Where there's smoke ...

… there’s smoke testing of sewer lines underneath Highway 75. The work is part of the infrastructure project that closed six blocks of the main corridor north of Main Street in Luverne from Oct. 17 for a month. Smoke testing identifies sections of the sanitary sewer system that may have defects such as cracks, leaks or faulty connections that allow rainwater to enter the underground pipe network. The work also includes spot repairs, new manholes and directional boring of new service lines under the highway. The project is expected to be finished this week.
