1. WS-22-061 Water and Wastewater Grant Opportunities and Submittals Tom began presentation. Joey Soto and Jennifer Nevius are from Soto Resources Jennifer gave the PowerPoint Presentation regarding 2022 Grant Update
Committee Comments/Recommendations
Mayor Pro Tem Scott asked Tom if he was aware of a cistern at a residential home? The building department has discovered a resident with a cistern instead of a septic system.
There may be more in the same neighborhood. May need to ask for separate funding for that. Mayor Pro Tem Scott said, cisterns should be a separate category to request funding because it’s a much more detail clean up than just removing a septic system.
4 Mayor Robertson wants to know if anyone had conversations with the county or coordination with them in terms of what grants are they going to pursue.
Tom said they had a meeting with the Supervisor and his staff, and he followed up with some maps, however he has not had any follow up from them. She said what about West Valley, he said that he spoke to them about the elementary school being on septic. Mayor Robertson directed City Manager to start a dialogue with these other agencies. Maybe ask for an official meeting with the County. Mayor Pro Tem Scott said it was his impression that the Supervisor Baca was open to working with us on going after money for the county pockets in the county area. He added, the area that I think Supervisor felt almost an impossibility without some huge infusion of money was Bloomington.
Marcus said how do we accomplish the onsite connections. He said we have the challenge of how we find the funding. Are there grants to help homeowners pay for the connections. Mayor Robertson mentioned that she attended Mayors Water Council meeting in DC and one of topics was regarding the issue about led pipes; they recognized the costs and burden of changing the lead pipes for the communities. Moreover, septic tanks and areas under the appropriation of recognition. Mayor Robertson said that there was a discussion about having funds available to assist the property owner s with the connection and the indoor plumbing. She said that the problem is that they have not defined or written the guideline s for those bills. Marcus and she will get on the phone with Jamie Jones regarding this.
Mayor Roberson said that all the funds that come out for infrastructure, especially water, need to go directly to the communities. We need to stop having them navigate through a federal direction to the state. The state only delays the process and the ability to put the money and the dollars directly to these issues. She said that we need to focus on the disadvantage communities.
Tom said, during the conversations with the State Water Resources Control on the S RF funding for severely disadvantage communities, they said, if we could create a standalone project that would incorporate all the SDACs and DACs, that would be the most beneficial.
Moreover, if we can consolidate into a single project grant application, we can potentially get a loan forgiven and it would be at no cost. He added, one of the questions we asked them specifically, was the cost on site ? The comment back was , if we as the agency either did the work or provide the funding to a contractor ; they could incorporate that onsite work in the SR fund grant application.
Could get the onsite work included. Peter said they have access to SR F funding, the purple and light purple areas of the map, from power point, could be accommodated for a full forgiveness of the loan. For the WIFIA loan they have funding for the green area on the map, from power point, but it wouldn’t be forgiven. He added, it’s a low-cost loan, and according to his analysis on what could be for a typical homeowner to support something like this over a 30 - or 40-year repayment period. He said it would be between $15 and $25 a month for 30 years added to their water bill if they would not get the forgiveness.
These charges will be added to parties who did not qualify for a low-income status. 5 Mayor Robertson said, we assume that most of homeowners have le ad piping, but it is hard for us to know if there is still lead piping in the home because they have to be tested from the tap water. She asked, how do we address that? She added, led piping is the number one national prior ity. Mayor Robertson said, the houses on Base line, between Acacia Ave. and Eucalyptus Ave on the north side, they probably have led piping.
Mayor Robertson told Jennifer, regarding the 50% match, we need to have a partner.
Mayor Pro Tem Scott said, Tom’s comments including the house connections, i s a very costly proposition. He said taking the connection from 10k and raise it up to 30k, is a big bill. He believes that we have to find other programs to pay for connections.
Mayor Pro Tem asked, is there any harm to going after both projects or do we have better odds for going after Rialto Lake? Tom said that we should possibly go with the Rialto Lake project. He feels that we can put together a good grant application. Mayor Robertson said o ne of the big things that needs to be addressed for disadvantage communities, is contamination. She said the maps that Tom and his team put together for some of the septic issues are within the county pocket areas.
