As part of the PURE program to upgrade San Diego’s water treatment system, Shimmick was the $356 million contract to construct the new North City Pure Water Facility. This new state-of-the-art facility will treat San Diego’s recycled water (currently used for irrigation) from the North City Water Reclamation Plant to purified water standards, making it suitable as a potable water source. Shimmick will construct the new facility near the existing water reclamation plant. The treatment plant will include ozonation, biological activated carbon filters, membrane filtration, reverse osmosis, and ultra-violet light with advanced oxidation. The new facility will be able to produce up to 30 million gallons per day of purified water. Via pipeline, the water will be stored in the Miramar Reservoir, until it is further treated at the Miramar Water Treatment Facility and distributed for use.
