The Creve Coeur Creek Trunk Sewer project will alleviate basement backups and sewer overflows along Creve Coeur Creek in southeast Chesterfield. Improvements include replacement of older smaller wastewater pipes with new larger pipes in order to increase the capacity of the wastewater system between Baxter and Schoettler (see map).

Project Area

Project Facts

  • Construction of 7,750 feet of 12 to 24-inch new wastewater pipe
  • Removal of a constructed sewer outfall that currently discharges into a nearby stream during heavy rainfall
  • Investment = $9-10 million (estimate to be refined through further study)

How will this impact residents?

Impact on property owners during the design phase is minimal. Residents may notice field crews visiting the area as they compile information needed for design.

Greater impacts can be anticipated during construction, which is anticipated to begin in 2019.  The project team is working closely with the City of Chesterfield to minimize impacts and keep residents informed.

The project will eliminate a sanitary sewer overflow into Creve Coeur Creek.
Field crews study the project area to finalize design.
