CWEA). The City's incentive program reimburses
5-5
City of Anaheim
Sewer System Management Plan
April 2019
O&M Program
its staff for the associated test fees and the contact hours once the successful completion of the test is
confirmed. The City also proactively sends employees to CWEA seminars and other similar trainings as
they become available. As necessary and determined by appropriate managerial staff, training programs
may also include supplemental technical training required to efficiently and safely perform specific job
related duties.
The City also constructed a non-functioning, demonstration 8 -inch PVC sewer line with two manholes in
the Public Works Yard specifically for training purposes. This line is used to train employees on equipment
use in a safe, controlled environment. It can also be used to simulate sanitary sewer overflows and
associated response procedures.
5.3.5 Equipment and Replacement Part Inventories
The Public Works Operations and Maintenance Division maintains an inventory of City vehicles and
replacement parts. The inventory of vehicles and equipment available for performing the daily routine
operations and maintenance of the City's wastewater collection system includes the type and quantity of
the equipment. The City also retains contracts with authorized dealers for replacement parts on specialty
equipment, such as parts for combination vacuum-jetter trucks.
The City's vehicles and sewer system replacement parts are made readily accessible to maintenance staff.
The replacement parts maintained in the Operations Yard are for the specific types of repairs the Public
Works Operations staff performs. As necessary, maintenance staff solicits the utilization of resources,
including equipment and staff from other divisions. For implementation of repairs that extend beyond the
City's internal resource capabilities, the City retains the services of professional contractors.

Fats, Oils, and Grease Control Program
This chapter of the SSMP discusses the City's FOG Control Program including identification of high
frequency maintenance locations and source control.
6.1 Regulatory Requirements for a FOG Control Program
To comply with the WDRs, the City is required to evaluate its service area to determine whether a FOG
Control Program is necessary. If deemed necessary, the City is required to develop and implement a FOG
Control Program to effectively control the quantity of FOG that is discharged into the City's sanitary sewer
system. The FOG Control Program shall include the following as appropriate:
a) An implementation plan and schedule for a public education outreach program that promotes
proper disposal of FOG;
b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system
service area. This may include a list of acceptable disposal facilities and/or additional facilities
needed to adequately dispose of FOG generated within a sanitary sewer system service area;
c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs
and blockages caused by FOG;
d) Requirements to install grease removal devices (such as traps or interceptors), design
standards for the removal devices, maintenance requirements, BMPs requirements, record
keeping and reporting requirements;
e) Authority to inspect grease producing facilities, enforcement authorities, and whether the
Enrollee has sufficient staff to inspect and enforce the FOG ordinance;
f) An identification of sanitary sewer system sections subject to FOG blockages and
establishment of a cleaning maintenance schedule for each section; and
g) Development and implementation of source control measures for all sources of FOG
discharged to the sanitary sewer system for each section identified in (f) above.
6.2 Discussion of FOG Control Program
The City prepared and implemented a FOG Control Program in 2005. The program documents its current
activities and facilitates the maximum beneficial public use for the City's sanitary sewer system while
preventing blockages of the sewer lines and reducing the adverse effects on sewage treatment operations
resulting from discharges of FOG into the system.
The City's FOG Control Program summarizes the components of the processes and procedures intended
to reduce the quantity of FOG discharged into the City's sanitary sewer system to achieve the goal of
minimizing SSOs due to excessive FOG. The key elements of the City's FOG Control Program include:
6-1
City of Anaheim
Sewer System Management Plan
April 2019
FOG Control Program
• FOG Control Ordinances
• Effluent Limitation & Discharge Requirements
• Kitchen Best Management Practices
• FOG Pretreatment
• Notification, Record -Keeping, & Reporting Requirements
• Grease Interceptor Installation and Operation Requirements
• Grease Trap Operation, Inspection, and Maintenance Requirements
• Waste Hauler Requirements
• Plumbing Permits, Inspection, and Enforcement
• Public Education
To address the components required by the WDRs, the following subsections provide a summary of the
applicable FOG control procedures currently being implemented. The complete FOG Control Program is
included in Appendix C.
6.2.1 Public Education Program
A component of the City's FOG Control Program has been on source control with a concentrated effort in
educating FSE staff and on the negative impacts of putting FOG into the wastewater collection system.
During the regularly performed site inspections, City staff provide an educational binder with information
and practical suggestions for reducing the quantity of FOG discharged into the City's wastewater
collection, engaging FSE staff in reducing FOG related SSOs. To date, the City's efforts to educate FSE staff
has been effective in attaining the desired results from the FSEs.
6.2.2 Disposal of FOG
In addition to the FOG Ordinance, the City has adopted Fats, Oils, and Grease Source Control Program
Rules and Regulations to specify appropriate FOG discharge requirements and limitations for FSEs to
prevent blockages of sewer lines resulting from discharges of FOG.
Additionally, the Rules and Regulations include BMPs which are simple and effective practices that an FSE
can implement to prevent and reduce the quantity of FOG discharged into the sanitary sewer system. The
BMPs include specifics for items including, but not limited to, collection, storage and disposal of waste
cooking oil; disposal of FOG waste into trash rather than sinks or floor drains; employee training; signage;
and availability of spill kits.
The effluent limitations and requirement for the pretreatment of wastewater flows generated at FSEs is
also included in the FOG Control Program. General FOG pretreatment requirements are specified in the
ordinance. Specifics are included in the Rules and Regulations. The ordinance includes provisions such
that existing FSEs are not required to install a grease interceptor, unless the FSE adversely impacts or has
6-2
City of Anaheim
Sewer System Management Plan
April 2019
FOG Control Program
the reasonable potential to adversely impact, the sanitary sewer system by causing or contributing to FOG
high maintenance locations, interference, or SSOs.
6.2.3 Legal Authority to Prohibit Discharges
The City's current legal authority to limit and prohibit FOG from entering the City's wastewater collection
system is established through its existing municipal codes, regulations, ordinances, and permitting
procedures. Section 10.08, Domestic and Industrial Waste, of the City's municipal code, includes the City's
requirements and prohibitions pertaining to the use of the City's wastewater collection system.
Specifically, Section 10.08.040, Substances Banned from the Public Sewers, of the City's municipal code,
includes a general description of the various types of substances restricted by the City from being directly
or indirectly discharged into the collection system. The restrictions are applicable to all users of the City's
system. As well, Section 10.08.100 specifically addresses the FOG discharge limitations for FSEs pertaining
to the direct or indirect discharge of FOG to the City's sewer facilities.
FOG Ordinance 5950, which serves to adopt the City's Fats, Oils, and Grease Source Control Regulations,
also specifies appropriate FOG discharge requirements, limitations, and prohibitions for FSEs to prevent
blockages of sewer lines resulting from discharges of FOG. The key elements of the Rules and Regulations
applicable to FSEs include implementation of Kitchen BMPs, installation, operation and maintenance of
an approved type and adequately sized grease control device, and the notification, record keeping and
reports.
6.2.4 Requirements for Installation of Pretreatment Devices
The requirement for the installation of a grease interceptor is a key requirement of the City's municipal
code and FOG Rules and Regulations. Figure 4-1 of the FOG Control Program (See Appendix C) describes
the evaluation process currently utilized to determine whether installation of a grease interceptor is
required.
Sizing and installation requirements for the grease interceptors are determined by the City's Building
Division which reviews and approves the sizing and installation of grease interceptors with input from the
Public Works Engineering / Development Services Division as a part of the building permit process. The
Building Division bases the design and sizing of the grease interceptors on the adopted version of the
California Plumbing Code (CPC).
City staff requires compliance with specific sections of the adopted CPC. Cleaning and removal of
accumulated grease is required by a licensed waste hauler with an approved license from an authorizing
agency. To ensure proper disposal of the collected grease, the FSE is required to maintain copies of hauling
documentation.

