Monster, pictured in Figures 1 and 2. JWC has
developed Wipes Ready technology which supposedly
improves the ability to cut long-fiber materials, such as handy-wipes and towels, into smaller pieces to prevent
pump ragging. Both units have dual rotating cutter
stacks, constructed of heat-treated alloy steel for
corrosion protection, that pull solids into the stack for shredding. The cutters have 17 teeth each and are
serrated for improved wipes shredding. Each operates
with a 5 horsepower immiscible motor, able to withstand temporary overflow conditions in the event of grinder
failure. A stainless steel overflow bar rack provides a backup for debris removal in the event of a grinder
failure. The Channel Monster has an additional rotating perforated screening drum that directs debris into the
cutter stack, while maintaining the flow. The Buena
Creek Pump Station currently has two Channel monsters
installed and has operated well with this configuration.

The Franklin Miller (FM) Taskmaster Grinder Model TM8532, Figure 3, is an alternative that is similar to the JWC Muffin Monster. The main difference between the Franklin Miller and JWC models is the configuration of the cutter stacks. While JWC cutters are machined as individual disks mounted with spacers in between, Franklin Miller machines a cutter cartridge from a solid block of alloy steel; a typical cutter cartridge replaces 6 cutters and 6 spacers. Each cutter has 11 teeth. The FM Taskmaster operates with a submersible 3 horsepower motor, capable of running fully submerged or in air.

All three units are suitable for RWPS, but there are several factors to be considered. The inclusion of the perforated drum on the Channel Monster allows for better flow through the unit when it is not operational, but additional moving parts increase the potential for maintenance and repair issues. The Channel Monster has the largest footprint of the three units, taking up a larger area in the channel than the other units, which could impact hydraulics and increase the depth of flow in the upstream pipes.

Under normal conditions, most of the cutter stack will be submerged, with the majority of cutter teeth engaged. It is also twice as heavy as the other models, which would make removal/maintenance more difficult. JWC recommends inspecting the cutter stack on all models twice yearly for signs of wear that may require tightening. Franklin Miller claims that the cutter stack in the Taskmaster never needs retightening, as the solid block cutter cartridge replaces multiple moving parts which are more likely to loosen. Both JWC units have more teeth per cutter than the FM unit, providing more points of contact for pulling debris into the cutters. The Muffin Monster and FM Taskmaster both have a smaller footprint than the Channel Monster, but the cutter stack is taller and will remain partially above the flow, so a lower percentage of cutter teeth will come into contact with the flow. Specifications for all three units are summarized in Table 1.

CONCLUSION AND RECOMMENDATION
While the Franklin Miller Taskmaster and both JWC Environmental sewage grinders are able to meet the needs of RWPS, the JWC Environmental 30005 Muffin Monster is the most cost efficient alternative. Consideration must also be given to the preference of the pump station operations staff. Concerns about JWC Environmental's customer service and slow response time were discussed, and a request was made to investigate the options available from Franklin Miller. The FM grinder that suits the application at RWPS is also the most costly alternative. At this time, no decision has been made about sole sourcing.

Subject: Raceway Pump Station - Deragger Update
Dear Mr. Alex:

The purpose of this report is to share the information collected on Clearwater Controls Deragger II, for possible inclusion in the final design for the rehabilitation of the Raceway Pump Station (RWPS).

BACKGROUND
The City of Vista (City) owns four wastewater pump stations - the Buena Creek Pump Station (BCPS), the Buena Vista Pump Station (BVPS), and the Raceway Pump Station (RWPS) and the Aqua Hedonda Pump Station. All three pump stations convey raw wastewater to the Encina Water Pollution Control Facility. The accumulation of rags and debris on pump impellers is a common problem in wastewater collection systems. As rags build up it can cause significant damage to the pumps, pump motors and variable frequency drives (VFD). One common means to prevent the rag build up is to install grinders upstream of lift stations. Grinders break down rags and large debris into smaller fragments that cannot get caught up in the pump impeller.

Grinders are installed at all of the City's lift stations. At the RWPS, the grinder has recently been out of service, allowing rags into the wet well. The rag build up on the pump impellers became significant enough that it resulted in a pump failure. Ultimately, the pump VFD was so badly damaged that replacement was required.

Another means to prevent ragging has recently been introduced to the wastewater market in the United States. The Clearwater Controls Deragger utilizes pump controls to reverse the pump impeller when ragging is detected. The City recently came across the device and there is a desire to investigate the potential to use at the City's pump stations.

PRODUCT OVERVIEW
The Deragger II is an Anti-Ragging Device (ARD) that fits into the pump control panel or VFD panel and continuously monitors the pump. It prevents blockages by initiating cleaning cycles at every pump start up, at specified time intervals, and when analog input setpoints are breached.

The cleaning cycle is a series of forward, reverse, and stopping actions that clear the impeller of rags and fat deposits, and is customized to meet the needs of the site. Typical parameter setpoints used to trigger a cleaning cycle are high amperage, indicating that the motor is working harder than necessary, and low flow or increased wet well level, which both indicate problems with pump operation likely caused by ragging. The ARD sends a signal to the PLC when it begins a clean cycle; if there is a persistent blockage, the cleaning cycle will repeat, and if it isn't cleared and keeps repeating, this indicates that the pump needs to be dealt with 05/13/2025 C9 831 of 1078

manually. Additional features that can be added include a wet well clean cycle, batch and volume pumping, and dry run protection.

US INSTALLS AND REFERENCES
The Deragger II is a fairly new technology from Clearwater Controls in Scotland that has been in the United States for less than two years. While the Deragger II has seen broader use in the United Kingdom since its introduction in 2011, many US municipalities are either not aware of it or are hesitant to use it until it has a more proven track record. Ponton Industries, Inc., the local US distributor for Clearwater Controls, provided a list of five US installs and references to gather information on how the Deragger has affected operations. Contacts at all five locations (three of them in Southern California, and two in Florida) were interviewed, with basic information summarized in Table 1.

REFERENCE FEEDBACK
Los Angeles County Sanitation District (LACSD) was the first US location to use the Deragger II, installing it at the Western Avenue Pumping Station on a trial basis. The site had a prevalent ragging issue and one of the senior engineers had been investigating the possibility of reversing pumps to clear rags from the impellers when he came upon this device. Deragger II's were then installed on two 50 hp pumps, which previously required manual deragging about four times a month. During the trial, the Deragger II averaged one clean cycle per day, and no manual deragging was necessary. The trial results lead LACSD to integrate the Deragger II into the Long Beach Main facility, which handles about 35 MGD. The sites 200 hp pumps were having 05/13/2025 C9 832 of 1078

problems with ragging, requiring operators to perform manual cleaning and rag removal an average of 18 times per month, an unsanitary task that reduces productivity and presents a safety hazard. Since inclusion of the Deragger II, Mr. Pettit noted only one instance of manual deragging. When asked about any issues regarding installation, startup, and operation, the only problem mentioned was a small issue with the Modbus that hasn't affected performance.

Clearwater Controls has been very responsive to this and all aspects of the use of their product.

The remaining references cited similar results with the Deragger II.

CONCLUSION
Carollo has concerns about including this product in the design for RWPS. The install list provided by the local distributor list is very short, with most sites only having the Deragger II in service for 6 months or less. While two of the sites use the deragger with a VFD, none were found that are using this product with Allen-Bradley VFD's, as are in use at RWPS. The distributor mentioned that the Deragger II was ideal for locations without a grinder, and that it was preferable to have the debris travel through the facility intact where it could be removed from the process stream easily rather than having the shredded pieces clog up digesters downstream. Since RWPS typically operates with a grinder online, the pumps shouldn't experience the ragging issues that have occurred during the time that the Moyno grinder has been removed for maintenance. Furthermore, there are serious reservations about using this product with an existing pump from the standpoint that rotating the pump impeller backwards may be outside the capabilities of the pump, and could result in damage to the pump. A major drawback is that integrating this product into the design of the new VFD's would require the addition of two contactors; one for forward rotation and one for reverse. For this horsepower size, the contactors are of significant size, and given the very limited footprint that is available, it is not likely that the device can be integrated in the VFD panels without significantly rearranging the electrical gear layout.

RECOMMENDATION
Given the lack of long-term evaluation of this product, the issues regarding integration into the VFD's, and that ragging at RWPS is primarily resolved with the use of grinders, it is not recommended to install the device at the City's pump stations..

EXECUTIVE SUMMARY
ES.1. INTRODUCTION
Encina Wastewater Authority (EWA) is a public joint powers authority located in Carlsbad, California, that provides wastewater treatment services to approximately 400,000 North San Diego County residents and industrial customers. EWA is comprised of six member agencies consisting of the City of Carlsbad, City of Vista, City of Encinitas, Buena Sanitation District, Leucadia Wastewater District, and Vallecitos Water District.

EWA was formed to operate and administer the Encina Water Pollution Control Facility (EWPCF), which is a secondary activated sludge treatment faci lity, to treat wastewater from the six Owners.

