Project

As part of a long-term effort to reduce basement backups, sewer overflows, and to improve creek bank stabilization, MSD Project Clear is constructing a project to replace approximately 4,000 feet of sewer and stabilize approximately 210 feet of a natural creek in the City of Chesterfield.

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. 

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.
