PMI received the ACEC Engineering Excellence Award (Water Resources Category) for the Recirculating Media Filter Treatment project. PMI designed wastewater treatment plant improvements for the Riviera Utilities facility that services the Diamondhead, AR community. The design incorporated much of the existing infrastructure, including conversion of the existing intermittent sand filters to recirculating media filters. By utilizing an attached growth system, the long-term O&M costs are significantly less than a mechanical plant. The plant has been in compliance with all effluent limitations since construction.

PMI’s Brad Wingfield, PE, accepted the award along with Jack Plumlee and Leny Baker of Riviera Utilities at the ACEC Awards Gala on March 8th.
