Project (CIP No. )XX)
17.4 Further, an extension in Contract Time will not be granted unless DB can demonstrate through an analysis of the Project Schedule that the increases in the time to perform or complete the Project, or specified part of the Project, beyond the corresponding Contract Time arise from unforeseeable causes beyond the control and without the fault or negligence of DB, its Design Consultants, and subcontractors or suppliers, and that such causes in fact lead to performance or completion of the Project, or specified part in question, beyond the corresponding Contract Time, despite DB's reasonable and diligent actions to guard against those effects.
17.5 DB carries the burden of proving an entitlement to an increase in the Contract Time.
Delays attributable to and within the control of Design Support Consultants, or subcontractor or supplier shall be deemed to be delays within the control of DB. No time extension will be allowed for such delays. An increase in Contract Time does not necessarily mean that DB is due an increase in the GMP.
Section 18: Late Completion
18.1 City and DB recognize that time is of the essence in this Agreement and that City will suffer financial loss if the Project is not completed within the Contract Time, plus any extensions thereof allowed in accordance with Section 17.3. They also recognize the delays, expense, and difficulties involved in proving in a legal proceeding the actual loss suffered by City if the Project is not completed on time. Accordingly, instead of requiring any such proof, City and DB agree that DB shall pay as liquidated damages (but not as a penalty) for each calendar day of delay beyond the time specified for Substantial Completion of the Project, the following amounts which DB expressly agrees are "not unreasonable under the circumstances" as defined in California Civil Code §1671(b): !!! or each calendar day.

19.2 When City desires a change in the Project, City may issue a Request for Proposal to DB.
DB will be required to respond within the time indicated by City.
Section 20: INTENTIONALLY LEFT BLANK.
Section 21: Work By Others

The City will give DB reasonable notice of its intent to do such other work. DB's work shall take priority over the City Contractors; but the Parties will use their best efforts to coordinate their work so as to minimize the disruption to each other's work and to allow City Contractor to proceed expeditiously.
21.2 If the proper execution or results of any part of DB's work depends upon the work by the City or City Contractor, DB shall promptly inspect and report to City in writing any apparent delays, defects, or deficiencies in the City's work that render it unavailable or unsuitable for such proper execution and results.

Prompt notice of defects known to City shall be given to DB. All Defective Work, whether or not in place, may be rejected, corrected, or accepted as reasonably directed by City, provided DB shall not be entitled to an extension in Contract Time or increase in GMP because of any delay or increase in cost attributable to the rejection, correction or acceptance of said work. Defective work may be rejected even if approved by prior inspection. Substantial

If circumstances warrant it, including but not limited to, in an emergency, City or DB may have the defective work corrected or the defective work removed and replaced. In that event, DB shall not be allowed to recover any associated costs, and DB shall reimburse City for all direct, and indirect costs of City, and City shall be entitled to an appropriate decrease in the GMP, to withhold a setoff against amount recommended for payment, or make a claim on DB's bond if DB has been paid in full.

23.2 While City has such possession or use, DB shall be relieved of the responsibility for the loss of or damage to the Work resulting from City's possession or use. If prior possession or use by City delays the progress of the Work or causes additional expense to DB, an equitable adjustment shall be made in the GMP or the Contract Time, and the Agreement shall be modified in writing accordingly.
Section 24: Personal Services and Non -Assignability
24.1 This is a personal services Agreement and, therefore, DB shall not alter the key employees or Design Consultants nor assign or transfer, voluntarily or involuntarily, any of its rights, duties or obligations under this Agreement except upon the prior written consent of City. Any such change, assignment or transfer without the prior written consent of the City shall be deemed null and void and constitute a material breach under this Agreement.

Raceway Basin (8320) & Buena Creek (8324) Pump Station - Fog Abatement, Raceway Basin Overflow Imp. (8321) & BCPS Mechanical Valve Mods (8345)
3.0 PROJECT DESCRIPTION
The project is in the City of Vista at the Buena Creek Pump Station (BCPS) located near S.
Melrose Dr. and Green Oak Rd, and the Raceway Basin Pump Station (RBPS) located near S.
Melrose Dr. and Faraday Ave. The BCPS and RBPS are owned by Buena Sanitation District (BSD) and City of Vista (CoV); however, the pump stations are operated and maintained by Encina Wastewater Authority by contract.
The BCPS was built in 2002 and conveys raw wastewater to the Encina Water Pollution Control Facility (EWPCF) in Carlsbad. The pump station has a design capacity of 8.8 million gallons per day (MGD) and an average daily flow of 2.1 MGD. Influent wastewater enters the pump station through dual 24 -inch pipelines. Before entering the wet well, influent water passes through parallel channel grinders. Effluent water leaves the pump station through a 24 -inch ductile iron pipeline that connects to an 18 -inch polyvinyl chloride (PVC) force main.
This force main ultimately joins BSD's force main to the EWPCF.
The City owns the RBPS. In 2007, the facility was replaced with the current facility, which has a design flow of 1.9 MGD. The current average daily wastewater influent flow is approximately 0.5 MGD.
Encina Wastewater Authority (EWA) provides operational, maintenance, and administrative contract support services under a Memorandum of Understanding (MOU) agreement with the City. BCPS and RBPS are considered critical infrastructure to the City' s sanitary sewer system.
Both stations are experiencing routine Fats, Oils, and Grease (FOG) accumulation. The operation and maintenance (O&M) staff are spending hours per week breaking down the FOG build up in the wet wells. Staff use water hoses to break down the FOG mat in the wet well to their best of abilities and increased pump speed to drain the wet well.
The City and District contracted with HDR, Inc. to study the FOG issue and evaluate several solutions at BCPS and Raceway Basin Pump Station, which is also experiencing FOG accumulation. The resulting Technical Memorandum titled "Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum" dated July 20, 2021, is included as Appendix D of this RFP. The study carefully evaluated several different technologies against robust evaluation criteria and found that a large volume air bubble mixer by Pulsed Hydraulics, Inc. (PHi) to be the best alternative to mitigate the FOG accumulation issue at BCPS and RBPS.
Additionally, there are approx. 24 valves within the BCPS that require replacement and a seized (open) isolation gate within the wet well that requires repair or replacement at the Buena Creek Pump Station. The BCPS pump discharge piping is configured with 8 -inch and 12 -inch piping and valves, to allow for pump isolation and varied operating modes. Six of the plug valves are configured such that under normal or primary modes of operation, the seating side of the valve is incorrectly facing the unpressurized side of the system. A May 2021 condition assessment and October 2021 site assessment identified required mechanical modifications including replacement of all the discharge valves and removal and replacement of six plug valves ensuring seating side of valve faces pressurized side of system. In addition, there are several suction valves that are leaking. These valves are direct like for like replacements but likely require station bypass. 2 1191/ 2U25 1

