For Meeting of: October 15, 2024 ITEM TITLE: Resolution authorizing an Agreement with Apollo, Inc. for Project WF2761 Biosolids Dewatering Improvements at the Wastewater Treatment Plant SUBMITTED BY: Scott Schafer, Director of Public Works * Mike Price, Wastewater/Stormwater Manager SUMMARY EXPLANATION: Biosolids generated during the wastewater treatment process at the City of Yakima (City) Wastewater Treatment Plant require dewatering to reduce hauling costs to beneficial use sites. The treatment plant currently utilizes two aging dewatering centrifuges that have reached the end of their service lives. The centrifuge process is energy intensive, requires frequent expensive maintenance by specialist repair firms, and requires the full-time attendance of a wastewater treatment plant operator. The Wastewater Division's facility planning process identified screwpress dewatering technology as a proven replacement for centrifugation. The City ran three successful screwpress pilot studies at the treatment plant between 2019 and 2022 to verify effective biosolids dewatering with the screwpress process. City Project WF2761 replaces the centrifuges with screwpress units that require low power input, reduced maintenance, and only part-time operator attendance. A preliminary power usage analysis showed that replacing the centrifuges could save up to 500,000 kilowatt hours of power usage annually, potentially qualifying the project for a reimbursement of up to $100,000. The project also includes biosolids conveyor improvements that allow efficient and unattended loadout of dewatered biosolids to the transport trailers. The City previously entered into an agreement with RH2 Engineering, Inc. under Resolution R-2023-094 to provide design, bidding, and construction services for the improvements. The City utilized the procedure established by the State of Washington for competitively bidding projects. Four contractors submitted bids, with Apollo, Inc. submitting the lowest bid of$5,996,895.90. The Agreement in an amount not to exceed $5,996,895.90 is attached for City Council review. The project is funded by Wastewater Capital Fund 478.

Contractor Initiated Request for information (RFI) No. 011 Owner: City of Yakima Project: Biosolids Building Dewatering Improvements Project No: 23-0121 Engineer: RH2 Engineering, Inc. Contractor: Apollo Review Priority: © 1 (five working days) ❑ 2 (ten working days) ❑ 3 (fifteen working days) Date of Requested Response (based on review priority): 12/23/2025 Reference Drawing(s): E07, Ell & E12 Specification Sections): Description of Request: 1. 10" PRS Different than shown on M301 and M302. The Contract Drawings show the existing 10" PRS to have existing flanged connections. The existing elbow nearest the wall penetration that we are supposed to connect to does not exist and is welded (see attached photo). There is a flange on the other end where the pipe turns down vertically that we can connect to. Is it acceptable to make the connection to the existing 10" PRS at the vertical drop location in lieu of elbow near the wall penetration since the [elbow] at the wall penetration would have to be cut and welded? 2. There is an existing 4" cast-iron soil pipe and an existing 4" ductile iron pipe inside the centrate tank but not shown on the drawings. These pipes are believed to be floor drawings from the main dewatering room. Both existing pipes have significant corrosion. Does the City want to replace this piping while the tank is drained? See attached photo. 3. There is significant corrosion of the interior concrete walls, ceiling and around the existing hatch due to the corrosive environment of the centrate tank (see attached photo). The depth of concrete corrosion appears to be approximately 1" in depth and now would be the time to complete any necessary repairs while the tank is out of service. If the City elects to have us repair the surface, please provide the desired repair method. We assume the repair would include removal of concrete to sound substrate, repair with cement based or epoxy -based filler/repair product and potentially adding a high-performance coating to the concrete surfaces.

Date: 12/17/2025 Engineer's Response: 1. Yes, it is acceptable to make the connection to the existing 10" PRS flange. Connection to be made with Sch. 80 PVC per Attachment 1. Replace 4" cast-iron soil pipe with 4" sch. 40 PVC (SW). Transition to PVC outside of the centrate wetwell in the basement area. Terminate the PVC drain north of the wetwell baffle approximately 1'-4" above the bottom of the wetwell. All hangers/supports/anchors/hardware to be stainless steel. Reuse existing Zink seal and hangers as possible. Replace 4" ductile iron pipe with 4" sch. 40. PVC (SW). Transition to PVC at cast -in -place DI flanged spool. Replace existing flange anchors inside the wetwell with stainless steel anchors. All hangers/supports/anchor/hardware to be stainless steel. Terminate the PVC C2 pipe north of the wetwell baffle approximately 1'-4" above the bottom of the wetwell. 3. Repair concrete with Moratec Cladliner. Abrasive blasting, surface preparation, and application to be performed per manufacturer's recommendations, Attachment 2. Assumed area to be repaired shall include all concrete surfaces (walls, ceiling, and roof hatch) above top of the existing baffle (approx. 4'-6" below the wetwell ceiling). Apollo to verify the extents of the corroded area with exposed aggregate and confirm with RH2 prior to ordering material. Attachments: 1. Revised Sheets M301 and M302 2.
