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, Arkansas community. The design incorporated much of the existing infrastructure, including the existing intermittent sand filters, which were converted to recirculating media filters. Utilizing an attached growth system significantly reduced the long-term O&M costs of 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.
