This project was split into two phases to coordinate construction activities with the City of Omaha's 72nd & Maple Transportation Intersection Improvements. Phase 2 final design is underway, with 90% plans anticipated late 2021.
The Cole Creek CSO 202 Sewer Separation, Phase 1 and 2 Project includes construction of both sanitary and storm sewers to provide sewer separation to 101 acres in the area.
This project is located in the Cole Creek Basin and is bounded on the north by Bedford Avenue; on the east by 67th Avenue; on the south by Lake Street; and on the west by 72nd Street or Cole Creek. Project construction includes both sanitary and storm sewer to allow for conversion of the existing combined sewer to either storm sewer or sanitary sewer. The primary objective of the Cole Creek CSO 202 Sewer Separation Project is to separate combined sewers in the area, reduce basement back-ups and potentially deactivate CSO 202 without increasing the stormwater discharge to Cole Creek.
This project will reduce the amount of stormwater entering the existing Cole Creek Sanitary Interceptor during storm events and maintaining capacity in the interceptor for the conveyance of sanitary flows. It will ultimately result in reduced sewer backups into area homes and reductions in combined sewer overflow volume and flow rate in Cole Creek.
