Water Conservation

At the Australian Arid Lands Botanic Garden

Water Fact:
The Visitor Reception building collects rainwater in a large underground tank for use in the kitchen, cafe and toilets to save reticulated mains water. Treated waste water from the building is used for irrigation in sections of the garden.

Water Fact:
In the Garden, water is used wisely in water efficient drip irrigation and conserved by use of mulches and by growing hardy and drought tolerant plants.
