Patterson Pass Water Treatment Plant Improvements

Overaa Green Project

Project Details

This project doubled the amount of treated water the plant can produce from 12 million gallons of water a day to 24 million gallons a day. New ozone treatment capabilities improve the quality of finished water, and a new storage tank boosts capacity of treated water by 5 million gallons. New infrastructure within the plant, which has been serving the Tri-Valley area since 1962, improves overall reliability.
