EXECUTIVE SUMMARY
Asset Management Plan Purpose
Over the past two years, Orange County Sanitation District (OCSD) has made a concerted effort
to establish an updated and more robust understanding of the condition and performance of all
critical and major assets and our ability to meet established levels of service. As OCSD
embarks on another year of this renewed asset management program, we have updated our
Asset Management Plan to be a tactical document summarizing our plans for addressing asset
condition and performance issues.
This Asset Management Plan will be published annually, and we anticipate this document will
continue to change in content and structure as our asset management program evolves.
Overview of OCSD’s Infrastructure
OCSD is responsible for providing wastewater collection, treatment and recycling services to
over 2.6 million people in central and northern Orange County, California. OCSD’s two resource
recovery and wastewater treatment facilities treat an average daily wastewater flow of 185
million gallons per day (MGD) from residential, commercial and industrial sources.
OCSD owns and operates wastewater collection system infrastructure as well as resource
recovery and wastewater treatment facilities. Our collection system infrastructure includes 389
miles of regional trunk sewer pipelines and fifteen pump stations located throughout OCSD’s
service area. This wastewater is conveyed to Reclamation Plant No. 1 in Fountain Valley and
Treatment Plant No. 2 in Huntington Beach, where resource recovery and wastewater treatment
take place.

Asset Management Intent, Policy, and Initiatives
Reliable infrastructure is essential to achieving our mission and vision. We manage
infrastructure reliability according to the following stated intent for our asset management
program:
“OCSD will know the condition of assets we own and will have a
plan to operate and maintain these assets to deliver the required
level of service at the lowest life cycle cost with an acceptable
level of risk.”
~ James D. Herberg, OCSD General Manager
In November 2019, OCSD’s strategic planning process resulted in the creation of an Asset
Management Policy and Asset Management Initiatives.
ASSET MANAGEMENT POLICY
The Sanitation District will assess and manage the collection system and treatment plant
systems and assets to improve resilience and reliability while lowering lifecycle costs. This will
be accomplished through adaptive operation, coordinated maintenance and condition
assessment, and planned capital investment. Staff will balance maintenance, refurbishment,
and replacement strategies to maximize useful life, system availability and efficiency.
ASSET MANAGEMENT INITIATIVES
Create an annual Asset Management Plan documenting the condition of the collection
system and treatment plants, and upcoming maintenance or capital projects.
Coordinate the efforts of operations, collections, mechanical maintenance, electrical

Asset Management Organization
Asset management is not new to OCSD. As shown in Figure ES.2, every part of our
organization is involved in some aspect of ensuring assets are designed, constructed, operated,
and maintained to reliably deliver service to our customers.
Figure ES.2. Roles in Asset Management
To fulfill our commitment to our ratepayers for providing safe and reliable services, OCSD has
augmented and solidified our asset management program and restructured the organization to
better align the Engineering and Operations and Maintenance (O&M) departments. Through this
restructuring, OCSD has established an Asset Management Group within the Planning Division
consisting of nine Asset Engineers responsible for understanding the key issues or concerns
related to the condition of OCSD’s assets and for developing and coordinating plans to ensure
these assets operate reliably.

State of OCSD’s Infrastructure
The following system-level summary tables provide a high-level overview of the Area Asset
Management Summaries contained in CHAPTER 5. The system-level summaries are organized
by:
Plant No. 1 (Table ES.1)
Plant No. 2 (Table ES.2)
Collection System – Pump Stations (Table ES.3)
Collection – Pipelines (Table ES.4)
The system-level summaries generally include the following fields:
Area No.
Area Name
Average Remaining Useful Life (RUL) Score: Estimated average RUL score for each
discipline (civil, structural, mechanical, electrical, and instrumentation) or area based on
an average of the RUL scores provided by Asset Engineers in the detailed Area AM
Summaries.
Percentage of RUL Scores with 4s or 5s[1]: Percentage based on total number of RUL
scores assigned to each area by Asset Engineers in the detailed Area AM Summaries.
The percentage is an alternate metric for the overall condition of the area. A RUL score
of 5 indicates less than 5 years of useful life remains for an asset or set of assets. A RUL
score of 4 indicates 5 to 10 years of useful life remains for an asset or a set of assets.
Replacement Value ($million): Process area replacement value from the facility
valuation.

CHAPTER 1 PURPOSE
Over the past two years, the Orange County Sanitation District (OCSD) has made a concerted
effort to establish a baseline understanding of the condition and performance of all critical and
major assets and our ability to meet established levels of service. As OCSD embarks on
another year of this renewed asset management program, we have updated our Asset
Management Plan to be a tactical document summarizing our plans for addressing asset
condition and performance issues.
This Asset Management Plan will be published annually, and we anticipate this document will
continue to change in content and structure as our asset management program evolves. The
current structure is organized into the following chapters to meet the needs of stakeholders:
Executive Summary: Summarizes purpose of the Asset Management Plan and main
conclusions.
Chapter 1 Purpose: Outlines purpose and organization of the Asset Management Plan.
Chapter 2 Overview of OCSD’s Infrastructure: Describes the major infrastructure that
OCSD owns and operates.
Chapter 3 Asset Management Intent, Policy and Initiatives: Defines organizational
intents, policies, and initiatives driving the asset management program.
Chapter 4 Asset Management Organization: Describes the asset management
organizational structure and asset management strategies.
Chapter 5 State of OCSD’s Infrastructure: Summarizes the current state of OCSD’s
infrastructure and plans to address asset condition and performance issues.
Chapter 6 Program Monitoring and Improvements: Documents activities to monitor
the asset management program and improvement opportunities.

