Conway Village Sanitary Relief (12131)

As part of a long-term effort to reduce basement backups and overcharged sewers, MSD Project Clear is replacing undersized wastewater sewer in the City of Town and Country.

MSD Project Clear will increase the size of the sewer system in this neighborhood. This will increase the capacity the system can handle and reduce basement backups in this area. Also as a part of this project, creek bank protection will be installed.

Why is this project being constructed?

MSD has invested over $1.9 million into this neighborhood to construct this project to increase the capacity of the sewer system and minimize the instances that the system becomes overcharged and backs up in to basements.

How will it be built?

The majority of the project will occur behind the houses off Conway Village Drive, alongside the creek that runs through the neighborhood.

The majority of the project will be built by digging through the surface of the ground to a depth between 8 and 22 feet, in a process known as “open-cut” construction. Crews will excavate the ground first and then lay almost 3,500 feet of new, bigger wastewater sewer.

A smaller portion of the project, approximately 540 feet, will be placed by using the “tunneling” method in two locations. In this method, a boring pit is excavated into the ground where a Tunnel Boring Machine is lowered to tunnel through the earth approximately 15 to 20 feet underground so as not to disturb the surface of a high traffic roadway. One tunnel will be bored under Interstate-64 and the other will be under Conway Village Drive.

How will this affect residents?

As with any major construction project, residents in this neighborhood can expect to see and hear heavy construction equipment.

Roads where open-cut construction will be used may be reduced to a single lane. Trenches installed in streets will be backfilled with rock. Normally trench backfill occurs soon after the pipe is installed so the traffic lane will be drivable shortly after the sewer is installed. Except for very narrow streets, one lane of traffic will be open except when the contractor is loading the excavated soil into trucks.

The contractor will follow all local ordinances and will notify all properties of any temporary access restrictions. In areas where open-cut construction will be used, there will be periods when driveways may be inaccessible. The contractor will give all property owners ample notification prior to any access restrictions.

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.

Project design completion date: 11/27/2019
Easement acquisition completion: 9/24/2019
Estimated construction start: November 2020
Estimated construction completion: Summer 2021

What will it look like when it's done?

In general, District policy is to restore affected areas to the same or better conditions than before the project. Streets that are disturbed through this project will be replaced and repaved with similar material. The project’s restoration will meet all requirements of the City of Town and Country.

Areas of restoration of yards disturbed by construction not located in existing easements have already been negotiated with property owners. Most yard areas will be resodded with the same material. In wooded ground areas, District policy is to seed the disturbed areas.

The Contractor will work diligently to restore disturbed surfaces to previous or better conditions. If you have questions about timing of restoration, please contact the Project Manager.