Wastewater is conveyed to the EWPCF by several pump stations throughout the service area. EWA operates and maintains four pump stations for the Cit ies of Carlsbad and Vista: Buena Creek Pump Station (BCPS), Raceway Basin Pump Station (RBPS), Buena Vista Pump Station (BVPS), and Agua Hedionda Lift Station (AHLS). Secondary effluent from the EWPCF is sent to the Carlsbad Water Recycling Facility (CWRF) for additional treatment to produce Title 22 recycled water for use by the Carlsbad Municipal Water Di strict (CMWD). The BCPS, RBPS, BVPS, AHLS, and CWRF are facilities that are owned by Carlsbad and/or Vista, and are operated and maintained by EWA, and are designated “remote facilities” as they are not located at the EWPCF.

EWA aims to maintain reliable and cost-effective resilient service by implementing proactive asset management approaches. In addition, EWA’sobjective is to invest appropriately to fully fund the cost of service, including capital improvements by estab lishing a well-grounded Asset Management Planning Services. The Remote Com prehensive Asset Management Plan ( R-CAMP) serves as a primary planning tool utilized to cost effectiv ely manage assets by planning, prioritizing, and scheduling condition assessments efforts and asset rehabilitation and replacement (R&R) for facilities operated by EWA, including the BCPS, RBPS, BVPS, AHLS, and CWRF.

The Memorandum of Understanding (MOU) between Owners and EWA as operators and maintainers requires EWA to develop the capital acquisiti on budget for each facility, as well as make recommendations for larger projects for Owners to incorporate into their CIPs. The R-CAMP identifies future expenditures for those cap ital acquisition budgets for mainten ance projects and conceptually identifies EWA staff recommendations for capita l improvement projects (CIP), which the respective facility Owner can then incorporate into their CI P for the facilities, including Owner’s review of capacity and upgrades. The R-CAMP then functions as a communication tool for the proposed improvements to the Owners, their re presentatives, and EWA staff. This R-CAMP update includes recommendations for capital acquisition budget and CIP recommendations for Owners to incorporate for fiscal year (FY) 2023 through FY2028. Capital ass ets related to projects for EWA’s EWPCF are identified in the Encina Comprehensive Asset Management Plan (E-CAMP) and are not evaluated in this R-CAMP.

FY2023 R-CAMP Report

ES-2

While the R-CAMP is updated every two years and is i ndependent of the budgeting process, the information is leveraged during the budgeting process to provide direction for EWA staff and Owners.

EWA staff focus on the capital acquisiti on budgets, while Owners incorporate the CIP recommendations into their own CIP plans for the facilities for capacity and other upgrades.

ES.2. R-CAMP PROCESS
The R-CAMP process includes five task elements: proj ect identification and grouping; project evaluation; project cost estimating; project prior itization; and implementation schedule. EWA engaged the Owners through a series of workshops to review each key step in the process. A flow diagram of the EWA CIP development, including the R-CAMP process, is provided as Figure ES-1 with the R-CAMP task elements shown in blue-green.

FY2023 R-CAMP Report

ES-4

Projects that are included in the R-CAMP are identified through a number of means including EWA’s Computerized Maintenance Management System (CMMS), field condition assessments, site visit, the previous R-CAMP update, EWA or Owner staff, studies, report s, and other engineering services performed for EWA or the Owners. Projects may be grouped based on proximity, type of work, or priority to increase economic efficiency and reduce costs.

After the final list of R-CAMP projects is established, EWA and the Owners worked together to assign each project to the responsibility of EWA or the Owners. Generally, smaller maintenance projects are assigned to EWA and larger capita l projects are assigned to the Ow ners. Each project is evaluated using a set of six evaluation criteria: safety; regulat ory compliance; reliability; impacts to the public and EWA; energy efficiency; and organizational efficiency. These evaluation criteria are assigned a criticality factor that represents the level of importance of each across all the projects. Each project is scored across each of the evaluation criteria and th e sum of the six criteria scores is the evaluation score for each project.

Project cost estimates are developed for the full list of projects in the R-CAMP. All capital acquisition projects assigned to EWA in the R-CAMP are prioritized by considering the evaluation scoring results and estimated costs. The project prioritization process provides EWA with informed condition and cost data to select which projects to schedule for implementation over the next six fiscal years (through FY2028). Recommended priorities are also provided for the Owner projects for the Owner’s consideration. A recommended implementation sc hedule is prepared and provides direction for upcoming improvements to be included in the budgeti ng process. Projects that are not selected for implementation over the next six fiscal years are not scheduled in the R-CAMP but are included for future reference.

ES.3. CONDITION ASSESSMENT SUMMARY
Condition assessments are a key component of a strong asset management program. The benefit to a utility of a quantitative condition assessment is to capture both the estimated timing of asset failure and the impact such failures would have on broa der operations. The condition assessment program allows EWA and Owners to devel op more informed asset manage ment plans and capital budget prioritization processes. In addition to the condition assessments that are conducted regularly by EWA or are triggered by asset age or staff observations, Hazen performed a combination of field condition assessment and focused condition assessment. F or the BCPS, RBPS, and BVPS a comprehensive condition assessment was performed in May 2021 followed by a site visit in October 2021, while for CWRF the focused condition assessment approach was used. Given that AHLS has recently undergone construction and significant rehabilitation effort, a site visit was performed for this remote facility focused on performance and functionality issues, since most of the assets are in newer condition.

ES.4. STUDIES AND PROFESSIONAL SERVICES
Studies are completed to provide planning informa tion for maintaining remote facilities. Additional professional services include engineering services, research and development (R&D) services, permitting, and other services. A more detailed description of the id entified studies and professional services can be found in section 4 of this document.

ES.6. PROJECT EVALUATION
Projects in the R-CAMP are evaluated using a set of six evalu ation criteria. These evaluation criteria are assigned a criticality factor from 1 to 6, with 1 representing the lowest level of importance and 6 representing the highest. Table ES-2 provides the six evaluation criteria and their assigned criticality factors.

Table ES-2: Evaluation Criteria
Evaluation Criteria Criticality Factor
Safety 6
Regulatory Compliance 5
Reliability 4
Public and EWA Impacts 3
Energy Efficiency 2
Organizational Efficiency 1
Each project is assigned an impact factor across each of the six defi ned evaluation criteria from 0 to 5, with 0 representing the lowest impact and 5 re presenting the highest impact. The impact factors provide a relative comparison of each project’s ability to satisfy each of the defined evaluation criteria. 05/13/2025 C9 852 of 1078
FY2023 R-CAMP Report

ES-8

The impact factors assigned to a project for each evaluation criteria are then multiplied by the criticality factor of the evaluation criteria to calculate criteria scores. The six criteria scores are then summed to determine the evaluation score for each project.

ES.7. PROJECT PRIORITIZATION
Projects identified in the R-CAMP include those recommended for implementation in the next six fiscal years as well as other potential future pr ojects. Projects, studies , and professional services recommended for implementation over the next six fiscal years are considered prioritized projects and are identified in Table ES-3 through Table ES-7 along with a brief project description and evaluation score for each. A consequence of deferment for each project and study is al so provided in the table based on an impact factor of less than 3. The consequence of deferment represents the area of impact, across the evaluation criteria, where not implementing the project, study, or professional service would have a negative effect.

ES.8. RECOMMENDED PROJECT IMPLEMENTATION SCHEDULE AND

COST SUMMARY
The recommended project implementation schedule is based upon the project evaluation process and prioritized projects for projects in this R-CAMP. The capital acquisiti on budgets for EWA and recommended CIP projects for Owner projects over the next six years, FY2023 through FY2028, are summarized in Table ES-8. The R-CAMP identifies future expenditures for those capital acquisition budgets for maintenance projects and conceptually identifies EWA staff recommendations for capital improvement projects (CIP), which the respective facili ty Owner can then incorporate into their CIP for the facilities, including Owner’s review of capacity and upgrades.

In addition, subsequent R-CAMPs will monitor and re-evaluate proj ects in and beyond the six-year implementation schedule provided in this R-CAMP. Owners should incorporate R-CAMP recommendations for CIP, as well as Owner’s review of capacity and upgrades, and routinely review with their respective budget cycles. Common themes of these projects that should continue to be evaluated and considered include:

1. Rehabilitation and replacement of aging infrastructure

2. Facility expansion and coordinati on with Owner master planning efforts

3. Improvements to reduce impacts to the public and EWA (such as sound, appearance, and traffic)

4. Efficiency optimization

5. Future regulatory and industry trends

1. INTRODUCTION
Encina Wastewater Authority (EWA) is a public joint powers authority located in Carlsbad, California, that provides wastewater treatment services to approximately 400,000 North San Diego County residents and industrial customers. EWA is comprised of six member agencies consisting of the City of Carlsbad, City of Vista, City of Encinitas, Buena Sanitation District, Leucadia Wastewater District, and Vallecitos Water District.

1.1 BACKGROUND
EWA was formed to operate and administer the Encina Water Pollution Control Facility (EWPCF), which is a secondary c onventional activated sludge treatment facility, to treat wastewater from the six member agencies. Was tewater is conveyed to the EWPCF by several pump stations throughout the service area. EWA contract operates and maintains four pump stations and one wastewater treatment plant producing Title 22 disinfected tertiary recycled water.

