Project Background
To minimize impacts to the roadway and adjacent residences and businesses, most of the sewer rehabilitation work will be performed using a trenchless method called Cured-In-Place-Pipe (CIPP). Construction will include improvements to sewer lower laterals within the project area. In some locations, street excavation may be required, and advance notice will be provided.
Project Benefits:
- Address aging sewer system infrastructure
- Increase reliability of our City’s critical sewer system infrastructure
