Crawler technology boosts safety for water tanks
Ultrasonic remote-controlled technology has been used by Water Corporation for the first time to inspect a drinking water tank in Karratha.
The device, known as a crawler, was recently used on the 25 million-litre water tank north-east of the Leisureplex.
Water Corporation North West regional manager Rino Trolio said the crawler made it safer for employees to check water tanks.
“The remote-control crawler attaches to the external tank wall using magnets, allowing it to roam up to 30 metres high,” he said.
“It measures the thickness and condition of the steel using ultrasound technology, which allows us to capture a clear picture of the condition of the tank.
“Previously, our employees used cherry pickers to physically inspect the tanks. By using the crawler, we have eliminated any risk to our employees through working at heights.”
The crawler can also be used to inspect confined spaces less than 60cm wide which are too small for employees to enter. Mr Trolio said Water Corporation planned to roll out the technology Statewide.
