Edmundson Sanitary Relief (12159)
As part of a long-term effort to reduce basement backups and sewer surcharging, MSD Project Clear is designing and constructing approximately 3,000 feet of wastewater sewer through the Edmundson Sanitary Relief project. The project is located in the Cities of Woodson Terrace, Breckenridge Hills and Unincorporated St. Louis County. The project will be north of St. Charles Rock Road and west of Woodson Road.
This project is currently in the Design Phase. The Consultant selected for this project is Wood PLC. Construction is scheduled to begin in Fall 2023 with an anticipated duration of 30 months.
Design Neighborhood Meeting
What is the goal of this project?
MSD Project Clear is investing approximately $2.5 million to design and construct this project to ultimately alleviate instances of building backups and allow the wastewater system in this neighborhood to carry more wastewater flow. More than 3,000 feet of larger, newer wastewater sewer and 390 feet of stormwater sewer will be installed. This project is estimated to benefit 470 properties.
- Construction is estimated to begin Fall 2023.
- Construction is estimated to last between 30 months.
- MSD Project Clear will install approximately 2,400 feet of wastewater sewer.
- The pipe size will range from 8 to 18-inches, allowing a larger amount of wastewater to flow through the system.
- Approximately 150 feet of stormwater sewers will be relocated.
What can residents expect?
Though construction for this project is not estimated to begin until Fall 2023, it is important to be prepared for what to expect. By Spring 2023, 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 vast 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. In areas with utility conflicts, traffic control issues, or general access concerns, the contractor will likely use tunneling, which allows them to lay pipe with minimal disruption to the surface.
As a part of this project, MSD Project Clear does expect traffic impacts to roads in this area. Temporary road closures are expected but the construction crews will work diligently to keep these closures during work hours. One lane of traffic will be maintained at all times. 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. Currently the following roads are estimated to have traffic impacts due to this project: Corregidor Drive, Bataan Drive, Harold Drive, Kathlyn Drive, Edmundson Road, Chesterve Avenue, and Muriel Avenue. Temporary lane closures may be required.
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 and provide notice beforehand.
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.
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: November 2021
- Easement acquisition completion: Spring 2023
- Estimated construction start: Fall 2023
- Estimated project duration: 30 months
For the most part, yes. However, there may be temporary disruptions when sewer construction crosses driveway entrances.
There may be temporary disturbance of these features. MSD’s contractor will restore fences and mailboxes as necessary and replace disturbed vegetation with new sod.
