As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is constructing a project to replace approximately 10,000 feet of undersized wastewater sewers in the cities of Warson Woods, Ladue, Kirkwood, Rock Hill and Glendale. In addition, approximately 140 feet of natural creek will be stabilized to reduce creek bank erosion and improve water flow.
This project is estimated to begin construction in January 2024.

A number of residents have experienced building back-ups, mainly due to overcharged sewers that cannot handle the increased amount of flow experienced during rainfall.
In addition, the sewer system in this area uses old technology called overflow points where untreated wastewater is discharged into waterways during heavy rainfall to prevent the water from backing up into buildings. There are three of these overflow points that need to be removed in this area.
MSD Project Clear is investing approximately $13 million to improve wastewater sewers and prevent creek bank erosion by installing concrete lining and rock stabilization in the cities of Warson Woods, Ladue, Kirkwood, Rock Hill and Glendale. The goal is to reduce basement backups and sewer overflows, which occur when the sewers become overloaded during intense rainfall. This project will reduce such occurrences by increasing the size and capacity of the existing sewer. In addition, the creek in this area is experiencing erosion and this project will stabilize the creek bank to improve water flow and protect some of the nearby private properties from creek erosion. It will also allow MSD to eliminate 3 sanitary sewer overflow points.
Some 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. However, for the majority of this project, tunneling will be used to avoid major traffic implications.
This project will be constructed by digging through the surface of the ground in a process known as “open-cut” construction. The pictures below 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 the street, residents should expect temporary lane closures on Des Peres Avenue, Warson Woods Drive, Glen Elm Drive, Glenway Drive, Alexandra Avenue, Alexandra Drive, Belson Court, and Brownell Avenue. MSD Project Clear will maintain at least one lane of traffic at all times to allow property owners to enter and exit. Traffic control will be provided as needed.
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.