FOG Control Program
6.2.5 Facility Inspection
The City focuses its inspection efforts on "Recall Sites," FSEs, and establishments that have historically
discharged FOG to the sewer system. The inspections serve to ensure compliance with the City's municipal
code, FOG Control Program Ordinances and requirements, and the Fats Oils and Grease Source Control
Program Rules and Regulations. Compliance with the City's municipal code requires that reasonable
access to all parts of the FSE be made available when inspection and/or sampling of the wastewater is
required.
As part of an agreement with the City, the Orange County Health Care Agency (OCHCA) inspects FSEs for
FOG compliance at least once a year during routine health inspections. Follow up inspections are
conducted if the OCHCA inspection encounters establishment deficiencies, private SSOs, contribution to
a high frequency maintenance location or other violations. BMP inspections are conducted to evaluate
compliance with the facility's best management practices requirements. Enforcement inspections are
conducted when increased enforcement is deemed necessary or when the establishment's Conditional
Waiver or Variance is revoked.
Since the City's proactive maintenance procedures have been successful in minimizing the number of SSOs
and addressing the high frequency maintenance locations, the City intends to continue its current FOG
Control Program.
6.2.6 Maintenance Schedule for High Frequency Maintenance Locations
The performance and scheduling of preventive, operation and maintenance activities is performed by the
existing staff. The Preventive Maintenance Program includes a cleaning cycle for the areas that have been
identified by City staff as "Recall Sites." The City's Recall Sites include pipe segments with high FOG, root
intrusion, and siphons. The pipe segments within the wastewater system identified as Recall Sites are
routinely cleaned on a 30, 90, and 120 day basis based on field observations, historic conditions, or
operator/ supervisor recommendations.
6.2.7 Development and Implementation of Source Control Measures
Detailed information pertaining to the implementation of the City's FOG Control Program and the source
control measures for all sources of FOG discharged to the sanitary sewer system is included in the FOG
Control Program which is included in Appendix C..

Sanitary Sewer Overflow Emergency Response Plan
This chapter of the SSMP provides a summary of the City's SSOERP. A copy of the City's SSOERP is included
in Appendix D for reference.
7.1 Regulatory Requirements for Overflow Emergency Response Plan
The WDRs require that the City develop and implement an overflow emergency response plan which
identifies measures to protect public health and the environment. At a minimum, the plan must include
the following:
a) Proper notification procedures so that the primary responders and regulatory agencies are
informed of all SSOs in a timely manner in compliance with the MRP;
b) A program to ensure an appropriate response to all overflows;
c) Procedures to ensure prompt notification to appropriate regulatory agencies and other
potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers,
etc.) of all SSOs that potentially affect public health or reach the waters of the State in
accordance with the Monitoring and Reporting Program (MRP). All SSOs shall be reported in
accordance with this MRP, the California Water Code, other State Law, and other applicable
Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the
officials who will receive immediate notification;
d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow
the Emergency Response Plan and are appropriately trained;
e) Procedures to address emergency operations, such as traffic and crowd control and other
necessary response activities; and
f) A program to ensure that all reasonable steps are taken to contain and prevent the discharge
of untreated and partially treated wastewater to waters of the United States and to minimize
or correct any adverse impact on the environment resulting from the SSOs, including such
accelerated or additional monitoring as may be necessary to determine the nature and impact
of the discharge.
g) Flow Monitoring for large SSOs in excess of 50,000 gallons
7.2 Discussion of Overflow Emergency Response Plan
The City prepared the SSOERP that establishes the formal procedures for City staff to contain, correct, and
clean up SSOs. The SSOERP is intended to provide the City with a comprehensive document that includes
components necessaryfor minimizing the effects of SSOs on the environment while protecting the public's
health and safety.
The SSOERP includes a strategy for the Sewer Maintenance Section to mobilize labor, material, tools, and
equipment to contain, mitigate, and clean-up residuals from an SSO and correct or repair any condition

