Pure Water Oceanside Advanced Water Purification Facility

Pure Water Oceanside is the first operating advanced water purification project in San Diego County. A new Advanced Water Purification Facility (APWF) will produce 4.5 MGD of fully advanced treated recycled water (under Phase 1), with provisions to expand an ultimate minimum production capacity of 6.0 MGD (under Phase 2).

Pure Water Oceanside will purify recycled water using state-of-the-art technology that replicates and accelerate nature’s natural recycling process. The three purification steps are ultrafiltration, reverse osmosis and ultraviolet light advanced oxidization. Minerals are added before the water is injected into the Mission Basin, where it will blend with the naturally occurring groundwater and recharge the aquifer. The water is then extracted and treated again at the Mission Basin Groundwater Purification Facility and finally distributed to customers in the City.

Under this contract, Shimmick will construct nitrification-denitrification (NDN) facilities and Plant 2 blower improvements, as well as a new AWPF process building, with a process feed tank, pump station and strainers, ultrafiltration, reverse osmosis, ultraviolet light advanced oxidation, stabilization, product water pump station and connection to conveyance piping. Shimmick will also install a waste equalization wet-well and pump station and pipeline to plant headworks. A new reverse osmosis concentrate pipeline connection to the secondary effluent pump station and chemical storage and feed facilities as well as other site work.

Shimmick is self-performing more than 80 percent of the work which includes civil and site work, structural and concrete, yard piping, mechanical and electrical and start-up and commissioning.
