Eagle Creek Combined Sewer Overflow (CSO) Abatement
Citizens Energy Group
Eagle Creek’s CSO was put in place to collect additional rainwater and industrial waste water into one set of piping, as to transport them to a treatment facility to be treated and released into the Eagle Creek Reservoir.
This project included providing cast-in-place structures at the Eagle Creek Combined Sewer Overflow facility that will convey flow to the drop shafts for the tunnel. The work included supporting existing sewers, installing several precast manholes, 48’’ reinforced concrete piping approximately 25’-30’ below grade, and construction of a new park & playground. Due to the necessary depths, significant earth retention and dewatering systems were required. Additionally, Wilhelm provided a significant amount of traffic maintenance on nearby streets and business-lined sidewalks, paving and park renovations.
