Lindley Drive Sanitary Relief (12329)

Lindley Drive Phase 1 (12329)

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is replacing approximately 6,200 feet of sewer in the City of Olivette. The Lindley Drive Sanitary Relief project will increase the size of the wastewater sewer which will reduce basement backups and prevent sewer overflows in this area.

Construction began in October of 2020 and was completed in Fall of 2022.

Public Meeting - September 24, 2020

About the Project

Project Map

What work is being done?

  • MSD Project Clear is replacing approximately 6,242 feet of wastewater pipe.
  • The pipe size will increase to 8 to 21-inches in diameter allowing a larger amount of wastewater to flow through the system.
  • This project will eliminate four constructed overflow points where untreated wastewater can spill into local waterways.
  • This project will remove one pump station and enable the sewer to flow using gravity rather than a pressurized pipe. This will result in more reliable sewer service for customers in this area.

Why is this project being constructed?

MSD is investing $3.65 million into this neighborhood with this project to alleviate basement backups and clean up our local waterways.

How will it be built?

The majority of this project will take place on private properties. The construction corridor will go through back yards of properties on Stoneleigh Towers, Bon Hills Drive, Hill N Dale Lane, Green Oaks Drive, and Bonhomme Woods Drive. MSD’s contractor will install the pipe by digging through the surface, in a process known as “open-cut”.

To reduce traffic disruptions on other streets, the contractor will tunnel under N. Price Road and Dielman Road.

How will this affect residents?

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

While most of the construction will take place on private properties, residents may experience some disruption to traffic during construction on Bon Price Lane. One lane of traffic will remain open at all times.

When will construction take place?

Construction timeline:

  • Construction start: October 2020
  • Construction completion:Fall 2022

Previous milestones:

  • Second neighborhood public meeting: September 24, 2020
  • Project design completed: April 2020
  • Easement acquisition completed: March 2020
  • First neighborhood public meeting: November 7, 2018
  • Bon Hills Subdivision meeting: April 26, 2018

What will it look like when it's done?

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.


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.

As most of the construction will take place in backyards, MSD Project Clear does not anticipate those properties will have access issues during the construction of this project. 

MSD Project Clear will be doing work through Bon Price Ln., and during active construction, some property owners on this street 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 or place steel plates over trenches during non-working hours so property owners can use their driveways during those times.

Trees may need to be removed to construct parts of this project. If there are good options to avoid removing trees, MSD will make every attempt to do that. Property owners with trees that will need to be removed that are not located in already existing easements will have been compensated for the removal through the easement acquisition process. If you have questions about specific trees, please contact Mark Dietiker at or (314) 768-6380.

MSD does not anticipate this project will affect sewer service or other utility services, nor do we anticipate significant property access restrictions. As such, residents should still be able to work from home. If you have a specific concern about this project affecting your working situation, please contact Mark Dietiker at or (314) 768-6380.