Raceway Basin (8320) & Buena Creek (8324) Pump Station - Fog Abatement, Raceway Basin Overflow Imp. (8321) & BCPS Mechanical Valve Mods (8345)
The BCPS force main manifold piping includes some ability to isolate pumps three, four, and five for maintenance purposes, however pumps one and two lack such ability. With potentially minor modifications, isolation of pumps one and two may be possible. The District wishes to also analyze and potentially construct modifications to the BCPS manifold piping to allow for future isolation of each side of the force main manifold so that future valve maintenance can be achieved without externally bypassing the pump station.
Though discussions with PHi indicate that the pulsed air bubbler FOG abatement system can be manufactured / engineered to be installed in the wet wells in a live low flow condition, it is anticipated that the system will be installed at the same time as the mechanical valve replacements / modification during a bypass operation at the Buena Creek Pump Station.
However, since no other work is proposed at Raceway Basin Pump Station, the PHi system will only be implemented if it can be installed in live and/or low flow conditions without an external bypass. The system should be installed in a manner that will allow future removal/repair in live flow conditions without system bypass.
Lastly, the Raceway Pump Station Emergency Overflow Basin Improvements project (CIP 8321) addresses groundwater, or other water sources entering the emergency overflow basin at the Raceway Pump Station which is reducing storage volume and potential vector control issues. The main objectives are to eliminate and/or reduce the source of groundwater with a subdrain system, utilize injection grouting if necessary to seal cracks in the basin, and reseal the overflow basin with an appropriate lining method.
The City and District have decided to utilize the progressive design -build delivery (PDB) model to complete these projects. By using the collaborative PDB delivery model, the intent is to complete the scope within the available budget, leverage prior work products, and streamline schedule to complete project and minimize time under bypass conditions.
The project includes services required of the progressive DB include those during Pre - Construction and Construction, and Operations/Start-up of the Project.

Section 16: Project Completion
16.1 Substantial Completion shall be that stage in the progress of the construction when all Work on the Project is sufficiently complete in accordance with the Construction Documents so that City can fully utilize entire Project; Substantial Completion shall further mean that all goods, services and systems to be provided under the terms and conditions of the Construction Documents are in place and have been initially tested, and are operationally functional, subject only to final testing, balancing and adjustments and normal Final Completion punch list Work.
16.2 Final Completion shall be deemed to occur on the last of the following events: (1) recordation of a Notice of Completion for the Project; (2) acceptance of the Project by the City; (3) issuance of a final Certificate of Occupancy for the Project; (4) submission of all documents required to be supplied by DB to City under this Agreement, including but not limited to As -Built Drawings, warranties, and operating manuals; (5) and delivery to City of a Certificate of Completion duly verified by DB.

09/23/2025
C5 Page 202 of 1112
Design / Build Services Agreement
Project (CIP No. XXX)
17.4 Further, an extension in Contract Time will not be granted unless DB can demonstrate through an analysis of the Project Schedule that the increases in the time to perform or complete the Project, or specified part of the Project, beyond the corresponding Contract Time arise from unforeseeable causes beyond the control and without the fault or negligence of DB, its Design Consultants, and subcontractors or suppliers, and that such causes in fact lead to performance or completion of the Project, or specified part in question, beyond the corresponding Contract Time, despite DB's reasonable and diligent actions to guard against those effects.
17.5 DB carries the burden of proving an entitlement to an increase in the Contract Time.
Delays attributable to and within the control of Design Support Consultants, or subcontractor or supplier shall be deemed to be delays within the control of DB. No time extension will be allowed for such delays. An increase in Contract Time does not necessarily mean that DB is due an increase in the GMP.
Section 18: Late Completion
18.1 City and DB recognize that time is of the essence in this Agreement and that City will suffer financial loss if the Project is not completed within the Contract Time, plus any extensions thereof allowed in accordance with Section 17.3. They also recognize the delays, expense, and difficulties involved in proving in a legal proceeding the actual loss suffered by City if the Project is not completed on time. Accordingly, instead of requiring any such proof, City and DB agree that DB shall pay as liquidated damages (but not as a penalty) for each calendar day of delay beyond the time specified for Substantial Completion of the Project, the following amounts which DB expressly agrees are "not unreasonable under the circumstances" as defined in California Civil Code §1671(b): $4000 for each calendar day. Liquidated Damages shall not be assessed after the date on which Substantial Completion is achieved pursuant to Section 16.
Section 19: Right to Modify Work

Upon receipt of any such document, DB shall promptly proceed with the Work involved which will be performed under the applicable conditions of the Construction Documents (except as otherwise specifically provided).
19.2 When City desires a change in the Project, City may issue a Request for Proposal to DB.
DB will be required to respond within the time indicated by City.
Section 20: INTENTIONALLY LEFT BLANK.
Section 21: Work By Others
21.1 City may perform other work related to the Project at the Project Site by City's own forces, or let other direct contracts ("City Contractor"). The City will give DB reasonable notice of its intent to do such other work. DB's work shall take priority over the City Contractors; but the Parties will use their best efforts to coordinate their work so as to minimize the disruption to each other's work and to allow City Contractor to proceed expeditiously.
21.2 If the proper execution or results of any part of DB's work depends upon the work by the City or City Contractor, DB shall promptly inspect and report to City in writing any apparent delays, defects, or deficiencies in the City's work that render it unavailable or unsuitable for such proper execution and results. DB's failure to promptly report such delays, defects, or deficiencies in 00105692 I

21.3 If DB or any person or entity working for DB causes damage to the City's or City Contractor's work, property, or person, or if any claim arising out of DB's performance of the Project by any other contractor is made against DB, by City, any other contractor, or any other person, DB shall promptly repair and/or resolve said claim at no cost to City.
Section 22: Warranties and Guarantees
22.1 DB warrants and guarantees to City that materials and equipment incorporated into the Project will be new unless otherwise specified and that all work will be in strict accordance with the Construction Documents and will not be defective. Prompt notice of defects known to City shall be given to DB. All Defective Work, whether or not in place, may be rejected, corrected, or accepted as reasonably directed by City, provided DB shall not be entitled to an extension in Contract Time or increase in GMP because of any delay or increase in cost attributable to the rejection, correction or acceptance of said work. Defective work may be rejected even if approved by prior inspection.
22.2 The warranty period shall commence when the Certificate of Final Completion is issued or at beneficial use by City prior to Final Completion, whichever occurs earlier, and extend one (1) year after that date or whatever longer period may be prescribed by laws or regulations or by the terms of any applicable special guarantee or specific provision of the Construction Documents.
22.3 INTENTIONALLY LEFT BLANK.

22.5 Correction of Defective Work - If within the designated warranty period, or such longer period as may be required by laws or regulations, the Project or any part of the Project, is discovered to contain defective work, DB shall promptly, without any reimbursement or adjustment in the GMP, and in accordance with City's written instructions, either correct that defective work, or if it has been rejected by City remove it from the Project and replace it with work which is not defective. If circumstances warrant it, including but not limited to, in an emergency, City or DB may have the defective work corrected or the defective work removed and replaced. In that event, DB shall not be allowed to recover any associated costs, and DB shall reimburse City for all direct, and indirect costs of City, and City shall be entitled to an appropriate decrease in the GMP, to withhold a setoff against amount recommended for payment, or make a claim on DB's bond if DB has been paid in full.
22.6 With respect to all warranties, express or implied, from subcontractors, manufacturers, or suppliers for Work performed and materials furnished under this Agreement, the DB shall:

Before taking possession of or using any Work, City shall furnish DB a list of items of Work remaining to be performed or corrected on those portions of the Work that City intends to take possession of or use. However, failure of City to list any item of Work shall not relieve DB of responsibility for complying with the terms of this Agreement. City's possession or use shall not be deemed an acceptance of any Work under this Agreement, nor relieve the DB of any of its obligations under this Agreement.
23.2 While City has such possession or use, DB shall be relieved of the responsibility for the loss of or damage to the Work resulting from City's possession or use. If prior possession or use by City delays the progress of the Work or causes additional expense to DB, an equitable adjustment shall be made in the GMP or the Contract Time, and the Agreement shall be modified in writing accordingly.
Section 24: Personal Services and Non -Assignability
24.1 This is a personal services Agreement and, therefore, DB shall not alter the key employees or Design Consultants nor assign or transfer, voluntarily or involuntarily, any of its rights, duties or obligations under this Agreement except upon the prior written consent of City.

