Creve Coeur Creek Trunk Sewer

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.
