The roof of the Advanced Water Recycling Plant building (WA) has recently been raised and installed, as part of the WA State Government’s $124.5 million Groundwater Replenishment Scheme.

WA Water Minister, Mia Davies, said two cranes were used to lift sections of the 3,500 square metre sheet metal roof, in a meticulously planned exercise that took two days to complete.

The Minister said the Water Corporation project – Australia’s first full scale Groundwater Replenishment Scheme – had now reached the halfway mark, with construction due to finish in mid-2016.

“The roof and steelwork were manufactured by AUSPAN, a family-owned operation based in Gnowangerup, and Bayswater-based Westforce were responsible for its installation,” she said.

“The total contract value for this part of the construction project was around $4 million. This is another great example of the Water Corporation’s support of regional and local businesses.”

The Minister said the Water Corporation supported the State Government’s Buy Local Policy where practical when purchasing goods and services.

“This project has contracted 20 WA-based suppliers so far, to the value of almost $20 million,” she said.

When complete, the plant will have the capacity to recharge 14 billion litres of recycled water per year into deep confined aquifers, providing an additional secure, rainfall independent water source for Perth.

“This project has the potential to supply up to 20 per cent of Perth’s future drinking water needs by 2060,” Ms Davies said.
