Livermore Municipal Water

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.

Central and southern Livermore receive their water service from California Water Service (Cal Water). Click here for a map showing water service providers in the Tri-Valley. 

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.

Urban Water Management Plan

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.
