Slip Lining the Lake Macatawa Water Transmission Main

Slip lining is a method for extending the life of underground infrastructure by inserting a new, smaller-diameter pipe inside an existing pipe. The new pipe creates a smooth, corrosion-resistant inner lining, which protects against potential damage or leaks from the older line.

Holland BPW pulled a pipe that is ¾ mile long through the water transmission main that runs beneath Lake Macatawa, delivering fresh water to the service area. It took two full days to get the pipe all the way across the lake. Afterwards, the entire length was grouted with a special material to hold the new pipe in place.