CHAPTER 2 OVERVIEW OF OCSD’S INFRASTRUCTURE
OCSD is responsible for providing wastewater collection, treatment and recycling services to
over 2.6 million people in central and northern Orange County, California. OCSD’s two resource
recovery and wastewater treatment facilities treat an average daily wastewater flow of 185
million gallons per day (MGD) from residential, commercial and industrial sources.
OCSD owns and operates wastewater collection system infrastructure as well as resource
recovery and wastewater treatment facilities. Our collection system infrastructure includes 389
miles of regional trunk sewer pipelines and fifteen pump stations located throughout OCSD’s
service area (shown in Figure 2.1). This wastewater is conveyed to Reclamation Plant No. 1 in
Fountain Valley and Treatment Plant No. 2 in Huntington Beach, where resource recovery and
wastewater treatment take place.
OCSD’s treatment plants currently operate under a permit from the Regional Water Quality
Control Board (RWQCB). This was established by the National Pollutant Discharge Elimination
System (NPDES) that permits the discharge of treated wastewater through an ocean outfall
system to the Pacific Ocean. While some of this treated water is released five miles offshore
through a deep-water ocean outfall system, most is recovered and delivered to Orange County
Water District (OCWD). OCWD further treats OCSD’s effluent using the Groundwater
Replenishment System, which improves the effluent water quality to drinking water standards
for groundwater recharge and irrigation purposes. The following sections briefly describe the
key systems under OCSD’s management.
14
Figure 2.1. OCSD Service Area
15
2.1 Collection System
OCSD’s collection system serves as a regional conveyance system, collecting and conveying
flows from 20 cities and four special districts. OCSD's 389 miles of collection system pipelines
and 15 pump stations are spread throughout northern Orange County and include 365 miles of
gravity pipelines, 20 miles of force mains, four miles of inverted siphons and 4,471 manholes
structures.
16
2.2 Treatment Plant System
OCSD owns and operates two wastewater treatment plants. Reclamation Plant No. 1 is
located in the City of Fountain Valley, approximately four miles inland of the Pacific Ocean and
adjacent to the Santa Ana River (shown in Figure 2.2). Influent wastewater entering
Reclamation Plant No. 1 passes through a flow metering and diversion structure, mechanical
bar screens, grit chambers, and primary basins, before going to one of two air activated sludge
processes or trickling filters and secondary basins. Up to 135 MGD of secondary effluent can be
diverted to OCWD’s facilities for tertiary treatment prior to reuse.
Figure 2.2. Aerial View of Reclamation Plant No. 1
Solids treatment at Reclamation Plant No.1 includes co-thickening of primary and secondary
sludge, followed by anaerobic digestion process and centrifuge dewatering of digested sludge to
produce Class-B biosolids. Digester gas produced at Plant No. 1 is collected, compressed,
cleaned, and transferred to the Central Power Generation Facility as a renewable fuel for
energy generation. Plant No. 1 also has facilities for odor control and chemical addition.
17
Treatment Plant No. 2 is located in the City of Huntington Beach, adjacent to the Santa
Ana River and east of Pacific Coast Highway (shown in Figure 2.3). Raw sewage flow entering
Treatment Plant No. 2 passes through a flow metering structure, mechanical bar screens and
grit removal chambers. Flow then passes through primary basins before being split between the
oxygen activated sludge secondary treatment facility or trickling filters/solids contact and is
discharged directly to the ocean via the outfall pumping system.
Figure 2.3. Aerial View of Treatment Plant No. 2
Solids treatment at Treatment Plant No. 2 includes in-basin thickening of primary sludge,
dissolved air flotation thickening of waste activated sludge and secondary sludge, anaerobic
sludge digestion and centrifuge dewatering. Plant No. 2 also has facilities for odor control and
chemical addition. Digester gas produced at Plant No. 2 is collected, compressed, cleaned, and
distributed to a Central Power Generation System as a renewable fuel for energy generation.
18
2.3 Outfall System
The ocean outfall system includes three discharge structures: Outfall No. 1, Outfall No. 2, and
the Santa Ana River Emergency Overflow Weirs.
Outfall No. 2 serves as the primary ocean outfall, discharging treated wastewater
approximately five miles offshore at a depth of approximately 200 feet. It began service in 1971.
Outfall No. 1 serves as an emergency outfall. It was originally constructed in 1954 and
modified in 1965. It is located over a mile offshore at a depth of approximately 65 feet. OCSD’s
NPDES permit specifies that this outfall can only be used in the case of an emergency or
maintenance.
The Outfall System has two Santa Ana River Emergency Overflow Weirs at Plant No. 2
which discharge directly to the Santa Ana River. These weirs are for extreme emergency use
only.
19
2.4 Facility Valuation
As part of the 2017 Facilities Master Plan, OCSD commissioned consulting engineering firms to
conduct a study to determine the 2017 value of all OCSD capital facilities, including
Reclamation Plant No. 1, Treatment Plant No. 2, interplant and joint treatment facilities, and the
collection system, including sewer pipelines and lift stations.

CHAPTER 3 ASSET MANAGEMENT INTENT, POLICY AND
INITIATIVES
The Asset Management Plan is prepared in alignment with OCSD’s Mission, Vision, Asset
Management Policy and Asset Management Initiatives approved by our Board of Directors.
OCSD’s Asset Management Initiatives serve as a means for tracking progress towards meeting
asset management objectives along with other performance measures.
22
This Asset Management Plan is a key component of OCSD’s overall planning activities. It is
aligned with the District’s Strategic Plan, includes projects identified in the Facilities Master
Plan, and identifies potential new activities requiring funding in the budget development
process. Table 3.1 describes the relationship of the Asset Management Plan to other planning
activities.

3.1 OCSD Mission and Vision Statements
OCSD’s Board of Directors developed Mission and Vision statements to clearly communicate
OCSD’s purpose to our stakeholders and to articulate OCSD’s organizational objectives.
OCSD’s Vision supports our Mission by expressing what we strive to achieve now and into the
future.
OUR MISSION
To protect public health and the environment by providing effective wastewater
collection, treatment and recycling services.
OUR VISION
OCSD will be a leader in:
Providing reliable, responsive, and affordable services in line with customer
needs and expectations.
Protecting public health and the environment utilizing all practical and effective
means for wastewater, energy, and solids resource recovery.
Continually seeking efficiencies to ensure that the public’s money is well
spent.
Communicating our mission and strategies with those we serve and all other
stakeholders.
Partnering with others to benefit our customers, this region, and our industry.
Creating the best possible workforce in terms of safety, productivity, customer
service, and training.
We are achieving this mission through improved asset management practices to better
coordinate and plan actions to ensure our collection system, treatment and resource recovery
infrastructure works when we need it.
One of the ways we are doing this in asset management is by defining clear roles and
responsibilities for identifying the condition and performance needs of our assets. We work as a
team to develop solutions and coordinate our efforts to solve these issues before they become
problems that impact our ability to achieve our mission. This Asset Management Plan
documents the key condition and performance issues identified by OCSD staff and our
collective plans for addressing these issues.
24
3.2 Strategic Plan – Asset Management Policy and Initiatives
Reliable infrastructure is essential to achieving our mission and vision. The stated intent of
OCSD’s General Manager is:
“OCSD will know the condition of assets we own and will have a plan to
operate and maintain these assets to deliver the required level of service at
the lowest life cycle cost with an acceptable level of risk.”
– James D. Herberg, OCSD General Manager
Related to the intent, the key objectives we are building into the asset management program
include:
Proactive approach to repair, rehabilitation and replacement.
Ensure assets are reliable and operating when needed.
Minimize unplanned outages and equipment downtime.
Manage risks associated with asset or service impairment through asset performance
optimization.
Develop cost-effective management strategies for the long term.
Strive to implement world class asset management strategies through continual
improvement in our asset management practices.
In addition, OCSD has a biennial strategic planning process designed to accomplish the
following objectives:
Affirm corporate mission and vision.
Adjust strategic goals and policies.
Set agency-wide prioritization of initiatives.
Provide a disciplined budgeting process.
Set operational goals at the operating level.
Hold individual units accountable for performance.
25
The biennial strategic planning process is instrumental to aligning the activities OCSD’s staff
performs with the strategic intent of the Board of Directors. In November 2019, OCSD’s
strategic planning process resulted in the creation of an Asset Management Policy and Asset
Management Initiatives.
ASSET MANAGEMENT POLICY
The Sanitation District will assess and manage the collection system and treatment plant
systems and assets to improve resilience and reliability while lowering lifecycle costs. This
will be accomplished through adaptive operation, coordinated maintenance and condition
assessment, and planned capital investment. Staff will balance maintenance, refurbishment,
and replacement strategies to maximize useful life, system availability and efficiency.
ASSET MANAGEMENT INITIATIVES
Create an annual Asset Management Plan documenting the condition of the collection
system and treatment plants, and upcoming maintenance or capital projects.
Coordinate the efforts of operations, collections, mechanical maintenance, electrical
maintenance, instrument maintenance and engineering through process teams to assure
the Sanitation District’s resources are focused on the high priority work functions.
Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade the
Sanitation District’s nearly $11 billion in assets on a prioritized risk basis to establish rate
structures.
Continual improvement in asset management practices is important. We are actively working to
improve our implementation of the key objectives and our asset management capabilities,
processes and systems through improved coordination in needs identification, solutions
development, and project execution.
This Asset Management Plan provides a summary of the condition of the collection system and
treatment plants in CHAPTER 5 along with the upcoming maintenance and capital projects.
CHAPTER 4 describes our approach to coordinating and focusing our efforts on high priority
work functions.