Facilities include: Buena Vista Pump Stati on (BVPS), Raceway Basin Pump Station (RBPS), Buena Creek Pump Station (BCPS), and Agua He dionda Lift Station (AHLS), as well as the Carlsbad Water Recycling Facility (CWRF). Up to 7 MGD of secondary effluent from the EWPCF may be pumped to the Carlsbad Water Recycli ng Facility (CWRF) for additional treatment to produce Title 22 disinfected tertiary recycled water for use in the Carlsbad Municipal Water District (CMWD) service area. The BCPS, RBPS, BVPS, AHLS, and CWRF are facilities that are owned by Carlsbad and/or Vista, and are operate d and maintained by EWA. These facilities are designated as “remote facilities” as they are not located at the EWPCF.

Site addresses and a brief description of each remote facility are provided below:

1.1.5. Carlsbad Water Recycling Facility
The CWRF is owned by the Carlsbad Municipal Water District (CMWD), a district of the City of Carlsbad, and was constructed in 2005 and was most recently expanded in 2016. The Plant is located immediately to the south of the EWPCF. The rated capacity of the CWRF is 7 mgd. The CWRF treatment process includes granular media filters (GMF), microfiltration (MF), reverse osmosis (RO), ultrafiltration (UF), and disinfection through dosage of sodium hypochlorite. The MF and RO systems are not currently in service . The Equalization Basin at the CWRF is owned by EWA and provides a total of 8 million gallons of storage capacity through two compartments.

The west compartment is used primarily for re cycled water but can be used for secondary 05/13/2025 C9 863 of 1078

equalization in wet season, and the east compartm ent is intended for secondary equalization with the option to use it for recycled water during dry season if secondary equalization is not required.

The Plant began producing Title 22 recycled wate r in November 2005. During the first full year of operation, CMWD distributed 165 million gallons (512 acre-feet) of recycled water from the CWRF for use throughout the City of Carlsbad. From January 2021 to December 2021, the CMWD distributed 739.27 million gallons (1,881 acre-feet).

1.2 PURPOSE
EWA aims to maintain reliable and cost-effective resilient service by implementing proactive asset management approaches. In addition, EWA’s objective is to invest appropriately to fully fund the cost of service, including capital improveme nts by establishing a well-grounded Asset Management Planning Services. The Remote Comprehensive Asset Management Plan (R-CAMP) serves as a primary planning tool utilized to cost effectively manage assets by planning, prioritizing, and scheduling condition assessments efforts and asset rehabilitation and replacement (R&R) for facilities operated by EWA, including the BCPS, RBPS, BVPS, AHLS, and CWRF.

The R-CAMP serves as a planning tool used to cost effectively manage remote assets. The Owners have invested significant resources in the remote facilities, and EWA places a high importance on preserving asset reliability of the remote facilit ies while protecting the health and safety of its workers and the public. The focus of the majo rity of the projects identified in the R-CAMP are safety, regulatory compliance, reliability, publ ic and EWA impacts, energy or organizational related.

The purpose of the R-CAMP is to provide a comprehensive and reliable planning tool to successfully address infrastructure needs and challenges. The R-CAMP and related documentation has been developed to provide an updated assessment for major equipment and facilities. This allows EWA and Owners to plan ongoing assessment and replacement of assets while considering future expansion of the facilities. Capital assets related to EWA’s EWPCF are not evaluated in this R-CAMP as those are provided in the E-CAMP.

The R-CAMP provides a project implementation schedule and cost summary for the next six fiscal years (FY) (FY2023 through FY2028). While the R-CAMP is independent of the budgeting process, the information is leveraged during the budgeting process as well as providing direction for EWA and Owners staff. The MOU between Owne rs and EWA as operators and maintainers requires EWA to develop the capital acquisiti on budget for each facility, as well as make recommendations for larger projects for Owners to incorporate into their CIPs.

The R-CAMP identifies future expenditures for those capital acquisition budgets for maintenance projects and conceptually identifies EWA staff recommendations for capital improvement projects (CIP), which the respective facility Owner can th en incorporate into their CIP for the facilities, including Owner’s review of capacity and upgrades. The R-CAMP then functions as a communication tool for the proposed improvements to the Owners, their representatives, and EWA staff. Ultimately, the EWA Board of Directors, including the Owners’ Board Members,considers 05/13/2025 C9 864 of 1078

2. REMOTE COMPREHENSIVE ASEET MANAGEMENT PLAN

PROCESS
This section outlines EWA’s approach and basic framework behind the R-CAMP process, which parallels the E-CAMP process. The R-CAMP process incorporates project identification based on asset inventory and ongoing condition assessments. The R-CAMP helps establish capital rehabilitation project planning with considerati on given to anticipated changes in regulatory compliance, cost-saving opportunities, available funding, and ongoing operations and maintenance (O&M) requirements.

2.1. PROCESS
The R-CAMP process includes five primary task elements which are as follows:
x Task Element 1 – Project Identification and Grouping
x Task Element 2 – Project Evaluation
x Task Element 3 – Project Cost Estimating
x Task Element 4 – Project Prioritization
x Task Element 5 – Implementation Schedule
A flow diagram of the EWA CIP development, including the R-CAMP process and Asset Management process, is provided as Figure 2-1. The following subsections provide detail on the five R-CAMP process task elements listed above. As part of the R-CAMP process, projects are assigned to either EWA or Owners. Smaller maintenance projects are generally assigned to EWA, and larger capital projects are generally assigned to Owners, since there are some efforts that may be better suited to a particular lead agency. EWA and the Owners may use this information when developing their FY budgets.

FY2023 R-CAMP Report

2.1.1. Project Identification and Grouping
The first step of the R-CAMP process is identification and grouping of projects. Projects that are included in the R-CAMP are identified through a number of means including EWA’s Computerized Maintenance Management System (CMMS), condition assessments, probability of failure, risk, the previous R-CAMP, EWA or Owners staff, studies, reports, other engineering services performed for EWA or the Owners, re gulatory environment, and industry trends. The identified projects are reviewed and discusse d with EWA and Owners staff regarding their inclusion in the R-CAMP. This section will discuss the methods that are used to identify the projects.

2.1.2. Computerized Maintenance Management System
EWA manages its assets through the CMMS eMai nt by Fluke. The CMMS tracks assets for preventative maintenance activities which generall y repair or upgrade minor assets as well as major assets that are replaced or upgraded through capital projects. When the CMMS identifies an asset that is within approximately five years of the end of its nom inal service life, a condition assessment will be triggered.

EWA has recently incorporated asset management calculations such as remaining useful life analysis, risk assessment and cost estimating with in eMaint to streamline the projection of R&R based on the existing condition and other asset data. The work order process has also been updated to allow operations and maintenance staff to submit a condition score for the assets as they close the work orders. This allows EWA to make renewal decisions based on the latest condition of the assets rather than their age.

2.1.3. Condition Assessments
Condition assessments are a key component of a strong asset management program and provide a solid basis for future decision making by providing up-to-date information that is used to confirm the concerns that have been raised and identify ne w concerns and risks. Decisions leading to the R&R of assets rely on a clear unde rstanding of the condition of its i nfrastructure and how it is performing. Poor or missing asset condition informati on could result in the inability to identify a potential failure of an asset which can have consequences that constitute a business risk or potential loss. This would leave limited options which coul d require the asset to be replaced reactively instead of proactively, usually the more expe nsive option. By conducting regular comprehensive condition assessments and monitoring asset performance, rehabilitation strategies can be defined, and replacement schedules determined that can result in the lowest net-life capital and O&M costs.

This exercise allows EWA to better understand the remaining useful life of the assets, plan ongoing assessment efforts, update maintenance schedules
, updating total asset management costs and
funding needs, and more effectively manage assets. Capital expenditures can be prioritized by ranking asset replacement to maintain and replace th e assets which maximizes the service life at the lowest overall cost.

Hazen performed condition assessment on BCP S, RBPS and BVPS in May 2021 followed by observations during the site walk performed in October 2021. A condition assessment documents 05/13/2025 C9 868 of 1078
FY2023 R-CAMP Report

the current condition of the asset(s) being assessed and recommends one of the following when it is completed:

1. For assets with remaining useful life, the a ssessed service life can be extended assuming a cost-effective level of maintenance. The CMMS will be updated to reflect the new assessed service life.

2. For assets with a near-term end of useful life, a project is identified to replace or rehabilitate the asset. After the asset is replaced or rehabilitated, the CMMS will be updated to reflect the new asset information.

3. For assets with condition sc ore of Poor and Fair, a project is identified to perform a proper R&R action. Depending on the type of action (re placement or repair), the CMMS will be updated to reflect the new asset information including condition score.

