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 Infrastructure Development Fund as a rolling 10 year water infrastructure program to fund water infrastructure investments. An additional $2 billion in capital funding was announced as part of the 2020/21 Federal Budget, bringing the Australian Government’s total funding commitment under the National Water Infrastructure Development Fund to $3.5 billion. This program is administered through the National Partnership for the National Water Infrastructure Development Fund—Capital Component.

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 include feasibility projects, business cases and infrastructure development proposals.

National Water Grid priorities are guided by the National Water Infrastructure Investment Policy 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.

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.
