Australia’s urban water infrastructure is critical for the liveability and prosperity of more than 20 million people and 9 million connected properties in our towns and  cities. It also serves industries, supporting growth in productivity and employment across the country.

The role of water in the public realm is also diverse. For instance, as well as drinking water, water plays an important role supporting urban cooling and amenity.

The 2019 Australian Infrastructure Audit found that the ‘urban water sector faces challenges, including the impacts of climate change, population growth, ageing assets, and changing needs and expectations from users. Failure to adequately address these challenges could lead to rising water bills, as well as exposing users to risks of declining service quality and reliability.

Without appropriately planning for these challenges, there could be severe urban water shortages or restrictions in many  parts of the country.

For regional towns, water utilities often rely on a single supply source, with no physical link to an alternative bulk water supply. The lack of supply diversification creates further water security risks for  these communities.


The proposal is for a mix of infrastructure and non-infrastructure responses, such as demand management, to efficiently meet agreed service standards for water security in Australia’s towns and cities. Infrastructure interventions for towns and cities could involve new water sources, such as recycling and desalination.

Long-term urban water planning will need to be supported by stronger institutional arrangements, as recognised in the Early-Stage Proposal for Bulk water supply security, which is separately included on the Infrastructure Priority List.

Collaboration and knowledge sharing will also be important to achieve the best outcomes, taking into account the roles  and responsibilities of state, territory and local governments.
Appendix B provides a list of submissions received by Infrastructure Australia in  relation to this program proposal.

In 2019, the Australian Government established the National Water Grid  Authority, which is collaborating with states and territories to identify, plan and deliver nationally important water infrastructure that increases the nation’s water security for primary industry and supports regional growth.

A Perth and south-western coast water security proposal is separately included on the Infrastructure Priority List, as the Western Australian Government has provided detailed evidence of these issues in Perth.