2.1.4. Previous Remote Comprehenisive Asset Management Plan The previous R-CAMP (2021) was used as another source to identify projects to include in the R- CAMP currently being prepared. The previous R-CAMP includes a comprehensive list of projects and recommendations that were formerly identified for the remote facilities. This list, the outcome of subsequent budgeting cycles, and EWA i nput are used to identify which previous R-CAMP projects should be included. The following summarizes which projects from the previous R-CAMP are either included or not included in the current R-CAMP:

Included

1. Projects that were not selected for implementation in either the previous R-CAMP or through the budgeting process.

2. Projects that were selected for implementation in the previous R-CAMP but were only partially funded or were not completed or funded as recommended based on the budgeting process.

Not Included

1. Projects that were selected for implementation in the previous R-CAMP and were completed or funded as recommended based on the budgeting process.

2. Projects that were previously identified or recommended but not selected through the budgeting process that have since been classi fied as projects that should not be included. A project may be chosen to not be included for reasons such as the project may not meet cost/benefit requirements, or it has been determined it does not need to be completed.

2.1.5. Other Project Sources
In addition to the previous R-CAMP, CMMS, and recent condition assessments, other sources of information are sought, reviewed and evaluated for inclusion in the FY2023 R-CAMP. Projects to be included in the R-CAMP may be identified from the following:

1. EWA and Owners Staff – Staff observations of the operational performance and condition of an asset may trigger a Level 1 (Visual) condition assessment to be completed in advance of the CMMS triggering a condition assessment, which could result in the identification of a project. Additionally, EWA and Owners st aff are encouraged to provide input on potential process improvements that might require new assets.

2. Studies and Reports – Studies and reports are routinely completed including conceptual studies, special studies, and master plans. These studies and reports may recommend projects to be completed which could be incorporated into the R-CAMP including:
x Outstanding projects identified in FY2021 R-CAMP
x Fats, Oils, and Grease Mitigation Re commendation Technical Memorandum (2021)
x SCADA Migration Design Concept (2021)
x Carlsbad Recycled Water Quality (2020)

3. Engineering Services – Professional engineering service s are provided to EWA and the Owners on an ongoing basis. Through these serv ices, projects may be identified which could be incorporated into the R-CAMP.

4. Regulatory Environment – Changes to regulations or legislation may impact operations at the remote facilities. Based on these changes, projects may be identified which could be incorporated into the R-CAMP.

5. Industry Trends – Trends within the wastewater and water industry such as climate change, water reuse, and technology, may impact operations at the remote facilities. Projects may be identified based on these trends which could be incorporated into the R-CAMP.

2.1.6. Project Reference List
This R-CAMP includes projects for BCPS, RBPS, BVPS, and CWRF based on the Kennedy Jenks. (2020), FY 2021 Remote Comprehensive Asset Management Plan (R-CAMP) technical report and the new defined projects for AHLS that was under construction previously.

2.1.7. Project Grouping
Grouping of R-CAMP projects occurs after all projec ts to be included in the R-CAMP have been identified. Where practical, projects may be groupe d into a single project to increase economic efficiency and reduce costs. Projects can be group ed together based on several considerations including proximity of project locations, type of work, or priority of the projects to increase economic efficiency and reduce costs. After project grouping is completed, a final list of projects 05/13/2025 C9 870 of 1078
FY2023 R-CAMP Report
2-6
to be included in the R-CAMP is established. Each individual item in a project can be identified based on the source of information used (Staff, Condition Assessment, etc.) to include that item for R-CAMP projects. After the final list of R-CAMP projects is established, EWA and the Owners work together to assign each project to the responsibility of EW A or the Owners. Smaller maintenance projects are assigned to EWA and larger capital projects are assigned to Owners.

2.1.8. Project Numbering
Projects are given unique numbers for identific ation purposes. Condition assessments, studies, updates, engineering services and other services are also numbered in accordance with the project numbering system. The numbering system for projec ts assigned to EWA is different than the numbering system for projects assigned to Ow ners. The numbering system for EWA projects consists of three segments as described below and depicted in Figure 2-2 using P-38002-001 as an example while the numbering system for Owners projec ts consists of four segments as described below and depicted in Figure 2-3 using P-9.5.005 as an example. A summary of the project numbering system breakdown structure for Owne rs projects and how it relates to projects identified in the E-CAMP and R-CAMP is presented in Table 2-1.

2.1.9. Project Evaluation
After the final list of projec ts to be included in the R-CAMP is established, each project is individually evaluated by EWA a nd Owners staff using a set of six evaluation criteria: safety, regulatory compliance, reliability, impacts to the public and EWA, energy efficiency, and organizational efficiency. These evaluation criteria are assigned a criticality factor that represents the level of importance of each across all the projec ts. The criticality factors stay with their corresponding evaluation criteria throughout the project evaluation process.

Each project is assigned an impact factor acro ss each of the evaluation criteria which provides a relative comparison of each project’s ability to sa tisfy each of the criteria. The impact factors assigned to a project for each evaluation criteria are multiplied by the cr iticality factor of each evaluation criteria to develop criteria scores. The sum of these six criteria scores is the evaluation score for each project. The criteria score calculation is illustrated below, and the project evaluation process is discussed in further detail in Section 6 of this R-CAMP. ݎ݋ݐܿܽܨݐܿܽ݌݉ܫ

2.1.10. Project Cost Estimating
Project cost estimates are developed for th e final list of projects included in the R-CAMP. The estimates were reviewed by EWA and Owners staff for incorporation into the R-CAMP. The project cost estimates included in the R-CAMP include construction, condition assessment, study, design, engineering during construc tion, and construction management costs. These costs allow for current and future budgetary planning as part of the CIP.

R-CAMP projects have varying levels of detail and some are more defined than others. Generally, the cost estimates are Class 4 planning level cost s with a level of accuracy commensurate with levels developed by the Association for the Advancement of Cost Engineering (AACE) International which is provided in Table 2-2. As individual projects move advance with scope definition and design, the cost estimates should correspondingly be revised. 05/13/2025 C9 873 of 1078

Source: AACE International Recommended Practices 18R-97 Project costs estimates are developed through the following means:

1. Cost estimates for projects that were previously prepared outside of the R-CAMP, such as in studies, reports, or condition assessments, are incorporated into this R-CAMP.

2. Cost estimates for projects that were previously prepared as part of EWA’s previous budgeting process are incorporated into the R-CAMP.

3. Cost estimates for projects that were previously prepared as part of previous R-CAMP are incorporated into this R-CAMP.

4. Cost estimates of projects and items within the projects not previously developed are prepared and incorporated into the R-CAMP.

For cost estimates that were previously prepared, the Inflation Factor was applied to the previously prepared cost estimates. Cost estimates for this R-CAMP were updated to January 2022 (CCI 12996.09).

The baseline percentages for estimating const ruction costs are provided in Table 2-3. These percentages may be adjusted, at the discretion of the engineer/cost estimator, for each project if there is a greater amount of information known and de tail available to better define the project.

These percentages may also be adjusted if a previous cost estimate for the project was developed. 05/13/2025 C9 874 of 1078

Allowance amounts for additional project phase co sts for condition assessments, studies, design, engineering during construction, construction man agement, and electrical, instrumentation and control (EI&C) are included in the cost esti mates based upon percentages of construction costs.

The baseline rates for estimating these project pha se costs are provided in Table 2-4. These rates may be adjusted, or minimum costs may be used, at the discretion of the engineer/cost estimator, for each project. These rates may also be adjusted if a previous cost estimate for the project was developed. As detailed scoping of proj ects is defined and design level phases progress, these percentages should be revisited to review applicability of each cost and percentage.

A Basis of Estimate (BOE) which provides addition al costing assumptions and stipulations not summarized in this project cost estimating secti on is included as Appendix C. Cost estimates for the projects included in this R-CAMP are provided in Appendix D. Notes are included for each cost estimate providing additional information such as the source of the cost estimate and adjustments made in the percentages or rates.

EWA and Owners should implement sound project bidding practices to control project costs including pre-purchasing major assets to elimina te contractor mark-up, bid projects at a time of the year when the bidding climate is favorable, and design and bid similar projects together.

2.1.11. Project Prioritization
All projects identified in the R-CAMP are then prioritized by considering the evaluation scoring results and estimated costs. The scoring results di rectly relate to the impact that a project would have to EWA and Owners (a proj ect with a higher score woul d have a higher impact). Through this comparison projects may be assigned to one of four categories: (1) low cost and high impact, 05/13/2025 C9 875 of 1078
FY2023 R-CAMP Report
2-11
(2) high cost and high impact, (3) low cost and low impact, and (4) high cost and low impact. The benefit of this approach is that it allows EWA and Owners to better identify both cost and impact when prioritizing projects. The project prioritizati on process is discussed in further detail in Section 6 of this R-CAMP.

2.1.12. Implementation Schedule
The project prioritization process described ab ove provides EWA and Owners with informed condition and cost data to selec t which projects to schedule for implementation over the next six fiscal years (through FY2028). A recommended im plementation schedule is provided in Section

7. Projects that are not selected for implementation over the next six fiscal years are not scheduled or cash flowed in the R-CAMP. The implementation schedule is discussed in further detail in Section 7 of this R-CAMP.