Tom said, we can do that one specifically because we are further along with that and continue to go after DAC funding for that project. Mayor Robertson said that the map on the power point does not show any areas of disadvantage communities. Tom agrees with the Mayor and explained the areas on the map.
Mayor pointed the elementary school located in the same area perhaps in the city boundaries. She said open the door for the work that has already been done. We already have information; she doesn’t want to leave it on the shelf.
Tom concluded by saying, they will go after the project area for sewer to septic and pursue Lake Rialto. Additionally, they are going to focus on the remaining SDACs and DACs toward the state water resources control part, SRF funds; they will create a project for that area. Mayor Robertson said, if we get one project done with BDP, it will underscore the point a lot of mayors were making last week. She added, it takes an endless amount of bureaucracy time to get something out of the shops so people can get going.
2. WS-22-062 Submittal of Projects for State Funding.
Tom and Marcus presented this.
This is Eloise Reyes’ request for a list of projects.
Committee Comments/Recommendations
Mayor Robertson said possibly the Microgrid. Peter said that they have the CIP projects; they aren’t short on projects. Mayor Pro Tem Scott asked if they had something that’s shovel ready at the plant. 30% design on the Microgrid project. Mayor Robertson agreed.
Megan and Peter will get back with Tom. Peter is developing a presentation to discuss with Marcus and Tom to bring to Subcommittee. Risk of raising rates. We should lock in interest rates. Can we consider some of the upstream?
6 Marcus is forwarding email to Peter and Megan and asked them to put something together.
3. WS-22-063 Amendment No. 1 to Professional Services Agreement with Dopudja & Wells Consulting for Lake Rialto Final Design Services and Concession Agreement Support.
Tom gave presentation. Steve prepared a proposal (shown on screen)
Committee Comments/Recommendations
Mayor Robertson commented that she hasn’t seen architectural conceptual of what the presenter is envisioning, where the restroom will be located. Moreover, there is a layout missing. She added, we agreed that we have to figure out a pathway to Agua Mansa and the relationship with the trail. Regarding restroom facilities, Steve said that he will send the Mayor concepts to review, these are more permanent type facilities for restrooms. In terms of access, Steve replied that there are 2 types of access, one is t he individual resident and the second is the school bus. He explained, there is not too much room on site for parking. He said that they will coordinate with the county on that access road that is adjacent to flood control. Steve explained different alternatives for parking access.
Marcus mentioned that there was an inquiry about a piece of land by the water park.
Tom answered, th ere is a 4-acre property located at the entrance of the wastewater treatment plant. Tom mentioned that the property is on sale for $14m.
Mayor Pro Tem Scott said we should enter into some discussions with them. Mayor Robertson asked if there was an agreement with Energia, she said we need to look at it.
Mayor asked Marcus to see what they are proposing; He will talk with the subcommittee members offline.
Side Note
The Committee said to move forward with Steve’s contract at the next Council meeting.
Tom said he has to do an RFP for the environmental. He said they will need a CEQA process for the Microgrid and Lake Rialto. Mayor Robertson said that she wants to see a scheduled milestone. She asked, what is the time frame for finishing the CEQA? Tom said the CEQA should be completed by the end of May, and construction at the beginning of the end of this year if we have funding.
5. WS-22-065 Approval of the City of Rialto’s share to develop the Rialto Basin Groundwater Council Groundwater Management Plan.
Tom gave presentation on the Rialto Basin Ground Water Council Management Plan City’s share $53,750.00 developing a Ground Water Development Plan
Committee Comments/Recommendations
Committee said to move forward.
Tom gave details about the project from Stetson Engineers. He said, their proposal was a total of $197, 600 , contingency was added to the project; the total project budget was 7 $215,000. The budget will be split in four ways equally between West Valley, City of Rialto Water, City of Colton, and Fontana Water Company. The city share is $53,750. He said that he wanted to do an official approval of expending the $53,750 for accomplishing the development of the ground water management plan.
Mayor Robertson said, our recommendation is to move forward.
June Hayes asked Tom to bring information on the Groundwater Council to the Utility Commission. He will.
