Projects

As part of a long-term effort to reduce basement backups and sewer overflows, MSD[3] Project Clear[1] is constructing a project to replace approximately 2,835 feet of undersized wastewater sewers. In addition, this project will reduce creek bank erosion and improve water flow by stabilizing 852 feet of natural creek in the City of Chesterfield.

About the Project

What is the goal of this project?

MSD Project Clear is investing approximately $1.5 million to improve the wastewater sewers and prevent creek bank erosion in the City of Chesterfield. The goals are to reduce basement backups and sewer overflows, which occur when the sewers become overloaded during intense rainfall, and prevent creek bank erosion by installing rock stabilization to protect some of the nearby private properties from creek erosion.

Project Facts

• Construction is estimated to begin in Spring 2023.
• MSD Project Clear will replace approximately 2,835 feet of wastewater pipe.
• The pipe size will increase to between 8 and 15-inches in diameter, allowing a larger amount of wastewater to flow through the system.
• MSD Project Clear will also install approximately 852 feet of natural channel stabilization.

What can residents expect?

This project will be constructed 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. In the segments crossing Still House Creek Road, the contractor will use tunneling to avoid major traffic implications. With any type of construction, residents can expect to see and hear heavy equipment during the sewer excavation process.

Traffic and Access: As much of the construction will take place in unpaved areas, MSD anticipates minimal traffic disruptions. Drivers may experience temporary lane closures as construction crosses roadways and will see increased construction traffic. Traffic control will be provided as needed.

The contractor will follow all local ordinances and will notify all properties of any temporary access restrictions. As the majority of construction will take place in backyards, MSD anticipates minimal property access restrictions. The contractor will give all property owners ample notification prior to 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: Spring 2023
• Estimated project duration: Approximately 9-12 months