SSOERP
which may cause or contribute to an un -permitted sewage discharge. The document provides the
necessary guidelines for City staff to respond to an SSO event and contains the following elements:
• Introduction and Regulatory Requirements
• Sanitary Sewer Overflow Emergency Response Plan
• Public Advisory of Sewage Contamination Procedures
• SSO Reporting Requirements
• Training Requirements
• SSOERP Updating Requirements
• Various Attachments
To address the components listed in Section 7.1 and as required by the WDRs, the following subsections
provide a summary of the applicable procedures that are currently being evaluated for implementation
and included in the SSOERP. Further detailed descriptions of the policies and procedures as they pertain
to responding to SSOs are included in the SSOERP document included in Appendix D.
7.2.1 SSO Notification Procedures
The SSOERP includes procedures for proper notification of the appropriate staff in a timely manner.
Notifications of possible SSOs are received via telephone calls or online via Anaheim Anytime. All
telephone calls or complaints for actual or possible SSOs are routed directly to the Public Works
Operations Division from either City's Customer Service or the Utilities Department if the notification is
received during non -business hours.
The City has the primary responsibility of notifying the County of Orange when surface waters or ground
surfaces become polluted from uncontrolled wastewater discharges from its facilities. Most of the surface
waters within City boundaries are under the jurisdiction of the County of Orange, and the Orange County
Health Care Agency and / or Public Works typically makes the determination to post notices. The postings
do not necessarily prohibit the use of recreational areas, unless posted otherwise, but provide a warning
of potential public health risks due to sewage contamination.
The posting of notices shall be done as soon as practicable following the initial response to the overflow.
Signs should be posted on either side of the point of entry where sewage entered the body of water or
public facility and the nearest public access point to that body of water or public facility. Examples of signs
are included in Attachment H of the SSOERP.
Should additional notification of sewage contamination be deemed necessary, City staff shall, in
cooperation with the City's Public Information Office (PIO), provide further notices through the use of pre -
scripted notices made available to the printed or electronic news media for immediate publication or
airing, or by other measures, such as door hangers. Examples of pre -scripted notices, which are included
City of Anaheim
Sewer System Management Plan

SSOERP
in Attachment I of the SSOERP, may be modified to accurately reflect the conditions at the time of
publication and/or airing.
7.2.2 SSO Response
The City's SSOERP includes response priorities, safety, and overflow containment, correction, and clean-
up measures for potential or actual SSOs of various types. Specific actions to be performed by the Public
Works Operations Division staff and additional crews for public and private SSOs are outlined and
described. To summarize the SSO response procedures, a flow chart that illustrates the City's emergency
response procedures, including notification and request of additional resources as required in the event
of a large SSO, is included and offers a concise overview of the steps required to quickly respond to an
actual or possible SSO event.
7.2.3 Procedures for Prompt Notification of Regulatory Agencies
The volume, impact, and location of an SSO determine the level of notifications required to comply with
City and regulatory requirements. Included in the SSOERP is Table 2-2 that summarizes the officials and
agencies to be notified and under what conditions they are to be notified of an SSO. Attachment C of the
SSOERP includes a list of the specific names and telephone numbers of the individuals to be notified. The
contact list should be updated as necessary and verified at least annually.
7.2.4 Training of Appropriate Staff and Contractors
Appropriate staff will participate in regularly scheduled training sessions to assist response crews in
awareness of their responsibilities and executing their duties. The training sessions will be organized
based on the latest SSOERP as well as other reference materials. Training will also incorporate hands-on
field demonstrations to insure the preparedness of all response personnel to all anticipated situations.
Training and event participation will be documented and maintained. Currently, Public Works Operations
staff is encouraged to receive training through various vendors. Additionally, the City encourages its staff
to obtain the CWEA sponsored Collection System Maintenance certification. CWEA training and
certification is encouraged at all four (4) grade levels. Additional certification requirements may be
imposed in the future if deemed necessary by the SARWQCB.
7.2.5 Emergency Procedures and Response Activities (i.e. traffic/crowd control and other necessary
response activities)
Guidelines for traffic and crowd control to limit public access to areas potential impacted by unpermitted
discharges of sewage based on the various types of SSOs are also provided. Traffic and crowd control
guidelines are included in Section 2.6 of the SSOERP.

Additional response activities are detailed in Chapter 3 of the SSOERP that may include posting of notices
which shall be done as soon as practicable following the initial response to the overflow.
7.2.6 SSO Prevention and Containment
The City follows an O&M Program to prevent SSOs. The City's Preventative Maintenance Program includes
the routine cleaning and inspection of the wastewater pipelines and specifically the high frequency
maintenance locations.
The SSOERP provides the guidance to facilitate and ensure the proper response to any type of potential
SSO occurrence. The SSOERP includes a strategy for the Public Works Operations staff to mobilize labor,
material, tools, and equipment to contain, mitigate, and clean-up residuals from an SSO and correct or
repair any condition which may cause or contribute to an un -permitted sewage discharge. Appropriate
mitigation measures to contain the SSO and recover spilled sewage to minimize the impact to the public
or environment are included. Additionally, City staff will implement monitoring measures and perform a
thorough assessment of the site for potential future SSOs and to prevent SSOs from re -occurring. The
efforts serve to minimize and correct any adverse impact on the environment that may potentially result
from an SSO.

