Las Gallinas Valley Sanitary District Recycled Water Facility

Completed 2012

Cost $6.8 million

Size 1.4 to 5.6 MGD

Type Tertiary Treatment

Working with the District, AQUA assisted in designing and constructing a fast track project to provide recycled water to the North Marin Water District (NMWD). The recycled water facility was added to the back end of the existing facility processes and includes coagulation, pressure filtration using GE membranes, UV disinfection, and effluent pumping to deliver the water. The existing site did not allow much space for the addition of facilities, but working creatively with the District, the necessary facilities were added to the site. This upgrade allows the District to provide Title 22 compliant recycled water to NMWD. The initial phase provides 1.4 MGD of capacity and can be expanded by just adding additional equipment to 5.6 MGD. AQUA also provided onsite construction management for the upgrade project.
