The Water Division is responsible for the operation, maintenance, and improvement of the municipal water system serving more than 85,000 people in the City of Napa and adjacent areas.  The 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 water shortage contingency programs, and overall water service reliability through 2035.

HYDRANT FLUSHING:  Due to ongoing drought conditions, the City is deferring the full hydrant flushing program that was planned for 2014.  This program is important in maintaining water quality however, and it is likely that some select areas will be flushed later this year to comply with water quality mandates.  Affected areas will be notified, and all efforts will be made to minimize water used.
