Rainwater Re-use is the technique of collection and storage of rainwater in tanks or natural reservoirs directly from rainwater runoff – be it rooftop capture, surface runoff, infiltration capture – and the proceeding filtration and pumping of this water into applications of non-potable water.
Collecting Rainwater for re-use has become a common step in the construction of every water system for homes, commercial buildings, industrial sites and about every other urban aspect of society. The Re-use of rainwater provides an alternate source to mains water, allowing less use of our precious water resources and reducing the load on our environment.
According to the Australia Bureau of Statistics, one in four households utilise the benefits of Rainwater harvesting systems along with the statistic that 177 Billion litres (9% of residential water usage) comes from rainwater and is the 3rd largest source of water in Australia – after surface and groundwater. It is obvious that Rainwater harvesting has become and vital part of Australia’s Water usage and will only continue to grow.
