Public Meeting - September 22, 2020
UPDATE: Construction start pushed back to May 3, 2021. At the time of the below recorded meeting, the contractor planned to begin construction in the Fall of 2020; however, construction was delayed as the contractor waited for other utilities to relocate their assets in the construction path. The new construction start date is May 3, 2021. At this time, we do not have an updated anticipated completion date, but we will update this page as more information becomes available.
About the Project
Why is this project being constructed?
MSD is investing $1.57 million into this neighborhood with this project to alleviate basement backups and clean up our local waterways.
As part of our agreement with the Environmental Protection Agency (EPA) and the Missouri Coalition for the Environment, MSD is committed to removing points in our system where untreated wastewater can overflow into local waterways. These points are known as Sanitary Sewer Overflows, or SSOs. This project will allow MSD to remove two SSOs, helping to ensure wastewater is cleaned by one of our seven treatment plants before returning to the environment.
In addition to creating cleaner creeks and streams, the new sewer will also reduce the likelihood of basement backups for residents and businesses in this neighborhood.
How will it be built?
The majority of this project will be constructed by digging through the surface of the road, in a process known as “open-cut”.
How will this affect residents?
Because much of the construction takes place in the roadway, customers may experience lane and road closures. However, MSD will have a traffic mitigation plan to ensure residents have access to homes and businesses, and at least one lane of traffic will remain open at all times.
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 is the current tentative project schedule. This is subject to change based on a variety of factors including weather.
- Estimated construction start: Delayed
- Estimated construction completion: November 3, 2021
- Second Public Meeting: September 2020
- Design completion: June 2018
- Easement acquisition: July 2018-July 2019
- First Public Meeting: June 2018
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.
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.
MSD’s contractor will use gravel to fill around the pipe and will backfill the rest of the trench with the existing soil.
With most wastewater pipe replacement projects, it is best for the new pipe to be installed at or below the depth of the existing pipe. To avoid Gravois Creek, the new pipe at the south end of the project (near Grant’s Trail) will be installed approximately 3 feet deeper than the existing pipe.
If the contractor removes a fence during construction, they will reinstall or replace the fence according to the easement agreements.
