2025 Sewer Lining Project

The sewer cleaning project in Lebanon, NH aims to improve the city's sewer system by clearing out blockages and debris, reducing the risk of sewage backups and overflows. The project involves the use of specialized equipment and techniques to clean and maintain the city's sewer lines, including highpressure water jets and vacuum trucks. The project is expected to enhance the efficiency and reliability of the sewer system and ensure the proper disposal of wastewater.

This project involves the rehabilitation of existing sanitary sewer infrastructure across six separate locations. The scope includes cured-in-place pipe (CIPP) lining of approximately 4,345 linear feet of sewer mains, broken down as follows:

• 2,600 linear feet of 12-inch diameter pipe

• 1,450 linear feet of 8-inch diameter pipe

• 295 linear feet of 10-inch diameter pipe

In addition to the sewer main lining, the project includes the epoxy coating of five (5) sanitary sewer manholes at a single location to extend the service life of the structures.

A portion of this project is located within an active construction site that is expected to reach substantial completion by the end of November 2025. Work in this area—including the lining from SM-8 to SM-13 and the epoxy coating of manholes—will need to be scheduled between December 2025 and June 1, 2026.
