Water Conservation

Water use efficiency and conservation form an integral part of the City of Napa's long-term water management strategy. The City has worked to keep system demands low and is now looking ahead to Making Water Conservation a California Way of Life. For our customers this means we are available to help you make every drop count, and every drop you save will reduce your own water bill.

From 1997 to 2002, demand on our water system averaged 170 gallons per capita per day (gpcd). Since 2010, demand has averaged just 130 gpcd, including a low of 114 gpcd in 2016. This trend results from the evolution of water-efficient appliances, City ordinances and programs, and water recycling. We look to continue this progress by offering our customers a variety of conservation tips, financial incentives, and educational opportunities.
