Pittsburg Water’s local water treatment

Pittsburg Water manages its own local treatment plant where we treat and conduct rigorous testing every four hours to ensure the quality and safety of our water. We treat, test, and deliver almost 3.3 billion gallons of safe water each year, which is enough water for 546 million dishwasher cycles. 

We worry about your water 24/7, so you don’t have to do the same.

Water source

Pittsburg Water purchases raw (untreated) water from Contra Costa Water District that is delivered to our locally managed treatment plant via the canal. Our water starts its more than 200-mile journey atop the Sierra Nevada Mountains, and then it flows through the Sacramento-San Joaquin Delta before arriving in Pittsburg. We also have two groundwater wells in Pittsburg that produce approximately 10% of our water supply. While most of our water is drawn upriver, it is all treated, tested and distributed by your Pittsburg Water team.

Water quality report

The treated drinking water delivered to your home meets or exceeds all drinking water standards set by the state and federal governments.
