Robots help with drain repairs

By Melissa Chung

City of Melbourne has spent $1.35 million improving the CBD’s drains and water storage using robots.

The tiny robots are capable of relining almost a kilometre of drains in three to four days. Pipe replacement would normally take four to six weeks.

“We can much more effectively send down these manually operated robots to carry out all the inspection and repair works,” Lord Mayor Robert Doyle said.

The drain robot is equipped with CCTV cameras. It maneuvers a 5-8mm thick fibreglass liner into the concrete pipes, which reacts with UV to create a hard lining.

“Rather than having to close off busy roads and junctions for several weeks and create huge holes to access the drains, we can much more effectively send down these manually operated robots to carry out all the inspection and repair works,” Cr Doyle said.