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum OR Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services Executive Summary
This report is submitted to provide an alternative analysis of fats, oils, and grease (FOG) mitigation technologies for the Raceway Basin Pump Station (RBPS) and Buena Creek Pump Station (BCPS) Improvements Study and Owner's Advisor Services Project (project). Historically, these sewage pump stations have been experiencing consistent and significant levels of FOG build up in the wet wells, and rags clogging pumps at the BCPS. The purpose of this report is to provide FOG and ragging abatement design recommendations for construction that would improve the benefits and cost for these issues.
The project is located in the City of Vista at the RBPS and BCPS. The RBPS is owned by the City of Vista (City), and the BCPS is owned by Buena Sanitation District (BSD) and managed by the City.
Both pump stations are operated and maintained by the Encina Wastewater Authority. Each pump station conveys wastewater for treatment at the Encina Water Pollution Control Facility (EWPCF) in Carlsbad, and the pump stations are described below.
The BCPS was built in 2002. The pump station has a design capacity of 8.8 million gallons per day (mgd) and an average daily flow of 2.1 mgd. Influent wastewater enters the pump station through dual 24 -inch pipelines. Before entering the wet well, influent water passes through parallel channel grinders.
Effluent water leaves the pump station through a 24 -inch ductile iron pipeline that connects to an 18 -inch polyvinyl chloride (PVC) force main. This force main ultimately joins BSD's force main to the EWPCF.
The City owns the RBPS. In 2007, the facility was replaced with the current facility, which has a design flow of 1.9 mgd. The current average daily wastewater influent flow is approximately 0.5 mgd.
Encina Wastewater Authority (EWA) provides operational, maintenance, and administrative contract support services under a Memorandum of Understanding (MOU) agreement with the City. RBPS and BCPS are considered critical infrastructure to the City' s sanitary sewer system.
Both pump stations are experiencing severe FOG accumulation. The operation and maintenance (O&M) staff are spending up to 8 hours per week breaking down the FOG build up in the wet wells.
Staff use water hoses to break down the FOG mat in the wet well to their best of abilities. In addition, O&M staff have reported a surge in ragging at BCPS due to COVID-19. A site visit to the pump stations was conducted on March 11, 2021, to observe the FOG conditions, witness operator's effort to breakdown the FOG mats, and discuss the current means of FOG mitigation with operators. Field notes from that visit are included in Appendix A
FOG is always present in wastewater. The issues start when the FOG buildup in the sewer lines, manholes, and pump station wet wells. The FOG buildup within a pump station wet well can impact the wet well working volume, malfunctioning of pumps, cause odor problems, increase maintenance costs, increase the presence of wanted and potentially disease causing/spreading vectors, and escalate the potential of sanitary sewer overflow. There is a variety of options available for FOG abatement at pump stations, from structural modifications to the wet well, controlling and removal using wet well operating levels, mechanical equipment, chemical, and/or biological additives.
For both RBPS and BCPS invasive structural modifications may not be a viable option as it may be more cost intensive and may not provide the anticipated benefits in reducing O&M time.
Several technologies are available and have been successfully used at other wastewater collection and treatment facilities to alleviate the FOG problem. HDR considered the following six types of 09/23/2025

To evaluate these technologies on an equal basis, HDR developed a set of 11 criteria relevant to the FOG abatement under consideration for a cost benefit analysis (CBA). The evaluation criteria with their scoring values were discussed in a CBA Evaluation Criteria Technical Memorandum (Appendix C), which was submitted and accepted by the City and are included in Table ES -2.

The six types of technology alternatives briefly were evaluated based on these 11 criteria and information collected from the manufacturer for each. Manufacturers were chosen based on HDR's experience, familiarity, and initial assumption that they are efficient, and viable options. References provided by each of the manufacturers were contacted via phone calls and/or followed up with email correspondences so that they could participate in an independent survey questionnaire developed by HDR regarding their experience with their equipment. Survey results are included in Appendix D.
For comparison purpose, a no action alternative was also evaluated. The no action option was based on the current practice of manually breaking the FOG mats at the pump stations with water hose on a weekly basis. This no action option is also used as a baseline comparison for determining when the investment of a new technology breaks even.
Anue's EnviroPrep® (EP) Well -Washers Systems condition wastewater to provide ongoing lift station maintenance. The EP system recycles discharged wastewater through the system and agitates the surface when returning it back to the well, automating lift station FOG maintenance.
Flygt mechanical submersible mixers are typically used to create turbulence in clarifiers at wastewater treatment plants and in the high -sediment wastewater chain of industrial facilities. However, Flygt has a mixer, Model 4630, to prevent FOG buildup in the wet well of a lift station. The Model 4630 delivers a powerful 103 pound -force of thrust. Flygt designed the unit with a cutter behind the 6 -degree propeller that prevents stringy fibrous material from building up. A basic timer is set for the mixer to run for several minutes at half-hour intervals. The mixer is placed at the bottom of the wet well on a leveled surfaced and pointed upwards for lift station FOG mitigation.
MicroBlockTM is a solid, bacterial laden, slow release bioblock for use in degrading FOG in lift stations, organic waste grease traps, and at various areas upstream from the waste treatment system. The bioblock is hung inside the wet wells and is allowed to gradually dissolve over a 30- to 90 -day period, which theoretically allows for continuous treatment and degradation of waste by degrading the grease and organics at the source. The bacteria may also build up a minor slime coating in the pipes downstream that helps keep grease from building up in the pipes.
Pulsed Hydraulics, Inc. (PHi) has a mixing device that operates on compressed air. The PHi mixing system consists of three basic component groups: air compressor to supply air, a sequencing computer (control panel), and hydro -pulse bubble forming plate (BFP). Compressed air is supplied through a compressor creating the source of the hydro -pulse bubble which mixes the contents of the tank. The sequencing computer manages the parameters and schedule of the release of the bubble controlling the bubble -pulse intensity, duration, interval between pulses, and pulsing sequence between different forming plates or groups of forming plates in a tank. Forming plates are constructed from various materials to fit the specific application and are designed to form a hydro -pulse, a massive air bubble which creates the mixing hydraulics starting from the bottom to the top of the tank. When 09/23/2025
C5 Page 2.21920to1i1 i12
Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services the bubble from the plate begins its ascent, it presses liquids and solids above it upward, and draws liquid and sediment along from beneath. As it continues to rise, liquid and solids in its path are put into motion upward. When the bubble breaks on the surface, the liquid and solids move tangentially to the surface, producing a surface mixing motion that moves to the tank wall and then down the sides to the bottom, completing the mixing cycle.
The VapexTM system, with its patented air atomizing three -fluid nozzles, enhances the advanced oxidation process by creating hydroxyl radicals, an oxidant typically used in odor treatment. The nozzle combines ozone, water, and air to create hydroxyl radical mist that is efficiently dispersed throughout enclosed or partially enclosed spaces, such as lift stations, wet wells, holding tanks, diversion boxes, and headworks channels. VapexTM technology remediates FOG by breaking the double carbon bonds that form the fatty acid chain. By breaking the carbon bonds, FOG does not reform downstream. Odors from volatile fatty acids are decreased significantly. Continuous treatment reduces fats, oils, and grease from collecting on the surface of the process water and walls, reducing or eliminating the need to remove and dispose of surface FOG.
The Vaughan Conditioning Pump TM is a Vaughan Submersible Chopper Pump mounted on a portable stand and fitted with high -velocity mixing nozzle. The conditioning pump recirculates the contents of the wet well, chopping and mixing to produce a homogeneous mixture that is more easily pumped out.
Floating mats are removed and solids that have accumulated on the floor are resuspended. As the pump is mounted on a portable stand, it can easily be used in multiple applications at a single jobsite, facility, or municipality.
The six FOG mitigation alternatives were evaluated, each assumed capable of meeting the needs of the BCPS and RBPS. Table ES -3 and Table ES -4 are summary comparison tables of the different technologies for BCPS and RBPS.

