Winter Works

Each irrigation off-season GMW undertakes maintenance works on the channel systems that supply our irrigation districts.

From 15 May 2021, we are undertaking an $8 million program of maintenance and capital works and approximately 22,000 labour hours to enhance the capacity of our irrigation network.

Some of the works to be undertaken in 2021 include:

  • draining channels to remove silt build-up and other obstructions
  • treating channels with approved herbicides to remove weeds
  • repairs to various structures such as bridge crossings and drainage culverts and flow regulators, and
  • remodelling channel banks to ensure these channels lifespan is maintained.

The works will be complete by early August to allow channels to be recharged and irrigation supply recommence by 15 August 2021. The safety of our staff, customers and the local community is the priority and with a large winter works scheduled for 2021, safety will continue to be at the forefront for the successful delivery of the winter works program this year. Maintenance of our channel delivery network is crucial to ensuring the network provides a reliable supply during the irrigation season. Works vary from site to site and can include channel bank and gate repairs, bridge works, desilting and weed control works.

To successfully complete these works, GMW is required to drain sections of the channel network. This means some customers will not have access to water from the channel network and will need to make alternative arrangements for water supply during the non-irrigation period. Water supplied from the channel network is only guaranteed during the irrigation season.

An increase in road traffic may be experienced during this time so road users are encouraged to take care while travelling on roads near works sites.
