Hawthorne Estates Sanitary Relief (12299)

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is designing a project to construct approximately 1,800 feet of wastewater pipe in the City of Town and Country. The project is estimated to begin construction as early as the Winter of 2025.

About the Project

Public Meeting - April 6, 2023

Project Map

Why is this project being designed?

MSD Project Clear is investing approximately $1.5 million to improve the wastewater sewers in the City of Town and Country. The goal is to reduce basement backups and sewer overflows, which occur when the sewers become overloaded during intense rainfall. MSD Project Clear has received 6 such complaints. This project will reduce such occurrences by installing a new relief sewer to increase the capacity of the wastewater system in the area.

Project Facts

  • Construction is estimated to begin as early as Winter of 2025
  • MSD Project Clear will install approximately 1.800 feet of new 12-inch diameter wastewater relief pipe, allowing a larger amount of water to flow through the system

What can residents expect?

Though construction for this project is not estimated to begin until the Winter of 2025 at the earliest, it is important to be prepared for what to expect. While much of the construction will take place in existing easements, MSD may need to obtain new easements from some property owners. Prior to construction, residents whose property will need to be accessed to construct the project will be contacted to obtain the necessary easements or to be notified of work that will take place in existing easements.

Type of Construction:

At this time, MSD Project Clear anticipates the contractor will primarily construct the project by digging through the surface of the ground in a process known as “open-cut” construction. As 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.


As much of construction will take place in the street, residents should expect temporary lane closures. MSD Project Clear will maintain at least one lane of traffic at all times to allow residents to enter and exit.

Similarly, construction may lead to temporarily limited access to some properties along the construction route. Restrictions will be limited to active construction hours, and the contractor will notify property owners in advance of any access restrictions.

Repair and Restoration:

After all new sewer pipes are installed, the contractor will restore the construction site according to all easement agreements and 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.

  • Estimated construction start: As early as Winter of 2025
  • Estimated project duration: 12-18 months


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.

For properties without an existing easement, an MSD Right of Way Agent will work with property owners during the easement acquisition process to discuss restoration on their property.

For properties with an existing easement, MSD will restore the area following District policies. Most yard and wooded areas will be replanted using sod or seed and straw. Driveways, walkways, and other hard surfaces will be restored using the same materials that are currently in place.

Streets that are disturbed during construction will be replaced and repaved with similar material. The project’s restoration will meet all local and District requirements.
