Construction continues in Mission Trails Regional Park to upgrade the San Diego County Water Authority’s untreated water supply system. The estimated completion of the project has been extended from mid-2022 to late 2022 due mostly to necessary design changes. The project will improve the delivery of a safe and reliable water supply to treatment plants serving the central and southern areas of San Diego County.

Trail closures will continue Monday through Friday from 7 a.m. to 7 p.m. and reopen as soon as it is safe. The Water Authority’s work in Mission Trails Work will not affect the delivery of high quality drinking water to homes. Graphic: San Diego County Water Authority
