Valley Water provides wholesale treated water to retailers, raw surface water to a select group of customers, and manages local groundwater basins. Groundwater and surface water users rely on their own equipment to access those supplies.

- 如果PG＆E在Santa Clara County of Shout Off Powers作为其社区野火安全计划的一部分，我们对我们的供水潜在影响是什么？
Valley Water has always had contingency plans in place to continue to deliver treated water and make groundwater available to our water retailers in the event of a power outage. Valley Water has built the necessary back-up power resources into its infrastructure. Permanent generators are connected to critical Valley Water facilities, which includes all the drinking water treatment plants, the water quality lab and multiple administration buildings. Valley Water also has several mobile generators of various sizes that can be quickly deployed to the field, where they may be needed. Our generators are also tested and maintained on a regular basis to be ready for service in case of an unplanned outage.
- In the event of an extended outage, how many days can Valley Water continue water delivery service using back-up power resources?
Several factors are involved in determining how long Valley Water can continue treated water delivery service, including time of year and water demand. In the event of the unlikely possibility of a total power loss throughout Santa Clara County, we have enough fuel on-site to run the generators for approximately four to six days. We also have contracts with fuel suppliers that could supplement our needs if necessary to extend our operations using backup power.
Valley Water receives federal water from San Luis Reservoir and state water from the South Bay Aqueduct. The pumping plants providing water to Valley Water from San Luis and the South Bay Aqueduct have no back-up power. Some water from Lake Del Valle could be delivered by the South Bay Aqueduct via gravity, but Valley Water would primarily rely on in-county surface water from Anderson and Calero Reservoirs to provide the raw water to the treatment plants, as available at the time.
A key mission of Valley Water is ensuring local groundwater supplies are reliable. Groundwater basins in Santa Clara County can store vast amounts of water, much more than all ten surface water reservoirs combined. Because of this, these groundwater basins are the primary reserve that retailers draw upon more heavily during droughts or other emergencies. Our activities to replenish groundwater, deliver treated water, and conserve and recycle water help make sure local groundwater is reliable and available.
Pumps to extract water from wells typically rely on electricity for power. In those cases, the pump will not work during a power outage unless it is connected to an alternate source of power, like a generator. PG&E has several resources for what to do before, during and after aPublic Safety Power Shutoff, including how to选择合适的发电机和发电机安全提示.