Marcus asked Tom if there is a join t agreement. Tom replied, no, it is a Budget Resolution. Mayor asked if there is anything else that we need to share in cost? Tom said, right now this is the only cost share that is identif ied. Moreover, there is no other expenses at this point.

Steve Dopudja gave this presentation with PowerPoint.
Committee Comments/Recommendations
Mayor Robertson wants to see what we can do to help them meet their goal of Fall of 2022. Mayor was wondering if the EPA will be handling where the pipe goes in . Mayor Robertson expressed her concerns about the negative impact to disadvantage communities. Marcus said to make sure that the last action required by Council has to happen by the last meeting in September, earlier would be better. 8 Mayor said we should look at us purchasing a well, similar to what Irvine Ranch has done.

Committee Comments/Recommendations
Tom said, the Well No. 5 is being utilized as a monitoring well; they are not using it as a production well because all the production rights are allocated to Rialto Well No. 3 for the combined remedy project. He will present this information to the Utilities Commission as well. No additional comments.
3. WS-22-070 North Riverside Avenue Paving Project - Utilities Update.
Tom gave the presentation
Committee Comments/Recommendations
Marcus said they started this morning, but that we are working with them to get all permits.
He stated that, he and Tom are aggressively pursuing West Valley Water District, and need for them to be proactive. They will have an internal meeting with their staff. If the meeting goes poorly, Marcus will schedule a meeting with Mayor Robertson, Mayor Pro Tem Scott, and their board members to come to an understanding of what are their requirements.
Additional item.
Mayor shared an article on the Triton magazine.
Mayor Robertson suggested a partnership with our schools.
Mayor Robertson and Marcus have been talking about the possibility to track peaks to anticipate COVID. She said, we need to think about how we can put information and monitor through the sewer system; the level of the possibility of COVID outbreak.
Mayor Robertson added, this is important information that it should be updated.
She wants to know if we have the mobility to go even further and isolate the points where things may be coming, or do we just have one massive sewer line, and all comes into one? Mayor Robertson referred to the Triton’s article and said that San Diego Unified School District became the pilot, where they can be able to isolate and track students on campus and locate COVID outbreaks.
9 Mayor Robertson wants to make sure the Rialto City’s data is showing consistency with what is reporting on our community. She said the sewer water would be the ideal place to begin to indicate the health of our community.
Tom share d a document of the results from the treatment plant on COVID. Mayor suggested that we do something with the schools on their plan. She said there could be some grant opportunities.

Final Construction Work Authorization to Rialto Water Services in the amount of $270,907 for Rialto Biosolids Upgrade Study, Plant 1&2 Demolition Design and GMP Preparation, and Additional Electrical Design for the Microgrid Project.
BACKGROUND
The WWTP currently flares 100% of its biogas and expends additional funds on the purchase of natural gas necessary for the flaring process. At the same time, backup power needs for emergencies or the Public Safety Power Shutoffs program will require additional expenditures to acquire onsite diesel generators necessary to operate the WWTP during an electricity interruption or failure.
On July 14, 2020, City Council/Rialto Utility Authority Board (RUA) authorized Rialto Water Services (RWS) to conduct a Feasibility Analysis (Phase 1) on installing/constructing an energy microgrid at the Wastewater Treatment Plant (WWTP). Based on results of the Feasibility Analysis, RWS proposed to complete Phase 2 of the project, to complete a 60% design and develop a Guaranteed Maximum Price (GMP) to construct a Biogas Prime Mover: 360 kW Reciprocating Engine, 1,575 kW Photovoltaic System and 2,460 kWh Lithium-Ion Battery for storage.
On February 23, 2021, the City/RUA authorized RWS to move forward on Phase 2 of the Micro Grid Project. The Rialto Microgrid project will boost resilience and reliability of the utility, improve coverage, and mitigate the need for wastewater rate increases for Rialto’sratepayers. It will also allow the City to end the practice of flaring the plant’sbiogas and associated natural gas; end the burning of natural gas in the hot water boilers; recapture revenue currently expended on SoCal Edison bills; establish backup power capacity without a parallel capital expenditure; improve resiliency to maintain water effluent from plant; and carry “black-start”capability during unexpected utility outages.
