That the City Council adopts the attached resolution (Attachment II) approving the plans and specifications and use of certain sole source products for the WRRF’s Effluent Channel Return Pump Station Project (Project), Project No. 07806, and calling for construction bids to be received on July 21, 2026.

SUMMARY
The WRRF treats an average flow of approximately 11 million gallons per day (MGD) and meets current regulatory requirements for discharge of treated effluent to the deep waters of San Francisco Bay.
During storm events, influent flows can exceed the WRRF’s discharge capacity, requiring temporary storage of treated wastewater in the facility’s storage ponds. Timely return of stored water from the ponds to the chlorination channel is essential to restore available pond capacity and maintain readiness for continuing or subsequent storms. Increased pumping capacity is therefore necessary to improve wet-weather flow management, reduce operational risk, and strengthen system resiliency during peak events.
Hydroscience Engineers has completed the design of a new return pumping station at Pond 4 that will increase pumping capacity from the existing 1 MGD system to 3 MGD. Design plans, specifications, and bidding documents have been prepared. Staff is requesting City Council approval to advertise the calling for bids to be received on July 21, 2026.
