About the Project

What is the goal of this project?

MSD Project Clear is investing approximately $17.3 million to improve the wastewater sewers in the city of Ladue. The goal is to reduce basement backups and sewer overflows, which occur when the sewers become overloaded during intense rainfall. MSD Project Clear has received multiple complaints. The project will reduce such occurrences by increasing the size and capacity of the existing sewer.

Project Facts

• Construction is estimated to begin as early as Summer 2025
• MSD Project Clear will replace approximately 11,400 feet of wastewater pipe.
• The pipe size will increase to between 8 and 48-inches in diameter, allowing a larger amount of water to flow through the system.

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 some areas, 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 back yards, residents should only expect temporary lane closures on Trent Drive. 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.
