Description
Zone 7 is 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. To help address PFAS in the Mocho wellfield, a new centralized treatment facility (Mocho PFAS Treatment Plant) located at the Mocho Well 3 site has been identified as the preferred approach. Options for design and construction of this facility and the removal of PFAS from the wellfield water vary, and may include: PFAS and salt removal through MGDP reverse osmosis (RO) trains, and the Mocho PFAS Treatment Plant removing PFAS from the water bypassing the RO trains, PFAS removal from all of the wellfield water through the Mocho PFAS Treatment Plant, with MGDP continuing to operate for salt removal from the groundwater basin,
Bonds required. Prevailing wages.
