Projects

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is designing a project in the City of Brentwood to separate a combined sewer into two separate sewers, one for stormwater and one for wastewater. This project is estimated to begin construction in the summer of 2026.

What is the goal of this project?

MSD Project Clear is investing approximately $30 million to separate the sewers in the City of Brentwood and increase the size of the wastewater and stormwater pipes. This will reduce the likelihood of basement backups in homes and businesses and will allow MSD to remove one constructed overflow point (known as a CSO) from its wastewater sewer system.

Project Facts

Construction is estimated to begin in the summer of 2026.

MSD Project Clear will construct approximately 9,850 feet of wastewater pipe and 3,750 feet of stormwater pipe.

The pipe size will increase to between 8 and 36 inches in diameter, allowing a larger amount of water to flow through the system.

 

What can residents expect?

Though construction for this project is not estimated to begin until the summer of 2026, it is important to be prepared for what to expect. While much of the construction will take place in existing easements, MSD may need to obtain new easements from some property owners. Prior to construction, residents whose property will need to be accessed to construct the project will be contacted to obtain the necessary easements or to be notified of work that will take place in existing easements.

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: Late Summer 2023
• Easement acquisition completion: Late Summer 2025
• Estimated construction start: Late Summer 2026
• Estimated project duration: 3.5 years
