PIIOP Round 3

Our PIIOP Round 3 project has received approval for funding of up to $114.8 million from the Australian Government’s Private Irrigation Infrastructure Operators Program (PIIOP) in NSW

Project summary

PIIOP Round 3 is focused on upgrading larger infrastructure within the main canals of our network, completing our modernisation journey.

Some iconic agricultural assets are being improved under this project, including:

  • Mulwala Canal – this irrigation channel forms the backbone of our water delivery system. Gravity-fed from Lake Mulwala, it runs 2,880kms and is the longest canal in the Southern Hemisphere.
  • Lawson Syphons – built in the 1930s as a way to send water underneath the Edward River to service the Deniboota farming region, the two iconic syphons are integral to meeting the water needs of the eastern and western parts of our operational footprints.
  • Berrigan Canal – an offshoot of the Mulwala Canal, it services regions south of Jerilderie and runs into the Billabong Canal and Billabong Escape.
  • Edward River Escape – a key agricultural asset that allows us to monitor, regulate and analyse flows into the Edward River.

These upgrades will provide greater control and extend the life of larger infrastructure across the main canals of our network. They have improved system control and allowed us to harvest rain water events. The project will allow strategic draining and winter watering periods, which means more water put to better use for the region.

PIIOP 3 works will merge with earlier upgrades that increased flow rates and improved ordering flexibility for customers.

There is a mixture of major regulators and escapes within the project scope.

2017 Berrigan Canal works

During winter 2017 six structures were upgraded along the Berrigan Canal.

These works began on May 1 and were fully commissioned by August 8.

In that time, 15,000 working hours were put into the project which comprised more than 80 tonnes of reinforcing steel and 900 cubic metres of concrete.

The Berrigan Canal diverts off the main Mulwala Canal that forms the backbone for the rest of our water delivery system. The Billabong Canal is fed water via the Berrigan Canal, so infrastructure upgrades to extend the life of assets and modernise its technology were vital.

2018 scope of works

The PIIOP 3 works for 2018 stretch from the Wakool system through to the beginning of the Mulwala Canal at the Mulwala Offtake. These upgrades will provide greater control and extend the life of larger infrastructure across the main canals of our network. The works began in 2017. They have improved system control and allowed us to harvest rain water events. PIIOP 3 works will merge with earlier upgrades that increased flow rates and improved ordering flexibility for customers. There is a mixture of major regulators and escapes within the project scope. Works will also be carried out on three regulators in the Wakool system.
