Inspection of the water main between Crépieux water treatment plant and Bruyères tank

Grand Lyon, France – 2016

Within the framework of structural and operational assessment of the Grand Lyon’s water supply network, Subsea Tech carried out the inspection of two DN800 water mains located between the Crépieux water treatment plant and the Bruyère tank. Thanks to the automatic pipe profiling system embedded on a mini-ROV, 3D profiles of the pipes were performed over 100m length. Thickness measurement were also realized with a Cygnus US gauge mounted on the ROV.

Objectives 

  • Visual inspection, profiling and thickness measurement of the water mains between the Crépieux water treatment plant and the Bruyères tank.