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum OR Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services The maintenance requirements for all alternatives varies based on type and application per pump station. The maintenance requirements for each FOG mitigation alternative was based on manufacturer -provided information and contact references. As previously discussed, several equipment replacements were included periodically.
A present worth analysis was conducted for each alternative in order compare each technology cost holistically. This was completed by assessing the total cost of the technology over a 20 -year life cycle, which includes initial capital costs, maintenance costs, and operating cost. The net present value of the 20 -year life -cycle cost for the FOG mitigation alternatives considered both capital and O&M costs in 2021 dollars.
The energy cost was incorporated into the life -cycle costs at power rates of $0.285 per kilowatt-hour and $0.353 per kilowatt-hour for BCPS and RBPS, respectively. Capital costs were included to complete the installation of each alternative with any additional significant equipment or modification required. Details of the construction costs are included in Appendix E. The construction cost estimate included additional markup costs as a percentage of direct costs as presented. The O&M cost includes water usage cost, spare parts, labor hours, vendor support, and most importantly, equipment or motor overhauls during a 20 -year cycle. Section 4.8 lists maintenance items and their frequency identified during equipment review and reference interviews. Assumed operating hours were provided as a range from each manufacturer and conservative usage was assumed for costs.
The results of the life -cycle cost analysis and other costs associated with the FOG mitigation alternatives for BCPS and RBPS are shown in Table ES -5 and Table ES -6, respectively.

The no action alternative was considered in this CBA as a baseline comparison for the proposed technologies. The data was computed in a spreadsheet, and the technologies are ranked in a descending order in Section 6. Scoring was performed for each lift station and similar score were obtained.
Reference track record score were based on the feedback received from references. Flygt, PHi, and Vaughan received positive feedback from its current clients. Constructability scoring was based on how much additional construction costs were needed to install the alternative. All alternatives require some level of modification to the existing lift stations except MicroBlock, which has the highest score.
Anue and PHi have the highest scores for ease of operation because of how simple it is to operate their systems to mitigate FOG relative to the other alternatives. MicroBlock virtually requires the same amount of daily/weekly maintenance already required in a no action scenario. Only Vapex requires a constant feed of potable water for its system, although it is not a significant amount. PHi may have the only impact on odor control because of the additional air added to the wet wells. The City should consider the potential impacts on downstream processes that may be caused by the MicroBlock technology. As previously discussed, no references were provided to be able to confirm MicroBlock's performance. Capital and O&M costs are a quantifiable comparison based on the 20 -year life -cycle analyses conducted for all the alternatives. Flygt, MicroBlock, PHi, and Vaughan have the lowest capital and O&M costs. Vapex and PHi may provide some additional supplementary benefits, such as odor control for Vapex and rag mitigation for PHi. PHi can suspend rags in the wet well, which would allow for clumps of rag to be minimized and allow the lift station to pump out a lower rate of rags during operation.

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum OR Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services For the types of FOG mitigation equipment considered in the lift stations, the Flygt, PHI, and Vaughan systems had the lowest life -cycle cost and highest CBA scores compared to the other three alternatives. MicroBlock is an unknown technology and had the highest O&M costs. The Anue and Vapex systems had the highest capital cost and the highest energy costs. Flygt, PHi, and Vaughan all have a break-even point of less than 10 years, except for PHi at the RBPS. However, consideration should still be taken for PHi, since it is suitable for BCPS and would minimize additional staff training by having the same equipment throughout.
Based on our analysis, the top three recommended options for FOG mitigation at BCPS are:
• PHi (Models PHi 350-2/3, BFP, and Kaeser SK Compressor); • Flygt (Model SR -4640 Submersible Mixer); and
• Vaughan (Models S4TC-103 and S6UC-113).
Based on our analysis, the top three recommended options for FOG mitigation at RBPS:
• PHi (Model PHi 350-2, BFP, and Kaeser SM Compressor); • Flygt (Model SR -4640 Submersible Mixer); and
• Vaughan (Model S4SC-095).

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum I.)� Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services 1 Introduction
This report provides an alternative analysis of FOG mitigation technologies for the RBPS and BCPS.
Historically, these sewage pump stations have been experiencing consistent and significant levels of FOG buildup in the wet wells and rags clogging pumps at the BCPS. The purpose of this report is to provide FOG and ragging abatement design recommendations for construction that would improve the benefits and lower cost for these issues.
1.1 Background
The project is within the City at the RBPS, located at 2685 South Melrose, Vista, California 92081, and BCPS located at 2080 South Melrose, Vista, California 92081. The RBPS is owned by the City, and the BCPS is owned by BSD and managed by the City. Both pump stations are operated and maintained by the Encina Wastewater Authority. Each pump station conveys wastewater for treatment at the EWPCF in Carlsbad, and the pump stations are described in Section 2. 09/23/2025

