Water Division

COVID-19 Update:
Clean, safe, reliable drinking water service continues.
Utilities Department offices are closed to the public.
Lake Hennessey Boat Dock is closed until further notice.

  • Your water is safe to drink. Providing drinking water to the community is an essential service and the City of Napa is committed to the uninterrupted delivery of water during this challenging time. Our existing water treatment and disinfection processes keep your water safe from bacteria and viruses, including coronavirus.
  • During the Shelter-at-Home Order, you will continue to see City water utility employees performing critical services to operate and maintain the water system. Staff will follow CDC and Napa County Public Health guidelines while working in the community, including social distancing. Continuing activities include:
    • water treatment plant operations
    • emergency leak repairs of public water mains
    • necessary maintenance of tanks, pump stations, valves, fire hydrants
    • legally required water quality sampling in neighborhoods (hundreds of locations)
    • meter reading and urgent customer service calls (staff will not enter homes)
  • We will avoid shutting off water for normal maintenance activities. In the event of an unforeseen leak or other unexpected issue causing interruption in service, our highest priority is to fix the problem and restore water service as quickly as possible.
  • The main Utilities Department office at 1700 Second Street and the Corporation Yard on Jackson Street are closed to the public until further notice. Please call 707-257-9521 8:00 am-5:00 pm weekdays for staff assistance over the phone or to make an appointment. For after-hours emergencies, call 707-253-4451.
    • Trucked water filling at the Corporation Yard is suspended until further notice. As an alternative, call 707-257-9508 to request a hydrant meter. Expect some delays in processing due to limited staffing at City Hall.
  • The water bill payment center inside City Hall is closed. Payments can be made via mail, the drop box in front of City Hall (955 School Street), or online. If you have questions about your bill, please call 707-257-9508. There will be no water shutoffs due to delinquent payment during this emergency.

City of Napa Water looks forward to resuming full services as soon as the emergency order is lifted. We appreciate your patience and urge all customers to adhere to Shelter-at-Home guidelines.
