Tank built on site at Westech

For the first time ever, a rainwater tank was built onsite at Westech.

AN innovation at this year’s Westech Field Days event may revolutionise the industry and could prove vital for future drought resilience.  

A machine was brought to the event which can build rainwater tanks on site.  

Toowoomba-based rainwater tank engineer, inventor, and Australian Poly Tanks business owner Michael Theuerkuaf said his invention was wholly his own, and according to general industry knowledge this may be the first time it has been done in the world — at least with rainwater tanks this size.  

Mr Theuerkauf said he took a large fixer machine [what he calls an oven] in a factory and shrunk it down to fit within the regulations for transport.  

The machine is towed behind his truck which carries the materials that go into the fixer machine to eventually build the tanks.  

At Westech the machine turned out a new rainwater tank every three hours, but Mr Theuerkauf said with the parts at home, he could turn out one every one-and-a-half hours.  

Only with enough materials for three or four tanks, Mr Theuerkauf said his intentions at Westech was only to show off the machine, not necessarily to build a sale yard. 

“We could probably go up another extra axel [meaning considerably more tanks],” he said.  

Depending on whether his company chooses to build a depot, Mr  Theuerkauf said they could compete for speed and efficiency with the biggest tank companies. 

“We just have a semi-trailer and a machine at this point,” he said.  

Mr Theuerkauf has been building machines for 20 years and has been working on this concept for a while.  
“Then Westech come along, and I thought ‘this is ideal for us’,” he said.  

“The concept behind it is, to save on the fright cost of transporting to rural remote areas of Australia.  

“[For a rainwater tank like the ones on site], you’re transporting large volumes of air.” 

Mr Theuerkauf said the innovation was design with regional areas in mind.  

“This is exciting,” he said.  

“We want to get the idea out to local interests.”
