Hathaway Drive Sanitary Relief (13432)
About the Project
Public Meeting - January 30, 2023
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.
- Construction is estimated to begin in February 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?
Type of Construction:
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.
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.
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.
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: February 2023
- Estimated project duration: 6-9 months
Previous Public Meeting - Design Phase
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.
