Document Description
The proposed project consists of development of a State Street Water Treatment Facility (State Street WTF), which will be a new centralized treatment project that will treat water from Wells 12 and 14 for nitrate, perchlorate, and 1,2,3-TCP. The project also includes installation of offsite water transmission and brine pipelines, improve-ments to the existing wells, and site improvements. The water treatment facility will have a capacity to treat up to 4,000 gallons per minute (gpm) and the anticipated extraction rate from each well is 2,000 gpm. As stated above, the proposed project would provide treatment for nitrate, perchlorate, and 1,2,3 TCP at Wells 12 and 14. Treatment is anticipated to include pretreatment through sand separators followed by cartridge filters (solids removal), 1,2,3-TCP Removal through Granular Activated Carbon (GAC), perchlorate and nitrate removal through a proprietary ion exchange (IX) treatment system, then disinfection and storage in Reservoir 5 before distribution. The IX treatment system generates wastewater known as brine, that will be disposed of through a new connection to north Non-Reclaimable Wastewater System (NRWS) brine disposal pipeline that is managed locally by the Inland Empire Utilities Agency (IEUA). The GAC system generates a periodic backwash water when the media is replaced that will be disposed of through a local sewer connection.
