City of Garden Grove Wells 22, 26, and 27 PFAS Water Treatment Plants Project

Construction of three separate wellhead water treatment plants for the City of Garden Grove to remove Per- and Polyfluoroalkyl substances (PFAS) contaminants at the Well 22, 26, and 27 before distributing the treated drinking water to the City’s customers.

Construction includes procurement and installation of ion exchange (IX) pressure vessel systems, pre-filter cartridge filtration systems and sand separator systems (Well 26 and 27 only); connection to individual wells and treated water discharge points, installation of valves, piping, meters, electrical, instrumentation, and other ancillary and support facilities; constructing site improvements and fences, excavation, and pavement replacement; providing warranty and guarantees; and completing all associated commissioning, training, and acceptance testing for a fully functional water treatment plant.

For Well 26, work also includes procurement and installation of a new 600 horsepower well pump and motor, variable frequency drive, programmable logic controller, switchboard and other electrical improvements; construction of pump building improvements and procurement and installation of HVAC system; construction of new chemical and electrical building for Well 26 PFAS Water Treatment Plant including HVAC system; procurement and installation of chemical storage tank, metering system, dosing system and mixer; and off-site piping between Well 26, Well 26 PFAS Water Treatment Plant, and distribution system.
