Emergency Water Use Restrictions

On May 9, 2016, Governor Brown issued Executive Order B-37-16, requiring the State Water Resources Control Board (SWRCB) to adjust its emergency water conservation regulation through the end of January 2017 in recognition of the differing water supply conditions across the state. The newly adjusted regulation places responsibility on each local water supplier to calculate its own conservation standards for customers based on a “stress test,” which requires them to prove they have sufficient water supplies to withstand three years of continuous drought, or take additional measures that include mandatory conservation targets. Water suppliers that fail to meet these new conservation standards may still face enforcement from the SWRCB. 

On June 21, the city of Patterson submitted water demand and supply projections for the next three years. Based on these projections, staff made recommendations to City Council to adjust the 25% conservation standard to 10% and modify the current drought designation of Stage II to a Stage I water shortage. These actions were approved by the City Council on July 19, 2016. As a result, the city will be increasing the number of days for outdoor water use from two days to three days a week. A copy of the self-certification submittal can be viewed below.
