The San Diego Aqueduct is a system of four aqueducts in the U.S. state of California, supplying about 70 percent of the water supply for the city of San Diego.[1] The system comprises the First and Second San Diego Aqueducts, carrying water from the Colorado River west to reservoirs on the outskirts of San Diego. The 70-mile (110 km) First Aqueduct consists of pipelines 1 and 2, which run from the Colorado River Aqueduct near San Jacinto, California, to the San Vicente Reservoir, approximately 15 miles (24 km) northeast of the city. Pipelines 3 and 4 make up the 94-mile (151 km) Second Aqueduct. Together, these four pipelines have a capacity of 826 cubic feet per second (23.4 m3/s). The smaller, 12.5-mile (20.1 km) Fallbrook-Ocean Branch branches from the First Aqueduct into Murray Reservoir. The La Mesa-Sweetwater Branch originates from the First Aqueduct, flowing into the Sweetwater Reservoir.[2]

For decades, 95% or more of the region's water flowed through the water authority's connection with MWD. Today that share is down around 70%, with desalination and water recycling coming on line.
