Cole Creek CSO 204 Sewer Separation, Phase 4


In conjunction with the Phase 3 study area, the Phase 4 study began in September 2017 to evaluate the alignment and sizing of the proposed storm and sanitary sewers in the area bounded by Sprague Street on the North, 52th Street on the East, Maple Street on the South, and North 57th Street on the West. This was accomplished to coordinate the correct sizing, alignment and depth of the proposed sewers.

The Final Design for the Phase 4 area is anticipated to begin in 2020 and be completed in 2022.

Project Description

The Cole Creek 204 Sewer Separation project is a multi-phase project located in a 522 acre basin referred to as Cole Creek 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.

The Phase 4 design includes a combination of new sanitary and storm sewers throughout the area. Improvements to local storm sewers may address localized street flooding.

Project Benefits

This project is Phase 4 of approximately six planned phases that will convert the existing combined sewers to separated sewers. It will ultimately result in reduced sewer backups into area homes and reductions in combined sewer overflow volume and flow rate in Cole Creek.
