Aquatic weed treatment to improve channel capacity in Central Goulburn Irrigation Area

Wednesday 24 May, 2017

Goulburn-Murray Water (GMW) will be carrying out an aquatic weed treatment program this winter to ensure customers continue to have a reliable water supply during the irrigation season.

The treatment will take place in some channels within the Central Goulburn Irrigation Area between June 5 and August 14, which will mean there will be no access to channel water during this time.

Customers are advised to make alternative arrangements for water supply. While some water will remain in the channel, this will be treated water and not fit for use. 

Water supplied from the GMW channel network is only guaranteed during the irrigation season.

GMW Central Goulburn Customer Service Manager Greg Shannon said the treatment is designed to ensure better flow rates and return design capacity to the channels.

“The static water will be injected with Endothall, a herbicide proven to effectively treat aquatic weeds,” Mr Shannon said.

“We expect this will only affect a small number of people, who we have written to about the upcoming treatment program.

“We are grateful for our customers’ support and understanding as we continue to improve our water delivery service standards.”

While the treatment has a low toxicity to humans and mammals, GMW advises customers to ensure livestock do not ingest the channel water. It is also recommended that customers do not spray horticulture and broadacre crops with channel water during this time.

Aquatic weeds in our irrigation network affect water flow, promote silting and cause problems with automated regulators, impacting water delivery to customers.
