Blue Plains Influent Sewer Rehabilitation
Bryant provided construction management services for the rehabilitation of more than three miles of 10-ft. diameter influent sewers to the Blue Plains Advanced Wastewater Treatment Plant. The sewer pipes were between 30- to 100-years old and constructed of brick and concrete. Various sections of the pipe were deteriorated, exposing aggregate and reinforced steel; The majority of the sewer lines were located inside federal property (Bolling Air Force Base and the Naval Research Laboratory), therefore, extensive coordination was necessary.
As a prime consultant for the District of Columbia Water & Sewer Commission (DC Water), Bryant successfully managed the rehabilitation and structural repairs including: corrosion protection for pipe segments of the East and West influent sewers; modifications to several structures and manholes; a structure at the Poplar Point Pumping Station; and flow control during construction. The rehabilitation methods used included glass reinforced panels (GRP), sliplining, spiral wound (SPR), shotcrete, and epoxy coating. All consent decree dates were met throughout the management and construction of this extensive and complex project.
