Science Program

The National Water Grid Authority (NWGA) Science Program informs funding decisions to make sure we are investing in projects that will provide clean, reliable and sustainable water resources. Our targeted science program brings together advice from Australia’s leading science organisations to identify how we can best deliver long term benefits for our communities.

Goals, themes of work and arrangements for guiding investments under the program are outlined in our Science Strategy. The three themes within this strategy include:

  • water resource assessments
  • alternative and emerging options
  • new information resources and communicating science.

The NWGA Investment Framework sets out how we use science to identify water infrastructure priorities across Australia.

Priorities informed by science

The current priorities for the NWGA Science Program include:

  • identifying water-related projects ready for further planning and development, for example, multi-disciplinary water resource assessments
  • analysis of water infrastructure proposals and other water transfer, storage and harvesting options
  • examining the opportunities around alternative technologies that support reliable water supplies for agriculture such as Managed Aquifer Recharge (MAR), desalination of brackish groundwater supplies and water recycling.

There are many science projects currently underway across Australia and several have been completed. This includes three rapid desktop appraisals by CSIRO. These analysed opportunities for new groundwater-based infrastructure; low-cost desalination; and managed aquifer recharge.

The Australian Government commissioned the CSIRO to undertake a detailed technical and economic analysis to comprehensively assess both the Bradfield Scheme including modern variants. The research assessed the feasibility of long distance movement of water from north Queensland to support agricultural development further west and south.

In consultation with state and territory governments, the Science Program is also funding further water resource assessments across the north – including the Roper River, Victoria River and Southern Gulf catchments – building on the learnings from the 2018 Northern Australia Water Resource Assessment (NAWRA) project.

We also engaged Flinders University’s National Centre for Groundwater Research and Training to look at salinity risk from groundwater extraction in the Northern Territory. The results of this salinity risk study will help inform water planning and licensing decisions.

Who we work with

We work closely with state and territory governments and leading national science institutions, including:

  • Geoscience Australia
  • the Bureau of Meteorology.

Through these successful partnerships, we are continuing to deliver best-practice scientific research that informs the planning and investment of the next generation of water infrastructure for Australia.
