Santa Paula 再生水厂

Santa Paula, California

The existing City of Santa Paula Wastewater Treatment Plant was constructed in 1939 and most of the facilities have reached the end of their useful service life and are non-compliant with current regulatory requirements.  The existing facility has a capacity of 2.55 MGD (9,700 m3/day) which is insufficient to meet future growth demands of the City and therefore additional capacity is required.  The City is planning to replace the existing facility with a new Water Recycling Facility (WRF) and percolation system to be constructed on approximately 53 acres (21.5 hectares) immediately south of the existing facility.  PACE was contracted as part of the design-build-operate-finance (DBOF) team to provide engineering for the new WRF, which will be designed as a Membrane Bio Reactor (MBR) with an initial capacity of 3.4 MGD (12,900 m3/day) and readily expandable to 4.2 MGD (15,900 m3/day) to meet wastewater flow projections for the year 2025.  Also included in the new WRF design are three percolation basins with a combined surface area of about 15 acres (6 hectares) located to the west of the WRF site.  The Santa Paula WWTP will be the largest Koch MBR facility in the United States upon completion.  The WWTP is also the first DBOF municipal WWTP in California.
