Glenfield Sanitary Relief (12264)

Glenfield Sanitary Relief (Watson Woods Ct to S Lindbergh Blvd) (12264)

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is designing a project to replace undersized sewers in the City of Sunset Hills near South Lindbergh Boulevard and East Watson Road.

This project is estimated to begin construction in Spring 2023.

Project Map

What is the goal of this project?

MSD Project Clear is investing approximately $2 million to design this project to increase the size and depth of the existing sewer to increase the capacity of wastewater the pipes in this neighborhood can handle.  This will alleviate existing problems resulting from undersized sewers, like overloaded sewers.

Project Facts

  • Construction is estimated to begin Spring 2023.
  • MSD Project Clear will replace approximately 2,600 feet of wastewater sewer.
  • The pipe size will increase to between 8 to 15-inches in diameter allowing a larger amount of wastewater to flow through the system.

What can residents expect?

Though construction for this project is not estimated to begin until Spring 2023, it is important to be prepared for what to expect. By the Fall of 2022, residents whose property will need to be accessed to construct the project will be contacted in order to obtain necessary easements.

Type of Construction:

While the exact methods of construction will be determined as the project moves towards the Construction phase, just like with any type of construction, residents can expect to see and hear heavy equipment during the sewer excavation process.

The majority of this project will be constructed by a method known as “open-cut construction”. This means that crews will dig through the surface of the ground to excavate and install pipe. To cross South Lindbergh Boulevard, crews will be “tunneling” underneath the road.  This means that a a tunnel boring machine will be lowered into the ground to dig through the soil and rock. Tunneling is being used in this area to minimize disturbance of the surface of South Lindbergh Boulevard and minimize impacts to traffic.

Traffic Impact: 

As a part of this project, MSD Project Clear does expect traffic impacts to roads in this area. Construction near and on Watson Woods Court, Eggeling Lane, Woodpark Drive, Woodfox Drive, South Lindbergh Boulevard, and Chrisann Lane will require temporary lane closures. There will also be impacts to area parking lots at 3808, 3778, 3826, 3844, and 3811 South Lindbergh Boulevard. More specific information including timing and locations of these closures will become available once the project has a Contractor and they can determine a set schedule.

MSD Project Clear does expect times of temporarily reduced access for residential and commercial properties throughout the construction of this project. However, these timings will be temporary and the Contractor will work to minimize these instances.

Restoration:

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. More detail on this will become available after a Contractor is selected for the project ahead of construction in the Spring of 2023.

What is the timeline?

This is the current tentative project schedule. This is subject to change based on a variety of factors including weather.

  • Project design completion: Fall 2021
  • Easement acquisition completion: Fall 2022
  • Estimated construction start: Spring 2023
  • Estimated project duration: 24 months

FAQs

In accordance with MSD policy, the Contractor will restore all disturbed surfaces to previous or better conditions.

The Contractor will be committed to minimizing any instances of access issues to residential or commercial property.
