MSD crews respond to overflows after widespread power outages in the Chesterfield area


CHESTERFIELD, Mo. – Saturday night’s storms caused several power outages throughout the St. Louis area which have led to overflows in sewers and creeks.

The Metropolitan St. Louis Sewer District (MSD) said some of its pump stations in the Chesterfield area lost power, resulting in overflows into the Caulks and Bonhomme Creeks.

MSD is advising the public to avoid contact with these creeks until power is restored and cleanup efforts are complete in the following areas:

  • Caulks Creek, in a wooded area west of Crystal Spring Drive
  • Bonhomme Creek, along the Monarch Chesterfield Levee trail behind Chesterfield Commons
  • Other portions of Bonhomme Creek east and north of I-64

MSD pump stations in this area have redundant power feeds. However, due to the widespread nature of the outage, those redundant feeds could not be utilized to keep them in service. MSD crews are working on bringing power generators onto the pump station sites to bring the stations back into service while Ameren Missouri crews work to restore power service to the area. Sewer service was not affected.

Warning signs have been posted in the area advising the public of the overflow. While there is no immediate threat to public health or safety, everyone is asked to avoid physical contact with Bonhomme and Caulks Creeks through the week. Anyone who comes in contact with wastewater should immediately and thoroughly wash with soap and water.

MSD has reported the break to The Missouri Department of Natural Resources.

Sean Hadley, manager of public affairs for MSD, said many of these problems will be addressed Monday after a thorough assessment.

“We did see some overflows from several different pump stations, which we will have to do an assessment and probably do a clean up tomorrow, where the overflows are, and make sure they’ve ceased,” Hadley said. “For the most part, they’ve all been stopped and most of the stations have power back to them now.”
