Most of our customers are supplied with water purchased from the City of Everett, and some customers are supplied by well water. The water purchased by the PUD from the City of Everett is filtered, treated and chlorinated to maintain purity. Fluoride is also added to the water. Treatment provided for the water systems supplied by wells varies depending on the characteristics of the well source. The PUD has full-time water supply specialists who assure your drinking water is safe to drink by routinely testing for bacteria and chemical impurities.
