Document Description
The project is the expansion of the existing Castaic Lake Water Agency (CLWA) Rio Vista Water Treatment Plant (RVWTP) treatment capacity from 30 million gallons per day (mgd) to 60 mgd (16,790 acre-feet per year [AFY] to 33,580 AFY [Average Annual Load]) in response to current and new water quality standards, to improve reliability to meet existing customer demands, and planned future demand. The 16,790 AFY of additional treated water provided by the project would be able to serve between approximately 17,309 and 18,054 households, or between approximately 55,389 and 57,773 persons. Additionally, modifications to the existing ozone treatment system at the RVWTP would be completed.
