As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is replacing approximately 4,140 feet of sewer in South County generally along Christopher Drive and Nellie Avenue in Unincorporated St. Louis County.

About the Project

Public Meeting - May 6, 2021

Project Map

Why is this project being constructed?

MSD is investing $1.11 million into this neighborhood with this project to reduce sewer overflows and clean up our local waterways.

Our team of engineers determined that the sewer in this neighborhood deteriorated and in need of repairs. The deteriorated condition makes this sewer subject to breakages which cause sewer overflows in this area. Repairing this sewer will reduce sewer overflows, leading to cleaner creeks, streams, and natural environment.

How will it be built?

MSD’s contractor will determine the most appropriate method of construction based on traffic, access concerns, and utility interference. Most of the project will likely be constructed by digging through the surface of the ground in a process known as “open-cut” construction. The contractor may use tunneling for portions of this project in which they lay pipe with minimal disruption to the surface.

How will this affect residents?

Because the majority of construction will take place in backyards quite a distance from homes, construction should minimally affect traffic and property access.

While the contractor is replacing the sewer at Becker Road, traffic may be reduced to one lane. MSD will have a traffic mitigation plan to ensure residents maintain access to their homes.

Some residents may experience temporary access restrictions to their driveways. The contractor will give all property owners ample notification prior to access restrictions and will ensure access during non-working hours.

With any construction, residents can expect to see and hear heavy equipment during the sewer excavation process. The pictures above depict what a neighborhood will look like before, during, and after a typical project.

At least one MSD Inspector will be on-site part of the day for every day the contractor is working.

When will construction take place?

This project is currently delayed due to an industry-wide material shortage. At this time, we do not have an anticipated start date. We will update this page with more information as soon as it becomes available. If you would like to receive email updates about the project timeline, please sign up here.

What will it look like when it's done?

After the contractor installs all new pipes, they will restore the construction site according to all local and District requirements. This could include sodding disturbed areas, replacing disturbed pavement, reinstalling fences, etc.

MSD will not replace plants, ornamentals, or other items in the construction easement or public right of way. Residents who wish to keep such items should move them before construction starts.

FAQs

This section will be updated with questions as we receive them. Have any more questions? Contact the Project Manager.

Trees may need to be removed to construct parts of this project. MSD will work with an arborist to evaluate all of the trees along this project. If there are good options to avoid removing trees, MSD will make every attempt to do that.

Property owners with trees that will need to be removed that are not located in already existing easements will have been compensated for the removal through the easement acquisition process.

MSD does not anticipate sewer service or other utility services being disrupted during this project. We will work with Missouri One Call to locate utilities before beginning construction. Occasionally, the contractor may run into utilities that were not located by Missouri One Call which could result in temporary utility disruptions. If this happens, MSD will work with the utility to restore service as quickly as possible.
