ESD Extra: Headworks Construction Project Will Modernize the “First Line of Defense” in Wastewater Treatment Process

Post Date:07/06/2020 8:00 AM


Since 1956, the San José-Santa Clara Regional Wastewater Facility has operated nonstop, 24 hours a day, seven days a week, 365 days per year, cleaning Silicon Valley’s wastewater to the highest national standards. Not even a global pandemic has stopped this streak, and we’re proud to continue to provide this essential service that protects the health of our residents and the wildlife of San Francisco Bay.

Our work to modernize the Facility with exciting new technologies and infrastructure is happening through the Capital Improvement Program (CIP), a $1.4 billion, 10-year construction project. This June, the CIP and RWF hit a milestone with the official start of the new Headworks project.

The Headworks Facility is essentially the first part of the wastewater treatment process, removing the debris and grit that finds its way into our wastewater. The RWF currently has two Headworks, including Headworks 1, which has been in operation for more than 50 years. Once Headworks 3 is completed, the original equipment will be retired. The construction of a new Headworks will improve the facility’s performance and reliability, as well as prepare the facility for any changes in climate conditions (sea level rise, natural disasters) as well as population growth. Thanks to the new Headworks, the facility will be able to treat up to 400 million gallons of wastewater a day.