Design and Performance Provisions
This chapter of the SSMP discusses the City's design and construction standards and serves to fulfill the
Design and Performance Provisions required by the WDRs.
8.1 Regulatory Requirements for Design and Performance Element
The WDRs require that the SSMP address the following:
a) Design and construction standards and specifications for the installation of new sanitary sewer
systems, pump stations, and other appurtenances; and forthe rehabilitation and repair of existing
sanitary sewer systems; and
b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and
other appurtenances and for rehabilitation and repair projects.
8.2 Discussion on Design and Performance Provisions
Municipal Code 10.08.050 codifies the City of Anaheim's current design and performance criteria. The
code references the latest edition of Uniform Plumbing Code (UPC) and the City's Standard Details for the
design, construction, and inspection of wastewater collection facilities. Detailed design criteria are
documented in the City's Sewer Design Manual and Standard Drawings for Construction.
The City's Sewer Design Manual is supplemented with the appropriate provisions of the adopted Standard
Specifications for Public Works Construction (Greenbook), Standard Plans for Public Works Construction
(SPPWC) and the requirements contained in the City's Contract Documents and Standard Specification
Supplement specific to the project, all of which specify detailed design, inspection and installation criteria
for sanitary sewer design and construction. A copy of the City's current Sewer Design Manual and
Standard Details are included in Appendix E and a sample of the City's Contract Documents and Standard
Specification Supplement is included in Appendix F for reference.
To address the components listed in Section 8.1 and as required by the WDRs, the following subsections
provide a summary of the applicable provisions currently being implemented by the City.
8.2.1 Design and Construction Standards and Specifications
Criteria for the design and construction of new, rehabilitated, and replaced sewer system facilities,
including main, tie-ins, service laterals, cleanout, manholes, and other system appurtenances, are
necessary to ensure the proper operation of the wastewater collection system.
All public sewer mains constructed within the City or under contract to the City are constructed according
to the City's Sewer Design Manual and Standard Drawings, and in compliance with the "Standard
City of Anaheim
Sewer System Management Plan
April 2019
Design and Performance Provisions
Specifications for Public Works Construction" (Greenbook), prepared by the American Public Works
Association.
The City's Sewer Design Manual and Standard Drawings include minimum design standards for sewer
mains, sewer manholes, sewer laterals, and general guidelines for performing the hydraulic analysis.
Additionally, the City's Sewer Design Manual references the SPPWC and Greenbook regarding sewer
connection locations, pipe installation and pipe bedding sections.
Design considerations for wastewater facilities that the City considers non-standard, such as pump or lift
stations, force mains, siphons, internal sealing of existing sewers, outfall sewers, energy dissipaters,
regulating devices, and/or flow measurement devices, are not included in the Sewer Design Manual and
Standard Drawings and require prior approval from the City before design can begin.
8.2.2 Inspecting and Testing
Compliance with the City's Sewer Design Manual and Standard Details, the Greenbook, and the SPPWC
requires the contractor performing work on the City's sewer facilities to be responsible for conducting a
CCTV inspection for all new and rehabilitated sanitary sewer systems and other appurtenances.
The Greenbook includes procedures and standards for inspecting and testing the installation of sewer
mains and related appurtenances and for the rehabilitation and repair of existing sanitary sewer systems.
Compliance with the Greenbook specifications requires air tests to be performed in accordance with
Section 306-1.1.4. As well, it includes inspection and testing criteria for various pipe materials and
installation methods. Section 500-1.2.6 requires the Engineer to review pipeline inspection video
submitted by the Contractor to verify the pipeline point repair or replacement when retained for
construction and installation of wastewater pipelines and manholes prior to backfilling.
Municipal Code 10.08.030 provides the City's Engineer and/or Inspector the authority to enter any
property, structure or premises served by any public or private sewer facility for the purpose of examining,
inspecting the construction or condition of the sewer or appurtenances.

Chapter 9
System Evaluation and Capacity Assurance Plan
Identified as an element of the SSMP, the WDRs require each agency to prepare a System Evaluation and
Capacity Assurance Plan. This chapter of the SSMP discusses the City's capacity management measures to
address the current and future capacity requirements of its collection system and the recommended
capacity improvement projects.
9.1 Regulatory Requirements for System Evaluation and Capacity Assurance Plan
The WDRs require that the City prepare and implement a CIP that will provide hydraulic capacity of key
sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design
storm or wet weather event. At a minimum, the plan must include:
a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are
experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation
must provide estimates of peak flows (including flows from SSOs that escape from the system)
associated with conditions similar to those causing overflow events, estimates for the capacity of
key system components, hydraulic deficiencies (including components of the system with limiting
capacity) and the major sources that contribute to the peak flows associated with overflow
events;
b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation
identified in (a) above to establish appropriate design criteria; and
c) Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to
address identified hydraulic deficiencies, including prioritization, alternatives analysis, and
schedules. The CIP may include increases in pipe size, 1/1 reduction programs, increases and
redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation
schedule and shall identify sources of funding.
d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions for the capital
improvement program developed in (a) -(c) above. This schedule shall be reviewed and updated
consistent with the SSMP review and update requirements as described in Section D.14 of the
WDRs.
9.2 Discussion on System Evaluation and Capacity Assurance Plan
In 2005, the City performed an evaluation of its sanitary sewer system and documented the evaluation in
three (3) separate master plans that collectively address the City's complete wastewater collection
system. The Master Plans include The Combined Central Anaheim Area Master Plan of Sanitary Sewers
and The Combined West Anaheim Area Master Plan of Sanitary Sewers, both prepared by CH2MHill, and
The East Anaheim Area Master Plan of Sanitary Sewers prepared by PSOMAS. The Combined Central
Anaheim Area Master Plan was updated in 2017 by PSOMAS as the Central Anaheim Master Plan of
Sanitary Sewers and the West Anaheim Area Master Plan is currently being updated.

