Mini-System 35 Sewer Rehabilitation Project
The Mini-System #35 Sewer Rehabilitation Project is a sanitary sewer rehabilitation project focused on preventing groundwater infiltration into the sanitary sewer.
The goal of this Project is to make the sanitary sewer watertight. Princeton currently pays to treat more wastewater than residents and businesses actually produce. By reducing the amount of clean groundwater that enters the sanitary sewer system, Princeton will be able to reduce the costs associated with wastewater treatment. Additionally, the process used to seal the pipes will extend their useful life, forestalling more invasive infrastructure replacement projects and disturbances to private property.
Scope of Work
The Project involves repair work on both the public sewer pipes (mains) and the private sewer pipes serving each property (laterals) in the Project area. The Project primarily involves injecting a non-toxic chemical grout into the joints and cracks of sanitary sewer pipes, to eliminate groundwater leaking into the sanitary sewer system. Chemical grouting is a trenchless technology which does not require any digging.
Right of Entry Agreements
In order to complete the Project, Princeton will need temporary access to the portions of the public sanitary sewer system located on private property. Right of Entry Agreements were mailed to affected residents on February 11, 2022.
