2015 Update

On September 5, 2017, the City Council conducted a public hearing and adopted, by Resolution R2017-116, the City of Napa's Urban Water Management Plan (UWMP) 2015 Update.  It is currently being reviewed by the California Department of Water Resources (DWR) for completeness.  As an urban water supplier serving more than 3,000 connections or 3,000 acre-feet annually, the City is required to submit an updated UWMP to DWR every five years.  The plan is a summary of City policies and procedures addressing water supply, demand, and conservation over the next 20 years.  The 2015 Update demonstrates the City's interim 2015 compliance with the Water Conservation Act of 2009 (SBx7-7) which seeks a statewide 20% reduction in urban per capita water use by 2020.  Supply and demand comparisons show excellent overall water service reliability, with no shortfalls projected through 2035 even in critical single-dry years.