System Evaluation and Capacity Assurance Plan
The following provides a brief description of the areas evaluated in each currently completed Master Plan.
Central Anaheim Master Plan of Sanitary Sewers
The Master Plan was completed in December 2017. The Central Anaheim Master Plan includes the
evaluation of the area located east of Euclid Street and west of the Santa Ana River. The study area consists
of residential, commercial, and industrial land uses, as well as limited portions of the cities of Fullerton
and Garden Grove. The areas encompass approximately 10,627 gross acres (16.6 square miles). This study
was modeled by combining a number of existing separate sewer models representing the various basins
or models of the study area generated by the Combined Central Anaheim Master Plan of Sanitary Sewers
dated September 2006. The following tasks were completed:
The report was used as a basis to create new models for the City's Central Anaheim area. The data used
in creating the models was updated and incorporated into the models to more accurately reflect existing
conditions.
Combined West Area Master Plan
The Master Plan was updated in March 2005. The Combined West Area Master Plan includes the
evaluation of the area located west of Euclid Street. The area, which includes residential, commercial and
industrial land uses, encompasses portions of Fullerton, Garden Grove, Cypress, and unincorporated areas
of Orange County with an approximate total area of 7,450 gross acres (11.65 square miles).
The Master Plan incorporates four (4) studies previously completed and for which sewer system needs
were identified to address existing and future peak dry weather flows (PDWF). The studies incorporated
include the following:
• Anaheim Plaza and Remaining Central City Areas (AP/RCCA), December 1993
• South Brookhurst Corridor Area and The Remaining Anaheim Plaza Area 1 (SBCA/RAPAl),
March 1995
• North Central Area (NCA), November 1993
• Remaining Central City Area 1(RCCA1), July 1995 (areas west of Euclid Street)
The reports were used as a basis to create new models for the City's West Anaheim area. The data used
in creating the models was updated and incorporated into the models to more accurately reflect existing
conditions.
Combined East Area Master Plan
The Master Plan was completed in December 2005. The objectives of this Master Plan was to evaluate the
sewer system within the eastern portion of the City of Anaheim, generally located east of the Orange

Freeway (SR -57) and Riverside Freeway (SR -91) and identify sewer system needs for existing and build-
out peak dry weather flows (PDWF). The area, which includes residential, commercial and industrial land
uses, encompasses approximate total area of 12,658 gross acres (20 square miles). The study and
additional areas incorporated in this Master Plan include the following:
• Northeast Industrial Area Sewer Deficiency Study (NIASDS), May 1998
• The remaining area located in the East Area
• Mountain Park East and Mountain Park West (separated by SR -241)
Each Master Plan presented an assessment of the hydraulic capacity of the major sewer pipelines located
in the each study area at the time the study was completed. The improvement projects identified were
considered to be required to correct system deficiencies under existing and build -out peak dry weather
flow (PDWF) conditions. Additionally, facilities necessary to provide sewer service to undeveloped areas
based on the designated land use, accommodate the anticipated increase in flows, and ensure sufficient
capacity in the existing sanitary sewer system was identified. Updates to the Master Plans are currently
being conducted based on the latest U.S. Census data and existing conditions. The Master Plans are
scheduled to be completed by the end of 2019.
The following subsections provide a brief summary of the modeled systems, flow estimates, and
evaluation criteria used for the City's sewer system capacity evaluation to address the components listed
in Section 9.1 and as required by the WDRs.
9.2.1 Evaluation
The capacity assessment completed as part of each Master Plan was based on the results of the hydraulic
modeling performed forthe collection system in each study area under current and future estimated peak
dry weather design flows. The hydraulic capacity of major City facilities was determined based on the
quantity of wastewater flows generated and expected to be generated within each of the specific study
areas. The estimated flows were determined based on the developed land use, planned development and
wastewater generation factors for dry weather conditions. The system evaluation was performed to
identify improvements necessary to adequately convey existing wastewater discharges and support
future development flows through build -out conditions. The Master Plans adequately address the dry
weather capacity issues forthe system limits at the time. Additionally, the Master Plans include a summary
of improvement projects and planned sewer facilities to accommodate planned growth, improve
hydraulic capacity, and service previously undeveloped areas. Since the implementation of the Master
Plans, all necessary improvement projects have been completed, and areas in need of improved capacity
that were not addressed were reevaluated to determine the need for capacity enhancement. If needed,
these locations will be added to the revised Master Plans in 2019.
To date, the City has not experienced any SSOs due to hydraulic deficiencies in the sewer system. As the
City implements the identified projects, this will aid in maintaining this record. Additionally, updating the
hydraulic model to include significant system improvements and additions as they occur will help identify
potential capacity problems in the wastewater collection system.

9.2.2 Design Criteria
The City established hydraulic design criteria used in updating each area Master Plan. The following
paragraphs summarize the process and the results.
Hydraulic Model Development
The hydraulic model for each study area was developed based upon the City's prior studies and/or master
planning efforts and available data. The models focused on the City's main sewer trunk lines and tributary
sewer pipes that were 8 -inches in diameter and larger. This is typical within the industry for hydraulic
modeling as these facilities convey the highest flows and are generally more likely to experience future
increases in flow from new development. The City's trunk sewers serve to collect and ultimately convey
the wastewater flows to the Orange County Sanitation District's trunk sewers.
The models for each study area were originally developed using InterFlow. InterFlow is a static hydraulic
computer model developed and provided to the City by CH2M Hill. For each study area, the existing
models were converted to Hydra. Hydra is a hydraulic analysis computer model developed by Pizer that
simulates flow conditions, such as wastewater flow depth, flow rate, and velocity, within pipes and
manholes in the City's wastewater collection system. The model provides a representation of hydraulic
flow conditions over an extended period of time whereas the calculations generated by the steady state
model represents an instant in time in the sewer's capacity and is typically considered conservative for
smaller collection mains.
The following provides a brief summary of the method used for developing the models for each study
area.
Combined West Area Master Plan
The model developed for the Combined West Area Master Plan was based on the models prepared as
part of the previous sewer studies. The models developed with the previous studies used InterFlow.
InterFlow is a static hydraulic computer model developed and provided to the City by CH2M HILL. For the
Combined West Area Master Plan, the existing models were converted to Hydra. Converting to the
dynamic model, Hydra, allowed for the analysis of the pipelines at varying flows over an extended period
of time to determine the City's long-term capacity needs for the next 30 years as indicated in the City's
2004 General Plan. New pipelines constructed since the completion of previous studies were included in
the Hydra models. Additionally, the areas not previously modeled, were created directly in Hydra.
The sewer basin boundaries were delineated in AutoCAD and the land use types within each basin were
identified using existing land use maps. The distribution of land uses was matched to the actual net
acreage for each land use type and the areas were calculated for wastewater producing land uses within

