About the
Tri-Valley Water Partners

The Tri-Valley Water Partners are a collaborative effort between the region’s water wholesaler, Zone 7 Water Agency and local water retailers, California Water Service (Cal Water), City of Livermore, City of Pleasanton, and Dublin San Ramon Services District, to address our collective water needs now and for future generations. In the Tri-Valley, Zone 7 Water Agency serves as the wholesale water provider, securing and importing water for the region, managing the local groundwater basin, and treating water at its two treatment plants. Residents in the cities of Livermore, Pleasanton, Dublin, and Dougherty Valley then receive that water directly to their taps.

Together, these agencies work to ensure the Tri-Valley area has a reliable water supply, now and in the future!
