As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is constructing a project to replace approximately 12,600 feet of undersized wastewater sewers in the cities of Ladue and Olivette.
This project is estimated to begin construction in the fall of 2026.
MSD Project Clear is investing approximately $13 million to improve wastewater sewers in the cities of Ladue and Olivette. The goals are to reduce basement backups and sewer overflows, which occur when the sewers become overloaded during intense rainfall. It will also allow MSD to eliminate 4 sanitary sewer overflow points.
Though construction for this project is not estimated to begin until Fall 2026 at the earliest, it is important to be prepared for what to expect. While much of the construction will take place in existing easements, MSD may need to obtain new easements from some property owners. Prior to construction, residents whose property will need to be accessed to construct the project will be contacted to obtain the necessary easements or to be notified of work that will take place in existing easements.
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. However, for some of this project, tunneling will be used 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 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.
This is the current tentative project schedule. This is subject to change based on a variety of factors, including weather.
