Boone County · 2025
Project summary
An interstate widening in Columbia, Boone County, put existing sanitary and water lines in the way. Working for the highway contractor, Kuesel hydro-excavated the existing utilities, then relocated 745 LF of 8" PVC sanitary sewer with four new manholes, rebuilt an existing 8" drop, installed 265 LF of 16" steel casing, and grout-filled the abandoned sewer.
A second crew relocated about 400 LF of 6" and 12" C900 water main with gate valves, an 18" steel casing and a live tie-in.

Challenge → approach
Relocations beside a highway job mean live lines and another contractor's schedule. Kuesel located the existing utilities by hydro excavation before digging, ran sanitary and water with separate crews, and made the water tie-in live.
