Sunol Valley Water Treatment Plant Expansion and Treated Water Reservoir (Sunol Valley Water Treatment Plant Ozonation Facility and Other Site Improvements Proj

The SFPUC proposes to modify the approved Sunol Valley Water Treatment Plant Expansion and Treated Water Reservoir project to construct a new ozonation facility and a new polymer feed facility at the plant, and to conduct repairs and improvements to existing treatment facilities at the plant. SFPUC also proposes electrical equipment upgrades at facilities that deliver power to the treatment plant to ensure that operation of the ozonation facility does not cause overloads on the Calaveras Substation main transformer, approximately 2 miles north of the plant. The proposed new ozonation facility, new polymer feed facility, upgrades to existing plant treatment facilities, and electrical upgrades constitute the modified project. The purpose of the modified project is to ensure reliable operation of the treatment plant and to meet customer expectations regarding water quality.
