Delta Diablo Sanitation District Recycled Water Facility

The Delta Diablo Sanitation District Recycled Water Facility, built for Calpine, produces title-22 water to feed two power plants and 20 acres of parks and landscaped areas. It includes complex cast-in-place concrete structures using over 25,000 cubic yards of concrete to support the "purple pipline" that saves over 8600 acre feet of potable water every year.
