South East

South East

Our Water Security Plan for the state's South East and Murray Mallee was finalised in late 2015. Demand models have been developed for each of the independent SA Water town supplies in the regions. Available water resources have also been analysed for:

  • allocation
  • maintaining water quality
  • ensuring our infrastructure is suitable to extract the required volumes.

This plan focuses on 19 towns within the South East and Murray Mallee. These towns are supplied water from individual groundwater sources e.g. bores or the Blue Lake. Towns which receive water from the River Murray will be the subject of a separate water security plan. This will be delivered at a later date.

Water allocations

SA Water holds 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.

Water quality

SA Water strives to deliver the best quality water to our customers. To achieve this, we follow a stringent regime of water quality testing and investigations. Work is underway to connect new bores in Kingston SE and Robe to further improve local water quality. 

SA Water is also working with the Department of Environment, Water and Natural Resources (DEWNR) to investigate Bordertown's groundwater supply options. This will help inform management of the aquifer to ensure its long term sustainability.

Infrastructure upgrades

There is generally adequate pumping infrastructure to support our supplies. The plan does recommend some 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. To do this, we are looking to diversify the water sources that supply the regional city. This includes investigations into a new bore field to help supply the city.

SA Water has also been undertaking work to improve Naracoorte's water supply. This includes alterations to the distribution system and investigations into alternative water sources.
