The Tank Inspectors

With an ROV, tanks do not need to be drained or taken out of service, minimizing water loss and saving resources is very important.

Jo Hulands, Owner, The Tank Inspectors

Ron Perrin Water Technologies

We use the vehicle instead of divers for tank cleaning. Before we got the vehicle we would have to drain the tanks and the utility would lose up to 100,000 of gallons of water.

This is amazing! Instead of draining tanks, we inspect and vacuum out the sediment with the DT640Vac Utility Crawler.