2.1.13. Frequency of R-CAMP
The R-CAMP has historically been completed every two years. Vista has expressed some interest in reducing the frequency of R-CAMP updates. The Owners can decide to modify the frequency, but EWA recommends continuing the curren t frequency for the stations that are undergoing substantial improvements in the next few years so that EWA and Owners can adjust budgets as necessary. Both BVPS and AHLS are good exam ples of pump stations with significant improvements within the next few years and potentially a relocation for BVPS within the next 5- 10 years. It is recommended that R-CAMP to be updated every 2 years until the major renewals and improvements are implemented and then the frequency to be arranged based on the progression and dependency of the defined projects for e ach individual facility. Given that many projects initiate with preliminary study, it is importan t to communicate the progression on the identified tasks followed by recommendations and potential n eeds of the project. This is particularly important for the facilities that are undergoing major changes based on the R-CAMP assessments (i.e., BVPS relocation feasibility).

3. CONDITION ASSESSMENT SUMMARY
The benefit to a utility of a quantitative conditi on assessment is to better estimate both the estimated timing of asset failure and the impact such a failure would have on broader operations.

This allows EWA to develop more informed asset management pl ans and capital budget prioritization processes. While the age of an asset is an important consideration, the likelihood of an asset failing is mostly dependent upon the cond ition of the asset. As the condition of an asset deteriorates, the likelihood of fa ilure increases. Ultimately, th e goal of any condition assessment protocol is to acquire a more accurate knowledge of the timing of an asset failure. Having more confidence in determining asset failures and renewal needs will lead to more efficient and effective use of resources, and funds. Combination of fiel d condition assessment and focused condition assessment are performed. For the BCPS, RBPS, and BVPS a comprehensive condition assessment was performed in May 2021 followed by a site visit in October 2021, while for CWRF the focused condition assessment approach was used. Given that AHLS has recently undergone construction and significant rehabilitation effort, a site visit was performed for this remote facility.

3.1. FIELD CONDITION ASSESSMENT
In order to assess the current condition and the timing to asset failure, it is important to understand the ways an asset can fail. Assets can fail in four major ways (capacity, level of service, physical mortality, and financial efficiency) known as fail ure modes (shown in Table 3-1), which were used to assess the condition of each asset. Th ese failure modes were considered during the condition assessment and a condition score was a ssigned based on the most imminent failure mode.

A Level 1 (visual) condition asse ssment was conducted to assess the mechanical, electrical, and structural conditi ons of assets in BCPS, RBPS, and BV PS on May 2021. Condition of assets, system redundancies, installation years, quantitie s, and O&M assessment/needs were identified during the on-site facility condition assessmen t. Additionally, inputs from EWA staff, or contractors, as to when the asset was last serviced was used to complete the condition assessment. 05/13/2025 C9 877 of 1078

Asset condition was determined via visual inspecti on. Field observations were recorded with mobile devices utilizing customized condition assessment forms. The condition scoring system utilized and mobile devices with electronic forms is presented in Figure 3-1 . The condition assessment team assigned condition scores based on the International Infrastructure Management Manual with a rating range from 1 (Excellent condition) to 5 (Poor condition). Descriptions for each rating enable analysts to a ssign ratings to assets. All the data collected for each asset, including photographs of the assets, the inspectors’ notes, condition scores for specific attributes, inspection checklists, etc., was stored digitally.

The results of condition assessment are leveraged as one of the primary sources for identifying the needs for R&R act ions as well as required performance and maintenance activities to support operations. The detailed results of condition assessment are provided in Appendix F.

3.2. FOCUSED CONDITION ASSESSMENT
In the focused condition assessment approach, th e condition assessments are triggered by staff recommendation or when the CMMS identifies an asset that is within approximately five years of the end of its nominal service life or by staf f observations of condition. EWA manages its assets through its CMMS, eMaint, to whic h it recently transitioned from Munis. As a result, 132 assets are identified on CWRF for the Level 1 (vi sual) condition assessment.

4. STUDIES AND OTHER PROFESSIONAL SERVICES

4.1. STUDIES
Studies are necessary to provide planning informati on for maintaining the facilities. Studies are designated with an “S” prefix and are numbered according to their associated capital project. The studies are categorized as either “Conceptual Studies” or “Special Studies ”. Conceptual studies may be performed for more complex projects to de fine options to meet project requirements, to provide a life-cycle cost analysis of options, and evaluation of non-monetary factors. Special studies generally focus on organizational or facility-wide planning needs.

Descriptions of Special Studies and Conceptual Studies identified as part of this R-CAMP process are summarized below. Special and Conceptual Studi es have been assigned to either EWA or Owners and are provided for each facility.

4.2. BUNEA CREEK PUMP STATION STUDIES

4.2.1. EWA Studies
No studies assigned to EWA have been identified.

4.2.2. Owners Studies
S/P-9.4.008 Bypass
EWA staff noted that there is a n eed to bypass pump system installation so that the entire station can be bypassed in a proper and efficient way as needed. As an example, Scum and FOG abatement study was performed for BCPS, and the top three choices were identified. The Owner is ready to implement the recommended improvements for Scum and FOG mitigation, while there is a need for a bypass installation to facilitate the recommended improvements. This bypass pumping study will evaluate adding the allowance for bypass pump system installation on the BCPS. This study also aims to evaluate the possibility of simult aneous execution of the Mechanical Modification (formerly Modify Discharge Valve Installation) project and Scum and FOG abatement project.

Using the bypass pump system installation can facilitate the implementation of the aforementioned projects at the same time which helps reduce the cost by $0.5M.

4.3. RACEWAY BASIN PUMP STATION STUDIES

S/P-9.1.006 Containment Basin Repair
The containment basin at RBPS is used for up to 156,000 gallons of emergency storage during an interruption in pumping. The basin has noticeable cracking and most of the joint filler material needs repair, which allows consistent groundwater infiltration. Preliminary investigations have determined that repair of the ba sin should include pressure relief from the groundwater pressure anticipated beneath the basin once the infiltrati on has been mitigated. It should be noted that the groundwater is expected to continue infiltra ting into the basin by addressing the structural deficiencies of basin (i.e., cracks and joint fillers). However, the basin can drain by gravity to the wet well. Also, a sump pump can be added as an additional alternative for draining the wastewater from the basin.

Figure 4-1: Field Condition Assessment Results for CWRF The basin is also difficult to access, as the pump station access road ends prior to the containment basin access gate, the access gate is within proximity to nearby shrubbery, and the access gate has been placed at an offset from the containment basin access ramp.

This study is related to the 2014 R-CAMP study S-9.1.001 (2021 R-CAMP study S-9.1.006) and
will evaluate potential methods of pressure relief and repair for the containment basin as well as improve basin access. It is recommended for this study to evaluate modification of the basin fence line to allow a vactor truck to offload into the containment basin if necessary. Access from either the Faraday side, the Melrose side, or both is desired. Modification of the containment guardrail may be required pending the placement of the fence line.

S/P-9.1.009 Pump Station Resiliency
The RBPS is located within close proximity to a nearby creek. With climate change, large storms may become more frequent and more significant, which could cause flooding at the site during heavy storm events. The SDG&E cabinet is located along the back of the pump station building, which is within sufficient proximity to the creek to be at risk of flood damage. 05/13/2025 C9 883 of 1078
FY2023 R-CAMP Report
4-3
This study is related to the 2021 R-CAMP study S-9.1.009 and will assess the potential for future flooding and will investigate options to protect the SDG&E cabinet and other key assets from potential flooding, such as elevating equipment or building an embankment.

4.4.1. EWA Studies
No studies assigned to EWA have been identified.

4.4.2. Owners Studies
S-9.3.010 Buena Vista Pump Station Facility-Level Alternative Analysis (Formerly known as Relocation Study)
This facility-level alternative analysis is a study to determine the future of the pump station. The analysis would help select an alternative or a pha sing plan that considers cost, benefits, levels of service, and other future goals associated with the pump station, such as expansion plans.

Alternatives to consider include:
x Replace BVPS with a new pump station
x Keep the existing pump station and implement Major Equipment CIP x Phasing between implementing a major CIP and building a new pump station x Evaluation of generator system
The results of this study will need to be inco rporated into the Major Equipment CIP project and closely coordinated with other rehabilitation ef forts, as the Owners may choose to run certain assets to failure leading up to a full station rep lacement, rather than investing in significant rehabilitation. This effort will be a feasibility and planning study to assess replacing the existing BVPS with a new pump station in the next 5-7 y ears. The study will need to assess project objectives, potential locations, permitting approach, timeline, and planning level costs. The results will need to be incorporated into the next cycle of R-CAMP and closely coordinated with other rehabilitation efforts, as the Owners may choose to run certain assets to failure leading up to a full station replacement, rather than investing in significant rehabilitation.

