Crawler tech­nol­ogy boosts safety for wa­ter tanks

Pilbara News - - News - Tom Zaun­mayr

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.
