After posting the “What the Heck is Pipe Pigging?” article by Matt Timberlake on, we received this cool video from NEW Water (the new identity for the Green Bay [Wis.] Metropolitan Sewerage District) that highlights the story of a pipe plug traveling through a force main.   

NEW Water had a problem. A slimy one. The “Interplant Force Main” between the sewerage district’s De Pere and Green Bay facilities was getting clogged. After testing, data collection, and a final analysis, NEW Water staff members employed an innovative idea: a non-chemical, environmentally friendly one that saved $378,000 — The Poly Pig. 

Field Services Technicians Bob Zepnick and Kim Williams take viewers on the journey of the plug migrating 7.1 miles in four hours. 

The cylindrical, polyurethane, $65 plug traveled like a squeegee on a windshield, scraping away slime and clearing the path for wastewater to journey to Quincy Street to be cleaned and returned to the waters of Green Bay.
