Price to Pioneer Sanitary Relief (12368)
Why is this project being designed?
Our team of Engineers have determined that the existing wastewater sewer in this neighborhood has issues dealing with higher flows of water which lead to instances of the sewer surcharging.
In addition, there is a known overflow point within this area where untreated wastewater is discharged into waterways during heavy rainfall. That overflow point must be removed in order to clean up our local waterways.
What is the goal of this project?
MSD Project Clear is investing approximately $5.2 million to design this project to increase the size and depth of the existing sewer. This will alleviate existing problems resulting from undersized sewers.
- Construction is estimated to begin Summer 2022.
- MSD Project Clear will replace approximately 5,460 feet of wasterwater pipe.
- The pipe size will increase to between 8 to 30-inches in diameter allowing a larger amount of wastewater to flow through the system.
- This project will remove 1 known overflow point to prevent untreated wastewater from spilling into local waterways.
What can residents expect?
Though construction for this project is not estimated to begin until Summer 2022, it is important to be prepared for what to expect. By the Fall of 2021, residents whose property will need to be accessed to construct the project will be contacted in order to obtain necessary easements.
Type of Construction:
With any type of construction, residents can expect to see and hear heavy equipment during the sewer excavation process. The majority of this project will be constructed by digging through the surface of the ground, in a process known as “open-cut” construction. The pictures above depict what a neighborhood will look like before, during, and after a typical open-cut project.
To minimize traffic impacts, “tunneling” will be used to cross Dielman Road. This means that a hole called a boring pit will be dug at multiple locations to drop a Tunnel Boring Machine underground to dig through the soil and rock. Tunneling is being used in this area to ensure that the surface of Dielman Road is disturbed as little as possible. Tunneling will also be utilized to cross the various railroads in the area to minimize track disturbance.
As a part of this project, MSD Project Clear does expect traffic impacts to residential streets in this area. More specific information including timing and locations of these closures will become available once the project has a Contractor and they can determine a set schedule.
MSD Project Clear also expects that there will be instances where property owners could have reduced or limited access to their properties due to this project. However, the Contractor will be required to maintain access to both residential and commercial properties. The Contractor will provide notice to affected residents before construction takes place.
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. More detail on this will become available after a Contractor is selected for the project ahead of construction in the Summer of 2022.
What is the timeline?
This is the current tentative project schedule. This is subject to change based on a variety of factors including weather.
- Project design completion: Fall 2020
- Easement acquisition completion: Fall 2021
- Estimated construction start: Summer 2022
- Estimated project duration: Two years, Summer 2024
No, the Contractor will maintain utility service at all times.
In accordance with MSD policy, the Contractor will restore all disturbed surfaces to previous or better conditions.
The Contractor will be committed to minimizing any instances of access issues to residential or commercial property. However, it is expected that there will be times of reduced or limited access on both residential and commercial properties as a part of this project. Once selected, the Contractor will provide notice to affected residents before access is restricted.
