This work at the Arlington Water Pollution Control Plant included the upgrade and expansion of the existing 10 MGD wastewater treatment facility through two contracts. Fru-Con Construction, acquired by Balfour Beatty in 2011, served as the general contractor for the wastewater plant’s upgrade. Major buildings and structures included a septage facility, screen and grit building, primary clarifiers, fine screen building, equalization valve room, carbon treatment building, UV disinfection building, plant waste basin and pump station, methanol building, chemical building, odor control fan building, pre-humidifying scrubber, outfall structure, electrical building and storage tanks.
Today, the Arlington Water Pollution Control Plant uses five wastewater treatment and solids handling systems to ensure that only treated water is discharged into County waters and the Chesapeake Bay. Through a successive process involving preliminary treatment, primary treatment, secondary treatment, tertiary treatment/chemical addition and solids treatment, the plant provides water that meets local and national purity standards.
