Water is a precious resource in Australia. Storing rainwater in dams and pumping it around the country is energy-intensive. So local storage is a huge advantage.
We have about 60,000 litres total capacity, stored in two large underground tanks. We pump from their to flush toilets and irrigate the gardens
In the course of a year we empty and refill those tanks three or four times, so we’re actually getting 200,000 to 240,000 litres of water from our 60,000 litre storage.
As this mini-video explains, there are broader ecological impacts of urban development that make local and domestic water storage a priority.
