The Cole Creek 204 Sewer Separation Project*is a multi-phase project located in a 522 acre basin referred to as Cole Creek CSO 204. It is bordered on the north by Brown Street, on the east by 52nd Street, on the south by Northwest Radial Highway, and on the west by Cole Creek.
Phase 4 is located on the southeast portion of the Cole Creek CSO 204 basin. The downstream portion of the CSO 204 Phase 4 Project will discharge (connect) to the Cole Creek CSO 204 Area, Phase 3 Combined Sewer Separation (Taylor to Ruggles between 56th and 61st) Project facilities that will be completed in 2022.
This project will convert the existing combined sewers within the project limits to either storm or sanitary sewer. Additionally, new separate sanitary or storm sewers will be constructed to provide a separated sewer system within the project limits. This will ultimately result in reduced sewer backups into area homes and reductions in combined sewer overflow volume and flow rate to Cole Creek, improving its water quality.
Additional benefits of the CSO 204 Phase 4 Project include:
Preliminary design is in progress for Phase 4a and 4b, with 30% design documents expected in early 2023.
