The building is not connected to mains water or sewerage. Water saving toilets used at the venue use bacteria to efficiently break down waste products, reducing the need for water by up to 80%. Toilets include urinals that use no water for flushing and special hybrid toilets that use no, or only minimal, water. Conventional dual flush toilets in the building use bore water, thereby saving precious rainwater for drinking and other potable use.

Biological waste treatment tanks in the Water Treatment Room house the bacteria used to break down toilet wastes. Waste slowly passes through the tanks and is broken down to produce gas (vented) and water (of very high quality, used for irrigation). These tanks should never need to be emptied.

A 60 000L rainwater tank (RIGHT) collects rainwater from the roof surface for use in the building.  An on-demand solar pump then delivers water to two header tanks on top of Technology Tower. These header tanks provide the water pressure (gravity) back into the building.  Drinking water is treated via filtration and ultra-violet sterilisation before being used.

An Ecomax system treats all traditional toilet, basin and sink waste waters to such a high standard, that it is acceptable to return the treated liquid into the ground water table.
