As part of the Western Corridor Recycled Water Scheme, MWH, now part of Stantec, served as lead designer in the alliance that completed the design, construction, and start-up of the Gibson Island Advanced Water Treatment Plant (AWTP) in 2008.

    Location: Queensland, Australia
    Status: Complete

    The plant was originally designed to treat 13 mgd of secondary effluent from the Gibson Island wastewater treatment plant and was upgraded to 26 mgd midway through construction.  Treated water is pumped to Wivenhoe Reservoir, Brisbane’s primary source of drinking water, and used for power plant cooling, industrial purposes, and indirect potable reuse. The treatment process includes tanks; screens; pumping systems; high-rate ballasted clarification for removal of phosphorus; microfiltration; reverse osmosis; advanced oxidation using hydrogen peroxide and UV light; and chemical dosing systems for the main liquid stream.  MWH performed detailed paper, bench-scale, and pilot-scale analyses for nutrient management and disinfection byproduct formation.  The project was constructed under a design-build contract.