each sewer basin. Density factors for residential land uses were included in the models. Unit flow factors
were used for nonresidential land uses.
Central Anaheim Master Plan of Sanitary Sewers Master Plan
The sewer modeling was completed using the computer modeling software, InfoSewer. InfoSewer
operates within ArcGIS and provides direct GIS integration. Forthis master plan update, the existing sewer
models were converted from Hydra software used in the previous master plan to the InfoSewer software.
In addition, new pipeline improvements constructed after completion of the previous Master Plan in 2006
were included in the InfoSewer model.
Combined East Area Master Plan
The sewer modeling was completed using InterFlow as part of the previous sewer master plan studies.
Converting to the dynamic model, Hydra, allowed for the analysis of the pipelines at varying flows over
an extended period of time to determine the City's long-term capacity needs for the next 30 years as
indicated in the City's 2004 General Plan. Also, new pipelines constructed since the completion of previous
studies were included in the Hydra models. For the areas not previously modeled, the models were
created directly in Hydra.
The sewer basin boundaries were delineated in ArcGIS and the land use types within each basin were
identified. The distribution of land uses was matched to the actual dwelling units or net acreage for each
land use type. Density factors for residential land uses were utilized in the models. Unit flow factors were
used for nonresidential land uses.
Estimated Wastewater Generation Rates
Estimates for wastewater generation rates are typically prepared using population and/or land use data.
As part of consolidating the studies previously prepared and updating each Master Plan, population
growth was projected and residential and non-residential flow factors were reviewed and evaluated.
Population data was obtained from the City's Planning Department and reflected state census data that
was used to estimate the projected population growth for each study area. Based on the projected
population growth, land use data obtained from the City's General Plan prepared in 2004, a review of the
factors used in the previous sewer studies, and model calibration based on flow monitoring data, the data
was collectively used to determine the density and unit flow factors for each study area. As well, unit flow
factors were compared to unit flow factors provided by Orange County Sanitation District. The following
provides a summary of the methodology used in each study area to develop the wastewater generations
rates used to update the Master Plan for each study area.

Residential and Non -Residential Flow Factors
The density factors and the unit flow factors used for existing and build -out land use conditions in previous
studies were reviewed and evaluated. Additionally, flow monitoring was conducted at twenty-five (25)
sites within the study area. Table 2.4 in the Master Plan includes a summary of the thirteen (25) sites
selected from which data was obtained and used for use in the Master Plan. The flow monitoring data
was used to calibrate the computer model to determine existing residential unit flow factors for the areas
monitored. Based on the review and evaluation, the average residential and non-residential flow factors
are shown on Table 2.2 of the Master Plan.
The average dwelling units per acre for existing residential land use was determined by calculating the
average density of various land uses from several representative basins to reflect the localized existing
land use condition. The average number of persons per dwelling unit was obtained from the City's
Planning Department. For build -out conditions, the number of dwelling units per acre was taken from the
City's General Plan and the average number of persons per dwelling unit was obtained from the City's
Planning Department. When compared to previous studies, the density factors determined were similar.
Unit flow factors for non-residential land uses were obtained from the previous City of Anaheim deficiency
studies and OCSD. Based on the review and evaluation of the unit flow factors, it was determined that
flow factors used in previous sewer studies were higher than the flow factors provided by OCSD. As the
OCSD flow factors were considered to be more representative of the existing conditions, they were
incorporated into the model. .
Combined West Area Master Plan
Residential
The density factors and the unit flow factors used for existing and build -out land use conditions in previous
studies were reviewed and evaluated. Additionally, flow monitoring was conducted at sixteen (16) sites
within the study area. Table 5 in the Master Plan includes a summary of the sixteen (16) sites from which
data was obtained and used in the Master Plan. The flow monitoring data was used to calibrate the
computer model to determine existing residential unit flow factors for the areas monitored. Based upon
the review of previously used density and unit flow factors and flow monitoring data, the recommended
residential unit flow factor used to develop the model was 100 gpcd.
The average dwelling units per acre for existing residential land use was determined by calculating the
average density of various land uses from several representative basins to reflect the localized existing
land use condition. The average number of persons per dwelling unit was obtained from the City's
Planning Department. For build -out conditions, the number of dwelling units per acre was taken from the

Non -Residential
Unit flow factors for non-residential land uses were obtained from the previous City of Anaheim deficiency
studies and OCSD. Based on the review and evaluation of the unit flow factors, it was determined that
flow factors used in previous sewer studies were higher than the flow factors provided by OCSD. As the
OCSD flow factors were considered to be more representative of the existing conditions, they were
incorporated into the model. For build -out conditions, 100 percent of the non-residential land use acreage
within the study area was assumed to be contributing to the flows.
Table 3 and Table 4 of The Combined West Area Master Plan include a summary of the Residential Density
Factors and Non -Residential Unit Flow Factors, respectively, used for developing the model for the study
area.

Residential
The density factors and the unit flow factors used for existing and build -out land use conditions in previous
studies were reviewed. Additionally, flow monitoring was conducted at fifteen (15) sites within the study
area. Table 6 in the Master Plan includes a summary of the fifteen (15) sites from which data was obtained
and used in the Master Plan. The flow monitoring data was used to calibrate the computer model to
determine existing residential unit flow factors for the areas monitored. Based upon the review, the
recommended residential unit flow factors used were 80 gpcd and 100 gpcd for existing and build -out
flow conditions, respectively. These factors are generally within the range of typical values for cities and
agencies in Southern California.
Table 2 and Table 3 of The Combined East Area Master Plan include a summary of the Existing Residential
Density and Unit Flow Factors and the Build -Out Residential Density and Unit Flow Factors, respectively,
used for developing the model for the study area.
Non -Residential
Flow monitors were sited is areas of homogeneous non-residential land use classifications to calibrate
existing non-residential unit flow factors. The flow factors were calculated by dividing the total
homogenous basin average daily flow by the total parcel areas in acres which resulted in gpd/acre. For
build -out conditions, the unit flow factors used in previous studies were used as they were determined to
be more conservative.

