Project

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.

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. 

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.
