Spring Avenue Sanitary Relief (12208)
As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is replacing approximately 2,600 feet of sewer in the City of Webster Groves. The Spring Avenue Sanitary Relief project will increase the size of the wastewater sewer which will reduce basement backups and prevent sewer overflows in this area. Construction is scheduled to begin in Spring of 2021 with anticipated completion in the Fall of 2022.
PROJECT UPDATE – Construction Near Yeatman and Newport Delayed Due to Utility Conflicts
August 31, 2021
As described at the May 12, 2021, public meeting, MSD’s contractor originally planned to begin construction at the northeast end of this project near Yeatman and Newport. However, the contractor encountered conflicts with the water mains in the area and needed Missouri American Water Company (MAWC) to relocate those mains before they could begin construction in this area.
To reduce overall delays to the construction schedule, the contractor began construction further down the project alignment and will complete the construction near Yeatman and Newport after MWAC relocates its water mains. While several factors could affect that schedule, at this time we anticipate work will take place around early November 2021. We also do not currently anticipate any changes to the estimated construction completion date of August 2022.

Project Map
What work is being done?
- MSD Project Clear is replacing approximately 2,580 feet of wastewater pipe.
- The pipe size will increase to 6 to 48-inches in diameter allowing a larger amount of wastewater to flow through the system.
- This project will eliminate one constructed overflow point where untreated wastewater can spill into local waterways.
Why is this project being constructed?
MSD is investing $1.1 million into this neighborhood with this project to alleviate basement backups and clean up our local waterways.
How will it be built?
MSD’s contractor, Wehmeyer Farms Inc., will install the pipe by digging through the surface, a process known as “open-cut.” The contractor will dig a trench several feet into the ground, remove the old sewer pipe, and replace it with a newer, larger pipe. They will work section-by-section, and will fill completed sections with gravel to reduce traffic disruptions.
How will this affect residents?
With any 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.
Because much of the construction takes place in the roadway, customers may experience lane restrictions or temporary road closures during working hours. MSD will have a traffic mitigation plan to ensure residents have access to homes and businesses.
Some residents may experience temporary access restrictions to their driveways. The contractor will give all property owners ample notification prior to access restrictions and will ensure access during non-working hours.
At least one MSD Inspector will be on-site part of the day for every day the contractor is working.
When will construction take place?
This is the current tentative project schedule. This is subject to change based on a variety of factors including weather.
- Construction start: May 2021
- Estimated construction completion: August 16, 2022
Previous milestones:
- First neighborhood public meeting: June 13, 2019
- Project design completed: July 19, 2019
What will it look like when it's done?
After the contractor installs all new pipes, they will restore the construction site according to all local and District requirements. The streets will be replaced from curb to curb with asphalt. Private property will be restored per the signed easement agreements. This could include sodding disturbed areas, replacing disturbed pavement, reinstalling fences, etc.
FAQs
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.
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 mdietiker@stlmsd.com or (314) 768-6380.