Existing Unit Flow Factors and Non -Residential Build -Out Unit Flow Factors, respectively, used for
developing the model for the study area.
System Capacity Analysis
To calibrate the hydraulic model and establish the estimated flow within the pipes for dry weather
conditions, the consultant used the flow data from the temporary flow monitoring program. The dry
weather flow calibration involved adjusting unit flow rates and hourly diurnal profiles. The hourly diurnal
profiles were developed based on flow meter data.
Design flows for the build -out dry weather condition were developed and input into the model to identify
capacity deficiencies and develop capital improvement projects (CIPS). Future dry weather peak flows
were developed by applying the future flow estimates to the future unit generation rates and diurnal flow
patterns. The build -out (design) flow conditions were then run in the model and results were compared
to threshold criteria to determine capacity deficiencies.
The threshold criteria, for the build -out dry weather condition was a depth -to -diameter ratio (d/D) at the
design flow (Design Q) designated as d/D. This d/D ratio was calculated in the Hydra program and was
used to identify pipes needing improvement. The City's criteria consists of a maximum allowable d/D =
0.75 for pipe with diameters equal to or greater than twelve inches and d/D = 0.67 for pipe with diameters
less than twelve inches. Thus, pipes with d/D ratios greater than these values were identified as needing
improvement. In addition to the d/D calculations, the Hydra program calculates three flow values in terms
of cubic feet per second (cfs). These values are Qfu,l, C6a., and Qe.cess• Qr„ a is defined as the capacity of the
pipe at full flow conditions. Qrt,a. is the capacity of the pipe at a specified d/D. And, Qexcess is the difference
between Q,r,a), and the Design Q.
Design flows are typically based on a calibrated or extrapolated wet weather events or an applied
allotment to dry weather flows to account for 1/I. Although specific wet weather flow data for each study
area is not included in the Master Plans, according to the City's criteria, the recommended pipe sizes for
the improvements identified account for wet weather flow conditions.
9.2.3 Capacity Enhancement Measures
Based on the threshold criteria discussed above, a CIP for the replacement of sewer pipelines is each study
area was developed. The pipelines that require replacement for insufficient capacity were identified.
9.2.4 Schedule
The projects identified in the Master Plan for each study area address capacity limitations for dry weather
flow conditions for both existing and build -out conditions. Projects are summarized and presented
according to the number assigned to the model during its development. Also included for each study area

were estimated costs for the recommended improvements. Sources of funding for the CIP projects are
identified in the associated Financial Implementation Plan prepared for each Master Plan.
9.3 City's Continuing Capacity Assurance Plan Efforts
The City is on schedule to update the Master Plans on a 3-5 year cycle to ensure changes in demands,
populations, and land uses are incorporated. Additionally, the wastewater collection system capacity
assessment should be updated for each Master Plan, if planned development or re -development plans
change significantly, if there are changes in contracts with the Orange County Sanitation District, or if
other conditions arise that are expected to have significant capacity impacts on the system.

Public Education and Outreach
The primary objective of a Public Education / Outreach Program is to increase public awareness of sanitary
sewer system issues, to promote a sense of stewardship for the City's system and facilitate the City's
efforts towards the effective and efficient management, operation, and maintenance of the sanitary
sewer system. This chapter of the SSMP discusses the City's efforts to educate and inform the public and
affected agencies regarding the proper use of the City's sanitary sewer system.
10.1 Regulatory Requirements for Public Education and Outreach
The WDRs require the City to communicate on a regular basis with the public on the development,
implementation, and performance of its SSMP. The communication system shall provide the public the
opportunity to provide input to the City as the program is developed and implemented.
10.2 Discussion of Public Education and Outreach
The City's Public Education and Outreach Program to communicate its efforts to comply with the WDRs
and address the development and implementation of this SSMP will serve to educate, inform, and engage
key stakeholders, such as agencies that may be affected by an SSO, and businesses, developers,
contractors, vendors, and plumbers whose business could be impacted by specific requirements or
elements of this SSMP.
Through the City's Public Information Office (PIO), the City should coordinate external communications
between the City and the public regarding the implementation and on-going development of this SSMP
and its various elements. The PIO is responsible for preparing and providing pertinent information for
news releases, articles, and the website. Additionally, the PIO can work closely with the City Council, City
departments, news media, the public and affected agencies to assist in promoting an open and frequent
exchange of information necessary for the systematic and effective implementation of the various SSMP
elements.
The following includes a summary of the City's efforts to educate, inform and engage the public's support
and participation in the proper utilization of the City's sanitary sewer system and comply with the WDR
requirements.
City of Anaheim Official Website
The City's current outreach efforts include maintaining a website (http://www.anaheim.net/) to inform
the public about City activities. The City's website is an effective communication channel for providing
alerts and news to the public. The main page of the website provides access to various City departments
including the PIO, and links to diverse information, important announcements, and agendas for City
Council meetings, and other key information for City residents. The City can utilize the website to publish

