Construction


CONSTRUCTION BEGINS SUMMER 2022 

The East County Advanced Water Purification Program is starting construction this summer. The Program create a new, local, sustainable and drought-proof drinking water supply using state-of- the-art technology to purify East San Diego County’s recycled water to produce up to 30% of the region’s drinking water. 

 The Program’s treatment facilities will be constructed just to the north of Santee Lakes. The purified water pipeline will travel east through Santee and Lakeside, ending at Lake Jennings. Two additional pipelines will be constructed south of the new facilities past Carlton Oaks Drive to a pump station just south of the Carlton Oaks golf course. Most of the pipeline work will be trenched, placed and covered in roadways. We realize there will be impacts from construction and we appreciate your patience with noise and road travel delays while work is underway.
