The Water Division of the Utilities Department is responsible for the operation, maintenance, and improvement of the municipal drinking water system serving 87,000 people in the City of Napa and adjacent areas. The Water Division is dedicated to providing a safe and reliable supply of high-quality drinking water for its residential, commercial, industrial, and institutional customers. A comprehensive review of the City’s water system is contained in the Urban Water Management Plan. The Plan describes and evaluates water supply sources, projected demand, water conservation, and overall water service reliability through 2035.
We are OPEN! The Utilities Department will be open Monday through Thursday, from 8 am to 5 PM, and will be physically closed to the public on Fridays. However, the community will still be able to access staff and services either by phone or by appointment, depending on services requested.
We respectfully ask that all visitors to our facility please wear a mask when indoors, as the safety of our community and our staff is of the utmost importance.