its SSMP to provide the public the opportunity to view and offer input to the City as the SSMP elements
are implemented. As well, the City can utilize the website to notify the public of important upcoming
activities related to sewer system management.
City of Anaheim FOG Control Program
The public outreach element included in the FOG Control Program has included a concentrated effort to
educate FSE staff regarding proper management of FOG generated on site. During the regularly performed
site inspections, City staff provides information to FSE staff that results in the reduction of FOG discharged
into the City's wastewater collection system. Additionally, providing information via various forms of
media is an effective way to engage the public in recognizing the importance of reducing the quantity of
FOG introduced to the sanitary sewer system and the threat of excessive quantities to the potential and
actual occurrence of SSOs.
City of Anaheim Sanitary Sewer Overflow Emergency Response Plan
The SSOERP includes a Public Advisory of Sewage Contamination Procedures which includes a description
of the action that City staff must take to limit public access to surface waters and other areas that may
have been impacted by an SSO as well as notify the public of potential hazardous conditions. Examples of
signs that may be posted to provide a warning of potential public health risk are included in Attachment
H of the SSOERP. Additionally, pre -scripted notices are included in Attachment I of the SSOERP which may
be modified to accurately reflect the conditions at the time of publication and/or airing.
Should additional notification of sewage contamination be deemed necessary, City staff is required to, in
cooperation with the City's PIO, provide further notices through the use of prescripted notices made
available to the printed or electronic news media for immediate publication or airing, or by other
measures, such as door hangers.
Public Meetings
Public meetings to discuss City related issues are held regularly in the City Council Chambers located at
Anaheim City Hall at 200 South Anaheim Boulevard, Anaheim, California, 92805. The City encourages
residents to attend City Council meetings to become better informed about how the City works and
various issues. The council meetings provide the residents and concerned citizens a forum to provide the
council with input on particular programs through the Public Hearing process, and through the Citizen
Participation portion of each City Council meeting. During Citizen Participation, each person who wishes
to address the City Council on an item not on the agenda may do so. Copies of the Council Agenda are
made readily available to the public from the City's website or the City Clerk's Office. Certification of the
completed SSMP is required by the City Council during a public City Council meeting.

Public Education and Outreach
Project specific meetings may also be convened with community leaders and other citizens to discuss the
impacts, schedule and criteria of sewer related projects and efforts. These meetings give citizens a forum
to learn about the City's activities, voice their concerns, and receive clarification on a variety of issues.
Often, the project managers arrange these meetings.
10.3 Public Education and Outreach Media
A variety of means exist to educate and inform the public regarding impacts to the City's sanitary sewer
system facilities. The following list identifies several forms of media available for the City to use to educate
and inform the public:
• Bi -annual inserts in water and/or sewer bills;
• Press releases;
• Direct mailers;
• Door hangers;
• Brochures distributed at City locations and kiosks;
• Posters and flyers displayed prominently in public areas, such as on buses, libraries,
recreational centers, and so on;
• Announcements and notices placed on the City's web site;
• Announcements and notices place in the City's bi-annual Recycle Anaheim Newsletter; and
• Specific events to educate the public on the effects of SSOs to the public and environment
such as at an earth day fair, open house events, and other appropriate venues.
Included in Appendix G are examples of educational campaigns, which includes a flyer advertising that the
drain is not a dump for FOG, a door hanger presented in both English and Spanish that can be left with
residents, and best kitchen practices for businesses. Additionally, an example of text that may be included
on a postcard and mailed to residents soon after a FOG related SSO has occurred to alert people to the
effort required to clear a blockage and to reinforce not to put FOG down the drain. Translation services
may be required and anticipated during any educational campaign.
Educating the public to reduce FOG is an important task that should have a specific amount of time
dedicated to its success. Investment up front in educating the public, will reduce the financial expenditure
in responding to and mitigating FOG related SSOs as they will be effectively reduced. Staff from the Public
Works Operations Division and other affected departments should work closely with the City's PIO to
develop appropriate messages and with which media the messages should be disseminated.
Additionally, the City intends to communicate on a regular basis with interested parties on the
implementation and performance of this SSMP. The Public Education and Outreach Program will allow
interested parties to provide input as the SSMP and its elements are developed and implemented.

Monitoring, Measurement, and Program Modifications
This chapter of the SSMP discusses the parameters the City will utilize to track and monitor the progress
of implementing elements of the SSMP, the effectiveness of the SSMP, and how the City intends to update
and revise the SSMP to keep it current.
11.1 Regulatory Requirements for Monitoring, Measurement, and Program Modifications
The WDRs require the City to:
a) Maintain relevant information that can be used to establish and prioritize appropriate
SSMP activities;
b) Monitor and implement and, where appropriate, measure the effectiveness of each
element of the SSMP;
C) Assess the success of the Preventative Maintenance Program;
d) Update program elements, as appropriate, based on monitoring or performance
evaluations; and
e) Identify and illustrate SSO trends, including: frequency, location, and volume.
11.2 Discussion of Monitoring, Measurement, and Program Modifications
To date, the City has effectively managed and maintained information pertaining to the wastewater
infrastructure by means of manually recording preventive maintenance activities and documenting
notifications received regarding potential and actual SSO occurrences. The City has tracked performance
measures through logs and reports including, but not limited to, the length of pipe cleaned, the quantity,
cause and location of stoppages, SSOs, and the scheduled maintenance of high frequency maintenance
locations. The City will continue to monitor the performance measures it currently tracks.
To address the components listed in Section 11.1 and as required by the WDRs, the following subsections
provide a summary of the procedures to properly monitor program progress and implement necessary
modifications.
11.2.1 Maintain Information Pertaining to SSMP Activities

The City developed the 0&M Program that includes a summary of the City's current procedures and
practices as they pertain to the O&M activities. On a regular basis, at least once every two (2) years, the
City should evaluate the effectiveness of the 0&M Program elements and staffing levels.
Recommendations for appropriate adjustments and an implementation schedule should be developed.
Implementation of any changes should be based on urgency of the need, coordination with other program
elements, and management approvals.
11.2.4 Update Program Elements
The City must review this SSMP on a regular basis and update the document with any significant changes.
The SSMP must be reviewed, updated, and re -certified at least once every five (5) years. The City's process
should include distributing the SSMP to appropriate City staff for review to ensure the most current legal
authority, response plans, organizational charts, equipment lists, and contact/notification information is
included. Once the City makes operational, maintenance, management, and administrative changes, the
City may consider distributing the SSMP to other agencies to perform a peer review of the document.
Once recommendations are incorporated into the document, the SSMP will be ready for public
dissemination and ultimately for recertification by the City Council. The City is responsible for maintaining
the SSMP program as required by the Santa Ana RWQCB and will make the SSMP accessible to the public.
