Metropolitan built and maintains a water supply system that is the cornerstone of the region’s $1 trillion economy. As the nation’s largest municipal water provider, Metropolitan owns and operates five separate treatment plants, among the largest in the world. The district’s complex network of pipelines and facilities consistently delivers high quality water to its 26 member agencies in its 5,200 square mile service area. Rigorous maintenance and regular capital investments ensure Metropolitan’s customers benefit from reliable service and advancements in water supply and water quality technology, including state-of-the-art treatment upgrades.
Originally established to bring imported water to Southern California, today Metropolitan collaborates with its member agencies to develop new local supplies and invests in both conservation and water use efficiency to reduce water demands throughout the region. Metropolitan is also investing in research and planning for additional water resources to ensure adequate supplies for the region’s economic growth and prosperity.