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services 2 Existing Pump Stations and Fats, Oils, and
Grease Issue
2.1 Buena Creek Pump Station
The BCPS was built in 2002. The pump station has a design capacity of 8.8 mgd and an average daily flow of 2.1 mgd. Influent wastewater enters the pump station through dual 24 -inch pipelines. Before entering the wet well, influent passes through parallel channel grinders. Effluent water leaves the pump station through a 24 -inch ductile iron pipeline that connects to an 18 -inch PVC force main. This force main ultimately joins BSD's force main to the EWPCF. Figure 2-1 shows the site plan of the existing facility.
The wet well is divided into two sections, which can be isolated by a slide gate for maintenance without impeding operations. A programable logic controller monitors the wet well level using level sensors and controls with dedicated pump variable frequency drives to maintain a level setpoint. Under normal conditions, one sewage pump handles daily diurnal flow. Two pumps are only used during high influent flow events (rain) or if the lead pump is impacted by rags.
The pump station currently directs all flow to the EWPCF through the Buena force main; however, it can convey flow to the Shadowridge Water Reclamation Facility through the Encina force main.
Although the Shadowridge Water Reclamation Facility was shut down in 2003, flows can be sent there for emergency storage or during maintenance.
A valve at Pump Number 1 allows flow to be manually diverted to either the EWPCF or to Shadowridge Water Reclamation Facility. Pump Numbers 2 and 3 then send flow to either facility using motorized discharge valve actuators. Pump Numbers 4 and 5 pump flow to the EWPCF. Pump Number 5 is used mainly for FOG removal activities. Pumps Number 1 through 4 are rotated frequently into and out of the lead pump position. The abandoned Shadowridge Water Reclamation Facility pump vault provides emergency storage. The vault is made of unlined concrete and has a capacity of 95,000 gallons.
Additional overflow storage is provided by topography that directs flow away from the adjacent creek and into a natural depression.
An emergency standby generator supplies power to the pump station during a commercial power failure. A biofilter that removes hydrogen sulfide from the wet well exhaust provides vapor phase odor control. A surge protection system protects the Encina force main against water hammer (Carollo 2016).

2.2 Raceway Basin Pump Station
The City of Vista owns the RBPS. In 2007, the facility was replaced with the current facility, which has a design flow of 1.9 mgd. The current average daily wastewater influent flow is approximately 0.5 mgd.
Influent flow enters the pump station through a 12 -inch PVC gravity main. Upon arrival, the flow either passes through a primary channel grinder or is diverted to a redundant grinder. Wastewater must spill over a short weir wall to flow to the redundant grinder. Grinders do not operate as lead/ lag but rather as primary and backup (duty/standby). The grinders help to remove debris from the wastewater to prevent it from entering the wet well and damaging downstream equipment.
Effluent leaves the pump station through an 8 -inch PVC force main, which connects to the BSD's force main to the EWPCF. Figure 2-2 shows the site plan of the existing pump station.
One of three submersible pumps handle influent flow at the RBPS. Each pump operates in a lead, lag, or standby configuration to adjust to variations in flow. A programable logic controller controls dedicated variable frequency drives to operate the pumps to maintain a wet well level setpoint of 60 inches.
The operating volume of the wet well is approximately 5,400 gallons. An overflow storage pond provides 156,000 gallons of emergency storage on site. During power failure, the pump station has one standby generator to ensure continuity (Carollo 2016). A carbon scrubber provides vapor phase odor control to minimize impact to neighboring businesses, even though sulfide levels at the inlet are typically present, they are typically below the permitted influent concentration level of 9 ppmv. 0962,3,6212125

Operation and routine maintenance for BCPS and RBPS are conducted by the Encina Wastewater Authority under agreement with City of Vista. RBPS and BCPS are considered critical infrastructure to the City's sanitary sewer system.
Both pump stations are experiencing severe FOG accumulation. The O&M staff are spending up to 8 hours per week breaking down the FOG buildup in the wet wells. Staff use water hoses to break down the FOG mat in the wet well to their best of abilities, as shown on Figure 2-3 and Figure 2-4 for BCPS and RBPS, respectively. In addition, O&M staff reported a surge in ragging at BCPS during COVID-1 9.

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum I.)R Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services An additional 8 hours are spent every week manually removing rag balls from the influent pump volutes at BCPS. FOG builds up along with ragging, can impact the pumps, pipes and instrumentation and potentially cause an overflow or even sewage spill if not mitigated.
The O&M staff have done a tremendous job to prevent a sanitary sewer overflow at either pump station. Both pump stations are located near creeks, and a sanitary sewer overflow to either creek would have significant environmental and public health impact.
A site visit to the pump stations was conducted on March 11, 2021, to observe the FOG conditions, witness operator's effort to breakdown the FOG mats, and discuss the current means of FOG mitigation with operators. Field notes from that visit are included in Appendix A. 09/23/2025

Evaluation
3.1 Fats, Oils, and Grease Mitigation Technologies
FOG is always present in wastewater. The issues start when the FOG builds up in the sewer lines, manholes, and pump station wet wells. The FOG buildup within a pump station wet well can impact the wet well working volume, malfunctioning of pumps, cause odor problems, increase maintenance costs, and escalate the potential of sanitary sewer overflow. There are a variety of options available for FOG abatement at pump stations, from structural modifications to the wet well to controlling and removal using wet well operating levels, mechanical equipment, chemical, and/or biological additives.
For both the RBPS and BCPS, invasive structural modifications may not be a viable option as it may be more cost intensive and may not provide the anticipated benefits in reducing O&M time.
Several technologies are available and have been successfully used at other wastewater collection and treatment facilities to alleviate the FOG problem. HDR considered the six technologies presented in Table 3-1 to be used at both RBPS and BCPS. Product sheets for these FOG mitigation technologies are included in Appendix B.

3.2 Evaluation Criteria
To evaluate these technologies on an equal basis, HDR developed a set of 11 criteria relevant to the FOG abatement under consideration. The evaluation criteria, along with their scoring values, were discussed in a CBA Evaluation Criteria Technical Memorandum, which was submitted and accepted by the City of Vista. The Cost Benefit Technical Memorandum is included in Appendix C. A list of the evaluation criteria is also included in Table 3-2. Each criterion is scored on a scale of 0 to 5, with 5 being the best score. The evaluation scores are tabulated in a spreadsheet. A weighting factor was then applied to each score, which is also listed in Table 3-2. The weighting factors range from 1 to 10 and are applied to criterion based on the impact and the importance of the criterion on the evaluation. 09/23/2025
C5 Page 24,7y 04212112
Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services The criterion weight is multiplied by the corresponding criterion score to arrive at the final score for each criterion. The scores are then added together to arrive at the total score for each technology.
The technologies are then ranked from highest to lowest based on the scores.

The six types of technology alternatives described in Section 3.1 were evaluated based on the 11 criteria described in Section 3.2 and information collected from the manufacturer for each technology. Manufacturers were chosen based on HDR's experience, familiarity, and initial assessment that they are efficient and viable options. Each manufacturer generally represents the type of technology capable of FOG mitigation, with nuances between each type of manufacturer not considered in this report.
Data was collected from each manufacturer in order to develop the scores for the 11 criteria. The data request from each manufacturer consisted of the following eight items:
• Scope of supply and work specific to RBPS and BCPS
• Budgetary equipment cost
• Equipment brochures or fact sheets that present general operations • Limitations and functionality
• Maintenance requirement
• Five references in the United States, preferably in Southern California • Local manufacturer representative contact information 09I2 h2,Q25
C5 Page 248 of 1112
Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum I.)R Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services • Solicitations for introduction presentations to their equipment These data requests were customized for the needs, features, and size limitations at RBPS and BCPS based on information provided, such as -built information, equipment materials, etc.
The scope of work and budgetary estimates were used to develop construction costs for each alternative. O&M information provided by manufacturers was used to develop for long-term costs in a 20 -year life -cycle cost analysis; details are discussed in Section 5.1.2. References provided by the manufacturers were contacted via phone calls and/or followed up with email correspondences so that they could participate in an independent survey questionnaire developed by HDR regarding their experience with their equipment. Survey results are included in Appendix D. However, not all references responded to our survey participation request.
Brown bag presentations were requested from the unconventional and unique technologies, such as Anue, PHi, and Vapex, and were delivered virtually to introduce City staff to these technologies and ask relevant questions.

