We are pleased to report: Our water is safe, clean and continues to outperform every state and federal water quality standard.
Every year, Moulton Niguel conducts approximately 12,000 water quality tests that are independently analyzed at state-of-the-art laboratories. Moulton Niguel staff work diligently to ensure that our drinking water complies with the science-based water quality standards set by the Environmental Protection Agency and the State Water Resources Control Board.
Moulton Niguel is committed to delivering high-quality water to every customer. We also believe in full transparency. The District publishes an annual Consumer Conﬁdence Report to provide our customers with all the data from our water quality testing.
This report, which covers water quality testing for the 2020 calendar year, includes a comprehensive summary of everything you need to know about your water. It provides details on the results of water quality tests conducted at each stage of treatment and delivery as well as information about the required safety regulations for public drinking water providers.
Over our 61-year history, Moulton Niguel has invested in building a robust water infrastructure system. We take great pride in delivering safe, clean, and reliable drinking water at the lowest water rates in South Orange County.

Have you ever wondered where your water comes from? Here in the Moulton Niguel Water District, our water is imported from both Northern California and the Colorado River.
Water from Northern California travels to us through a complex delivery system known as the California State Water Project. Designed and built in the 1960s, the State Water Project is one of the largest public water and power utilities in the world, providing drinking water for more than 27 million people statewide.
Managed by the California Department of Water Resources, the project stretches over 700 miles, from Lake Oroville in the north to Lake Perris in the south. Water stored in Lake Oroville, Folsom Lake, and other tributaries, and fed by snow melt from the Sierra Mountains, flows into the Sacramento and San Joaquin rivers, and from there into reservoirs in the Bay-Delta region.
From the Bay-Delta, giant pumps lift the water into the 444-mile-long California Aqueduct, there to flow southward to cities and farms in central and Southern California. Composed mainly of concrete-lined canals, the Aqueduct also includes over 20 miles of tunnels, and nearly 160 miles of pipelines. Along the way, the water is pumped 2,882 feet over the Tehachapi Mountains. The Edmonston Pumping Plant alone lifts millions of gallons a day up 1,926 feet, the highest single water lift in the world.
Managed by the Metropolitan Water District of Southern California, the Colorado River Aqueduct begins
near Parker Dam on the Colorado River. There, the Gene Pumping Station lifts the water over 300 feet, and it begins its 242 mile journey to Lake Mathews, just outside the City of Corona. Along the way, the water passes through two reservoirs, five pumping stations, 62 miles of canals, and 176 miles of pipelines.
All told, the water is lifted four times, a total of more than 1,300 feet. After its journey across the Mojave Desert, the water descends into the Coachella Valley and through the San Gorgonio Pass. Near Cabazon, the aqueduct flows underground, passing beneath the San Jacinto Mountains and continuing until it reaches its terminus at Lake Mathews. From there, 156 miles of distribution lines, along with eight more tunnels, delivers the water throughout Southern California.
