The State Water Project , also known as the California Aqueduct , transports water 600 miles (970 km) from Northern California to the southern portion of

900-679: The Imperial Irrigation District elected to not execute the DCP and the Metropolitan Water District agreed to provide the full portion of water storage contributions to Lake Mead. By the end of 2020, MWD will have nearly stored 1 million acre-feet in Lake Mead and contributing to 12 feet (3.7 m) of Lake Mead's elevation. The State Water Project moves water from the western Sierra Nevada through

950-730: The Orange County Groundwater Basin , and the Irvine and Lake Forest sub-basins. For many years, IRWD received almost all of its water from imported sources. To alleviate this dependency on expensive imported water, IRWD began to develop a series of local wells in 1979. The Dyer Road Wellfield Project extracts low-cost, high-quality water from deep within the Orange County Groundwater Basin. IRWD now operates 25 groundwater wells within its service area. Approximately 20 percent of IRWD’s water

1000-811: The Pacific Ocean . Urban runoff can be prevented by implementing efficient irrigation practices. Additionally, an urban runoff treatment system, like the IRWD Natural Treatment System program , helps protect the San Diego Creek Watershed by naturally removing some of the contaminants in from urban runoff before it reaches the ocean.

1150-472: The Colorado River Aqueduct's capacity was used, only 178,000 acre-feet (220,000,000 m ) of water. The San Diego County Water Authority joined Metropolitan as its first wholesale member agency in 1946. SDCWA was formed in 1944 to facilitate joining Metropolitan, received its first deliveries in 1947 and was buying half of Metropolitan's water by 1949. The SDCWA annexation broke two traditions at Metropolitan: Member agencies had previously been cities (SDCWA

1200-730: The Colorado River through deserts and over mountain ranges to its terminal reservoir, Lake Mathews , in Riverside County . The aqueduct system includes five pumping plants that lift the water 1,617 feet (493 m). IRWD produces approximately 21 percent of its supply by treating wastewater and reusing it for irrigation and other non-potable, or non-drinking, uses. The primary uses of recycled water are agricultural and landscape irrigation including parks, school grounds, golf courses, freeway landscaping and irrigation of common areas managed by homeowner associations. Recycled water

1250-852: The Delta. A minimum freshwater flow has to pass through the Delta in order to prevent salinity intrusion from San Francisco Bay , and the removal of freshwater from the Delta has also threatened multiple species, such as native chinook salmon . The Inland Feeder project added a direct tunnel and pipeline connection from Silverwood Lake to Diamond Valley Lake and was completed in 2010. The Metropolitan Water District of Southern California reservoirs store fresh water for use in Los Angeles, Orange, Ventura, Riverside, San Bernardino, and San Diego counties. These reservoirs were built specifically to preserve water during times of drought, and are in place for emergencies uses such as earthquake, floods or other events. Metropolitan maintains three major water reservoirs. One

1300-469: The District. Urban runoff is the excess water that carries pollutants into storm drains and then to the ocean. Residents who live miles inland can contribute to ocean pollution simply by leaving their sprinklers on too long. After this wasted water flows to the curb it carries trash, fertilizers, pet waste and other pollutants into the storm drain system which flows into San Diego Creek , eventually ending up in ecologically sensitive Upper Newport Bay and

1350-529: The Los Angeles Basin. The Colorado River Aqueduct begins at Lake Havasu , just north of Parker Dam , and travels 242 miles (389 km) west to Lake Mathews in southwest Riverside County. Water is first pumped 125 miles (201 km) uphill through a series of five pumping plants approaching Chiriaco Summit, then flows 117 miles (188 km) downhill towards Los Angeles. Metropolitan contracts for about 2 MAF/Y (million acre feet per year) from

The program includes 60 miles (97 km) of new pipelines to convey the treated water across four regional groundwater basins, an industrial facility, and two MWD treatment plants. The program calls for

1450-862: The Metropolitan set an all-time delivery record of 1,316,000,000 gallons of water in just a 24-hour period. Metropolitan's additional supplies and easier rules of entry facilitated an expansion through annexation of large areas of low populations: The eight MWDs that joined from 1946 to 1955 added 200 percent to Metropolitan's service area but only 75 percent to Metropolitan's population served. By 1965, Metropolitan had 13 cities and 13 municipal water districts as members. It covered more than 4,500 square miles (12,000 km ) and served some 10,000,000 people. By 2008 Metropolitan had 14 cities and 12 municipal water districts (San Fernando joined in 1973; MWDOC and Coastal MWD merged in 2001) and provided water to nearly 10,000,000 people. As of 2021 , Metropolitan with 26 member agencies and cities served nearly 19 million people in

1500-480: The San Francisco Bay to Southern California. As the largest of the now 29 agencies, Metropolitan contracts with the state Department of Water Resources, which owns and operates the State Water Project, for slightly less than half of all supplies delivered to Metropolitan.

2100-467: The need for IRWD to purchase more expensive sources of water, such as imported water from the Metropolitan Water District of Southern California. In an attempt to ensure equity among its customers, the IRWD separates the cost of building water and sewer infrastructure from the cost of daily operations and maintenance. Infrastructure costs, called capital projects, are financed through general obligation bonds,

2150-477: The need for dramatic increases in customer rates to pay for new infrastructure (pipes, pumps, reservoirs, etc.) or for the inevitable repair and the replacement of these types of facilities as they begin to age. Public agencies such as IRWD do not issue a traditional annual report, but rather a much fuller report called a Comprehensive Annual Financial Report or CAFR. The report highlights major projects and initiatives in addition to financial data. The CAFR has been

Southland residents voted for a major bond in the depths of the Great Depression to fund the construction effort through the desert to deliver essential water supplies and generate badly needed jobs. The post-World War II boom and 1950s dry spells prompted

2500-421: Was in charge of issuing bonds and financing their repayment by selling water to member agencies. In the early years, revenue from water sales was too low, so Metropolitan also collected taxes that ranged from 0.25 to 0.50 percent of assessed value. Ninety percent of the cost of the aqueduct has been paid for by the taxpayers. In 1929 the district was set up with an area of 600 square miles (1,600 km ) and served
