Water Corporation recently used remote controlled ultrasonic technology, known as a ‘crawler’, to inspect one of Karratha’s drinking water tanks.


This is the first time the technology has been used by Water Corporation and provides a safer way for employees to check tanks.


Water Corporation North West Regional Manager, Rino Trolio, said the crawler was used in June to inspect the 25 million litre steel water tank north east of the Karratha Leisureplex.     


“The remote control crawler attaches to the external tank wall using magnets, allowing it to roam up to 30 metres high,” Mr Trolio 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. This information is then used to determine if the tank requires any maintenance.


“Most importantly, this is a safer way to inspect our tanks. 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 60 centimetres wide which are too small for employees to enter.


Mr Trolio said Water Corporation planned to roll out the crawler technology across the State.


“This is a great example of our employees taking the initiative to use technology to work smarter and safely,” Mr Trolio said.
