Water Proofing the South. A localised,
integrated water management strategy
for Adelaide’s southern suburbs.
With population growth, industrial demand and the
predictions for climate change, the provision of ‘fit-forpurpose’ alternative water sources such as reclaimed water
and stormwater is critical. Water Proofing the South will
ensure water use in the City of Onkaparinga is economically,
environmentally and socially sustainable.
The $185 million Stage 1 of Water Proofing the South will
deliver 3.8 gigalitres of treated effluent and stormwater for
reuse in new housing developments, the irrigation of public
open space and the local viticulture industry.*
The $30 million Stage 2 of Water Proofing the South will
harvest 2.8 gigalitres of stormwater, making 2.2 gigalitres
available for reuse through distribution systems. These systems
connect wetlands and managed aquifer recharge schemes
with local reserves, open space, schools and sports fields.**
* Stage 1 is made possible by the collective effort of the City of Onkaparinga,
SA Water and the privately owned Willunga Basin Water Company with
significant funding support from the federal and state governments.
** Stage 2 is to be delivered by the City of Onkaparinga, but is made possible
with funding support from the federal and state governments.
