Williams Road Station PFAS Treatment Facility Project

FILE NOS: CP24-025 and ER24-166

Conditional Use permit to develop a new water treatment facility within the existing Williams Groundwater Station site. The proposed treatment facility would have a design capacity of 20,000 gallons per minute and would use ion exchange resin to treat water from the existing groundwater wells located on-site. There would be no change in water use or capacity. The proposed facility would consist of steel treatment vessels under a metal canopy, two water tanks, an electrical and feed pump station building, stormwater bioretention basin and associated infrastructure, a process drain pump station, an emergency diesel standby generator, underground piping to connect the wells and treatment system, and perimeter security fencing and driveway modifications.

LOCATION

The 11-acre project site is 3601 and 3605 Williams Road in the City of San José.
