WPCF Nutrient Management & Phase II Improvements

Water Pollution Control Facility

 
Pictured above is the Water Resource Recovery Facility (WRRF, formerly WPCF), which treats an average of 11 million gallons of wastewater per day. The WRRF will soon undergo significant improvements to enhance the quality of the wastewater discharged into the San Francisco Bay. 

Project Overview

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 anticipates that upcoming regulations from the Regional Water Quality Control Board will require removal of 50% of nutrients by the year 2034. The City has begun design of improvements to comply with these upcoming regulations that will enhance the treatment process and further protect the Bay. 

The Exhibit below highlights major proposed improvements.
