Cal. Wat. Code § 81435
The agency may impose reasonable rates, fees, and charges on Stanford University, the California Water Service Company, and the agency's member public entities for any program or service provided or work performed by the agency. The agency may also impose reasonable rates, fees, and charges on any other public or private entity that enters into a contract with the agency for use of any program or service provided or work performed by the agency. These rates, fees, and charges shall be at least sufficient to generate revenue to pay the principal and interest on any bonds issued by the agency to carry out the work. The agency shall be solely responsible for servicing the debt on any bonds it issues and the State of California has no responsibility for those bonds.
