Drought status and water supply

Drought-O-Meter-Between-StepItUp-and-CutItBackLatest drought news

In response to decreasing statewide water supplies, California is banning the watering of ornamental grass for commercial customers as of June 1, 2022. The ban does not include turf at residences or turf used for recreation or community purposes. This mandate will affect Western's commercial customers.

Additionally, The Metropolitan Water District of Southern California is requiring that more than 6 million people in parts of Los Angeles, San Bernardino, and Ventura counties—who rely on state water from northern California -- restrict outdoor watering to just one day per week due to rapidly worsening drought conditions. This mandate DOES NOT currently apply to Western customers. 

Western's water supply and response actions 

Western relies on water imported from Northern California; however recent customer investments have created local supply and storage at Diamond Valley Lake that is getting us through for now. But, we need all customers to do their part to step it up and slow your water flow. Using less water now may help prevent mandatory water use restrictions later. 

Western remains in Stage 2 – Water Supply Alert status of its Water Shortage Contingency Plan (WSCP), which calls for a voluntary 20 percent water use reduction. Customers should reduce water use by 20%, particularly outside, where more than 60 percent of residential water is used. 

If the State or The Metropolitan Water District of Southern California requests future mandatory reductions, Western will look at implementing an administrative and/or drought fine policy as a tool to encourage efficient water use.

We encourage you to get familiar with your water bill, learn about your water budget and review your water usage each month. Western has a variety of customer support tools and programs to help you use water efficiently. Learn more by visiting, wmwd.com/Rebates