S/P-9.3.008 Major Equipment CIP
The scope of Major Equipment CIP project includes tasks associated with large facility component replacement or repair required within the next 3-5 to be coordinated with facility level alternative analysis and future master plans. There is an in itial study phase to ev aluate the priority and feasibility of implementing the repair or rehabi litation of large facility component based on the facility-level alternative analysis and the needs identified through future master plans. The list of facility components requires replacement or repair within the next 3-5 years depending on the facility level alternative analysis are as follow:

S/P-9.5.008 RO Rehabilitation
This study will evaluate the rehabilitation a nd replacement required to recommission the RO system at a future date. This effort will be a planning study to assess the condition of assets in RO system and the recommissioning RO system in order to make it operable, if Owner determines this is best option to meet Carlsbad recycled water quality and supply goals.

RO membrane replacement suggested per RO Inspection Report and 2014 R-CAMP project P-

9.5.003 Reverse Osmosis Membrane Replacement.

Additionally, based on the 2014R-CAMP project P-9.5.004 RO Chem Feed System Modifications, Water Quality study is needed to verify th e need for sulfuric acid and assess membranes and operations to account for changes to the supply water quality from conservation, desalination, and State Water Project water versus Colorado River Water.

FY2023 R-CAMP Report
4-5
According to the 2021 R-CAMP, the following recommendations had been made based on the RO Inspection Report and the condition assessment:
x Remove remaining stored sulfuric acid and implement storage tank protection x Replace the missing vent valve on top of the sulfuric acid tank x Paint exposed PVC, fiberglass railing, and rusted parts x Consider repairing ends of damaged RO vessels
x Protect instruments showing signs of corrosion
x Place fresh desiccant in all electrical panels and seal the panels properly on all sides to prevent moisture from entering the panel
x Review and revise preventative maintenance program
o Exercise pumps and motors quarterly, or at a minimum every six months, to o prevent frozen bearings
o Replace desiccant in electrical panels at recommended frequency or when color o change indicates spent desiccant
o Exercise motorized and manual valves quarterly, or at a minimum every six o months, to prevent sticking
The RO rehabilitation project is dependent upon the outcome of the facility-level assessment that includes a study on the feasibility of RO, MF and UF processes to identify alternatives. The condition of MF and RO is unknown as they ha ve not been operating for a long time and recommissioning may not be technically or economically viable. A study can confirm which action can be more beneficial.

This study assists to determine whether it is a need to bring the RO back online and to identify the most feasible and best economical approach to meet Carlsbad recycle water quality and supply goals.

S/P-9.5.009 MF Rehabilitation
This study will evaluate the rehabilitation and replacement required to recommission the MF system at a future date. This effort will be a planning study to assess the condition of assets in RO system and the recommissioning MF system in order to make it operable, if Carlsad desires this to meet recycled water quality and supply goals. The MF is still a component of the existing permit, even though hasn’t been operated recently.

The MF rehabilitation project is dependent upon the outcome of the facility-level assessment that includes a study on the feasibility of RO, MF and UF processes to identify alternatives.

S/P-9.5.010 Granular Media Filters (GMF) Bypass
In 2016, the Master Recycling Permit was upda ted by the California Reginal Water Quality Control Board to reflect proce ss changes that occurred at th e conclusion of CWRF Phase III expansion. With the updated permit, CWRF was issued updated compliance standards. CWRF is required by permit to produce recycled water below a maximum turbidity level for each treatment train, as measured at the effluent of each treatment train. Prior to the Permit update, CWRF effluent turbidity was measured only at the end of the Chlorine Contact Tank (CCT). The updated Permit requires turbidity compliance points to be located immediately downstream of each treatment train, which can be problematic for the GMF. Upon Plant startup, system startup and other nonstandard operating conditions, GMF effluent may temporarily exceed the maximum allowable turbidity limit, causing the water to be considered “off -spec” and non -compliant. The GMF does not currently have an off-spec drain back to EWPCF.

During current “off-spec” events, the GMF effluent still has to flow through the CCT prior to being diverted to the EWPCF, thereby making any othe r water in the CCT also non-compliant. This requires the CCT to be drained prior to restarting the production of compliant recycled water which can take up to six hours.

This study has been identified in 2021 R-CAMP. This study will evaluate installing a new off-spec pipeline from the GMF effluent to bypass the CCT and return directly to the EWPCF or other options to mitigate turbidity spikes such as relocating or averaging turbidimeters or requesting permit modification for more variations during startup period.

EWA staff suggested the GMF effluent that is bypassed should be routed back to EWPCF via the existing junction box near the SEEPS generator. This project should include upsizing the junction box to take the full flow of CWRF; therefore, allowing subsequent programing modification to allow for CWRF "failsafe" interlock.

S/P-9.5.014 Access between CWRF and CPS
During the
October 2021 condition assessment, EWA staff noted that there is a need for footpath between CWRF and Combined Pump Station (CPS) for routine maintenance of the CWRFs’ assets that are located at the CPS. Due to elevation difference between CWRF and CPS and lack of proper access between these two facilities, there are sa fety concerns for opera tional staff to perform routine maintenance on the assets owned by CWRF and located at CPS. This study will evaluate the alternative options for improving access between CWRF and CPS.

S/P-9.5.015 Clean-In-Place Chemical Optimization
(Formerly was EWA’s project (S-38002-004), transferred to Owner’sproject) This is related to 2021 R-CAMP study S-38002-004. The operations staff noted that the sodium bisulfite and citric acid storage tanks are re filled every couple of weeks. During commissioning and performance testing of the ultrafiltration sy stem (UF) in 2016-2017, chemical use was increased above the intended design dosing to successfully pass the test to sufficiently recover the 05/13/2025 C9 887 of 1078
FY2023 R-CAMP Report

transmembrane pressure. EWA staff have tried to optimize the chemical dosing, but the dosing is still more than the original design parameters, so chemical deliveries are required more frequently than the design intent.

This study will evaluate the optimal size of the chemical storage tanks to minimize the frequency of deliveries and assess other chemical system optimization, such as containment. This study may also review sodium hypochlorite storage requirements. Optimization of the storage tanks sizes may provide long-term cost savings through minimizing th e frequency of chemical deliveries, as well as additional facility resiliency in regard to spill risk/ exposure mitigation during chemical deliveries, protection from chemi cal supply chain and driver short ages, and ability to resource share if needed with EWPCF or other agencies.

S/P-9.5.016 Facility Level Assessment
With upcoming increase in the CMWD’s recycle water demand, the Owner plans to leverage the potential existing components and assets in the CW RF to meet their recycled water quality and supply goals. A whole facility level assessment is recommended to align objectives and establish road map.

For this purpose, evaluating the installation of a new off-spec pipeline from the GMF effluent to bypass the CCT and return directly to the EWPCF needs to be investigated. In addition, there is a need to assess whether the recommission of MF and RO or expansion of UF system is more technically and economically feasible.

The UF can produce higher quality water than the GMF and was installed to treat a greater variety of supply water. The UF can treat up to approximately 20 Nephelometric Turbidity Unit (NTU) in comparison with the GMF which can treat 2 to 3 NTU. Unlike the UF filters, that provide an absolute barrier, the GMF media allows for pa ssthrough of some feed water constituents. As a result, operating the UF more frequently would result in higher quality water but reduced flow capacity and increased chemical, electrical, and mechanical costs. The Owners plan to evaluate the installation of strainer at GMF feed pumps as an alternate engineered solution to increase GMF effluent water quality and resiliency.

During the condition assessment in
October 2021, adding isolation valves to each individual UF module was identified to help isolate each module as needed. In addition, EWA staff noted that adding a sluice gate to north side CCT would al low isolation of each basin for as needed maintenance.

This study will assess the installation of a new off-spec pipeline, feasibility of MF, RO and UF to identify alternatives, installation of strainer at GMF feed pumps, installation of isolation valves for UF modules, and adding a sluice gate to the north side of CCT.

In addition, any proposed major equipment replacement and rehabilitation in P-9.5.013 project and considered as owners’ items for recycled water pump station is recommended to be evaluated through a study by Owners (e.g., strainer, conduit issues from ground settling, etc.). 05/13/2025 C9 888 of 1078

5. IDENTIFICATION OF PROJECTS
This section provides an organized reference for R-CAMP projects that are recommended for funding in the next six years and beyond. Since the remote facilities are owned by the Owners and are operated and maintained by EWA, the projec ts discussed within this section were collaboratively assigned to th e EWA or Owners, with EWA genera lly taking responsibility for smaller maintenance projects and Owners generall y incorporating for the larger capital projects into their own CIPs for that facility. There may be exceptions for efforts that may be better suited for a specific lead agency.

Project descriptions for potential projects that have been identified include a project background, description, justification/consequences, a nd/or project delivery method. The project delivery methods considered in the R-CAMP include traditional in-house services, contracted services, and design-bid-build (DBB) as well as alternati ve delivery methods including design-build (DB), design-build-operate (DBO), design-build-own-operate (DBOO), etc.

R-CAMP projects were developed based on completed condition assessments and facility needs assessments, asset age, other reports, or EWA staff observations since the preparation of the previous R-CAMP. Some staff observations result in a project with design criteria in which EWA and Owners reach consensus during the R-CAMP process, and these projects are added to the list.

These projects typically include a design phase prior to the project implementation phase. Other observations require a special study to address an issue or concern that is identified, which will identify a specific R-CAMP project later.