CHAPTER 4 ASSET MANAGEMENT ORGANIZATION
Asset management is not new to OCSD. Every part of our organization is involved in some
aspect of ensuring assets are designed, constructed, operated, and maintained to reliably
deliver service to our customers.
Figure 4.1. Roles in Asset Management
Operations operates assets to convey, treat and recover resources.
Maintenance performs activities to maintain asset reliability.
Engineering Planning provides engineering support for short- to long-term
management of assets.
Project Management manages design and construction of new facilities and the
rehabilitation of older facilities.
Engineering Design ensures projects and assets are designed to meet stakeholder
needs.
Construction Management ensures assets are constructed in accordance with contract
requirements.
To fulfill our commitment to our ratepayers for providing safe and reliable services, OCSD has
augmented and solidified our asset management program and restructured the organization to
better align the Engineering and Operations and Maintenance (O&M) departments. Through this
restructuring, OCSD has established an Asset Management Group within the Planning Division
consisting of nine Asset Engineers responsible for understanding the key issues or concerns
related to the condition of OCSD’s assets and for developing and coordinating plans to ensure
these assets operate reliably. The Asset Engineers work closely with O&M Area Team
28
members to maintain familiarity with operational, condition, and maintenance issues within their
assigned areas.
4.1 Asset Management Coordination and Solutions Development
The Area Teams are the starting point for leveraging field data to define issues requiring
remediation. Area Teams are made up of plant operators, mechanics, electricians, instrument
technicians and Asset Engineers. Figure 4.2 shows how field data is used to support
coordination and solutions development for reporting issues to management and gaining project
approval.
Coordination: Asset Engineers coordinate with O&M staff to understand asset
conditions and needs based on staff knowledge, condition assessments (e.g., closed-
circuit television [CCTV], corrosion assessments) and predictive maintenance data
(e.g., vibration, infrared, oil quality). Asset Engineers update the area asset registries
with estimated remaining useful life and relevant notes. Asset Engineers compile key
issues and coordinate potential remediation activities, which are then presented to the
Asset Management Council, consists of managers from all divisions within OCSD, during
monthly presentations.
Solutions: Asset Engineers support solutions development and tracking. OCSD has
developed SharePoint sites to track asset issues (i.e., Asset Issues Tracker) and to track
solutions to asset issues executed by other divisions. Asset Engineers also define and
prepare the potential work packages for the Clearinghouse review and approval. The
Clearinghouse consists of managers from all OCSD divisions who come to a common
understanding of issues facing OCSD and prioritize resources necessary to address
those issues. After the project is approved by the Clearinghouse, it is turned over to a
project team for execution.
There are two sources of funding that may be used for projects approved by the Clearinghouse:
Operating Budget and Capital Improvement Program.
The two-year Operating Budget is adopted biennially with an annual update. This budget
includes funding for all programmed maintenance work and repairs to the facilities and
infrastructure.
The Capital Improvement Program sets aside funds for projects that are planned to
rehabilitate, replace, or extend the useful life of the facilities and infrastructure.
29
Figure 4.2. Coordination and Solutions Development Processes
The following subsections describe the groups involved in the coordination and solutions
development process of asset management.
4.1.1 Operations and Maintenance
Area Teams
The O&M Department has created Area Teams assigned to various process areas within the
two wastewater treatment plants with the vision of being a top-notch, high-performing team that
increases process efficiency and asset availability.
The Area Teams consist of staff from operations and maintenance covering mechanical,
instrumentation and electrical disciplines. Each Area Team is assigned an Area Champion
(typically a supervisor) who assists the team through challenges, and aids in team collaboration
and oversight. The Area Team is also assigned representatives from maintenance planning and
an Asset Engineer from the Planning Asset Management Group (see Subsection 4.1.2).
The teams help streamline efforts and align resources within the current organizational structure
to integrate the skills, knowledge and insights from all levels of operations, maintenance and
engineering. O&M Area Team members provide the Asset Engineer with a direct line of
30
communication to field staff operating within the process areas and serve as a central resource
for information sharing and collaboration for solution development.
4.1.2 Engineering Planning
OCSD’s Planning Division provides a comprehensive Capital Improvement Program (CIP) that
considers projected capacity requirements, condition of current assets, projected regulatory,
level of service changes and business opportunities.
Capital Improvement Program Planning
The Planning Division’s CIP Planning Group develops and maintains the 20-year CIP plan
consisting of capital improvement projects that maintain reliability, accommodate future growth,
as well as meet future regulatory requirements, level of service goals, and strategic initiatives.
In 2017, the OCSD Board of Directors adopted the Facilities Master Plan which provides a 20-
year roadmap setting forth OCSD’s long term Capital Improvement Program. This roadmap
provides a framework for infrastructure improvements needed at our treatment plant facilities,
15 pump stations, and 389 miles of regional sewers. In the 2017 Facilities Master Plan, most of
the projects identified are the result of the need to rehabilitate and replace aging infrastructure in
the collection system and treatment plants.
Asset Management
The Asset Management Group within the Planning Division consists of nine Asset Engineers
who are responsible for OCSD’s short- to long-term asset management goals. The primary
responsibility of this group is to monitor the condition of assets, develop short to long-term
planning for asset maintenance, rehabilitation and replacement, and identification, packaging
and prioritization of maintenance and CIP projects.
Asset Engineers are assigned to one or more defined process or collection system areas. They
work closely with O&M to maintain familiarity with operational, condition, and maintenance
issues within their assigned areas. They also serve as “ambassadors” for each of their assigned
areas to ensure that high priority issues are addressed in a timely fashion, and as the first point-
of-contact for asset issues to drive root cause analysis and condition assessment. The Asset
Management group plans and conducts condition assessments of critical assets utilizing
corrosion consulting engineers, and CCTV contracts (Figure 4.3).
Asset Engineers also engage with
maintenance and capital improvement
project delivery teams to monitor the
scope of work and timing of planned
projects, to verify that the projects will
address the identified issues in a timely
manner. One of their key responsibilities
is to define the scope, appropriate timing
and budget requirements of future
maintenance and CIP projects, which are
the basis for future project, operations,
and maintenance budget development.
Moving forward, the Asset Engineers will
have the primary responsibility for
submitting CIP projects for Clearinghouse
approval.
Knowing the history, background
information and the future plans for each specific area, the Asset Engineers are in a unique
Figure 4.3. CCTV Inspection
31
position to coordinate asset maintenance and rehabilitation activities among various OCSD
divisions. These coordination efforts support the goal of OCSD’s Asset Management Program,
which is to lower lifecycle costs of infrastructure, at an acceptable level of risk, while
continuously delivering OCSD’s established levels of service.
Figure 4.4 illustrates the role Asset Engineers have in gathering information and understanding
needs to support coordination, planning and communication of changes to the plans.
Figure 4.4. Asset Engineer Role within Asset Management

4.2.1 Project Management Office
OCSD’s Project Management Office Division manages the design and construction of new
facilities plus the rehabilitation of existing facilities to ensure the safe, cost effective transport,
and treatment of influent/effluent. This division is responsible for the delivery of projects from the
preliminary design stages through closeout of construction. The division provides standards,
processes, and methodologies to improve project quality, cost, and timeliness.
Small Project Delivery
The Small Projects Delivery team is a support arm of the Operations, Maintenance, and
Engineering divisions and is responsible for the design and construction of facilities and
maintenance projects. The purpose of this team is to deliver short term projects to effectively
manage life of existing assets and in doing so deferring construction of capital projects in the
longer term.
Project Engineers in the Small Projects Delivery team completes the scope of work, performs
project design (in-house or by consultant), bids the project in collaboration with Contracts or
Purchasing, and manages construction, implementation, commissioning, change management,
and closeout.

