    About Our Presentation

    The $310 million Groundwater Replenishment System (GWRS) Final Expansion Project will bring the Orange County Water District’s Advanced Water Purification Facility to its build-out treatment capacity of 130 million gallons per day.

    To complete this final expansion, the treatment capacities of the microfiltration system, the reverse osmosis system, and the ultraviolet light systems will need to be increased to treat secondary effluent from Orange County Sanitation District (OCSD). In addition, a new pump station, flow equalization tanks, and a pipeline will need to be constructed at OCSD’s Plant No. 2 in Huntington Beach.

    The secondary effluent from OCSD’s Plant No. 2 brings a new water quality to the GWRS facility and with it some design challenges for water recycling. Also, as part of the GWRS Final Expansion Project, non-reclaimable wastewater flows from the upper watershed will be separated at OCSD’s Plant No. 2 headworks in order to not recycle these flows through GWRS.

    The GWRS Final Expansion Project is currently in construction and an overview of construction activities completed to date will be given. Additional planned upgrades to the overall GWRS facility will be addressed as well – these upgrades are required to prepare for the new GWRSFE project treatment capacity of 130 million gallons per day.

    Plan now to join us January 20 for an insightful look at one of the major projects underway in the County today. You won’t want to miss this.
