Water main rehab

October 11 2017

Various SR-Series equipment modules were used during different stages of a water main rehabilitation project in front off a professional crowd of engineers, contractors and municipalities.

Cleaning
The WJ180 Precision Jet Cutting module cleaned the 8” Cast Iron water main and removed tuberculation.

Pre-inspection/ tap cutting
CCTV “pre-lining” Inspection was done with the HA165 cutter module with front-placed camera. During this run, a protruding tap was removed and a cable pulled through on the way back to set the Spray Lining equipment.

Inspection
An inspection run between first and second layer of spray lining was completed and a cable pulled through on the way back.

Post-inspection/ lateral reinstatement
After the second layer of lining a post-inspection was conducted with the HA165 cutter module to reinstate a connection in the same run.