The Project Delivery Support group supports the CIP and small projects with reporting and
monitoring tools for budgets, costs, schedules, cost estimates, amendments, change orders,
and resource and cash forecasting for all projects.
4.2.2 Design
The Design division ensures that all projects are designed and constructed to be reliable,
maintainable, and operable at optimum lifecycle costs in accordance with OCSD’s Engineering
Standards and codes. The division also ensures that the electrical and control systems on
projects are properly and safely constructed, commissioned, and executed in accordance with
the contract documents with minimal impact to operations, maintenance, local agencies, and the
public. The division provides process control SCADA system hardware, software and data
network support for collections and treatment plant processes that are highly reliable, safe,
secure, online, and available to monitor, record, control, and operate our facilities. This
division’s role is also to provide commissioning support services during construction.

4.3 Asset Maintenance
The Maintenance division provides reliable maintenance to OCSD’s assets. Maintenance-
related asset management involves implementing strategies that ensure OCSD’s assets will
operate at a required level of service and the lowest lifecycle cost with an acceptable level of
risk.
33
4.3.1 Maintenance
Maintenance Reliability Group
OCSD has developed a mature predictive maintenance (PdM) program, which is a core strategy
for maximizing asset reliability for major rotating mechanical and electrical equipment. The
premise of PdM is that regular monitoring of the actual mechanical condition of machine trains
will lead to optimal intervals between repairs, minimize the number and cost of unscheduled
repairs created by machine-train failures, and improve the overall equipment reliability.
The Reliability Technicians
use various techniques such
as:
Vibration analysis to
measure imbalance in
rotating equipment.
Thermography to
measure excessive
heat.
Oil and wear debris
analysis to predict
failure of lubricants.
Ultrasound inspection
of electrical power
distribution equipment
for detecting potential
for arc flash incidents
and mechanical rotating and
stationary equipment.
OCSD has a two-decade history of predictive maintenance as summarized in Table 4.1.
Table 4.1. High-level Summary of OCSD’s PdM Program
Year Activity
2002 Baseline vibration monitoring with consultant assistance
2006 Comprehensive vibration analysis program implementation at both treatment plants and 15
pump stations

OCSD’s predictive maintenance and monitoring program is organized around the mechanical,
electrical and civil disciplines.
Figure 4.5. PdM Summary
34
Mechanical Discipline
The mechanical discipline has the most mature PdM
Program and involves variance trending of the PdM
test results, which include:
Vibration analysis
Oil analysis
Ultrasonic
Infrared thermography
IRIS motion camera (measures deflection and
displacement)
In addition to PdM activities for mechanical
equipment, OCSD also uses laser alignment techniques to enhance alignment rotating
machinery accuracy to increase operating life span.
Electrical Discipline
The electrical PdM Program continues to evolve
and currently includes the following tests:
Oil analysis for transformers
Ultrasound to detect arcing
Infrared thermography to detect hot
spots
Electrical power distribution equipment
preventive maintenance
Circuit breakers and protective relays
preventive maintenance and testing
Future tests expected to be added include:
Motor/generator circuit analysis
Medium voltage feeder cable testing to
determine the health of cables and
insulation
Civil Discipline
Civil maintenance covers proactive and corrective maintenance tasks for all OCSD civil assets
at all facilities located at Plants No. 1 and No. 2, as well as all OCSD pump stations and
collection system. Civil maintenance activities complement the existing maintenance programs
for mechanical, electrical and instrumentation. Civil maintenance includes the following
activities:
Valve and gate exercising program comprising more than 264 preventive maintenance
tasks for over 1,650 valves and gates in both plants and collection system.
Equipment rotation program to ensure equipment wear is predictable.
Operating, maintaining and cleaning pump stations and associated facilities.
Chemical conditioning of the sewage to reduce corrosion and control odors.
Figure 4.6. Vibration Analysis Equipment
Figure 4.7. Infrared Thermography
35
In addition to these activities, OCSD also implements life extension measures to increase the
useful life of expensive equipment through minor repairs, and corrosion control methods such
as coatings and cathodic protection.
Routine Maintenance
Beyond the advanced predictive maintenance strategies used to cost-effectively extend
equipment life, OCSD also performs routine time and cycle-based preventive maintenance (PM)
activities including:
Adjustments and mechanical alignments
Electrical equipment cleaning and tightening
Sensors and meters calibration
Changing of lubricants and filters
Exercising equipment
Equipment rebuilding and regular testing
Preventative Optimization
OCSD created a new Preventative Maintenance Optimization Group that will be tasked with
conducting an in-depth assessment to optimize planned maintenance strategies for new and
existing assets and to establish maintenance approaches and strategies for assets installed by
capital improvement projects prior to beneficial occupancy. The PM Optimization Program will
track, maintain, and manage assets throughout their lifecycles from design, construction,
commissioning, beneficial occupancy, operations and maintenance, to the eventual
decommissioning or replacement of assets.
This will ensure that asset lifecycle is maximized with the lowest risk to process failure by
achieving the intended reliability, at the lowest possible cost, and maximizing equipment
availability.
Maintenance Planners
Maintenance Planners are responsible for managing blanket maintenance service contracts,
planning and scheduling of craft-based maintenance activities, optimizing preventive
maintenance activities within Maximo, and coordination of complex maintenance activities
involving shutdowns and outages.
Maintenance Planners help drive reliability and effectiveness in the craft-based maintenance
work groups they support by ensuring that work groups have sufficient ready-to-execute work
with appropriate resources such as tools, materials, labor, and job plans.
Maintenance Planners are the owners of preventive maintenance and job plans. They are
responsible for maintaining preventive maintenance and job plan database within Maximo. They
continuously improved preventive maintenance by fine tuning job plans based upon input
received from field staff, leads, maintenance Supervisors and Engineers.

CHAPTER 5 STATE OF OCSD’S INFRASTRUCTURE
The Area AM Summaries are intended to summarize the condition of major assets, identify key
issues for further investigation, and summarize maintenance and CIP projects planned over the
next ten years. The approach for developing the AM Summaries is to assemble a list of major
assets, document key issues, define the average remaining useful lives of these assets, and
identify OCSD’s plan to address performance and reliability issues of these assets over the one,
five-, and ten-year planning horizons.
Every AM Summary is presented to the AM Council once annually. Each month, an Asset
Engineer presents one or more of the AM Summaries to the AM Council. The Area AM
Summaries are updated as needed and incorporated into the AMP which is published annually.
Asset Engineers maintain a detailed asset registry which is a primary data source for the Area
AM Summaries. The asset registries generally include the fields shown in Table 5.1.

ASSET MANAGEMENT SYSTEM SUMMARY – AREA 10 – PLANT NO. 1 PRELIMINARY TREATMENT
Key Issues
Key Issues Actions and Recommendations
P1-105 Construction – This project will rehabilitate most assets
throughout the preliminary treatment area, however the construction
completion date is far in the future. Some assets have very little
remaining life or have failed already and will need interim solutions
before they are addressed by the project.
Continue to actively monitor the condition of aging assets scheduled for
repairs/replacement under P1-105 and develop temporary/minimal solutions
as applicable until a permanent solution is provided by P1-105. In some
instances, failed equipment may need to be replaced and removed from the
P1-105 scope, but this approach should be minimized.
Steve Anderson Lift Station – Steve Anderson Lift Station has
experienced vibration issues and equipment failures over the past few
years.
New pumps without vibration issues are being installed to replace the
existing pumps. These replacements are planned to continue until all four
pumps have been replaced. Vibration of the new pumps should continue to
be monitored to confirm their performance.
Rags – Rags have become an ongoing issue throughout the
preliminary and primary process areas. The prevalence of rags is
likely due to the rise in popularity of “flushable wipes”. Rags passing
the barscreens have caused failures and increased wear on various
mechanical equipment.
P1-105 will be replacing the existing 1-inch barscreens with 5/8-inch
barscreens. This should reduce the number of rags passing the barscreens
into the treatment process.

