System

The 3,000 km of gravity-fed, earthen channels are the backbone of our water delivery system. These energy-efficient channels transport high-quality irrigation water to over 2,200 farms and landholdings across some 724,00 hectares in southern NSW.

How our irrigation system works

We apply three operating principles to water delivery:
  • Flexibility: Our flexible approach allows us to meet the varying and often unplanned demands of delivering irrigation water to our customers
  • Support: We support and enrich customer experiences by having enquiries resolved or actioned at the point of contact
  • Efficiency: We strive for efficiency to minimise loss, while remaining flexible so we can react quickly and effectively to our customer's irrigation requirements

Water delivery network

Our area of operation stretches from Mulwala in the east to Moulamein in the west, across 724,000 hectares of farmland north of the Murray River.


Water access licenses

We’re licensed to operate by the NSW Government, with 829,097 general security entitlements (non-government). We are also listed as an irrigation corporation in the Water Management Act 2000 (NSW).

We are a private company holding bulk water entitlements on behalf of our shareholders. The Water Management Act 2000 (NSW) includes the requirement for a Water Sharing Plan which describes the rules for the allocation of water. We’re subject to the Water Sharing Plan for the New South Wales Murray and Lower Darling Rivers Water Sources.


Water sharing and storage

The Murray Darling Basin Authority (MDBA) is responsible for planning the Basin’s water resources and River Murray Operations. They manage a shared resource of four major storages with the majority of water stored in Hume Dam.

Under the Water Sharing Plan for the NSW Murray, water is shared between NSW, Victoria and South Australia. NSW and Victoria equally share inflows into Dartmouth, Hume Dam and the Menindee Lakes storage systems. NSW and Victoria must then equally supply South Australia with entitlement flows each month.

The water available to NSW has to be shared with many competing users. Water can only be shared when available water and system commitments have been determined. In NSW, Water Sharing Plans have been regulated in each catchment to set priorities for water distribution in accordance with the class of user access licence.
