As Southern California's population and economy continues to grow, the need for additional water to meet new demands will grow with it. Local resource programs such as water recycling, desalination, and groundwater recovery and storage, which are detailed in Metropolitan's Integrated Resources Plan​ are important assets in the region's diverse local resource portfolio, and help bring greater water supply reliability to Southern California. These resources, along with other local programs, help offset imported water supplies. Local water agencies have largely led the development of water recycling and groundwater recovery projects with many new projects incentivized by Metropolitan's Local Resources Program.
