Weeding out threats to our waterways

Protecting the health of our waterways is core to our business at Melbourne Water and that’s why we have stringent protocols in place when it comes to the controlled spraying of targeted weeds.

Work practices and the use of equipment are carefully managed, dependent particularly on the conditions of the site as well as prevailing weather such as wind and possible rainfall.

Pre-planned spraying methods take into account the type of weed itself, the extent of coverage and how a site can be safely accessed, with a continuing focus at Melbourne Water on seeking more environmentally friendly alternatives to spraying such as mowing, brush cutting or heat weeding. We aim to use the minimum treatment for each targeted weed whenever possible.

“All staff undertaking spray activities are certified to use chemicals in public areas to avoid off target impacts. In addition, Melbourne Water undertakes detailed assessments, broad-scale surveys and research to further understand and protect waterway environments when it comes to the control of targeted weeds,” said Victoria Penko, Head of Waterway and Catchment Services North West.

“Through our research we are always looking to minimise the impacts of weed control as part of our dedicated, ongoing improvement program to reduce risk to the environment.”

Our staff are working hard to look after 25,000 kilometres of waterways across Greater Melbourne, carrying out vital projects such as revegetation work, rubbish removal and weed control.

Left unchecked weeds can continue to spread, outcompeting and destroying vegetation and animal habitat within and beyond waterways.

Through our Healthy Waterways Strategy 2018, Melbourne Water is constantly tending to rivers, creeks and surrounding land. By carefully managing targeted weeds people can expect healthier waterways, which importantly are part of a system of reserves that maintain habitat for Australia’s unique and diverse flora and fauna. The health of our waterways and land is essential to our native wildlife, and to our way of life today, tomorrow and for generations to come.
