Modernisation Projects

Infrastructure Modernisation

Major infrastructure projects are underway to renew ageing water delivery infrastructure and generate water savings to reduce the impacts of the Murray-Darling Basin Plan. These projects were identified in the development of a Modernisation Plan that we prepared in 2009 with funding from the Australian Government.

The Modernisation Plan considered a range of options available to us to respond to the challenges facing the irrigation industry, one of which included increasing the efficiency of the irrigation distribution system to drive regional development, investment and growth, that included the following projects: 

  • Lake Wyangan modernisation project (completed)
  • Hanwood (completed)
  • Wah Wah stock and domestic pipeline project (in progress)


    The Private Irrigation Infrastructure Operators Program in New South Wales (PIIOP-NSW) aims to improve the efficiency and productivity of water use and management of private irrigation networks to deliver water savings for the environment. Water entitlements resulting from water savings generated from eligible projects, both off and on-farm, will help to secure a sustainable future for irrigation communities.

    PIIOP Round 1

    In 2010 Murrumbidgee Irrigation received funding of $50 million from the Australian Government to upgrade ageing water delivery infrastructure in Lake Wyangan in exchange for water savings. 

    This project has delivered a modern delivery system that will substantially increase the maximum system capacity for Lake Wyangan customers. The project replaced 15.8 kilometres of concrete lining and 13.8 kilometres of open channels with gravity pipelines to reduce water losses and improve system delivery efficiencies. Manually operated regulators will be replaced with automated regulating structures and gates to deliver a consistent flow rate. Dethridge Wheels were be replaced with more accurate electronic flow meters.

    Construction commenced in May 2013 and was completed in November 2014.

    PIIOP Round 2

    In December 2011, the Australian Government announced $149.6 million in funding for Murrumbidgee Irrigation Limited (MI) under the Round 2 of PIIOP-NSW to upgrade both off-farm and on-farm infrastructure in exchange for water savings. This funding supports integrated water infrastructure modernisation projects in Hanwood, Bilbul, Leeton, Yenda and the Wah Wah stock and domestic district.These projects are being progressively developed and delivered.

    PIIOP Round 3

    In 2016, Murrumbidgee Irrigation received funding of $84.8 million and will transfer water entitlements that will return 9489 ML every year on average over the long-term to the Australian Government to help bridge the gap in the Murrumbidgee catchment. 

    This project is expected to be completed 2019 and involves: 
    • channel lining with clay or ethylene propylene diene monomer (EPDM) rubber lining, including reforming earthen and concrete channels 
    • channel automation, including automation of the main canal regulators, Sturt Canal and unmetered escapes 
    • replacing inefficient channel systems with gravity pipelines and pumped stock and domestic systems 
    • replacing dethridge wheels with compliant meters.
