Projects

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is constructing a project to replace approximately 3,600 feet of undersized wastewater sewers in the City of St. Ann.

Due to unforeseen issues with this project, the project was paused but is expected to restart in mid-late April. This will push the completion date to late 2024.

About the Project

What is the goal of this project?

MSD Project Clear is investing approximately $2.3 million to improve wastewater sewers in the City of St. Ann. The goals are to reduce basement backups and sewer overflows, which occur when the sewers become overloaded during intense rainfall.

Project Facts

• Construction is estimated to begin in Fall 2023.
• MSD Project Clear will replace approximately 3,600 feet of wastewater pipe.
• The pipe size will increase to between 18 and 30-inches in diameter, allowing a larger amount of wastewater to flow through the system.

How will it be built?

The majority of this project will be constructed by digging through the surface, a process known as “open-cut.” The contractor will dig a trench several feet into the ground, remove the old sewer pipe, and replace it with a newer, larger pipe.

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. 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 paved areas, MSD anticipates traffic disruptions for “through traffic”. Drivers will 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.
