What is Victoria's water grid?

The water grid works much like our road network, connecting sources such as dams, reservoirs, irrigation districts and the desalination plant via infrastructure including pipes and pumps, and natural elements like rivers.

The water grid includes:

  • the capture, production and storage infrastructure (such as dams, reservoirs, weirs, groundwater extraction locations and the Victorian Desalination Project)
  • the delivery infrastructure (such as channels, pipes, pumps and the waterways used to deliver water)
  • the arrangements by which water can be purchased and sold through the water markets and allocated through the water entitlement framework.

Vision

Maximise community benefit from a connected grid that contributes to water affordability and underpins water security.

Forward view of resources as part of the Water Grid Biennial Statement

Develop a suite of data and information about state-wide trends, to provide assurance we are prepared for a future with less water.

Completed: Development of the forward view methodology.

Ongoing: Produce forward view.

Stress testing the water grid as part of the Water Sector Climate Change Adaptation Action Plan

Develop an understanding of the impact of extreme shocks to the water grid and what steps we need to take to build resilience into the system.

Completed: Stress test of the south central Victorian water grid.

Ongoing: Stress test of the Victorian water grid.

Sharing water effectively as part of the Central and Gippsland Region Sustainable Water Strategy

Making sure the arrangement and rules that govern all parties involved in water security, understand and encourage whole-of-system optimisation of the grid at the lowest economic cost.

Ongoing: Sharing water effectively

Strategic grid augmentation plan as part of the Central and Gippsland Region Sustainable Water Strategy

Making sure an agreed upon process for making sound decisions and about augmenting the grid, including to develop a portfolio of potential augmentation options.

Ongoing: Strategic grid augmentation plan.

How does the grid work?

Victoria’s water grid is among the states most important infrastructure. More specifically the water grid includes:

  • The capture production and storage infrastructure such as dams, reservoirs, groundwater extraction locations and the Victorian desalination project.
  • The major delivery infrastructure such as channels, pipes pumps, and the waterways used to deliver water.
  • The arrangements by which water can be purchased and sold through the water markets a water entitlement framework.

What challenges does Victoria's water supply face?

The grid helps tackle some of our water resource challenges by building resilience in the connected system for communities and the environment.

How is the grid helping to address urban water challenges?

There’s a number of ways the grid can tackle our urban water challenges, we’re working with industries and community partners to develop a strategic augmentation plan to make sure water is available when needed.

Explore the different pressures and augmentation plans around Victoria on the dashboard.

How is the grid helping to address rural water challenges?

The way we use and deliver water for irrigation is changing and so is the amount of water available. The grid can provide infrastructure that may help rural communities adapt to changing needs.

Challenges

Total water availability

The impacts of climate change may drier future with less rainfall and lower inflows into our storages to support water allocations for all water users including irrigators.

Supplying and delivering water

Getting water to where and when it is needed is becoming more difficult in some of our major river systems with different supply points becoming less reliable and reductions in capacity in some areas.

Changes in demand for water

With less reliable rainfall and changing industry demands where and when people need water for agriculture and in rural communities is changing.

Accessing available water

With a drying climate, it is more important than ever that rural users understand how to access and make the most out of their water, including how to manage risk by buying, selling or holding water.

Potential solutions

Modernisation of existing infrastructure

Investments in existing infrastructure to reduce losses, including seepage and evaporation losses, and ensure water delivery is as efficient and reliable as possible.

Infrastructure and alternative water

New pipes or infrastructure to increase the volume of water supplied, and access to all available water sources can improve water security, such as utilising recycled water for irrigation in the Werribee irrigation district.

On-farm efficiency

Improving on-farm water efficiency enables farmers to make the most out of available water while providing benefits to the Victorian community.

Effective water markets

Effective water markets provide rural water users the certainty and flexibility to manage how they use their water. Tools like carryover and trade are important for many rural users in getting the most out of the available water.

How does the grid support Traditional Owner, environmental and recreational values?

By working with Traditional Owners, industries and community partners the grid can help restore our waterway’s ecological health.

This will enhance the social, cultural, recreational and environmental values important to Victorians. Explore the work being done to benefit our waterways and communities.
