|Abstract: ||Water is precious, particularly in South Australia, the driest State in Australia,
with over 80% of its land area receiving less than 250mm of rainfall per year.
Security of water supply has always played a critical role in the economic and
social development of South Australia, and will continue to do so while
dependency on water from the River Murray is so high and there is competition
over this from states and for different uses – municipal, irrigation, industry, and
the environment. The drive towards sustainable development has evolved to
attenuate overconsumption of the world’s natural resources of which water is a
Provision of reliable water supplies to regional South Australia has always
presented challenges, given the vast distances involved and the limited number of
natural water sources. Despite these, a majority of South Australians enjoy the
benefit of a reliable and safe water supply, adequate waste disposal system, good
community health and high standard of living. A challenge remains to determine
the sustainability of current major water pipe transfer systems from remote
resources to small communities. There may be scope for managing existing water
supplies more effectively and further developing local water harvesting and reuse
solutions to minimise the need for more significant infrastructure investment.
This study investigates the challenges and opportunities for extending
development of non-potable (secondary) water supply schemes in South
Australian towns. These schemes will conserve the State’s freshwater resources.
The primary focus of this study is harnessing stormwater runoff and treated
effluent generated by normal township development to supplement higher quality
public water for uses such as irrigation of public areas and sporting fields in
country areas. Water harvesting and reuse is not likely to occur due to some
technological breakthrough but through application of known technology and the
adoption of water conscious ethics by society. However, it is a sensible reality for
the South Australian climate, particularly when coupled with appropriate
conservation and suitable landscaping practices. Thus, the major theme of this
study is information sharing since if people are familiar with and understand the
concepts then more communities may be encouraged to develop their resources.
Water reuse has proven to be a beneficial strategy for addressing stormwater
runoff and wastewater disposal problems and alleviating localised water supply
problems for several South Australian towns and communities. The existing
projects demonstrate both the strong community-based and innovative approach to
water resources management in this state. They are inherently simple in form, and
can often be assembled with readily available materials by people with a basic
understanding of plumbing and construction skills (locally available). The
potential for localised water harvesting and reuse in South Australian towns is
generally limited to single purpose communal non-potable systems. Further, it is
likely to only be sustainable in rural communities willing to make a commitment
to its long term, proper operation and maintenance, or they could endanger public
