The Water Division is responsible for the operation, maintenance, and improvement of the municipal water system serving more than 86,000 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 (UWMP). The Plan describes and evaluates water supply sources, projected demand, water conservation and water shortage contingency programs, and overall water service reliability through 2035. The latest UWMP update is being finalized and is scheduled for Public Hearing at the City Council Meeting on Tuesday, July 18. A draft will be made available for public review by July 1.
DROUGHT OFFICIALLY ENDED:
With Executive Order B-40-17 on April 7, 2017, the Governor officially terminated the Drought State of Emergency first declared in January 2014, but statewide water waste prohibitions remain in effect. Napa has been practicing conservation and becoming more efficient in its water use over the past two decades. Thanks to this longstanding conservation and our reliable water supplies, state-mandated water use reductions had not been required for the City after May 2016, and are now removed for all of California. It is prudent to be efficient and use our precious water resources wisely; however, the 25% decrease in demand during the drought has resulted in reduced revenue available to operate, maintain, and invest in our water system. Although water rates have historically been based primarily on the volume consumed, which is variable, many system costs are fixed, such as maintaining the extensive infrastructure necessary to treat and deliver water to customers. Proposed changes to how our water is billed will be considered by City Council during the summer of 2017.
As we transition back to long-term water efficiency goals and address the state's new plan for Making Water Conservation a California Way of Life, please visit our Water Conservation section for local water-saving ideas, including generous rebate programs, and get some great tips from the Save Our Water campaign. Again, please note that although this drought is over the State Water Board has retained statewide regulations to prohibit water waste and the City is enforcing for all customers:
