The WA State Government will invest $1.7 million in Water Corporation upgrades to Wiluna’s water treatment plant. WA Water Minister, Mia Davies, said the upgrade would improve water quality in Wiluna and cater for future growth.

“The Water Corporation’s upgrade will enable the water treatment plant to process around 265,000 litres of water each day, which will cater for growth and ensure water supply needs can be met during peak demand periods,” Ms Davies said.

“The increased treatment capacity will allow all three of the 47,000 litre tanks at the plant to be used, increasing the town’s water storage capacity.”

The Water Corporation will also install a new Electro Dialysis Reversal (EDR) plant to reduce high nitrate levels that naturally occur in the groundwater used to supply Wiluna.

“The upgrade will mean the Water Corporation will no longer need to supply bottled water for nursing mothers and bottle-fed infants, which is currently the case,” the Minister said.

The specialised EDR plant would be constructed and assembled in Perth and then transported to Wiluna.

“Once it has completed its almost 1,000 kilometre road trip, the Water Corporation will install it at the existing plant in Wiluna,” Ms Davies said.

Work will start at the end of July 2015 and take around four months to complete.
