Robot ramps up demolition on work on Hope Valley tank upgrade

A demolition robot named Dorothy has joined the team helping SA Water complete the $21.6 million upgrade of its water storage tank in Hope Valley.

Dorothy is tackling the dangerous job of demolishing the 117 reinforced concrete columns that supported the tank’s old 125m x 175m roof.

With the electrically-powered robot’s support, SA Water has been able to eliminate manual handling risks for its contractors, and avoid the fuel emissions and potential spills associated with conventional diesel-driven machines.

General Manager of Asset Operations and Delivery, Mark Gobbie, said the project’s newest team member was well received by her colleagues.

“Ever since she was lowered into the Hope Valley tank by crane, our operators have enjoyed using remote controls to harness Dorothy’s brute force to quickly chew through the roof’s concrete pillars,” he said.

“We’re continually embracing smart technologies and seeking better ways to work, so having Dorothy on the team aligns with our approach.

Hope Valley water tank is SA Water’s largest storage tank and plays an important role in supplying water to more than 100,000 residents in Adelaide’s north-east.

“The tank – which is mostly underground – is bigger than a soccer pitch and holds 136 million litres of water – that’s 55 olympic swimming pools!” Mark said.

The tank is currently offline while the refurbishment work is underway and customers are receiving safe, clean water from another SA Water supply.

Work to remove and replace the tank’s roof and the columns started in May and is due to complete by the end of the year.

The project forms part of a wider, $89 million program to refurbish 111 water storage tanks across South Australia between 2016 and 2020.
