The city, in consultation with the association and the offices of emergency services in Alameda County, Santa Clara County, and San Mateo County, shall prepare an emergency response plan describing how water service will be restored to the area served by the bay area regional water system after an interruption caused by earthquake or other natural or manmade catastrophe, and
thereafter shall be implemented.
(b)
During any interruption in supply caused by earthquake, or other natural or manmade catastrophe, a regional wholesale water supplier shall distribute water to customers on an equitable basis, to the extent feasible given physical damage to the regional water system, without preference or discrimination based on a customer’s geographic location within or outside the boundary of the regional wholesale water supplier.

(b)
In order to supply adequately, dependably, and safely the requirements of all users of water, the city shall continue its practice of operating the reservoirs in the
Counties of Tuolumne and Stanislaus in a manner that ensures that the generation of hydroelectric power will not cause any reasonably anticipated adverse impact on water service. The city shall assign higher priority to delivery of water to the bay area than to the generation of electric power, unless the Secretary of the Interior, in writing, notifies the city that doing so would violate the Raker Act (63 P.L. 41). The city shall make available to the public, on request, its plans of operations (rule curves) for these reservoirs.

obligations under this division at the time the ownership and control of the bay area regional water system are transferred to that district.
Cal. Water Code - WAT § 73510. Section 73510.

The wholesale customers of regional wholesale water suppliers other than the city are responsible for reimbursing the regional wholesale water supplier for their proportionate share of those costs,
through the imposition of water charges.
