Livermore Municipal Water was established in 1963 as part of the City of Livermore Water Resources Division. Today, Livermore Municipal Water provides drinking water service to approximately 1/3 of Livermore. Livermore Municipal Water's 23-square mile service area includes over 28,000 residential and commercial customers in the northern and eastern portions of Livermore.
Both Livermore Municipal Water and Cal Water receive their treated water from Zone 7 Water Agency. 80% of this water is from the California State Water Project, 10% is from Del Valle Reservoir, and 10% is local groundwater.
After water is treated by Zone 7 Water Agency, the water is delivered to five pump stations. The pump stations move the water to four reservoirs. These reservoirs provide billions of gallons of water for domestic, irrigation, and fire protection use annually.
All California water suppliers with more than 3,000 customers are required to prepare an Urban Water Management Plan every five years. Urban Water Management Plans help with long-term water resource planning to ensure that there will be adequate water supplies to meet future demands. The reliability and efficient use of water supplies are assessed over a 20-year time frame during normal, dry, and multiple dry year conditions.
If you are a Cal Water customer, visit their website to access the Cal Water Livermore District Urban Water Management Plan.
Water Shortage Contingency Plans identifies the actions that a water service provider will take if there are short or long-term water supply challenges. The plan identifies four conservation levels, each with their own voluntary or mandatory conservation measures to preserve the water supply.