ANALYSIS/DISCUSSION
As Phase 2 progressed to the 30% design level, three projects were identified that would be a significate improvement to the Micro Grid project and the WWTP operations. The three projects are:
1. Rialto Biosolids Upgrade Study
2. Plants 1 & 2 Demolition Engineering & GMP preparation
3. Additional Electrical Design & Investigation for determining electrical as-built condition of the Rialto Wastewater Treatment Plant

Rialto Biosolids Upgrade Study: The purpose of this scope of work is to evaluate the existing thickening, digesters, sludge storage and dewatering system to further define the project scope that would be needed for the full biosolids upgrade. It is intended to identify improvements to the digester system, controls, and optimizing gas storage at the digesters. In addition, the thickening equipment, dewatering equipment, and transfer pumping/piping will be evaluated for upgrade. The ultimate goal of this project will be to define the project scope for the future biosolids upgrade.
Plants 1 & 2 Demolition Engineering & GMP preparation: The scope of work under this proposal includes the development of a GMP package for the demolition of the Plants 1 & 2 Primary and Secondary Clarifiers and Chlorine Contact Basins that are determined to be out of service or abandoned in place. The study & GMP preparation phase will include evaluation of hydraulic and electrical isolation of the area from live services, the modifications to the basins to provide for rainwater/stormwater drainage (punch holes in the bottom), the partial demolition of the basin walls to below grade, and the back fill and compaction of area to establish a new working grade.
Additional Electrical Design & Investigation for determining electrical as-built condition of the Rialto Wastewater Treatment Plant: AECOM is in the process of developing several options for onsite power generation and storage through use of a microgrid for the Rialto Wastewater Treatment Plant. As part of this effort, several electrical studies utilizing ETAP software are required to analyze the effectiveness of different designs and operating scenarios for the microgrid for optimization purposes. After reviewing the existing one-lines and other documents for the facility, AECOM has concluded that the existing drawings have insufficient information to create a complete ETAP model.
Therefore, it was determined that a site visit by AECOM personnel and an Electrician is required to inspect individual panels to prepare a complete as-built design of the entire Wastewater Treatment Plant to progress the design further.
FINANCIAL IMPACT
Funding for this project will be paid for with excess funds generate by the Wastewater Fund until such time Rialto Water Services prepares a financial plan to construction the microgrid project as a Concessionaire Initiated Project, with additional funding provided as defined in the Trust and Concession Agreements. Noting that the City has final discretion over financing new projects, and to provide the City with a clear understanding of financing options, RWS will evaluate and present at least options before GMP:
RWS is confident that the project can be readily financed with these financing options and will provide the City with a complete analysis of these alternatives in conjunction with the development of a GMP for the project.
In any event, funding is dependent on completing satisfactory design and engineering with an acceptable project team and GMP pricing. Under the Progressive Design Build approach, the City has complete access to all project related work products including open book cost estimating for all project elements including the recommended project financing option and competitive analysis of alternatives.
The total amount for the FCWA is $270,907 and detailed in the table below.

Rialto Biosolids Upgrade Study, P1&2 Demo and Microgrid Added Electrical Design 24 Rialto Biosolids Project Definition Scope of Services
As part of the Rialto microgrid project, it is proposed to incorporate combined heat and power (CHP) to generate electricity which can offset plant electrical costs. The biosolids systems at Rialto are aged, and upgrades and optimization are recommended to help improve performance, operability and improve reliability of the systems.
The plant has two primary anaerobic digesters (Digester 1 and Digester 2) and one digested sludge storage tank. The sludge storage tank has serious deterioration, has been inoperable for years and is assumed to remain inactive. Significant repairs are required to bring this tank back in service and it would require new mixing systems and sludge transfer pumping. A fourth tank is currently used for belt filter press filtrate, to balance ammonia loads back to the biological process and it is assumed this tank will remain used for this service and not be retrofitted for sludge storage or digestion.
