Cal. Wat. Code § 13956.5
The Legislature further finds and declares that the people of the state have a primary interest in the development and implementation of programs, devices, and systems to conserve water so as to make more efficient use of existing water supplies and to reclaim wastewater in order to supplement present surface and underground water supplies. Utilization of reclaimed water and water which has otherwise been conserved will economically benefit the people of the state, will augment the existing water supplies of many local communities, and will assist in meeting future water requirements of the state. It is therefore further intended by the Legislature that the state undertake all appropriate steps to encourage and develop water conservation and reclamation so that such water may be made available to help meet the growing water requirements of the state.
