A sewer main that serves Malmstrom Air Force Base and collects sewage from a large portion of the east end of town has been deteriorating.

During their Feb. 6 meeting, City Commissioners will consider a $1.437 million contract to Planned and Engineered Construction to reline a deteriorated portion of the main between 15th Street and 38th Streets North using trenchless technology.

This project consists of lining about 10,176 lineal feet of 18-inch, 24-inch and 30-inch sewer main with Cured-in-Place-Pipe (CIPP); and internally reinstating approximately 18 service connections. The project is scheduled for substantial completion in 130 calendar days, according to the staff report.

Funding for the project has been budgets through the city’s Sewer Fund.

The construction may require a three to four day detour or other traffic control on 15th Street North between River Drive and 10th Avenue North. The project may also require the temporary closure of the sidewalks along 12th Avenue North but access to residences and businesses adjacent to construction zones will be maintained, according to the staff report.

Specifications for the project were advertised twice in the local paper and three bids were received in January. One of those bids was a letter declining the project due to the company’s backlog of projects. The Planned and Engineered Construction bid was $1,437,010 and the other was $2,359,445.70.
