Operations & Maintenance


With more than 600 employees working throughout our service area, Operations comprises nearly 2/3 of MSD’s total staff. Charged with operating and maintaining seven treatment plants, approximately 279 pump stations, and over 9,600 miles of wastewater and stormwater sewers, our crews in the field are supported by our expert customer service call center, fleet repair services, warehouse services, and asset management team.

Our mission is to protect the public health, safety, and water environment by effectively operating and maintaining MSD’s wastewater and stormwater infrastructure.

Often, Operations serves as the public face of MSD. Our crews are the ones you see in your neighborhood inspecting, cleaning, and repairing the sewers. We transport and treat wastewater and return it safely to local rivers. We work for the community to make it a better, cleaner, and safer place to live. Not only are we employees, many of us are MSD customers with a vested interest in properly handling the wastewater and stormwater in our service area and doing so in an efficient and cost-effective manner.

System maintenance and rehabilitation is critical to MSD Project Clear’s commitment to quality customer service and to MSD’s mission statement “to protect the public’s health, safety, and water environment by responsibly providing wastewater and stormwater management.”

Force mains are pressurized pipes that move material using pumps. Their repair and maintenance is a top priority of MSD Project Clear. All pipes degrade over time and eventually need repair, rehabilitation, or replacement, among other activities; therefore, MSD Project Clear is focusing efforts on force main inspection and repair.

MSD Project Clear responds to emergencies throughout the service area. The emergency team aims to respond to 90% of 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.
