Water for future generations

Water for future generations

We take our role as custodians of future water security and resources seriously. We protect and improve the environment and our water assets for future generations.

Like many South Australians, we've become very good at managing water. With growing environmental challenges, expanding knowledge and technology and changing expectations in terms of water usage, we continue to develop new ways to care for the community and the environment.

And our role extends to sponsorships and education programs reaching more than 10,000 school children each year. The generation of the future is learning about water management, conservation and environmental protection early.

How we plan

Our water security planning analyses water availability and historic customer demand in order to project future water supply requirements. We consider residential and non-residential use and match the demand to the potential influence of:

  • climate, including the latest climate change data (rainfall, temperature and evaporation)
  • population projections
  • state Gross Domestic Product (GDP)
  • water prices, water restrictions and network changes

Our water security plans - which are developed for each region in South Australia - are one way of driving our need to secure water for future generations. These plans form part of our regulatory business proposal – Our Plan 2020-24 - which we develop and submit to our economic regulator, the Essential Services Commission of South Australia (ESCOSA) every four years.

Kangaroo Island

Our Kangaroo Island long-term Water Security Plan ensures a secure water supply to meet the island’s residential and commercial needs into the future. To enable growth on the island, we are working towards a new desalination plant at Penneshaw and increasing water storage.

The needs of the Kangaroo Island community are reviewed yearly and recognise their changing environment.

South East

We have a Water Security Plan for the state's South East and Murray Mallee that covers 19 towns in those regions to make sure they have a reliable source of water into the future. Available water resources have been analysed for:

  • Water allocations. We hold groundwater allocations across the South East and Murray Mallee. Based on current local groundwater trends, the allocations are projected to provide sufficient water supplies for these two regions for the foreseeable future.
  • Maintaining water quality. We strive to deliver the best quality water to all our customers through constant monitoring and testing programs.
  • Infrastructure upgrades. The Blue Lake is and will remain Mount Gambier's primary water supply source. We want to maintain a sustainable level of extraction from the lake and to do this, we are looking to diversify the water sources that supply this regional city. While there is generally adequate pumping infrastructure to support water supply needs, the plan recommends some infrastructure upgrades.

Eyre Peninsula

The focus of water security and supply on the Eyre Peninsula revolves around the developing of a new seawater desalination plant at Sleaford Bay, near Port Lincoln.

The majority of water on the Eyre Peninsula is sourced from groundwater, but in future this will be supplemented with seawater desalination. This will secure supply which is more climate-independent, and give the Uley South Basin time to recharge.

Work in developing this new plant has begun, in partnership with the Eyre Peninsula community and Traditional Owners.