ASSET MANAGEMENT SYSTEM SUMMARY – AREA 11 – PLANT NO. 1 PRIMARY TREATMENT
Key Issues
Key Issues Actions and Recommendations
Rectangular Primary Basin – The rectangular
primary basins experience relatively frequent
issues that require maintenance. These issues
require ongoing attention from maintenance and
can affect Plant No. 1 treatment capacity.
A number of projects are planned to address rectangular primary basin issues and reliability
including MP-462, P1-133, and X-017. However, these projects cannot make the rectangular
basins maintenance free. OCSD should expect to dedicate a significant amount of maintenance
labor to these basins, especially during times when capacity is reduced by projects. Also, a
planned Preventative Maintenance approach should be taken for continued maintenance on the
mechanical parts within the basins after work is complete on MP-462.
Construction Sequencing – There are many
upcoming projects that will perform work on the
Plant No. 1 primary treatment system. These
projects are largely interdependent on one another
and will temporarily impact the primary capacity at
Plant No. 1.
Continue to holistically assess the capacity/treatment consequences of the upcoming projects,
especially if schedules change during design and construction. Perform a study to understand if
phasing the replacement of the circular primary basins under P1-126 is feasible.
GWRS Final Expansion – The final expansion of
OCWD’s GWRS system is expected to be
complete in 2023 and will produce 130 MGD of
purified recycled water. This will require OCSD to
provide more flow to OCWD.
OCSD is executing a number of projects to prepare for the GWRS Final Expansion. The most
directly applicable is P2-122 which will provide additional flow to OCWD from Plant No. 2 while
also increasing OCSD’s flexibility to route flows between Plant No. 1 and Plant No. 2. The
optimization of flow routing will be an ongoing consideration for OCSD operations and should be
periodically re-evaluated as operating conditions change.

Key Issues Actions and Recommendations
High Rate Mixing Pumps mechanical seals failure – The high rate
mixing pumps are experiencing higher than expected failures of the
mechanical seals.
There are several efforts by Maintenance and Engineering to reduce the
failure rate including precision alignment of the pumps, studying sludge
piping supports (PS19-01) and monitoring the vibrations.
Structures – Seismic risk. The PS15 - 06 Seismic Evaluation of Structures at Plant Nos. 1 and 2 has
identified lateral Spreading as the main seismic risk for the digesters.

ASSET MANAGEMENT SYSTEM SUMMARY – AREA 17 – PLANT NO. 1 UTILITIES
Key Issues
Key Issues Actions and Recommendations
Plant/Instrument Air Lines – Severe
corrosion issues.
Current plan is to run to fail and repair the lines as they fail. In addition, if opportunity arises through future
CIP or FE projects within areas where known air system deficiencies exist, we will address them at the time.
City Water Pump Station – Pumps
are possibly undersized.
The three medium pumps at the City Water Pump Station continuously run causing excessive wear. There
are 1 smaller jockey pumps that run very infrequently. Study is needed to properly size the pumps at the
station to meet the current needs of the plant.
Reclaimed Water System – This
system needs a pressure regulating
valve installed.
Reclaimed water is meant to be a back up to plant water and to provide necessary support to Central
Generation. When the pressure on the plant water side drops, the plant becomes in need of reclaimed water
to compensate for the loss. Currently, the reclaimed water pressure varies between 100psi to 130psi,
depending on the operational conditions at OCWD. OCSD plant water is at 80 psi, so with the current valves,
reclaimed water with the higher psi tends to replace plant water, even when we are not in need. This causes
unnecessary reclaimed water charges. Installing a pressure regulating valve at the OCWD/OCSD reclaimed
water connection point will help reduce unnecessary charges and better manage our reclaimed water usage.

Key Issues
Key Issues Actions and Recommendations
Headworks Low Voltage Cable– There are 480V cables and circuits that are currently
grounded, causing ground faults on 480 volt equipment. Last incident happened in July 2019,
when the Grit Classifier A was lost due to the ground fault. Due to the complexity of the repair
job and its impact to operations, need to develop a replacement plan for known failed cables.
880E located a spare wire for the Grit Classifier A and put back in service.
PRN-00409 P2 Headworks 480V Grounded Cable Repair was approved by the Clearinghouse to do the engineering
design in-house and bid for service contract for repairs on damaged cables. The bid was awarded and will be
presented to the December board for approval.
Main Sewage Pump System – P2-122 Headworks Modifications at Plant No. 2 for GWRS
Final Expansion will replace 3 of 7 MSP pumps, but use the existing VFDs and Motors. They
are due for overhaul to ensure that they continue to be reliable during and beyond the P2-122
construction. Also, current vibration monitoring system, which is Emerson CSI 4500, for MSP
is obsolete and no longer supported after this year.
Variable frequency drives are halfway through their anticipated life cycle, so PRN-00528 P2 MSP Variable Frequency
Drive Year 10 Preventative Maintenance was approved by the Clearinghouse to perform Year 10 Preventative
Maintenance on the drives by the original equipment manufacturer.
PRN-00529 Plant No. 2 MSP Motor Overhaul was approved by the Clearinghouse to have the motors overhauled in
the motor shop
Recommend replacing the obsolete vibration system with GE Bently Nevada since the District plans to standardize
the vibration monitoring system.
Headworks – Asset life of P2-66 Headworks is relatively new, since it was completed in
2012. No condition assessment has been done in the past. There is a need to perform
condition assessment at the Headworks to build a condition baseline.
With P2-122 construction starting next year, area engineer will coordinate with the project team and Operation and
Maintenance to conduct condition assessments on areas that will be down for the construction.

Key Issues
Key Issues Actions and Recommendations
Reliability of Primary Basins – Due to its age, basins have
corroded internal mechanism issues, and Basin D, E, H, I, and N
are not currently operational. With wet weather officially begins in
October 15th, at least two basins need to be back in service,
bringing the total available to 11 basins. With existing A-Side basins
being demolished and replaced with new basins, B/ C side of basins
need to be stay reliable for 10 years to support P2-98A
construction.
Basins D, E, H, and I are down for repair through P2-98B B & C Side Interim
Repair. Basin N is down due to the imbalance of the sweep arm. Basin N is
scheduled to be assessed by OEM of internal mechanism to identify addition
scope needed to put the basin back in service.
MP-692 P2 Primary Basin N Repairs is in place to cover additional items
beyond P2-98B scope.
P2-98A and P2-133 are in place to provide long term solutions to all A, B, & C
side of primary clarifiers.
Reliability of Waste Sidestream Pump Station C – Waste
sidestream pumps and their associate equipment show accelerated
corrosion issue due to the drains from the South Scrubber Complex.
The South Scrubber Complex uses bleach for their scrubbers and
the bleach pumps are oversized and do not have good turndown
ratio. Excessive bleach goes to the drains that go to the WSSPS-C.
The materials are not compatible with bleach, resulting accelerated
corrosion.
MP-420 Plant No. 2 South Scrubber Complex Bleach Pump is in place to
replace oversized bleach pump with smaller sized pump with better turndown
capacity. This will reduce excess bleach that flows to the WSSPS-C.
Two failed pumps (5HP and 35HP) are sent out for root cause failure analysis
and will be replaced with improved design.
X-054 WSSPS-C Rehabilitation at Plant No. 2 is in place to address corroded
equipment caused by replacing equipment with upgraded material.

