WRRF Phase II Improvement Projects

About the WRRF Phase II Improvements Project

The Water Resource Recovery Facility (WRRF), formerly Water Pollution Control Facility (WPCF), Phase II Facilities Plan, which was completed in 2020, was prepared to guide the WRRF infrastructure needs for the next twenty years. The Phase II Facilities Plan updates the previous master plan to incorporate new facilities needed to address future regulatory requirements restricting discharge of nutrients to the Bay. The WRRF Phase II Improvements Project will include two projects as highlighted below.

07760 – WRRF Phase II Improvement Project: The WRRF Phase II Improvement Project will reduce nutrient loading to comply with the Regional Water Quality Control Board’s Third Watershed Permit . In addition, the project will rehabilitate aging infrastructure and increase hydraulic capacity of the WRRF. Major project components include a new biological nutrient removal facility, a new grit removal facility, a new primary effluent equalization facility, rehabilitation of the existing final clarifiers, and demolition of the existing west trickling filter. In July 2022, a professional services agreement was awarded to Brown and Caldwell to begin preliminary design of the Phase II Improvements. The total project is estimated to cost over $200 million and is expected to be completed in 2030. As part of the design effort, staff have applied for a USEPA Water Infrastructure Finance and Innovation Act (WIFIA) loan to help fund the project. The City is also securing bond financing.

 

07786 - WRRF New Administration Building and Laboratory Project: The 2020 WRRF Facilities Plan included planning for a new administration building and laboratory space to replace aged infrastructure that can no longer house the required number of staff at the WRRF or efficiently serve the laboratory needs at the plant. A new administration building is included in the WRRF Phase II Project as an early bid package and is estimated to cost approximately $40 million. Construction is anticipated to begin in May 2025.
