Projects

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is constructing a project to install approximately 10,000 feet of undersized sewers in the city of St. Louis.

What is the goal of this project?

MSD Project Clear is investing approximately $4,862,108 to improve wastewater sewers in the city of St. Louis. The goals are separate stormwater sewer from wastewater sewer and connect the stormwater sewer to already constructed mitigation basins.

Project Facts

• Construction is estimated to begin as early as Summer 2024
• MSD Project Clear will construct approximately 10,000 feet of pipe
• The pipe size will be 12 to 48-inches in diameter, allowing a larger amount of water to flow through the system

What can residents expect?

This project will be constructed using “open-cut” construction. Open-cut construction is when MSD’s contractor will put the pipe in by digging through the surface of the ground in a process known as “open-cut” construction. The pictures above depict what a neighborhood will look like before, during and after a typical open-cut project.

With any type of construction, residents can expect to see and hear heavy equipment during the sewer excavation process.

Traffic and Access: As some of the construction will take place in the street, residents should expect temporary lane closures. MSD Project Clear will maintain at least one lane of traffic at all times to allow residents to enter and exit.

Similarly, construction may lead to temporarily limited access to some properties along the construction route. Restrictions will be limited to active construction hours, and the contractor will notify property owners in advance of any access restrictions.

Restoration: After all new sewer pipes are installed, the contractor will restore the construction site according to all MSD and local requirements. This could include sodding any disturbed areas, replacing disturbed pavement, reinstalling fences, etc.

At least one MSD Inspector will be on-site part of the day for every day the contractor is working.

What is the timeline?

This is the current tentative project schedule. This is subject to change based on a variety of factors, including weather.

• Estimated construction start: Summer 2024
• Estimated project duration: 24 months