Through discussions between EWA and Owners, project responsibility is assigned to either EWA or Owners for each project.

P-37002-001 Minor EI&C Rehabilitation
Background
During May 2021 condition assessment and October 2021 site assessment, several locations of potential electrical and instrumentational deficiencies were noted throughout BCPS. The deficiencies were indicative of wear due to age and include recommended improvements for additional control redundancy and improved safety through testing plans and additional equipment monitoring.

Description
Perform minor EI&C maintenance throughout BCPS, including:
x Integrate On-net Surveillance Systems (onSSI), Inc. to the remote cameras x Instrumentation access: Add a hand access hole with new transducer for access to wet well level transducers without entering the wet well. Relocate level and flow transmitters outside of the PLC for greater accessibility or add a remote readout x Circuit organization: Known as wiring in previous R-CAMP x Panel protection: Replace misplaced ra ceway box covers, damaged conduit, and damaged fiberglass LCP
x Pressure transducer replacement: Replace 2 of the Pressure Transducers that deal with Levels. The current setup is bulky and can fault-out when rags get entangled on the sensor this can result in faulty inaccurate readings. Replace with a Vega Pressure transducer will help to eliminate these fau lty reading due to the sleek design that is capable of being put down a slotted holed stainless-steel tube, thus keeping rags out of the readings
x Camera improvements: Add one camera

The final scope and priority of task s associated with Major Equipment CIP is determined by the Facility-Level Alternative Evaluation Study.

Description
BVPS can be improved via the following projects:
x Replacement of aging equipment, such as:
o Automatic Transfer Switch
o Motor Control Center
o Switchboard
x HVAC: Installation of air conditioning in the MCC room x Headworks gates and grinders: Development of a headworks bypass system, which may include in-line grinders or a grinder vault outside of the headworks. This potential project relates to Project P-9.3.001 from the 2014 R-CAMP
x Valves: Replace solenoid valve
x Grating
x Roofing: Replacement of the pump station roof due to water leakage above electrical equipment
x Replace 2” backflow device: Replace 2” backflow at duck pond x Evaluation of berm: Evaluate if the elevati on of the creek berm is enough to protect the station from a significant storm event similar or greater than the storm on April 10, 2020.

During that rain event water was at the top of the berm and broke upstream of the station, which caused flooding of Oceanside's Buena Vista pump station and freeway. If April 10, 2020 would have been a high tide, water would possibly have crested the berm into the station resulting in infiltration into the we t well and overcome the station's pumping capacity. Berm improvements have been co mpleted upstream of BVPS where the berm broke during that storm, so the concern is that the weak spot may be at our station Justification/Consequence
Replacement of aged equipment will improve station reliability and increase site safety. Additional improvements will enhance facility robustness.

P-9.3.010 Buena Vista Pump Station Facilit-Level Alternative Analysis (Formerly known as Relocation Study)
This project has currently been identified as a study. Information on this study can be found in Section 4 (S-9.3.010). The analysis would help select an alternative or a phasing plan that considers cost, benefits, levels of service, and other future goals associated with the pump station.

The study will need to assess project objecti ves, potential locations, regulatory strategy and permitting approach, timeline, and planning level costs. The results will need to be incorporated into the next cycle of R-CAMP and closely coordinated with othe r rehabilitation efforts, as the Owners may choose to run certain assets to failure leading up to a full station replacement, rather than investing in significant rehabilitation. Once decided what to do, circle back to Major Equipment CIP.

P-31002-001 Minor EI&C Rehabilitation
Background
During the October 2021 site assessment, several loca tions of potential electrical and instrumentation and controls deficiencies were noted throughout AHLS. The deficiencies were indicative of age. The assessment includes re commended improvements for additional control redundancy and improved safety through testing plans and additional equipment monitoring.

Description
Perform minor EI&C maintenance throughout AHLS, including:
x Grinder Supply fan LOR switch relocation: The grinder building supply fan LOR switch is located within a confined space, and the switch should be moved outside of the grinder building. It is difficult to enter the space to start the fan if the atmosphere is poor, but the fan must be on to make the atmosphere acceptable to enter x Install air flow monitoring equipment: Install inline air flow monitoring equipment into the Humidifier feed line to ensure that proper air balance is achieved (design flow is ≥ 8,300 scfm). In addition, inline air flow mete r needs installation of either a handheld airflow monitors or inline flowmeter.
x Site camera improvement: Site security needs to be improved. Camera system should be evaluated to ensure that there are no blind spots. Adding extra camera can help mitigating the potential risks for the station. Ca mera feed is now viewable at EWPCF control room; however, Camera feed is curr ently intermittent. EWA is awaiting the completion of secondary server room to enable full functionality. x Install camera in wet well with feed viewable onsite within the MCC for the purpose of evaluating wet well cleaning effectiveness without the need for additional staff to be 05/13/2025 C9 922 of 1078
FY2023 R-CAMP Report
5-35
onsite for a confined space entry. Camera s hould be mounted on East wet well room wall with field-of-view of the length of wet well floor and sluice gate. x Grinder control panel relocation: Grinder control panels must be protected from unauthorized use to prevent a sewage spil l. Moving the operations of grinders control panels on the roof of the inlet structure is suggested. x Generator improvement for redundancy: There is no redundancy in the system, and if the generator gets disconnected, it cannot be notified. Therefore, it is a need to allow for generator notify operators or an alarm fo r disconnect cabinet. The accessibility of the generator disconnect switch is very critical. If unauthorized individuals or operational staff accidentally ope ns generator disconnect pa nel, it can disconnect the generator. Generator fuel level is also not functioning. x Bubbler control improvement: No redunda ncy is on bubbler control. Currently, only the bubbler has programming with pump interlocks. The Program needs to be redundant to allow the ultrasonic controllers to have the same function as the bubbler.

In addition, only the online controller should have pump interlock programming active and should readily swap controller if the selected controller fails. x Installing flow meter bypass: No flow meter Bypass. Not part of DB. x Conduit improvement to avoid leakage: Light switches, the conduit leaks/ leaks through cabinets every time it rains it leaks.

6. PROJECT EVALUATION AND PRIORITIZATION
After the R-CAMP projects have been identified, each project assigned to EWA and the Owners is individually evaluated, ranked, and scored based on a set of selected evaluation criteria. The projects are then prioritized using a comparison of project scores versus project costs. This section describes the process of evaluating and prioritizing projects which is a step towards development of a project schedule and cash flow.

6.1. EVALUATION CRITERIA
The six evaluation criteria for evaluating projects are listed and defined below.

1. Safety – This criterion assesses improvements required to maintain a safe working environment for EWA personnel and visitors as well as the impact that a project will have on the risk of an accident occurring.

2. Regulatory Compliance – This criterion assesses the ab ility of a project to impact compliance with current and/or anticipated regulatory requirements.

3. Reliability – This criterion assesses the timeframe in which existing assets related to a project will reach the end of their useful life and the potential consequence of the assets reaching the end of their useful life before replacement or rehabilitation.

4. Public and EWA Impacts – This criterion assesses the impact that a project will have on sound levels, appearance (sight), and traffic levels to EWA and the public at the remote sites.

5. Energy Efficiency – This criterion assesses the energy effectiveness and benefits of implementing a project through a reduction in en ergy usage and increase in energy self- sufficiency.

6. Organizational Efficiency – This criterion assesses the ab ility of a project to impact EWA’s capacity to manage resources, achie ve goals, and create a positive worki ng environment for personnel.

The six evaluation criteria have b een assigned a criticality factor from 1 to 6 with 1 representing the lowest level of importance and 6 representing the highest. Each criticality factor has been uniquely assigned to each evaluation criteria. Th e assigned criticality factors stay with their corresponding evaluation criteria throughout the project evaluation process. The criticality factor assigned to an evaluation criterion reflects the relative level of importance of each criterion. Table 6-1 provides the evaluation criteria and their assigned criticality factors. 05/13/2025 C9 939 of 1078

Regulatory Compliance 5
Reliability 4
Public and EWA Impacts 3
Energy Efficiency 2
Organizational Efficiency 1

6.2. IMPACT FACTORS
Each project has been assigned an impact factor across each of the six defined evaluation criteria from 0 to 5. An impact factor of 0 represents the lowest (minimum) factor and 5 represents the highest (maximum) factor. The impact factors provide a relativ e comparison of each project’s ability to satisfy each of the defined evaluation criteria. Table 6-2 provides the parameters that were used for assigning impact factors to projects against the evaluation criteria.

6.3. EVALUATION SCORING RESULTS
The impact factors assigned to a project for e ach evaluation criteria are then multiplied by the criticality factor of the evaluation criteria to calculate criteria scores as seen in the formula below. ݎ݋ݐܿܽܨݐܿܽ݌݉ܫ
The six criteria scores are then summed to determine the evalu ation score for each project. The scoring results for FY2023 R-CAMP projects are provided in Table 6-3 through Table 6-12 by ascending project number and by descending score according to project responsibility designation.

