Lost Canyon 2A and Sand Canyon Groundwater Treatment Improvements Project

The project involves construction of a centralized per- and polyfluoroalkyl (PFAS) groundwater treatment facility, improvements to the existing Sand Canyon and Lost Canyon 2A wells, replacement of an approximately 1,700 feet of 14-inch pipeline along Lost Canyon Road, decommissioning of the existing Mitchell 5B and Lost Canyon 2 wells, and various site improvements including electrical, piping, and access upgrades. The project would restore the use of the Lost Canyon 2A and Sand Canyon wells and would reduce SCV Water’s dependency on imported water. Construction would occur between approximately May 2026 and May 2028. The groundwater treatment and disinfection facility would operate 24 hours per day, 365 days per year. Maintenance activities would include daily maintenance staff visits, weekly chemical deliveries, and resin media replacement approximately every 9 to 12 months.
