Louisville and Oakland Sewer Relief (Project #12741)

Louisville and Oakland Sewer Relief (Project #12741)

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is replacing approximately 1,800 feet of sewer in the City of St. Louis. The Louisville and Oakland Swewer Relief project will increase the size of the combined sewer which will reduce basement backups and prevent sewer overflows in this area.

Construction was originally scheduled to begin in June of 2022 with anticipated completion in the Summer of 2023. This project is delayed due to conflicts with relocated other utilities. MSD will update this page with a new timeline when it becomes available.

About the Project

Public Meeting - June 14, 2022

Please note that the schedule for this project has been pushed back since the recording of this meeting. Please find the most up-to-date schedule information below under “When will construction take place?”

Project Map

What work is being done?

  • MSD Project Clear is replacing and upsizing approximately 1,000 feet of sewer.
  • The pipe size will increase to 12 to 36-inches in diameter allowing a larger amount of water to flow through the system.
  • MSD Project Clear is also installing approximately 800 feet of 96-inch diameter pipe as additional underground storage. This will add additional capacity during rain events and reduce the likelihood of basement backups and sewer overflows.

Why is this project being constructed?

MSD is investing approximately $2,580,000 into this neighborhood with this project to alleviate basement backups and clean up our local waterways.

As part of their evaluation, our team of engineers determined that the sewer in this neighborhood is undersized. During intense rainfall, the sewers become overloaded, leading to basement backups and wastewater overflows into local waterways.

How will it be built?

MSD’s contractor, Gershenson Construction Company, will install the pipe 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. They will work section-by-section and will fill completed sections with gravel or cover it with a steel plate to reduce traffic disruptions.

How will this affect residents?

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.

Because much of the construction takes place in the roadway, customers may experience lane restrictions or temporary road closures during working hours. Street parking will be unavailable during construction. MSD will have a traffic mitigation plan to ensure residents have access to homes and businesses.

During the time that MSD’s contractor is disconnecting a property’s lateral from the current sewer pipe and reconnecting it to the new pipe, they may ask customers to limit water use. In general, this process can take between two to five hours, depending on the complexity of the connection. The contractor will notify property owners in advance.

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.

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 as MSD works with other utilities to relocate their assets that conflict with the construction path. We will update this page with a revised schedule when it is available.

Previous milestones:

  • First neighborhood public meeting: September 2019

What will it look like when it's done?

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

During the time that MSD’s contractor is disconnecting a property’s lateral from the current sewer pipe and reconnecting it to the new pipe, they may ask customers to limit water use.

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.

Street parking will be unavailable during construction. During active construction, some property owners may experience driveway access restrictions for a short period of time. The contractor will notify property owners in advance of any temporary access restrictions to allow them time to move their vehicles. The contractor will also fill trenches with gravel or place steel plates over trenches during non-working hours so property owners can use their driveways during those times.

Trees may need to be removed to construct parts of 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. If you have questions about specific trees, please contact Mark Dietiker at mdietiker@stlmsd.com or (314) 768-6380.
