San Diego Completes Pure Water Pipeline: Eight Miles of Steel in the Ground, 30 Million Gallons a Day Bound for Miramar Reservoir
The City of San Diego, in San Diego County, California, announced on November 4 that the final piece of pipe for the North City Pure Water Pipeline has been installed underground on Hoyt Park Drive in Scripps Ranch, completing more than eight miles of underground pipeline. Once active, the line will carry 30 million gallons of purified water per day from the North City Pure Water Facility in Sorrento Valley to Miramar Reservoir.
The $182 million project, begun in 2021, includes eight miles of 48-inch steel pipeline and fiber-optic infrastructure, six tunnels and one railroad bridge crossing, plus a new de-chlorination facility near Miramar Reservoir and about one mile of underwater pipeline inside the reservoir to distribute the purified water. It is one of 12 major construction projects in Pure Water Phase 1, the largest infrastructure undertaking in the city's history. With the final segment in place, crews will commission and test the system, and in the coming months will finish curb ramps, repaving and restriping along the route.
Mayor Todd Gloria said Pure Water was the largest and most consequential infrastructure commitment in San Diego's history when he took office, and that a promise on paper is now eight miles of steel in the ground, producing 30 million gallons locally every day and reducing dependence on imported supplies. Public Utilities Director Drew Kleis called the pipeline the critical link to Miramar Reservoir and thanked residents and businesses along the route for their patience. When fully built out in 2035, Pure Water is expected to supply nearly half of San Diego's local water. (Source: City of San Diego)
