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 3,300 feet of undersized wastewater sewers in the city of Ellisville.

About the Project

What is the goal of this project?

MSD Project Clear is investing approximately $3,095,000 to improve wastewater sewers in the city of Ellisville. 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 as early as Fall 2024
• MSD Project Clear will replace approximately 3,300 feet of wastewater pipe
• The pipe size will increase to between 8 and 15-inches in diameter, allowing a larger amount of water to flow through the system.

What can residents expect?

This project will be constructed using both tunneling and “open-cut” construction. Tunneling will be used for crossing Clarkson Road to reduce traffic impacts. 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 on Field Avenue, Clarkson Pines Lane and Hunter’s Glen Court. 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: Fall 2024
• Estimated project duration: 16 months
