Grand Glaize Trunk Sanitary Relief (12272)

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is designing a project to replace approximately 1,726 feet of wastewater pipe in City of Ballwin. The project is estimated to begin construction as early as the Spring of 2022.

Public Meeting - August 26, 2020

Project Map

Why is this project being designed?

As part of their evaluation, our team of engineers determined that the sewer in this neighborhood is undersized and in need of repairs. During intense rainfall, the sewers become overloaded leading to basement backups.

What is the goal of this project?

MSD Project Clear is investing approximately $722,000 to design and construct this project to increase the size of the existing sewer to reduce the likelihood of basement backups during heavy rainfall.

Project Facts

  • Construction is estimated to begin as early as Spring 2022
  • MSD Project Clear will replace approximately 1,726 feet of wastewater pipe
  • The pipe size will increase to between 6 and 15-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 at least Spring of 2022, it is important to be prepared for what to expect. In the Spring of 2021, residents whose property will need to be accessed to construct the project will be contacted in order to obtain necessary easements.

At this time, MSD Project Clear anticipates this project will be constructed by digging through the surface of the ground in a process known as “open-cut” construction. The majority of construction work will take place in backyards and areas adjacent to the road.

Traffic and Access: MSD Project Clear anticipates minimal traffic and access disruption, however, temporary lane closures may be required. 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 Geremma Dr. The contractor will notify property owners in advance of any access restrictions.

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.

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.

What is the timeline?

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

  • Complete Project Design: Fall 2020
  • Easement acquisition completion: Fall 2021
  • Estimated construction start: Early as Spring 2022
  • Estimated project duration: 1 year or less