Key Issues
Key Issues Actions and Recommendations
Reliability of EPSA Pumps – With J-117B rehabilitating OOBS pumps, up to 2 OOBS pumps
may be down during the construction, which is scheduled to begin in April of 2021. By then,
EPSA system needs to stay reliable to compensate outfall capacity loss from OOBS being
down. There are currently 3 ongoing projects to improve EPSA reliability, which are VFD cells
refurbishment, motor cooling improvement, and EPSA discharge line assessment and repair
EPSA motors cooling issue has been approved by Clearinghouse (PRN-00519) by modifying the motor cooling with
additional internal fans. This effort will be executed by the Small Capital Delivery group.
VFD cells refurbishment and control modernization approved by the Board. Plan is to complete the refurbishment
and perform control upgrades by summer of 2020.
Issued a Purchase Order to perform a confined space entry assessment for EPSA discharge pipelines. Once the
internal condition is known, repair plan will be developed.
OOBS & EPSA Overflow pipe and wing wall assessment – J-117A Interplant Effluent
Pipeline Rehabilitation assessed OOBS overflow structure pipe segments and its concrete wing
wall. The assessment identified separation of the pipe joints and deterioration of the wing wall
PS17-10 Emergency Overflow Weirs, Wing Wall Structural and Geotechnical Investigations is in place to investigate
the root causes of the issues and provide recommendations to protect these structures. This study will feed into a
FE project for execution.
Long Ocean Outfall Assessment – With long outfall pipe approaching 50 years in service,
need an extensive assessment to understand maintenance required to extend the useful life.
The permit with the California State Lands Commission was renewed for 25 years effective
August 28, 2017, and the permit requires to maintain the outfall to use its land.
PS18-09 Ocean Outfall Condition Assessment and Scoping Study is in place to determine the condition of ocean
outfall and provide recommendations to extend its useful life.
X-053 is created to execute rehabilitation efforts per recommendations from PS18-09. May need to assume similar
condition to that of the 78” Outfall to address its condition.
Corrosion issues – Due to its corrosive environment, there are various areas that began to
show signs of coating failure. There are areas, such as EPSA discharge line, that need to be
assessed and Surge Tower welding joint between lower concrete and upper steel shell
Continue to work with coating team to address visible coating failures. PRN-00480 will repair the OOBS pipeline
thermal expansion supports, and PRN-00566 will repair the external coating for OOBS & EPSA pipes
Coordinate with condition assessment team to develop work plans for welding joint and EPSA underground
discharge assessment.

ASSET MANAGEMENT SYSTEM SUMMARY – COLLECTION SYSTEM – PUMP STATIONS
Key Issues Actions and Recommendations
Safety – Currently four of OCSD’s older pump stations do not have atmospheric
monitoring (for hydrogen sulfide gases) or standard safety indication lighting.
Also, pump station infrastructure is often located in the public right of way making
safe access to these facilities an on-going issue.
A planning study has been established to review and interpret electrical code and
establish OCSD design standards to address this issue. Practicing on-going safety
measures and traffic control when working in the public right of way will continue to be
of the utmost importance.
Natural Phenomenon – Edinger pump station is located immediately adjacent to
an undersized flood control channel. Crystal Cove pump station is experiencing
gradual site settlement. Both natural hazards present a risk to normal operation
of the pump stations.
Siting analysis has identified an area farther away from the active flood control channel
to which Edinger pump station may be moved. Also, the County of Orange is planning
to increase the capacity of the channel to accommodate future planned flows. A
planning study has been established to determine the necessary mitigation measures
to remediate site settlement at Crystal Cove pump station.
Increased Methane Gas Levels – methane gas accumulation has become a
safety concern at some pump stations. The amount of gas seems to increase
during summer months and presents a unique challenge because of the short
response time necessary to address the safety concerns of increased ignition
risk.
OCSD crews respond to alarms that indicate increased levels of methane gas. An
internal effort has been defined to place flow monitors in the system to collect
necessary data prior to establishing a planning study to determine the cause of the gas
accumulation and possible mitigation measures.
Corrosion – Corrosion is an on-going problem in this very harsh environment. In
places were the system has been kept from venting and mixing of wastewater is
prevalent, such as wet wells, the degree of corrosion has (or will soon) require
the replacement/rehabilitation of the assets.
Visual assessments of known corrosion issues are performed on an on-going basis.
When necessary, cameras are used to evaluate the spreading of corrosion impacts and
confined space entry may be performed to gather additional information to determine
when the facility needs to be rehabilitated.
Groundwater Intrusion – Groundwater has penetrated four of the newly
constructed pump stations in the coastal region of the service area. Groundwater
is notoriously corrosive and may compromise the strength of the rebar within the
concrete structure walls.
Execute a planning study to identify possible mitigation measures.
Maintenance Access – In some cases, such as venting of the Newport Beach
force main system, access to critical facilities is limited by safety and public
impact concerns. In other cases, such as MacArthur Pump Station force main,
access to critical facilities is not possible because redundancy was not
considered when the pump station was designed.
OCSD continues to improve planned maintenance processes and inter-agency
coordination that allow crews to minimize impacts to the community during necessary
maintenance operations. A future capital project has been established to construct a
redundant force main to serve MacArthur pump station.

Key Issues
Key Issues Actions & Recommendations
Condition Assessment of Gravity Pipelines - Many factors impact the accuracy of the coding system used to
identify the type and severity of condition issues within the collection system. Video quality, operator experience,
and field conditions often make correct and consistent coding of defects difficult. For this reason, defects that have
been identified may not illicit an immediate response.
OCSD staff reviews condition reports on a regular basis and if necessary, marks the defect for monitoring or repair.
Condition Assessment of Siphons and Large Diameter Pipelines – Siphons are regularly cleaned but are not
inspected because they are inaccessible using CCTV equipment. Large diameter pipe (> 42”) are not cleaned and
CCTV footage does not identify sediment or debris below the waterline.
Develop and execute a Planning Study to identify alternative methods for inspection of siphons and large diameter
pipelines.
Capacity – The Collections Capacity Evaluation Study completed in 2019 conducted a detailed capacity analysis to
identify the location of capacity deficiencies during dry and peak wet weather flows.
Develop and complete CIPs identified by the Collections Capacity Evaluation Study to address capacity issues.
Monitor potential spill locations associated with capacity deficiencies not identified as near-term CIPs.
T-lock – The T-Lock PVC sheet lining system use to line manholes and concrete structures throughout the collection
system will be discontinued.
OCSD staff will investigate alternative liner technologies and methods to repair existing lined structures.

ASSET MANAGEMENT SYSTEM SUMMARY – COLLECTION SYSTEM – BUSHARD TRUNK
Key Issues
Key Issues Actions & Recommendations
Bushard Diversion Box - the Bushard Diversion Box is not able to operate as originally intended (flow modulation
between Plant No. 1 and Plant No. 2 based on flows).
A planning study is underway to determine a course of action regarding potential modifications to the Bushard
Diversion Box. This study will also incorporate box rehabilitation beyond the scope of the more immediate repairs
being performed as part of MP-307.
Condition Assessment of Gravity Pipelines - Many factors impact the accuracy of the coding system used to
identify the type and severity of condition issues within the collection system. Video quality, operator experience,
and field conditions often make correct and consistent coding of defects difficult. For this reason, defects that have
been identified may not illicit an immediate response.
OCSD staff reviews condition reports on a regular basis and if necessary, marks the defect for monitoring or repair.
Condition Assessment of Siphons and Large Diameter Pipelines – Siphons are regularly cleaned but are not
inspected because they are inaccessible using CCTV equipment. Large diameter pipe (> 42”) are not cleaned and
CCTV footage does not identify sediment or debris below the waterline.
Develop and execute a Planning Study to identify alternative methods for inspection of siphons and large diameter
pipelines.
Capacity – The Collections Capacity Evaluation Study completed in 2019 conducted a detailed capacity analysis to
identify the location of capacity deficiencies during dry and peak wet weather flows.
Develop and complete CIPs identified by the Collections Capacity Evaluation Study to address capacity issues.
Monitor potential spill locations associated with capacity deficiencies not identified as near-term CIPs.