Alternatives
Product data sheets for all alternatives are included in Appendix A. The details of these technologies will be discussed in the following sections.
For comparison purpose, a no -cost option was also evaluated. The no -cost option was based on the current practice of manually breaking the FOG mats at the pump stations with water hose on a weekly basis. This no -cost option is also used as a baseline comparison for determining when the break-even cost of the investment of a new technology would be reached.
4.1 Anue EnviroPrep®
4.1.1 Description
Anue's EP Well -Washers Systems condition wastewater to provide ongoing lift station maintenance.
The EP System recycles discharged wastewater through the system and agitates the surface when returning it back to the well, automating lift station FOG maintenance. Figure 4-1 illustrates the EP installation options for a wet well in which either the discharge main can be tapped to recirculate wastewater through the rotating head assembly or use a dedicate pump to recirculate wastewater.
This process eliminates the need for vacuum trucks or manual clean out as it breaks up FOG (Anue Water Technologies 2017). An example installation for a wet well is included on Figure 4-2. The installation shown in Figure 4-2 is for demonstration installation and does not represent a final system installation. A more robust support system and rotating head quick -connect would be included in the design of this system.
Maintenance service for this system does not require pump station shutdown, however it does require the system's pumps to be shutdown. Isolation valves can be added to the pumping system. Confined space entry is not required to service the pumps as they are installed with guide rails. However, it may be required for the rotating heads if maintenance staff cannot disconnect the rotating heads and pull above the wet well.

4.1.2 Anue References Check
HDR made several attempts of contacting the two references provided by the manufacturer, but HDR was unable to verify the performance or receive input on issues for this type of system. However, one reference for another system installation indicated that their experience with Anue systems, before changing to their new FOG mitigation system, was negative as the performance was unreliable and did not achieve satisfactory FOG mitigation for their multiple lift station installations. Survey questionnaires are listed in Appendix A.
4.1.3 Proposed Anue System — Buena Creek Pump Station
The proposed system for BCPS is comprised of five 1.5 -inch composite rotating head assemblies with wall mount brackets, feed masts, and three high-pressure discharge hoses for the well cleaning system. Feeding the rotating heads are three submersible grinder pumps in the wet well, two are sized at 7.5 horsepower, and one at 5.0 horsepower. Two pump panels are required for pump control. The system data sheet is listed in Appendix B.
4.1.4 Proposed Anue System — Raceway Basin Pump Station The proposed system for the RBPS is comprised of two 1.5 -inch composite rotating head assemblies with wall mount brackets, feed masts, and one high-pressure discharge hose for the well cleaning system. Feeding the rotating heads is one submersible grinder pump in the wet well, sized at
7.5 horsepower. One pump panel is required for pump control. 09/23/2025

4.2 Flygt Submersible Mixer
4.2.1 Description
Flygt mechanical submersible mixers are typically used to create turbulence in clarifiers at wastewater treatment plants and in the high -sediment wastewater chain of industrial facilities. However, Flygt has a mixer (Model 4630) to prevent FOG buildup in the wet well of a lift station, see Figure 4-4 for a cross section of this model and its design components.
The Model 4630 delivers a powerful 103 pound -force of thrust. Flygt designed the unit with a cutter behind the 6 -degree propeller that prevents stringy fibrous material from building up. A basic timer is set for the mixer to run for several minutes at half-hour intervals. The mixer is placed at the bottom of the wet well on an adjustable platform to account for sloped surfaces and pointed upwards for lift station FOG mitigation, as illustrated on Figure 4-5 (Xlyem 2021).

OPTIMUM GREASE SCUM AND CRUST EROSION.
4.2.2 Flygt References Check
After contacting five of the references provided by the manufacturer, HDR verified the issues arising from these mixers were generally consistent with what Flygt reported. Installation references stated that motor overhauls were required every 5 years. For those instances, the mixer is generally sent to the manufacturer's factory for motor overhaul. To be conservative, a motor overhaul estimate was included at Years 5, 10, 15, and 20 in the 20 -year life -cycle cost. A rental mixer may be required or accounted for with a redundant standby mixer. Many references indicated that they have not had issues with the mixers once they are up and running and performance is satisfactory. Survey questionnaire results are included in Appendix A.
4.2.3 Proposed Flygt System — Buena Creek Pump Station
The proposed system for BCPS is comprised of three Flygt Model SR -4640 submersible mixers, stainless steel, with a 4 -horsepower motor, stands, start-up, chain, and motor relays. An adjustable sloped platform would be used to provide a leveled installation. The system data sheet is listed in Appendix B. Mixers would operate while lift station pumps are off to avoid air entrainment into the pumps

4.2.4 Proposed Flygt System — Raceway Basin Pump Station The proposed system for the RBPS is comprised of one Flygt Model SR -4640 submersible mixer, stainless steel, with a 4 -horsepower motor, stands, start-up, chain, and motor relays. An adjustable sloped platform would be used to provide a leveled installation. The system data sheet is listed in Appendix B. Mixers would operate while lift station pumps are off duty to avoid air entrainment into the sewage pumps.
4.3 MicroBlock Biological Additive
4.3.1 Description
MicroBlockTM is a solid, bacterial laden, slow release bioblock for use in degrading FOG in lift stations, organic waste grease traps and at various areas upstream from the waste treatment system. The bioblock is hung inside the wet wells and is allowed to gradually dissolve over a 30- to 90 -day period, which theoretically allows for continuous treatment and degradation of waste by degrading the grease and organics at the source. Figure 2-1 shows MicroBlock's technology in 2 -pound and 10 -pound blocks. The bacteria may also build up a minor slime coating in the pipes downstream that helps keep grease from building up in the pipes. The biofilm will eventually dissipate once the use of the MicroBlock is discontinued.
Because of the diversity of the microorganism systems incorporated into this product it is specifically developed for use in municipalities, industries, and food processing plants for which there requires a particular high impact on FOG (Environmental Leverage, Inc. 2003).

