The recently upgraded Patterson Pass Water Treatment Plant will be opening its doors to the public for in-person tours on June 17! 

In June of 2022, the water treatment facility completed major construction upgrades to ensure we are delivering the highest quality water to the businesses and residents of the Tri-Valley. 

In addition to important facility upgrades, Patterson Pass now offers ozonation as a treatment for your water. We also doubled the plant’s production capacity from 12 million gallons of water per day to 24 million gallons per day!

We are excited to invite the public to tour the upgraded facility to learn about how your water is treated and delivered to your homes and businesses.