Both primary digesters are equipped with Dystor membrane gasholder covers but only Digester 2 is currently in service and operational. The membrane gasholder cover on Digester 2 is operational but believed to be near the end of its useful service life. The cover generally works well but there are issues with unreliable pressure readings during high wind events (particularly during the Santa Ana Winds).
The membrane gasholder cover on Digester 1 is not believed to be functional anymore and there are concerns from the operations and maintenance staff to bring this digester back in service.
The primary digesters are fed primary sludge thickened in the primary clarifiers and thickened waste activated sludge (TWAS) from the gravity belt thickeners. The digesters are currently fed only during day shift hours (typically between 6 AM to 1 PM) when plant staff is onsite, but it is desired to modify operation to allow for more continuous thickening and sludge feed. The controls of the current system are mostly manual, and they are not tied to the rest of the plants controls or SCADA system. The flow meter on the TWAS line to the digester is not currently functioning and the plant lacks the redundancy needed to allow the system to be taken down long enough to replace it. Digested sludge from the secondary digester is dewatered using belt filter presses and dewatered sludge is conveyed directly to truck loading.
All of the digester gas is currently flared and the controls are set up so that when the differential pressure on the membrane gasholder cover is above a certain set point, gas is fed to the flare but when the differential pressure drops, it shuts down and this creates a cycling of gas flaring. During overnight hours when the digester is not fed, gas production drops off.
The purpose of this scope of work is to evaluate the existing thickening, digesters, sludge storage and dewatering system to further define the project scope that would be needed for the full biosolids upgrade. It is intended to identify improvements to the digester system, controls, and optimizing gas storage at the digesters. In addition, the thickening equipment, dewatering equipment and transfer pumping/piping will be evaluated for upgrade. The ultimate goal of this project will be to define the project scope for the future biosolids upgrade. It is anticipated the upgrade will be delivered as a progressive design build project although different delivery models could be considered.
The scope of work includes the following tasks:
Task 1: Existing Data and Documentation Review
1. Request and review the following items for the existing facility:
25 a. Plant data – Some data has already been provided but gaps or questions in the data will be presented and additional data will be reviewed if made available. b. Future flow and load projections – Need to determine basis of sizing for new equipment.
Will agree to use permitted capacity, a safety factor or population increase with agreement from project partners. This is to ensure sufficient capacity is available with replacement units. A detailed population projection or flow analysis will not be conducted as part of this scope of work.
c. Existing plant drawings and as-builts – Some drawings have been provided but gaps or question will be presented, and additional drawings will be reviewed if made available. d. Applicable reports or studies regarding the biosolids processes – As part of the S1 project some preliminary evaluations were conducted to replace the existing thickening and dewatering system but no digester or sludge storage tank improvements were considered.
2. Review and confirmation for design criteria for thickening, digestion, sludge storage and dewatering.
a. Requirements for sizing basis, operation schedule and redundancy for thickening and dewatering will be confirmed
b. Identify any minimum performance criteria.
Task 2: Develop limited planning criteria
1. Using information from Task 1, develop a mass and energy balance for the biosolids processing facility that includes sludge loads, expected gas production, and digester heating requirements.
This will be done at current existing loading conditions as well as the design conditions agreed to as part of Task 1, 1a.
2. A short letter memo will be submitted summarizing the limited planning criteria
Task 3: Field investigation, condition assessment, and review of existing plant operation
1. Field Investigation and condition assessment. A minimum of two engineers will visit the site to review equipment, building and tank condition. The engineers will also review operation, and maintenance with the plant staff. Current issues, pinch points and other factors that cause unreliable operation will also be considered.
2. Conduct a detailed review of the current digester feed system and identify options to improve and/or automate the digester feed and WAS thickening operations to allow more continuous and steadier digester feed. Determine requirements to incorporate the system into the plant’s SCADA system. For the analysis it will be assumed that the existing WAS GBT thickening system will be replaced with a new WAS thickening system (Task 4) and that a new dewatering system will be installed (Task 5).
3. Review Digester 1 and 2 and identify improvements needed to bring Digester 1 back in service.
Identify potential improvements to Digester 2 that would improve reliability. This includes digester mixing system, heating system, and controls. It is understood that Veolia has completed an evaluation for this and will share findings with the AECOM team.
