Last week, we told you how employees with the City’s Wastewater Division joined together to blast apart a root ball that was blocking 90% of a sewer pipe.
Here is a video of the operation, narrated by Nevin VanFossan, the operator of the CCTV van. The Jet/Vac Truck operator came to the root from one end of the pipe while VanFossan used a camera from the opposite side of the pipe to guide the Jet/Vac operator to the root obstruction.
