Sources Of Supplies

Metropolitan's integrated resources planning strategy calls for a portfolio approach to water resource management that balances imported water with local supplies. Metropolitan imports water from Northern California via the State Water Project and from the Colorado River via the Colorado River Aqueduct. About 45% of Southern California's water supply comes from these two sources. Southern California relies on various local sources to make up the difference. To ensure adequate supplies for the region, Metropolitan invests in local resource development along with its member agencies and utilizes groundwater banking and transfer program. Metropolitan also manages water demands by promoting and investing in conservation and water use efficiency projects. Southern California's future water supply will largely come from new local supplies such as recycled water and desalination.
