Water must be used efficiently.
6. Local Supplies. Local water supplies, which usually are the most dependable, least costly, and most drought resistant resources available to a local community, must be carefully managed and protected for sustainable use by the community.
7. Conservation. Conservation is constitutionally mandated and often is the least environmentally damaging way of achieving efficiency in water use. The constitutional prohibition against waste must be fully implemented.
8. Reuse. Reuse of highly treated wastewater must be encouraged for a wide variety of uses including potable reuse, provided water quality is protected. Wastewater is now cleaned to near potable standards, and then most of it is thrown away.
9. Groundwater management. The groundwater and surface water within a basin or watershed are typically physically connected, and must be managed using whole system management approaches. In order to protect instream flows and terrestrial habitat, controls on overdraft should be instituted immediately. Ultimately, means should be found to reduce or eliminate groundwater overdraft.
10. Watershed Management. Watershed management plans shall be developed to maximize coordination of all government agencies and the public to achieve multiple benefits, including but not limited to capturing stormwater where it falls, recharging the groundwater, improving water quality, and restoring wildlife habitat. The beneficiaries of exported water shall be required to invest in watershed restoration.
