Hathaway Drive Sanitary Relief (13432)

Hathaway Drive Sanitary Relief (13432)

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is designing a project to replace undersized sewers in the City of Jennings on Hathaway Drive between Jennings Station Road and Lewis and Clark Blvd. Woods has been selected as the Design Consultant for this project.

This project is estimated to begin construction in 2023.

About the Project

What is the goal of this project?

MSD Project Clear is investing approximately $1 million to improve the wastewater sewers in the City of Jennings. The goal is to reduce basement backups and sewer overflows by increasing the size and capacity of the existing sewer.

Project Facts

  • Construction is estimated to begin 2023
  • MSD Project Clear will replace approximately 1,000 feet of wastewater sewer
  • The pipe size will increase to between 8 to 10-inches in diameter allowing a larger amount of wastewater to flow through the system

What can residents expect?

Though construction for this project is not estimated to begin until Spring 2023, it is important to be prepared for what to expect. By the Summer of 2022, MSD will contact residents from whom easements are required to construct the project. MSD will not contact residents who have existing easements on their property

Type of Construction:

While the exact methods of construction will be determined as the project moves towards the Construction phase, just like with any type of construction, residents can expect to see and hear heavy equipment during the sewer excavation process. The majority of this project will be constructed by a method known as “open-cut construction”. This means that crews will dig through the surface of the ground to excavate and install pipe. To minimize disruptions to adjacent properties and aid in constructability, MSD’s contractor will use tunneling between 9200 Hathaway Drive and 9432 Auburn Drive. The contractor will dig two pits on either side of this section and use a Tunnel Boring Machine to lay the pipe underground with minimal surface disruption.

Traffic Impact: 

As a part of this project, MSD Project Clear does expect traffic impacts to roads in this area. Construction on Hathaway Drive will require temporary lane closures. More specific information including timing and locations of these closures will become available once the project has a Contractor and they can determine a set schedule. MSD will hold a second public meeting after a Contractor is selected to provide more specific details.

Residents may experience temporary reduced access to properties during active construction hours. The Contractor will notify residents prior to any access restrictions and will work to minimize these instances.


After all new sewer pipes are installed, the Contractor will restore the construction site according to all District and local requirements. This could include sodding any disturbed areas, replacing disturbed pavement, reinstalling fences, etc. More detail on this will become available after a Contractor is selected for the project ahead of construction in 2023.

What is the timeline?

This is the current tentative project schedule. This is subject to change based on a variety of factors including weather.

  • Project design completion: July 2021
  • Easement acquisition completion: Summer 2022
  • Estimated construction start: Summer 2023
  • 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

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.
