Urgent Issues & MSD's Emergency Response

Urgent issues include raw sewage found inside or outside of the house, missing manhole covers, and flooded streets. Our emergency team aims to respond to 90% of urgent service calls within four hours. If you experience a basement backup or see a sewer overflow, blocked stormwater inlet, or suspect damage to a sewer pipe, please don’t hesitate to reach out to MSD customer service at (314) 768-6260. They may dispatch an investigator to discover whether MSD has the ability to alleviate the situation.

Response During Heavy Rainfalls

During especially heavy rainfall, we may receive hundreds of phone calls and must prioritize our response according to the immediate threats to community health and safety. Because of our limited resources, it may take from a few hours to a few days before a crew responds. In most cases, crews will not need to enter the customer’s home or business to respond to the complaint.

We also follow up on reports of non-urgent cave-ins and settlements, typically within a few weeks.
