Western Municipal Water District (Western) has been committed to reliably serving the community for more than 60 years. Providing high-quality service to residents and businesses on a daily basis is our business. Customers depend on our highly skilled, multi-disciplined, and dedicated teams to provide sustainable water in a financially responsible and environmentally sensitive manner. On October 4, 2017, Western's Board of Directors adopted Resolution 2974 which establishes three years of water rates that cover the high cost of imported water supplies, as well as the cost to provide reliable service 24/7. These rates will be applied to water service billed on or after January 1, 2018, 2019 and 2020.
