4. DESCRIPTION OF THE WORK. The Work consists of, in general, providing progressive design-build services for developing the Mocho PFAS Treatment Plant and rehabilitating aging infrastructure of the Mocho wells to enable PFAS removal from this wellfield. The project will restore the production capacity and water supply reliability of the Mocho wellfield in Pleasanton to support continuous water delivery to the region. It will also remove operational constraints on the Mocho Groundwater Demineralization Plant (MGDP) which helps remove salt from the groundwater basin. All work is located at the Mocho wellfield at the intersection of Santa Rita Rd. and Stoneridge Dr. in the City of Pleasanton.

The anticipated cost of this project is $35-$51 million. In addition to existing and planned rate-based capital funds and past grant proceeds, the project could be funded by the issuance of bond instruments, additional grants or loans. Zone 7 was awarded a grant for $1.2 million from the California Department of Water Resources for the Wells and MGDP Electrical Modernization Project, which includes replacing the Mocho 3 and 4 switchgears, and is actively working to secure additional state as well as federal funding.