4.3.3 Proposed MicroBlock System — Buena Creek Pump Station The proposed system for BCPS consists of 10 -pound MicroBlock blocks that are required for each wet well and need to be replenished monthly.
4.3.4 Proposed MicroBlock System — Raceway Basin Pump Station The proposed system for the RBPS consists of a 2 -pound MicroBlock block that requires replenishing monthly.
4.4 Pulsed Hydraulics, Inc.
4.4.1 Description
PHi has a mixing device that operates on compressed air. The PHi mixing system consists of three basic component groups: air compressor to supply air, a sequencing computer (control panel), and hydro -pulse BFP.
Compressed air is supplied through a compressor creating the source of the hydro -pulse bubble which mixes the contents of the tank. The sequencing computer manages the parameters and schedule of the release of the bubble, controlling the bubble -pulse intensity, duration, interval between pulses, and pulsing sequence between different forming plates or groups of forming plates in a tank. The details and panel interior is shown on Figure 4-7. Forming plates are constructed from various materials to fit the specific application and are designed to form a hydro -pulse, a massive air bubble, which creates the mixing hydraulics starting from the bottom to the top of the tank. When the bubble from the plate begins its ascent, it presses liquids and solids above it upward and draws liquid and sediment along from beneath. As it continues to rise, liquid and solids in its path are put into motion upward. When the bubble breaks on the surface, the liquid and solids move tangentially to the surface, producing a surface mixing motion that moves to the tank wall and then down the sides to the bottom, completing the mixing cycle.
New compressors in the state of California require pressure vessel permit to operate (Department of Industrial Relations). Per CCR 461 (h), air tank with pressure less than 150 psi and volume less than 25 cu. ft (187 gal) only requires initial inspection at time of installation and will be issued an infinite operating permit. The proposed compressed air vessel at BCPS is 92.5 gallons and at RBPS is 71 gallons and both operate at 125 psi. Permitting would be further addressed in the design phase. 09/23/2025

HDR contacted the four references provided by the manufacturer and found no issues associated with this mixing system. Many references indicated that performance is satisfactory. Survey results are included in Appendix D.
4.4.3 Proposed Pulsed Hydraulics, Inc. System — Buena Creek Pump Station
The proposed system for BCPS is comprised of five BFP, three on the larger wet well side and two on the other wet well side as shown on
Figure 4-8 and Figure 4-9. The BFP consists of two disks separated approximately 3/8 inch apart by internal spacers. The BFPs are 8 -inch diameter, 316 stainless steel disks. Air is injected through a 1 -inch national pipe thread threaded nipple in the top disk to the space between the disks, where it is forced laterally to form the mixing air mass. Three 3/8 -inch diameter, equally spaced predrilled holes are used for anchoring the BFP to the tank bottom.
Additionally, two PHi mixing valve enclosures will be supplied along with injection valves, which are solenoid controlled and pilot air assisted. Refer to the manufacturer product sheets in Appendix B for complete system details.
A station bypass would need to be considered for mounting the BFP on the west wet well. Further construction sequencing would be addressed in the design phase and in coordination with Vista and EWA.

4.5 Vapex Oxidation System
4.5.1 Description
The VapexTM system (illustrated on Figure 4-11) with its patented air atomizing three -fluid nozzles enhances the advanced oxidation process by creating hydroxyl radicals, an oxidant typically used in odor treatment.
The nozzle combines ozone, water, and air to create a hydroxyl radical mist that is efficiently dispersed throughout enclosed, or partially enclosed, spaces, such as lift stations, wet wells, holding tanks, diversion boxes, and headworks channels. Figure 4-12 presents the patented nozzle.
VapexTM technology remediates FOG by breaking the double carbon bonds that form the fatty acid chain. By breaking the carbon bonds, FOG does not reform downstream. Odors from volatile fatty acids are decreased significantly. Continuous treatment reduces FOG from collecting on the surface of the process water and walls, reducing or eliminating the need to remove and dispose of surface FOG.
The oxidative process eliminates biofilm on surfaces that lead to costly infrastructure corrosion.
Surface pH in wet wells can be as low as 1; however, the powerful oxidant fog covers the entire surface, killing the bacteria that metabolize hydrogen sulfide to sulfuric acid, raising the pH above 6 and preserving the infrastructure (Vapex Environmental 2021).

4.5.2 Vapex References Check
After contacting five of the references provided by the manufacturer, HDR verified the issues arising from this system was generally consistent with what Vapex reported. Several installations stated that the nozzles constantly plugged and required maintenance between 2-4 hours weekly. Additionally, a contact reference indicated that the rotameters are sensitive to clogging as well. Furthermore, one reference stated that a unit's touch pad was unresponsive, and replacements were needed at start-up, or soon after, but still within the warranty period; Vapex upheld its warranty. Survey results are included in Appendix A.
4.5.3 Proposed Vapex System — Buena Creek Pump Station
The proposed Vapex system for BCPS consists of one Nano cabinet unit, two HV-500 nozzles, oxidant tubing, water tubing, cable sheath, controls and communications, and monitoring support. Data sheets listed in Appendix B.
4.5.4 Proposed System — Raceway Basin Pump Station
The proposed Vapex system for the RBPS consists of the same scope as Buena Creek. The proposed Vapex system consists of one Nano cabinet unit, two HV 500 nozzles, oxidant tubing, water tubing, cable sheath, controls and communications, and monitoring support.
4.6 Vaughan Conditioning Chopper Pumps
4.6.1 Description
The Vaughan Conditioning Pump TM is a Vaughan Submersible Chopper Pump mounted on a portable stand and fitted with high -velocity mixing nozzle, a model of this pump is shown on Figure 4-13. The conditioning pump recirculates the contents of the wet well, chopping and mixing to produce a homogeneous mixture that is more easily pumped out. Floating mats are removed, and solids that have accumulated on the floor are resuspended. As the pump is mounted on a portable stand it can easily be used in multiple applications at a single jobsite, facility, or municipality (Vaughan 2021).

Fats, Oils, and Grease Mitigation Recommendation Technical Memorandum I.)R Raceway Basin and Buena Creek Pump Stations Improvement Study and Owner's Advisor Services 5 Cost Benefit Analysis
The FOG mitigation technology alternatives were scored based on the evaluation criteria described in Section 3 for a CBA. The no action alternative was considered in this CBA as a baseline comparison for the proposed technologies.
5.1 Present Worth Analysis
A 20 -year present worth analysis was conducted for each alternative in order to compare technology costs holistically. This was completed by assessing the total cost of the technology over a 20 -year life cycle, which include initial capital costs, maintenance costs, and operating cost.
The no action alternative, briefly mentioned in Section 4.8, was added to the present worth analysis in order to compare new technologies to a baseline in which the City continues its current maintenance schedule and practices. The no action alternative was developed based on labor hours and water costs described in Section 4.8. A technology is considered to break even when its life -cycle cost falls below the baseline no action alternative cost.
5.1.1 Capital Cost
An Association for the Advancement of Cost Engineering Level 5 Capital cost was developed for each alternative. Details of the construction costs are included in Appendix E. The construction costs included markups as a percentage of direct costs and is presented in Table 5-1.

5.1.2 Operation and Maintenance
The O&M cost includes water usage cost, energy cost, spare parts, labor hours, vendor support, and equipment or motor overhauls during a 20 -year cycle. Section 4.8 lists maintenance items and their frequency identified during equipment review, and reference interviews.
Energy costs were based on assumed energy cost rates discussed in Section 5.1.3 and assumed operating hours in a day for each alternative. Assumed operating hours were provided as a range from each manufacturer and conservative usage was assumed for costs.
5.1.3 Cost Methodology
The net present value of the 20 -year life -cycle cost for the FOG mitigation alternatives considered both capital and O&M costs in 2021 dollars. O&M costs included the maintenance costs and frequency identified in Table 4-3 and Table 4-4.
The energy cost was incorporated into the life -cycle costs at power rates of $0.285 per kilowatt-hour and $0.353 per kilowatt-hour for BCPS and RBPS, respectively. The energy cost rates were provided by the City.

