California’s water supply is taxed by challenges such as drought, unsustainable groundwater use, and tensions over limited resources for a growing population. This Issue Brief, produced in collaboration with the Natural Resources Defense Council, finds that there is significant potential for improved efficiency and conservation in California’s urban water use, which accounts for one-fifth of the state’s total use. While educating water consumers and encouraging behavioral changes to reduce demand is critically important, this brief focuses on technological solutions to using water more efficiently. Taking all available steps towards water conservation and efficiency has long- and short-term economic, social, and ecological benefits for California.
