Untreated Water Rates for CY 2017

Wholesale Water Rate Study


How does Zone 7 Impact Your Water Rates?

More than 80 percent of Zone 7's water supply starts as Sierra snowmelt and is imported to the Valley from the State Water Project using the Delta and South Bay Aqueduct for conveyance. Zone 7 either stores it in the local groundwater basin for later use, or treats the water for delivery to your local water retailer as drinking water. In turn, your retailer -- the City of Pleasanton, the City of Livermore, Dublin San Ramon Services District or the California Water Service Company -- delivers the water to you, factoring in its own cost of service before sending you the final bill.

Rates for untreated water are based on the cost of acquiring the untreated water, Bay-Delta related costs and an adminsitrative fee based on staff costs.