26 4. Review Sludge Storage Tank condition and identify improvements and new equipment needed to bring the tank back in service. A condition assessment may be needed to determine if the existing tank is usable and suitable for retrofit.
5. Review capacity and operation of the existing Dystor membrane covers, and requirements for replacement with new membrane covers. This work overlaps with the parallel work being conducted as part of the Microgrid project.
6. Identify if needed improvements will trigger further evaluations to meet code requirements, including California seismic upgrades with respect to electrical, structural and geotechnical.
7. Screen options and compile recommended improvements and develop Class 5 cost estimates for options. Veolia will work with AECOM to narrow down to no more than three options.
Task 4: WAS Thickening Equipment Replacement
1. Develop options for replacement of existing WAS gravity belt thickening equipment.
Technologies will be presented and evaluated collaboratively with the project team in a workshop setting (Task 6 – Interim Workshop)
2. A Class 5 budget estimate will be developed for a maximum of three thickening technologies.
3. In conjunction with Task 3, the appurtenance equipment such as WAS feed pumps, thickened sludge pumps and polymer systems will also be evaluated but it is assumed these will need to be replaced.
Task 5: Dewatering Equipment replacement
1. Develop options for replacement of existing belt filter press dewatering equipment.
Technologies will be presented and evaluated collaboratively with the project team in a workshop setting (Task 6 – Interim Workshop)
2. A Class 5 budget estimate will be developed.
3. In conjunction with Task 3, the appurtenance equipment such as dewatering feed pumps and polymer systems will also be evaluated but it is assumed these will need to be replaced.
Task 6: Workshops and Technical Memorandum
1. Kick-off Workshop - A kick-off workshop will be held to confirm scope, information requests, and project objectives.
2. Interim Workshop – An interim workshop will be held to discuss options considered in Tasks 2, 3, 4, and 5. The workshop will be used to finalize the options that will be presented in the draft technical memo.
3. Draft Project Definition Technical Memorandum – A draft technical memorandum will be prepared to summarize the findings of Tasks 1 to 5.
27 4. Final Workshop – A workshop will be held after submittal of the draft technical memorandum to review the findings.
5. Final Project Definition Technical Memorandum – The final technical memorandum will be submitted within 2 weeks after the final workshop and comments are received.
Task 7: Develop Scope and Schedule for Detailed Design
1. Scope of Work – Pending agreement with all parties, a scope of work will be provided to implement the recommendations of the Final Project Technical Memorandum. It is anticipated the scope will be implemented as a progressive design build although other delivery models such as a traditional design bid build could be considered. The scope for design will include the following milestones:
a. Basis of Design Report
b. 30% Design
c. 60% Design
2. Cost Estimates – As part of the scope of design, cost estimates will be provided at different points in the design.
a. Class 5 estimate will be provided with the Basis of Design Report b. Class 4 estimate will be provided with the 30% design c. Class 3 open book cost estimates will be provided upon completion of 60% design
3. Schedule – A preliminary project implementation schedule will be provided as part of the scope.
Assumptions:
- CHP sizing requirements are being developed under a separate scope of work - Any supplemental gas storage requirements needed are being evaluated under a separate scope of work.
- Dewatered cake will continue to be loaded in trucks using the same conveyance system.
Alternative cake conveyance/storage options will not be evaluated as part of this scope. - Draft and Final Technical Memorandums will be electronic deliverables. - Following the site visits, meetings/workshops will be held virtually over Microsoft Teams. - Comments on draft technical memorandum will be provided by Veolia within 2 weeks.

Demolition Estimate
Proposal to prepare GMP estimate for Plants 1 & 2 Clarifier and Contact Basin Demolition
Dear CV
AECOM Technical Services (AECOM) is pleased to submit this letter proposal to Veolia Water team to support the planned solar installation at the Rialto Water Treatment Plant to demolish as necessary Clarifiers (Qty: 4) and Chlorine Contact Basins (Qty 2) that are decommissioned and abandoned in place . The final deliverable under this proposal will be a demolition work package and guaranteed maximum price proposal to execute the work under this package. For these services, AECOM requests $ 43,800 to be authorized under a separate agreement than our current Micro grid purchase order on a Time and Materials (NTE) basis, to be executed under our current DB contract with T&C’s as modified herein . AECOM assumes 4 – 6 weeks for development of the GMP from Notice to Proceed (NP).
