P-384 TCP Treatment Facility Project (Project)

The Project consists of construction and operation of a granular activated carbon filtration facility (“Treatment Facility”) to remove 1,2,3 TCP (“TCP”) from up to 80 cubic feet per second per day of groundwater conveyed though the District’s existing P-384 Distribution System to the California Aqueduct (“Aqueduct”) to meet Aqueduct TCP water quality standards or requirements. The Treatment Facility will be located within a fenced approximately 8.52-acre site, located immediately adjacent to the existing P-384 Distribution System Pump Station and Pond-Poso Canal, to be acquired by the District for the Project and principally housed within a treatment structure covered by a building about 112 feet wide and 222 feet long. The facility also includes a storage tank and holding pond for carbon filter backwash, and related appurtenances for operating the facility including managing inflow and outflow of water, located on the same site. The Treatment Facility will be directly connected to and an extension of the adjacent P-384 Distribution System (including its pump station and appurtenant structures). The P-384 Distribution System is used to convey water including return of the District’s banking partners’ surface supplies previously stored in the aquifer underlying the District (groundwater), via the Aqueduct. The Project’s removal of TCP will not result in any expansion in existing or former use of the P-384 Distribution System or otherwise.
