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. 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 City of Napa Water Division is actively seeking proposals from consultant teams with expertise in multiple disciplines including fisheries, watershed monitoring, reservoir management for protecting water quality and preventing invasive species, HEC-RAS modeling, and more. Proposals are due Thursday, November 17, 2016.
The Governor first declared a Drought State of Emergency in January 2014, encouraging all Californians to take personal actions to reduce water demand. In 2015, with record low snowpack in the Sierra Nevada mountains, the Governor issued additional Executive Orders mandating statewide reductions in urban water use. Under the adopted regulations, the City of Napa was required to reduce its total water consumption by 20% for the period of June 2015 through May 2016 (compared to 2013 levels). Together, we beat the target, saving 1.2 billion gallons! With improved water supply conditions in Northern California this year, the State Water Board has allowed urban water suppliers to establish conservation standards based on their own local circumstances. As a result of our local Water Supply Reliability Certification, the City is no longer subject to a percentage savings mandate as of June 2016. As we transition back to our long-term water efficiency goals, 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. Keep in mind that the State Water Board has retained statewide regulations to prohibit water waste and the City is enforcing for all customers:
