How Will a Stormwater Disconnection Impact Me?


Project Clear will include significant investments in new sewer systems underground. These improvements will help the system carry more wastewater to MSD’s treatment plants. After proper treatment, this clean water then goes back into the region’s rivers and streams.

To get Project Clear under way, field personnel working on behalf of MSD will be visiting some neighborhoods in our region to assess the condition of the sewer system.

field_personelField personnel working for Project Clear all carry photo identification and will wear yellow or orange safety vests. You may see them along the streets or in yards checking manholes, drains, and other connections to the sewer system. Never hesitate to ask our team members for their identification; or feel free to call us at (314) 768-6260 to inquire whether workers are in your area.

Q: Why is my area included/not included?
A: In many cases, it is most cost-effective to remove stormwater connections in areas where there are two sets of pipes – one for wastewater and one for stormwater – called a separate sewer system. Most of St. Louis County is served by such a separate sewer system. The City of St. Louis, however, is served by a combined sewer system, where wastewater and stormwater share the same pipe; different solutions are needed in these areas.

Q: If stormwater is entering the wastewater sewer on my property, how much will repairs cost me?
A: MSD will cover all costs, and will schedule the work on your property as part of an ongoing capital improvement program. There is no cost to a property owner to make the change. Solutions are being designed now and will be scheduled for construction in the coming years.

Q: How do I know if my downspouts, sump pump, sewer cleanout or drains are connected to the wastewater sewer?
A: It can be difficult to tell. Stormwater sources should discharge to your yard or to a stormwater collection point – typically a curb or a stormwater catch basin in the street.
