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, Phase 3 Project facilities that are to be constructed in 2021.
This project is phase 4 of approximately four planned phases that will convert the existing combined sewers to either storm or sanitary sewer plus providing additional capacity with new sewers. It 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 Cole Creek CSO 204 Sewer Separation, Phase 4 Project include:
Field work in advance of design is underway for the Phase 4a and 4b Projects. Conceptual design deliverable is anticipated in spring 2022.
