National Water Grid construction program

Working in partnership

The National Water Grid Authority (NWGA) is working in partnership with Australia’s states and territories to identify, plan and deliver a program of national water infrastructure investments that will improve the reliability and security of water for Australia’s regions and agriculture and primary industry sectors. 

The Australian Government has established the National Water Grid Fund as a $3.5 billion rolling 10 year water infrastructure program to fund water infrastructure investments.

As part of the 2021-22 Budget, the Australian Government has announced 12 new projects to continue developing the National Water Grid. A total of $75.7 million has been committed to new and augmented projects, with a further $22.3 million committed to eight business cases that will help inform future investment decision in water infrastructure for the ongoing development of the National Water Grid. In addition to this, the Australian Government has announced National Water Grid Connections funding pathway of up to $160 million over two years, will allow delivery of smaller scale water infrastructure projects. Under this funding pathway, there is up to $20 million available for each state and territory to deliver projects with an Australian Government contribution of up to $5 million per project.

The National Water Grid Fund is administered through the National Partnership arrangement. This National Partnership agreement contributes to Australia’s long-term economic growth and development by providing secure and affordable water through the construction of economically viable water infrastructure.

Under this arrangement, state and territory governments are responsible for developing project proposals.

Project proposals can be for business case development or construction funding.

National Water Grid priorities are guided by the National Water Grid Investment Framework and informed by the NWGA Science Program.

Water infrastructure projects contributing to the National Water Grid are also funded and administered through the Department of Infrastructure, Transport, Regional Development and Communications.

A series of printable documents have been developed to depict the progress of projects funded through the National Water Grid Fund (NWGF). An Investment Pipeline (PDF: 894 KB) is available to show the projects underway that underpin the Australian Government’s strategic long-term plan to secure Australia’s water future. A Map (PDF: 749 KB) is available to show the location of all construction commitments, including projects recently announced under the Connections funding pathway. A Summary of Construction Projects (PDF: 817 KB) is available to show the status of construction commitments, with a Progress Chart (PDF: 968 KB) that details key stages of planning and construction for each of these commitments also available.

Fast facts

Water storage is usually measured in megalitres (ML) or gigalitres (GL).

  • Did you know?

    One megalitre equals one million litres of water.

    One megalitre of water weighs about 1,000 tonnes.

    An Olympic-sized swimming pool holds 2.5 megalitres of water.

  • Did you know?

    One gigalitre equals 1,000 megalitres, or one billion litres of water.

    One gigalitre of water weighs about one million tonnes.

    Sydney Harbour holds more than 500 gigalitres of water.

An important part of our work with the states and territories is to investigate the feasibility of possible water infrastructure projects for the future to support prosperity and our national economy.
