Regional Recycled Water Supply Program Advisory Panel

Metropolitan and the Sanitation Districts of Los Angeles County are working collaboratively to develop a potential regional recycled water supply program that would purify and reuse water for recharge of groundwater basins in Southern California. An advisory panel of key subject matter experts has been established to provide independent review and critical input on the scope and direction of the program during its demonstration project phase. In this initial effort, the panel will provide input into the development of the program's feasibility and financial assessments, as well as the design of the 1MGD demonstration plant.