1. Background
The Rialto Waste Water Treatment Plant (WWTP) is currently considering the development and installation of a microgrid to manage proposed onsite power production capabilities to better utilize biogas generated in their digestors, reduce flaring, and provide a more resilient electrical grid. To this end, the current approach includes nearly 1,200 kWAC contributed from three solar arrays. Additional constraints recently encumbered by the project resulted in a larger installation necessary in the cen tral plant. The area that is selected for the solar installation is occupied by Four Primary and Secondary Clarifiers and two Chlorine Contact Basins (and ancillaries). This equipment has been marked for demolition by the Facility to make way for the solar installation, but separately funded than the Microgrid project as this abandoned equipment represents an existing condition. AECOM has been directed to assemble an estimate to develop a guaranteed maximum (GMP) price for the demolition. AECOM has assembled this proposal to this end relying on continuing our work partnership with W. M. Lyles Co. (Lyles) for our approach.
AECOM and Lyles have recently developed an order of magnitude estimate for this demolition. This approach will incorporate the steps considered by that estimate,
2. Proposed Scope of Work
The scope of work under this proposal includes the development of a GMP package for the demolition of the Plants 1 & 2 Primary and Secondary Clarifiers and Chlorine Contact Basins that are determined to be out of service / abandoned in place. Our plan of attack includes the hydraulic and electrical isolation of the area from live services, the modifications to the basins to provide for rainwater / stormwater drainage (punch holes in the bottom), the partial demolition of the basin walls to below grade, and the back fill and compaction of area to establish a new working grade. Equipment, including structural, piping, and electrical fixtures will be demolished or removed as necessary to clear the area for a planne d installation of solar arrays.

2/3
Our approach assumes that the current demo plan is acceptable and that no unique actions are required by the Facility or the AECOM team to resolve such as resolving soils or equipment contamination, or other remediation issues like asbestos or lead.
3. Proposed Scope of Services
AECOM will initially mobilize to conduct a thorough inhouse drawing review using documents provided to us already to fully appreciate and understand the scale of the demolition and the necessary isolati on points to ensure worker safety and stable operations to the facility. Drawings will be red lined and a preliminary package assembled with scope of work outlined. This package will also include necessary work to stabilize areas that could be compromised during demolition activities.
AECOM will conduct a field walk with Lyles to review and confirm elements of the draft isolation and demo plans, and to confirm our developed narrative and assumption bases.
Using this generated data and execution plan, we will assemble a project GMP price for WWTP to consider and if accepted, execute.
3.1 Deliverables under this proposal include:
AECOM anticipates creation or revision of the following documents:
1. Prepare a draft project demolition plan to include redlines of existing drawings,
2. Prepare a field visit plan identifying what specific information we will require to generate our estimate
3. Prepare a project execution plan to outline the basic timing, cost, risk and technical needs for the GMP proposal
4. Prepare a GMP proposal estimate to implement the work as developed.
3.2 Assumptions
1. The current plant is shown as decommissioned with some areas repurposed for other uses. The Rialto Microgrid Project requires clearing of this area. The concept under this proposal includes a partial demolition of the clarifiers and contact basins, to below grade, punching drainage holes in the structures, and filling / compacting the basins to plant grade. This proposal does not anticipate further work outside of demolition to secure or optimize remaining assets.
2. The local authorities having jurisdiction will approve the demo plan as described. AECOM has not included time for meeting with 3rd parties to solicit approvals or letters of no objection.
3. Our current proposal does not include 3rd party activity for soils testing, nor lead or asbestos surveys.
If during our field walk, these items are noticed in appreciable quantities, AECOM will request that the WWTP provide a quantifying survey of these items, or if not available, will build this cost into the GMP strategy.