Key Issues
Key Issues Actions & Recommendations
Tuberculation – Some portions of the existing metal pipes have tuberculation which poses a risk. Several of these
segments have been lined; however, some work remains to complete these repairs.
Review condition of unlined metal pipes and rehabilitate pipes subject to tuberculation as needed.
Local Sewers – A portion of gravity collection system that was local service was transferred to Newport Beach. None.
Condition Assessment of Gravity Pipelines - Many factors impact the accuracy of the coding system used to
identify the type and severity of condition issues within the collection system. Video quality, operator experience,
and field conditions often make correct and consistent coding of defects difficult. For this reason, defects that have
been identified may not illicit an immediate response.
OCSD staff reviews condition reports on a regular basis and if necessary, marks the defect for monitoring or repair.
Condition Assessment of Siphons and Large Diameter Pipelines – Siphons are regularly cleaned but are not
inspected because they are inaccessible using CCTV equipment. Large diameter pipe (> 42”) are not cleaned and
CCTV footage does not identify sediment or debris below the waterline.
Develop and execute a Planning Study to identify alternative methods for inspection of siphons and large diameter
pipelines.
Capacity – The Collections Capacity Evaluation Study completed in 2019 conducted a detailed capacity analysis to
identify the location of capacity deficiencies during dry and peak wet weather flows.
Develop and complete CIPs identified by the Collections Capacity Evaluation Study to address capacity issues.
Monitor potential spill locations associated with capacity deficiencies not identified as near-term CIPs.
T-lock – The T-Lock PVC sheet lining system use to line manholes and concrete structures throughout the collection
system will be discontinued.
OCSD staff will investigate alternative liner technologies and methods to repair existing lined structures.

Key Issues Actions & Recommendations
Unlined Reinforced Concrete Pipelines – The lower portions of the Santa Ana trunk are unlined reinforced
concrete pipe that has been routinely evaluated and is currently in acceptable condition. These segments are more
prone to corrosion related issues than typical pipe materials utilized within the collection system.
Continue frequent monitoring of the pipeline condition to provide routine updates from which the scheduling of a
future rehabilitation project (X-076) can be determined.
Sewer Transfer – Approximately 7.8 miles of gravity sewer were transferred to the City of Santa Ana. None.

CHAPTER 6 PROGRAM MONITORING AND IMPROVEMENTS
6.1 Program Monitoring
OCSD is continually evaluating AM Program progress and realized benefits. To support the
evaluation, OCSD is in the early stages (first year) of developing metrics for monitoring. The
metrics will be included in subsequent AMP versions.
6.2 AM Program Improvement Opportunities
Several improvement opportunities are defined in Table 6.1 as part of the AM Program
continuous improvement process. Reasonable timeframes are defined for implementing these
improvements. Future AMP updates will summarize the implementation progress.

CHAPTER 7 BUDGETARY CONSIDERATIONS
The AMP focuses on documenting short- to long-term planning of maintenance and capital
improvement projects to support effective budget development and sustainable operations.
OCSD has been striving to more accurately identify medium- to long-term capital cash flow
requirements. Specifically, the Planning Division has been working on developing a 20-year CIP
by creating project plans for forecasted rehabilitation, replacement, improvements and
expansion for the collection system and treatment plants. The CIP budget is being evaluated
and updated on an on-going basis as new information becomes available.
7.1 Capital Improvement Expenditures
Fiscal Year 2019-2020 Budget Update, adopted on June 26, 2019, includes updates to the 20-
year CIP outlay. Figure 7.1 shows the 20-year CIP outlay which includes current and projected
future Capital Improvement Program projects. Fiscal Year 2019-2020 CIP outlay is further
divided into process categories shown in Figure 7.2.

7.2 Maintenance Expenditures
7.2.1 Five-Year Historical Maintenance Expenditures
Figure 7.3 and Figure 7.4 show the historical actual spent versus budgeted operational and
maintenance expenditures for the treatment plants and collection system, respectively.
The treatment plant expenditures include maintenance services and materials (budget
objects 54010, 54020).
The collection system expenditures include maintenance services and materials (budget
objects 54010, 54020).
These costs represent the operations and maintenance costs of fixed assets, including
operationally funded repair/replacement projects.
Figure 7.3. Five-Year Historical Maintenance Costs for Treatment Plants
Figure 7.4. Five-Year Historical Maintenance Costs for Collection System
136
7.2.2 Three-Year Look-Ahead Maintenance Expenditures
Table 7.1 shows operational-funded projects identified to-date and includes the projected
annual expenditures. The projects are grouped by location (Plant No. 1, Plant No. 2, and
Collection System), and then sorted by the project start fiscal year and estimated cost (highest
to lowest). The list encompasses projects identified thus far. It is likely FY20-21 and beyond will
fluctuate based on the condition of assets as they age. Additionally, projects in the following list
represent expenditures that are operationally funded and capital in nature.