These scoring results demonstrate the overall be neficial impact to the EWA organization in meeting its mission, goals and objectives.

Projects in the R-CAMP may either need to be funded and initiated or may have already been initiated but still require more funding. Projects that have already been initiated but still require more funding are not scored in the R-CAMP since they have previously been selected for implementation. Projects that are reoccurring, such as on an annual basis, need to be funded and initiated each time they are scheduled to occ ur. Condition assessments, engineering services, special studies, and other services are not scored.

6.4. PROJECT PRIORITIZATION
The projects in the FY2023 R-CAMP are prioritized by taking into consideration the evaluation scoring results (organization impact) and costs, as illustrated in Figure 6-1 through Figure 6-5.N o t all projects are provided on this figure due to th eir higher costs which impacts the scale of the figure. However, these projects are still evaluate d and compared to the other projects in the R- CAMP. Through this comparison, projects may be assigned to one of the following four categories:

1. Low cost and high impact – Highest Priority Projects provide EWA with the highest organization impact relative to their cost. Due to their relatively lower costs such projects may be more readily implemented than proj ects requiring greater capital. These may constitute, “near-term” project priorities to be implemented quickly and efficiently.

2. High cost and high impact – Priority Projects are those projects that provide a high organization impact, but because of their relatively high cost, may require additional time to implement due to the complexities inherent in larger capital projects. These projects may garner the most attention in EWA’s CIP.

3. Low cost and low impact – Mid-Priority Projects are those projects in which their relative low cost is matched by their relatively low organization impact. Such projects should be prioritized after addressing the above two categories of projects.

4. High cost and low impact – Low Priority Projects deliver relatively low organization impact relative to their cost and should be considered only after the above-listed categories of projects are addressed, or in combination with other projects (which may improve their cost/benefit).

The comparison of project costs and organization impact allows EWA to consider both costs and scoring results in prioritizing, funding, and scheduli ng its CIP. Since recurring projects are not scored, they are not shown here.

7. RECOMMENDED PROJECT IMPLEMENTATION SCHEDULE AND

COST SUMMARY

7.1. IMPLEMENTATION SCHEDULE AND COST SUMMARY
The recommended project implementation schedule and cost su mmary is based upon the project evaluation and prioritization process presented in this R-CAMP. The implementation schedule and cost summary provide a breakdown of projects based on the year(s) they are assigned to. The recommended project implementation sche dules for prioritized projects for FY2023 through FY2028 are presented as Figure 7-1: Recommended Implementation Schedule for Prioritized BCPS Projects through Figure 7-1 through Figure 7-5. The projected costs by fiscal year for prioritized projects are presented in Table 7-1 through Ta ble 7-5. The capital improvement budgets for projects planned for execution over the next six years, FY2023 through FY2028, are summarized in Table 7-1 through Table 7-5 by category related to the facility.

7.2. WHAT’S NEXT
The recommended project impleme ntation schedule and projected cost summary is provided to give EWA staff and Owners the information th at can be leveraged during the budgeting process.

EWA staff and Owners can utilize this informa tion as a decision-making roadmap in their upcoming budgeting process.

Every year the E-CAMP or R-CAMP is updated on an alternating basis. In Spring 2021, EWA updated the E-CAMP prior to the start of FY 2022. EWA will update it next in Spring 2023 prior to FY 2024. Then EWA will treturn to updating the R-CAMP in Spring 2024 prior to FY 2025, and so forth
Subsequent R-CAMPs will monitor and re-evaluate projects within and beyond the six-year implementation schedule provided in this R-CAMP, including incorporating recommendations from studies. Common themes of these projects that should continue to be evaluated and considered include:
x Rehabilitation and replacement of aging infrastructure x Facility expansion and coordination with Owner master planning efforts x Improvements to reduce impacts to the public and EWA (such as sound, appearance, and traffic)
x Efficiency optimization
x Future regulatory and industry trends

Appendix B: Basis of Estimate
PROJECT INFORMATION:

Client: Encina Wastewater Authority
Project: FY2023 R-CAMP
Estimate Date: 1/1/2022
Estimate Type: Preliminary
AACEI Class Level Estimate: 4
PROJECT DESCRIPTION:

The R-CAMP and related documentation is updated to provide a current, organized register of major assets and associated estimated asset service life remaining for the major equipment and materials at the remote facilities. Through the R-CAMP, EWA staff and Owners’project short and long-term future expenditures for capital improvement projects. Scope of projects included are described in the R-CAMP under Section 4 and Section 5. Projects vary in nature from studies to maintenance projects. Estimates are provided to provide planning level order of magnitude costs.

ESTIMATE DOCUMENTS:

DRAWINGS: N/A
DOCUMENTS: FY 2022 Operating & Capital Budget
COSTS PROVIDED BY OTHERS: Encina Wastewater Authority,
R-CAMP Report 2021,
Quotes provided by third parties to
Encina Wastewater Authority
SOURCE OF COST DATA:

Costs for previously estimated projects, in particular FY2021 R-CAMP, were obtained from documents listed above with adjustment to current ENR CCI as described below under escalation and by applying inflation factor to reflect the annual increase in the estimated costs. New projects were estimated using RS Means CostWorks 2021 data, Hazen’s internal estimating database, and project data from similar reference projects. Allowances were used for items where scope was less defined.

ESTIMATE ASSUMPTIONS:

The followings assumptions were made in the preparation of this estimate:

For purpose of these estimates the following conditions were assumed unless specifically called out otherwise in the individual project estimates:
05/13/2025 C9 970 of 1078
FY2023 R-CAMP Report
Appendix B2
Some projects will be publicly bid and prevailing wage requirements will apply. Regular working hours will be allowed (7:00am - 5:00pm). Some projects will be completed in-house.

SPECIFIC INCLUSIONS:

The estimate does not include the following:

Contaminated soils removal or disposal not included unless specifically listed in project descriptions.

Hazardous or Special Waste removal or disposal not included unless specifically listed in project descriptions.

No special foundations or piles are included unless specifically listed in project descriptions.

Owners Costs for program management, legal and admi nistration costs, agency funding coordination, permitting, and public outreach are not included.

A project contingency is included for each project. This contingency is to include an allowance for indeterminates, and work items where scope is not fully detailed at this stage of design. Typically, as design level progresses the contingency is reduced. For p rojects which do not yet have a preliminary design completed a project contingency of 40% was used. Some specific projects that have a more defined and limited scope defined a lower project contingency was used. The percentage used for each project is shown on the individual project estimate. For some projects, the contingency was adjusted based on the complexity of the projects.

Note: This allowance is intended to provide a Design Contingency allowance. It is not intended to provide for a Construction Contingency for change orders during construction or to cover unforeseen conditions.

ESCALATION:

An escalation factor has not been included. Owners should include escalation to adjust cost to project schedules.

The Owners are cautioned that the project cost should be adjusted for any changes in the project schedule.

ENR CCI Jan -2022 12996.09 12144.49 Jan-2020 Los Angeles Annual Inflation Escalation Factor: Not included
ACCURACY:

The level of accuracy is commensurate with leve ls developed by the AACE, the Association for the Advancement of Cost Engineering International. At increasing levels of design completion, the narrower the range between upper and lower limits and the greater the accuracy of the estimate. These estimates are considered a Class 4 level estimate in accordance with AACE guidelines and are meant for planning purposes. Typically, this level of estimate has an expected accuracy range of +50 on high side and -30% on low side.

The enclosed Engineer’s Estimate of Probable Construction Cost is only an opinion of possible items that may be considered for budgeting purposes. These Probable Construction Cost Estimates are limited to the conditions existing at issuance and are not a guaranty of actual construction cost or schedule. Uncertain market conditions such as, but not limited to, local labor or contractor availability, wages, other work, 05/13/2025 C9 971 of 1078

material market fluctuations, price escalations, forc e majeure events and developing bidding conditions, etc. may affect the accuracy of this estimate. Hazen is not responsible for any variance from this Probable Construction Cost Estimate or actual prices and conditions obtained. 05/13/2025 C9 972 of 1078

Replacement
Replace 2 of the Pressure Transducers that deal with Levels. The current setup is bulky and can fault out when rags get entangl ed on the sensor this can result in faulty inaccurate readings. Replacing with a Vega Pressure transducer will help to eliminate these faulty reading due to the sleek design that is capable of being put down a slotted holed stainless-steel tube, thus keeping rags out of the readings.

UF/ MF pumps require seal water to operate. Seal water is supplied via EWPCF 3whp. EWPCF frequently has 3whp variations in availability of supply, pressure, and turbidity. The 3water system at EWPCF is heavily taxed and has caused operability issues for the heat dryer. Consider use CWRF's reclaim water supply located at East Storage Basin to supply UF/ MF seal water system as the primary supply and retain EWPCF 3whp as a redundant system. obtain any permits as required for title 22 usage or investigate if permits is required as it would be used exclusively for CMWD's benefit on their recycled water supply system. alternatively, a booster pump or hydropneumatic tank could be used to ensure adequate pressure is available for seal water. Hazen proposes an alternative solution to provide the seal water through each individual pump heads.
