Saylesville Sanitary Relief (12200)
About the Project
Public Meeting - July 27, 2021
What work is being done?
- MSD Project Clear is replacing of approximately 4,000 feet of wastewater pipe.
- The pipe size will increase to 8 to 18-inches in diameter allowing a larger amount of wastewater to flow through the system.
- MSD Project Clear will also stabilize approximately 210 feet of natural creek bank.
Why is MSD designing this project?
MSD Project Clear is investing approximately $3 million into the sewers in the City of Chesterfield with this project to alleviate basement backups and clean up our local waterways. The Saylesville (12200) project will increase the size of the wastewater sewer which will reduce basement backups and prevent sewer overflows in this area.
Additionally, this project was merged with an identified and budgeted stormwater capital improvement project to stabilize some creek bank erosion along Boxford Court, promoting the health of the natural water environment and protecting the nearby private properties from future creek erosion.
How will it be built?
The majority of this project will be constructed 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.
To reduce traffic disruptions on other streets, the contractor will tunnel under Saylesville Drive
What can residents expect?
With any type of 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.
TRAFFIC: Because some of the construction takes place in the roadway, customers may experience lane restrictions or temporary road closures during working hours. MSD will have a traffic mitigation plan to ensure residents have access to homes and businesses.
PROPERTY ACCESS: 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.
RESTORATION: After all new sewer pipes are installed, the contractor will restore the construction site according to all local and District requirements. This could include sodding any 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.
What is the timeline?
This is the current tentative project schedule. This is subject to change based on a variety of factors, including weather.
- Design phase completion: July 2021
- Easement acquisition: Summer 2021
- Estimated construction start date: Early 2023*
- Estimated construction duration: Approximately 18-24 months
*Anticipated construction start date is subject to change. MSD will notify residents before beginning construction.
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.
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 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.
