On-water activities will be available again at the City of San Diego’s Miramar Reservoir beginning Saturday, July 6, following the successful installation of a new underwater pipeline as part of the Pure Water Program.


On-water recreational activities at Miramar Reservoir were suspended beginning in September 2023 to allow for the installation of a 1-mile-long branched pipeline to be installed on the bottom of the reservoir. Following the completion of this significant project, boats, canoes, kayaks and float tubes are welcome once again.


“We thank San Diegans for their patience during this important construction project for our local water supply,” said Juan Guerreiro, Director of the City’s Public Utilities Department. “We are happy to welcome back residents and visitors for all recreational activities at the reservoir.”


Purified water produced at the North City Pure Water Facility will flow through 8 miles of underground pipeline before reaching the subaqueous branched pipeline that will distribute the water throughout the reservoir. Pure Water San Diego is the City’s phased, multi-year program that will provide nearly half of our water supply locally by 2035. Pure Water will use proven purification technology to clean recycled water and produce safe, high-quality drinking water. The program offers a cost-effective investment for San Diego's water needs and will provide a reliable, sustainable water supply.


The largest integrated infrastructure project in the City’s history, construction on Pure Water Phase 1 is just over 55% complete with 10 major construction projects underway across the City. When complete, Phase 1 will produce an annual average of 30 million gallons per day of purified water. Phase 2, now in the planning stages, will produce an additional 53 million gallons a day.


Miramar Reservoir is one of nine reservoirs owned and operated by the City that are part of the City's municipal water-supply system. It is open daily to the public from sunrise to sunset.
