WPCF Nutrient Management & Phase II Improvements
The City is upgrading its wastewater treatment processes to limit the discharge of nutrients to the Bay in compliance with upcoming regulatory requirements. The improvements will also accommodate future increased flows as Hayward’s population increases.
The Bay, like all bodies of water, is comprised of nutrients that must remain balanced to maintain the health of the ecosystem. In recent years, however, certain nutrients like nitrogen have reached excessive levels, prompting concern about environmentally-harmful events like algae blooms. The City has committed to nutrient reduction in advance of upcoming regulatory requirements as an early adopter and has begun design of improvements that will enhance the treatment process and further protect the Bay.
Estimated Project Timeline
Nutrient Management Strategy Development: Early 2018 to Early 2022
Preliminary Design Phase: Summer 2022 to Summer 2023
Final Design Phase: Early 2023 to Late 2024
Construction Phase: Summer 2024 to Late 2028
Construction of the improvements is currently estimated to cost $130 to $180 million. More details about the budget are included in the Adopted FY 2023-2032 Capital Improvement Program (CIP).
