  • Securing the Great Southern’s public, industrial and agricultural water future
  • Demand for water expected to rise by 75% to 2043

More wastewater recycling, increased stormwater harvesting and sustainable groundwater are three main planks of a strategy designed to meet the public, industrial and agricultural water needs of the Great Southern over the next 30 years.

Water Minister Mia Davies said the Department of Water’s Great Southern regional water supply strategy launched today provided a blueprint to meet a forecast water use increase of 75 %, or more than 20 Billion litres a year, by 2043.

 

 

 

“The demand will be driven by population growth in Albany, Denmark and Katanning, new iron ore and gold mining developments, and expansion of industry and irrigated agriculture.” Ms. Davies said.

“By 2050, it is predicted that rainfall in coastal areas will be 2 to 6% less and up to 15 % less in inland areas.”

“The Department of Water developed the strategy to ensure co-ordination and timely planning of sustainable water supplies that support long-term regional development.” Ms. Davies said.

“The Water Corporation and Department of Water have secured the medium-term town water supplies for Albany and Mount Barker, and Royalties for Regions-funded work in the Albany hinterland is identifying potential groundwater for industry, agriculture and future expanded scheme options.”

The Minister said the Great Southern region was well placed to achieve water security through innovation.

“The region has the highest level of wastewater recycling in the State, and this will increase with $1.65 Million in Royalties for Regions-funded wastewater harvesting and water reuse projects in the shires of Broomehill-Tambellup, Cranbrook, Kojonup and Plantagenet.” Ms. Davies said.

“We will continue to foster partnerships with local government which have used State funds to help build community water supplies for sports ovals and parks, which in places like Woodanilling have reduced scheme water use by more than 50 %.”

“Innovation is supported by local planning policies in Jerramungup, Plantagenet and Denmark encouraging rainwater tanks, greywater recycling and water-efficient appliances for new residential developments.”

Under the strategy, desalination of seawater also provides source options beyond 2030.

  • The strategy area covers about 39,000 square kilometres
  • It extends along the WA coastline from Walpole to the eastern border of the Shire of Jerramungup, and north to the shires of Woodanilling and Kent
