We live on a dry continent and we recognise that Australians and our producers have a very important relationship with water.

Having already achieved our target to reduce potable water intensity by 15 per cent from our baseline year, FY13, the past 12 months have seen us make some good progress on non-potable water.

Optimising our systems

In recent years, we have found that when we install a non-potable water system, the commissioning and optimisation are the greatest challenges. While it’s hard to optimise a system, this step provides the greatest value; so this year, we focused on improving some existing systems we already had in place.

We made some major adjustments to the water capture system at 23 Furzer Street in Woden ACT, which saw the water rating improve back to a 5.5 Star NABERS rating, and we have re-commissioned systems in several of our retail assets.

At 275 Kent Street in Sydney, we also optimised the existing rainwater tank to make the most of its large capacity. By starting to feed captured condensate water into the tank, we have made a huge impact and expect the water harvest to be at least double the previous year’s amount.

At Ascot Green in Brisbane, we have installed a new 50,000 litre water tank that is being used for dust suppression and stormwater treatment.
