irrig season mini2014 DROUGHT:  In January, the Governor declared a Drought State of Emergency for California, and in April called on citizens to redouble their efforts to conserve water.  With a goal of reducing personal water usage by 20 percent, check out the Save Our Water campaign for some great tips on What We Can Do, and be sure to take advantage of the local programs detailed below.  For the months of March through October, water usage in Napa was down 13 percent compared to last year.  This was our lowest irrigation season usage in 20 years, since 1994, when the population was 12,000 fewer and extensive hotel development had yet to occur.  We urge customers to continue this great progress by turning off automatic irrgation systems during the winter.  Use our Drought Survival Guides: Lawns, Trees & ShrubsMulch.

The State Water Board has adopted statewide emergency regulations to prohibit water waste and the City is required to enforce locally:

Water use efficiency (a.k.a. water conservation) is an integral part of the City of Napa's long-term water management strategy.  As a signatory to the Memorandum of Understanding Regarding Urban Water Conservation in California, the City is committed to implementing the appropriate Best Management Practices (BMPs) to ensure future supply reliability.  To comply with the Water Conservation Act of 2009 (SBx7-7), the City is working to reduce demand below 132 gallons per capita per day (gpcd) by 2020.  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!

sow logoFrom 1997 to 2002, demand on our water system averaged 170 gpcd.  Since 2003 when the City began to implement more California BMPs, demand has averaged about 150 gpcd, including a low of 139 gpcd in 2011.  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 financial incentives and educational opportunities:

Water-Wise Landscaping 

Nearly half of Napa's treated drinking water is used outdoors, much of it wasted in overwatering lawns and gardens.  Like only 2% of the world, Napa has a Mediterranean climate, with cool, wet winters and summer droughts.  Selecting appropriate plants, mulching, and frequently adjusting irrigation to match the weather are just a few of the actions you can take to save water in your landscape.