A comparison plot for the net present value verses operation years is shown on Figure 5-1 for BCPS for all alternatives. The no action alternative curve is shown as red dashed line on Figure 5-1. This alternative considers the City implementing no new technology to mitigate FOG build up over a 20 -year span. Alternatives crossing that curve represents a break-even point with the no action alternative.
Anue and Vapex do not break even within 20 -years of the technology being installed and implemented.
The MicroBlock alternative has the lowest construction cost, but HDR was not able to verify the products performance and check references. Additionally, MicroBlock requires operator attention to monitor performance and impacts downstream processes. This option is not recommended.
PHi has the next lowest 20 -year present worth cost with the lowest energy cost amongst all the alternatives evaluated. However, it has a slightly longer break-even time because of its higher initial capital investment compared to Flygt.
Flygt breaks -even first after MicroBlock in year 7. However, PHi eventually has a lower cost than Flygt because of the lower operating cost associated with PHi. As discussed in Section 4.8, Flygt's 20 -year cost includes a motor overhaul every 5 -years and is still able to have a competitive 20 -year cost.
Anue has a similar construction cost as PHi but a significantly higher annual energy cost because of the large motors required for their equipment. Anue and Vapex require more than 20 -years to break even with the baseline comparison of the no action alternative, as shown in Table 5-2 and Figure 5-1. 09/23/2025

This alternative considers the City implementing no new technology to mitigate FOG build up over a 20 -year span. Alternatives crossing that curve represent a break-even point with the no action alternative.
Vapex does not break even within 20 -years of the technology being installed and implemented.
The MicroBlock alternative has the lowest construction cost, but it is a highly uncertain option as HDR was not able to verify its performance and ability to limit issues. Additionally, MicroBlock requires constant labor hours to monitor the performance and block for any issues to downstream processes.
Flygt and Vaughan have the next lowest 20 -year life -cycle cost. Vapex requires more than 20 -years to break even with the baseline comparison of the no action alternative, as shown in Table 5-3 and Figure 5-2. Flygt breaks -even first after MicroBlock in year 4.5. Additionally, Flygt also has the lowest present worth cost. Flygt's 20 -year cost includes a motor overhaul every 5 -years and is still able to have a competitive 20 -year cost. Vapex's energy costs for RBPS are higher than BCPS because of the higher energy unit cost at the smaller lift station. Return on investments occur at an earlier timeline than BCPS because of the smaller footprint for RBPS. PHi has a longer break-even timeline than its BCPS installation because of its relatively high initial investment for this smaller pump station. 09/23/2025

20 5.1.4 Cost Benefit Analysis Results
The FOG mitigation technology alternatives were scored based on the evaluation criteria and weighed to arrive at the overall score for each technology presented in Table 5-4 and Table 5-5. The no action alternative was considered in this cost -benefit analysis as a baseline comparison for the proposed technologies. The data was computed in a spreadsheet and the technologies are ranked in a descending order in Section 6. Scoring was performed for each lift station and similar scores were obtained. The Reference Track Record scores were based on the feedback received from references.
Flygt, PHi, and Vaughan received positive feedback from its current clients. Constructability scoring was based on the how much additional construction costs were needed to install the alternative. All alternatives require some level of modification to the existing lift stations except MicroBlock, which has the highest score. Anue and PHi have the highest scores for ease of operation because of how simple it is to operate their systems to mitigate FOG relative to the other alternatives. MicroBlock virtually requires the same amount of daily/weekly maintenance already required in a no action scenario. Only Vapex requires a constant feed of potable water for its system, although it is not a significant amount.
PHi may have the only impact on odor control because of the additional air added to the wet wells.
The City should consider the potential impacts on downstream processes that may be caused by the MicroBlock technology. As previously discussed, no references were provided to be able to confirm MicroBlock's performance. Capital and O&M costs are a quantifiable comparison based on the 20 -year life -cycle analyses conducted for all the alternatives. Flygt, MicroBlock PHi, and Vaughan have the lowest capital and O&M costs. Vapex and PHi may provide some additional supplementary benefits, such as odor control for Vapex and rag mitigation for PHi. PHi can suspend rags in the wet well, which would allow for clumps of rag to be minimized and allow the lift station to pump out a lower rate of rags during operation.

For the types of FOG mitigation equipment considered in the lift stations, the Flygt, PHi, and Vaughan systems had the lowest life -cycle cost and highest CBA scores compared to the other three alternatives. MicroBlock is an unknown technology and had the highest O&M costs. The Anue and Vapex systems had the highest capital cost and the highest energy costs. Flygt, PHi, and Vaughan all have a break-even point of less than 10 years, except for PHi at the RBPS. However, consideration shall still be taken for PHi since it is suitable for BCPS and would minimize additional staff training by having the same equipment throughout. Table 6-1 and Table 6-2 present the summary costs for capital, construction, annual O&M, annual energy, years until breaking even with the baseline, and CBA scoring results.
Furthermore, EWA does not recommend Vapex technology due to the potential undesirable downstream impacts at EWPCF, degradation to instrumentation, undesirable impact to biological odor scrubber, and creation of hazardous wet well space that would require extensive ventilation prior to confined space entry.
Based on our analysis and input from Vista and EWA, the top three recommended options for FOG mitigation at BCPS are:
• PHi (Models PHi 350-2/3, BFP, and Kaeser SK Compressor) • Flygt (Model SR -4640 Submersible Mixer)
• Vaughan (Models S4TC-103 and S6UC-113)
Based on our analysis, the top three recommended options for FOG mitigation at RBPS:
• PHi (Model PHi 350-2, BFP, and Kaeser SM Compressor)
• Flygt (Model SR -4640 Submersible Mixer)
• Vaughan (Model S4SC-095)

Raceway Basin and Buena Creek Pump Stations
Buena Creek Pump Station
• FOG cleaning once a week, about 1 hr, 1 person. Sometimes twice per week. • Cleaning is prolonged when pumps clog with rags
• PS is visited daily by operators
• Two grinders in the influent channel.
• Grinders are inspected on quarterly bases and serviced annually. • Lots of rocks and gravel coming through the sewer causing grinders to wear out fast near the bottom of the grinders.
• Inlet pipes have been CCTV recorded.
• Influent sewer is cleaned once per year using Vactor truck to remove cobbles, stones, gravel and silt.
• Grinders: Channel Monster, Model: CDD Hydraulic with gear driven 16- and 20 -inch dual screens.
• Grinder are discontinued and will be replaced by next year. • Grinders operate 24/7.
• Rags passes through grinder.
• Ragging has increased more this past year
• At least once a week a pump is de -ragged manually through the volute inspection port. • Pump clogging with rags also occurs throughout the week aside from FOG mitigation days.
• FOG mats are pushed to the further ends of the wet well as the flow enters the wetwell through center. FOG blankets are pumped out with pumps 1 and 5 • FOG mat is broken by jetting using a hose and flushing using water from the surge tank. • FOG accumulation year-round with no seasonal difference. • FOG mat thickness ranges from few inches to 1 foot if not cleaned periodically and can span the entire area of the wet well.
• Observation: No physical space inside pump room to add any panel or equipment. Plenty of space on -site outside of pump room.
• Bypass of the PS appears to be straightforward, refer to Rehab Study for location.
