The Cole Creek CSO 202 Sewer Separation, Phase 1 and Phase 2 – 70th Avenue & Spencer Street Projects include construction of both sanitary and storm sewers to provide sewer separation to 101 acres in the area.
The projects area is located in the Cole Creek Basin; 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. The primary objective of the 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.
As a result the amount of stormwater entering the existing Cole Creek Sanitary Interceptor during storm events will be reduced and capacity for the flow of sanitary sewage will be maintained. Ultimately, sewer backups into area homes and combined sewer overflow volumes into Cole Creek will be reduced.
This project was split into two phases to coordinate construction activities with the City of Omaha's 72nd & Maple Transportation Intersection Improvements.
Phase 1 is complete.
Phase 2 – Final design is in progress; 90% documents are complete. This project is now on-hold pending utility relocation efforts with an expected construction start of spring 2024.