The District has a variety of revenue sources available for operating and capital expenses.
The major revenue sources are as follows:
• General Sewer Service Fees
• Industrial Waste Permit User Fees
• Capital Facilities Capacity Charges (CFCC)
• Property Taxes
• Interest Earnings
• Other Miscellaneous Revenue
• Debt Proceeds
2020-21 2021-22
General Service Fees –
User fees are ongoing fees for service paid by customers
connected to the sewer system. A property owner, or user, does
not pay user fees until connected to the sewer system and
receiving services. Once connected, a user is responsible for his
share of the system’s costs, both fixed and variable, in proportion
to his demand on the system. These fees are for both Single
Family Residences (SFR) and Multiple Family Residences
(MFR).
FY 2020-21 is the third year of the most recent five-year sewer
service fee rate schedule approved by the Board. The SFR rate
(the underlying basis for all sewer rates) will increase by 1.2
percent ($4) in each year of the two-year budget to $343 in FY
2020-21 and to $347 in FY 2021-22. These rates are still well
below the average annual sewer rate currently being charged
throughout the state.
$302.8M $307.5M
2
2020-21 2021-22
Industrial Waste Permit User Fees –
Fees paid by large industrial and commercial properties owners
connected to the sewer system. These fees are for the owner’s
share of the system’s costs, both fixed and variable, in proportion
to his demand on the system.
Since the inception of the Permit User Fee program in 1970,
users of the District’s system that discharge high volumes or high
strength wastewater are required to obtain a discharge permit
and pay for the full cost of service.
$10.0M $10.2M
Capital Facilities Capacity Charges (CFCC) –
Capital Facilities Capacity Charge is a one-time, non-
discriminatory charge imposed at the time a building or structure
is newly connected to the District’s system, directly or indirectly,
or an existing structure or category of use is expanded or
increased. This charge pays for District facilities in existence at
the time the charge is imposed, or to pay for new facilities to be
constructed in the future, that are of benefit to the property being
charged.
$18.6M $18.7M
Property Taxes –
The County is permitted by State law (Proposition 13) to levy
taxes at 1% of full market value (at time of purchase) and can
increase the assessed value no more than 2% per year. The
District receives a share of the basic levy proportionate to what
was received in the 1976 to 1978 period less $3.5 million, the
amount that represents the State’s permanent annual diversion
from special districts to school districts that began in 1992-93.
The District’s share of this revenue is dedicated for the payment
of debt service.
$99.0M $101.7M
Interest Earnings –
Interest earnings are generated from the investment of
accumulated reserves consisting of a cash flow/contingency, a
capital improvement, a renewal/replacement, and a self-
insurance reserve.
$6.4M $6.5M
Other Revenue –
Other revenue includes solids handling and capital assessments
from the Irvine Ranch Water District (IRWD); and O&M sewer
services provided to IRWD, the Santa Ana Watershed Protection
Authority (SAWPA), and the Sunset Beach Sanitary District.
$48.0M $50.2M
3
2020-21 2021-22
Debt Proceeds –
Certificates of Participation (COPs) are the District’s primary
mechanism for financing capital projects. COPs are repayment
obligations based on a lease or installment sale agreement.
COPs are viewed by the State of California as a share in an
installment arrangement where the District serves as the
purchaser. No new debt issuances are projected in the near-
term.
$0.0M $0.0M
Financing
If is necessary that the District utilize debt financing to meet its total obligations and to meet
projected construction schedules, the District uses long-term borrowing (Certificates of
Participation (COP)) for capital improvements that cannot be financed from current revenue.
Before any new debt is issued, the impact of debt service payments on total annual fixed costs is
analyzed. No new debt issuance is currently being planned.
The District Maintains its AAA Rating
The District maintains ratings of “AAA” from Standards and Poor and “AA” from Fitch. A triple A
rating is the highest obtainable for any governmental agency. In order to maintain this rating, the
District adheres to its 2001 Debt Policy and coverage ratios requirements. This Board-adopted
policy serves as the agency’s guide in the management of existing debt and in the issuance of
future debt.
OCSD Has Contractual Covenants
The District has contractual covenants within the existing COP agreements which require
minimum coverage ratios of 1.25. The minimum coverage ratio is the ratio of net annual revenues
available for debt service requirements to total annual debt service requirements for all senior lien
COP debt. The coverage ratio for senior lien COP debt was approved at 3.67 for FY 2019-20.
Orange County Sanitation District
Reserve Summary - FY 2019-20
Orange County Sanitation District (OCSD) has a Board of Directors Reserve Policy that sets forth seven criteria to
be used to determine its reserve level. As part of the OCSD financial and operating process, we have developed a
Reserve Policy which governs the establishment of our reserve level and the use of those funds. To ensure an
adequate and diverse reserve policy, we have established seven different criteria. These are not seven different
reserves, but seven criteria used to set the total reserve level. Reserves can only be used with the approval of
the Board of Directors. Below is a brief summary of the OCSD Reserve Criteria.
Reserve Policy Summary
Non-Discretionary
1) Debt Covenants and Other Requirements – Required by OCSD bondholders – $94 million – RESTRICTED
This level is set by various bond covenants. As OCSD issues debt, it is required to maintain certain levels
of reserves held specifically for repayment of that debt and cannot be reduced or used prior to repayment
of all outstanding debt issuances.
2) “Dry Period” – Property Tax Payments – 50% of Operating Costs – $84 million
The largest portion of OCSD revenues are user fees, approximately $300 million. These fees are listed on
and collected through the County property tax bill. Since we receive payments twice each year, we hold
funds in reserve specifically to pay operating expenses pending receipt of those payments.
3) “Dry Period” – Property Tax Payments – 100% of August Debt Service Costs – $77 million
The largest portion of OCSD revenues are user fees, approximately $300 million. These fees are listed on
and collected through the County property tax bill. Since we receive payments twice each year, we hold
funds in reserve specifically to pay debt service pending the receipt of those payments.
Discretionary
4) Operating Budget – 10% of the total Operating Budget as a Contingency – $17 million
We hold ten percent of our operating budget as an operating contingency for non-recurring and
unanticipated expenditures.
5) Capital Improvement Budget – 50% of the average 10-year CIP Program – $137 million
OCSD currently has a ten-year, $2 billion Capital Improvement effort. We hold the equivalent of 5% of
that total as a contingency specifically related to these Capital Improvement Program efforts.
6) Rehabilitation and Refurbishment – $64 million
In 2002, OCSD established a reserve level related to rehabilitation efforts at $50 million based on the
rehabilitation or replacement costs at that time. Although the total costs for rehabilitation or replacement
has increased substantially since 2002 as a result of the move to Full Secondary Treatment and the
Construction of GWRS, this reserve guideline has only been increases 2% annually, making it potentially
under-funded.
7) Catastrophic loss / Self-insurance – $57 million
OCSD is Self-Insured for Catastrophic Loss. $57 million of the District’s total reserves are related to holding
funds for this category. Although OCSD now has more than $10 billion in asset replacement value, this
level has not been increased since its establishment more than 10 years ago, making it potentially under-
funded.
Current 2019-20 Reserve Policy Requirement $530 million

OVERVIEW OF PROPERTY - LIABILITY INSURANCE
GENERAL MANAGER'S RECOMMENDATION
RECOMMENDATION:
Information Item.
BACKGROUND
Staff will provide an informational presentation on the Orange County Sanitation District’s (Sanitation
District)major insurance policies.The process of renewal begins each January,and final quotes are
typically received in June, shortly before the beginning of the new fiscal year.
The Sanitation District’s budget provides funds for the renewal of the following four (4)major
insurances for Sanitation District operations:
1)Excess General Liability Insurance
The Sanitation District’s Excess General Liability Insurance Program is currently provided
through the California Municipal Excess Liability Program (CAMEL)and its sister program,the
Alliant National Municipal Liability Program (ANML).The Sanitation District has participated in
the CAMEL program since FY 1996-97.
This program currently provides the Sanitation District with a $40 million dollar policy of
comprehensive coverage for municipal liability,bodily injury and property damage,and
personal injury.The program was structured to also include Employment Practices and Public
Officials Errors &Omissions coverage.The $40 million dollar coverage has a self-insured
deductible of $500,000.Since 1997,the Employment Practices portion of coverage has been
enhanced from a $2 million dollar sub-limit to the full policy limit of $40 million dollars.
2)Excess Workers’ Compensation
The Excess Workers’Compensation insurance coverage is with the California State
Association of Counties Excess Insurance Authority (CSAC EIA).The Sanitation District has
participated in this program or its predecessor since 2003.The Excess Workers’
Compensation program currently provides “Statutory”(unlimited)coverage with a self-insured
retention (SIR),or deductible,of $1 million dollars.The use of Excess Workers’

retention (SIR),or deductible,of $1 million dollars.The use of Excess Workers’
Compensation Insurance dates back to the late 1980’s.
3)All-Risk Property and Flood Insurance (Includes Boiler & Machinery Insurance)
The All-Risk Property and Flood Insurance Program (Property Insurance)provides
comprehensive coverage for much of the Sanitation District’s real and personal property
regarding virtually all perils including fire, flood, and business interruption.
Current Property Insurance limits are $1 billion dollars for most perils other than flood and
earthquakes,and $300 million dollars for flood,with many sub-limits for various situations.In
order to reach $1 billion dollars in limits,the broker had to arrange for more than a dozen
different insurers. The SIR is $250,000 per occurrence for most types of losses.
Since the late 1990’s,the Property Insurance has been with a nationwide joint purchase
property insurance program called Public Entity Property Insurance Program (PEPIP),one of
the world’s largest property programs.It is important to note that this joint purchase property
insurance program offers the purchasing power of numerous large public entities without the
pooling or sharing of coverage or losses.
The Boiler &Machinery Insurance Program,part of the property insurance,provides
comprehensive coverage for loss caused by machinery breakdown and explosion of steam
boilers or other covered process equipment,including damage to the equipment itself and
damage to other property caused by covered accidents.The current Boiler &Machinery
Insurance Program provides coverage of $100 million dollars per occurrence with deductibles
ranging from $25,000 to $350,000 for losses caused by covered machinery breakdown (e.g.,
motors,steam turbines,digesters,co-gen engines).Damages to the equipment,as well as
damages to other property and improvements caused by the machinery breakdown,are
covered by the Boiler &Machinery Insurance.This program augments the Sanitation District’s
All-Risk Property Insurance that covers perils such as fire and flood.
4)Earthquake Insurance
The Sanitation District previously carried earthquake insurance as part of its Property
Insurance,but in the last 15 years earthquake insurance proved difficult to obtain or not cost-
effective.The Sanitation District asked its insurance broker each year to survey the market to
see if rates have changed.Finally,in 2015 a plan was created to insure several key Sanitation
District structures identified by Engineering,thus keeping the cost in line.The insurance is a
high deductible plan with a limit of $25 million dollars in total.