4. Proposal includes one site visit for project kickoff and field survey.
3.3 Schedule
AECOM and Lyles will provide services as required to achieve the intent of the following schedule:

2 Background
AECOM is in the process of developing several options for onsite power generation and storage through use of a microgrid for the Rialto Wastewater Treatment Plant (RWTP). As part of this effort, several electrical studies utilizing ETAP software are required to analyze the effectiveness of different designs and operating scenarios for the microgrid. After reviewing the existing one-lines and other documents for the facility, AECOM has concluded that the existing drawings have insufficient information to create a complete ETAP model. Therefore, it was determined that a site visit by AECOM personnel is required to progress further.
Scope of Work
Electrical Site Visit - AECOM will conduct a complete walkthrough of plants 1 through 5 documenting and taking pictures of electrical equipment to confirm information regarding the Switchgears, MCCs, Cables, and Protective devices located throughout the RWTP. Specific info AECOM is looking to verify includes:
• Conductor lengths, sizes, and insulation types
• Relay/circuit breaker sizes, manufacturer, model #, and protective devices settings • Ratings of electrical Switchgears, Motor Control Centers (MCCs), Electrical Panelboards, and various other electrical distribution equipment.
• Identify and locate circuits and equipment feeds that have not been verified in existing drawings. • Update ETAP software model reflecting the current configuration at the facility • Grounding arrangements for the two main substation transformers, main switchboards, alternate transfer switches, and standby generators.
AECOM will provide Redline markups of one-line diagrams, cable schedules, panel schedules, and any other electrical documents that were found to be incorrect. These redlines will be included in the full Arc Flash Study to be performed in the 60% design phase.
Excluded Scope
The following items are excluded from the scope of this document:
Electrician Services- AECOM will not be responsible for services that require a licensed electrician to perform such as but not limited to: opening panels, handling cables, opening circuit breakers, etc.
Schedule
The site visit is expected to last 5 working days, outlined as follows:
• Day 1- Participate in any site-specific safety training. Begin verification of electrical substation and Plant 1-4 equipment starting with SWGRs 1A & 1B and continuing onto the various MCCs, Panelboards, etc. fed from the switchgears.
• Day 2- Continue verifying equipment in Plants 1-4
• Day 3 – Finish verification of Plants 1-4 equipment. Start work on Plant 5 equipment starting with SWBD-C and continuing onto the various MCCs, Panelboards, etc. Fed from the switchboard. • Day 4 – Continue verifying equipment in Plant 5
• Day 5 – Complete verification of Plant 5 equipment. Final verification of any equipment that may have been missed on days 1-4.

TO: Water Subcommittee Members
FROM: Thomas J. Crowley, P.E., Utilities Manager
Update on the Payment Trends during the City’s Local Emergency due to the COVID-19 Pandemic.
BACKGROUND
Since the Declaration of Emergency due to COVID-19 was instituted in March 2020 and at the direction of Council, Rialto Water Services has not turned off any water or sewer serves due to the lack of payment. In addition, has not assessed any late fees or interest on any of the accounts to date.
ANALYSIS/DISCUSSION
Below are some trends related to the number of residential and commercial water and sewer accounts that are 30, 60, 90, and 120 days past due. The two charts below show the number of accounts that are past due, and the other chart shows the total amount past due. These charts do not include the sewer only accounts for residential and commercial since some customers tend to wait to be placed on the tax roll.

Water Shut off Survey
In conducting a surveying of the surrounding agencies with regards to water shut offs, we found varying opinions, below are their responses.
Fontana Water Company: Following the state lifting its COVID-19 no turn-off moratorium, Fontana Water Company reinstituted its SB 998 turn off policies (79 days of non-payment before discontinuance) in late January. This will result in turn-offs for delinquent payments starting in mid- March.
City of Colton: Most of Colton’s customers pay a water, sewer and electric, which electric is the driving factor the gets them to pay. Not an issue for them.
City of San Bernardino Water Department: San Bernadino has not resumed shut offs. They planned on starting March 1 to make sure the water bill arrearages funds from the state were applied to delinquent balances, which they have done, but are now holding off until the sewer arrearages funds are applied. Might be a couple of months before they begin water turn offs.
West Valley Water District: WVWD has not resumed shut offs. No firm plans to do so.
