Maintaining the network
Maintenance crews have been hard at work clearing vegetation across the network using our specially engineered weed cutter bucket (pictured below).
With more than 3,000 km of supply and drainage channels across the MIA, we prioritise tasks based on:
- Safety for customers, staff, and the community
- Supply or drainage impacts
- Efficiency of programmed works

Work with us to manage weeds
We’re here to support customers who want to reduce or manage weeds on channel banks next to their properties. When done safely, mechanical or chemical controls can improve both farm operations and irrigation access.
We have started using a weed harvester that is helping us to stay ahead of the game with weed management. With an array of attachment tools for aquatic harvesting, excavating, and dredging the harvester is equipped to do it all.
The harvester works on land and water and allows the operator to work in hard to access areas. It rotates on an axis which provides manoeuvrability in tight spaces and is gentle on sensitive areas.
The main weeds that will be targeted include (but are not limited to) Cumbungi, Pond weed, Ribbon weed, and Parrots feather.

Our maintenance focus is on supply constraints and safety issues relating to access to our infrastructure.
We appreciate that many customers like to control weeds on land adjacent to their property, which may include areas around MI infrastructure. If you are considering weed control on MI land, please contact us first we can work together.
