RWF Headworks Improvements and New Headworks

File No. PP17-046

The Project involves the potential rehabilitation of Interceptor 1 and the design and construction of a new headworks (Headworks 3) to serve as the duty headworks for the San Jose’-Santa Clara Regional Wastewater Facility (RWF). Once online, the existing Headworks 1 would be taken out of service and the new Headworks 3 would be operated in conjunction with Headworks 2, which would continue to serve as the wet weather peak flow headworks. The project also includes re-routing and modifications to a number of influent pipelines, improvements to the Emergency Basin Overflow Structure (EBOS), and excavation and lining of the existing Emergency Storage Basin. The Project would not change the existing projected capacity of the headworks facilities, which is 400 million gallons per day (mgd) extreme peak hour wet weather flow.
