Project Detail
  • Blue Plains Wastewater Treatment Plant

    Washington, DC, USA

    Xypex products used: Admix C-500

    The District of Columbia’s massive Blue Plains Advanced Wastewater Treatment Plant covers 150 acres and treats approximately 370 million gallons of water per day, making it one of the largest in the world. During their 2009 expansion, the owner, DC Water, emphasized their efforts to ensure the below grade system would remain dry. As a result, they decided to specify Xypex Admix in a slurry wall to provide additional waterproofing.

    The slurry wall sections are over 30-in. deep and 18-in. wide. The concrete, designed to be flowable, incorporates pea gravel as the aggregate. The wall forms were filled with water at the time of the pours and then the water was displaced as the concrete filled the cavity. The project used Admix C-500 in soluble bags for just over 15,000 cubic yards of concrete.

    The completed system addition, to be operational in 2015, brings a 1930’s facility into the 21st century.
