Making a valuable water ‘connection’

The tour visits a remediated channel near Cohuna.

PROJECT stakeholders were given a first-hand look at some of Goulburn Murray Water’s $2 billion connections projects during a recent tour.

It covered some of the project’s works in the Torrumbarry irrigation area, including a large pump station suppling about 20 landowners on two different pipelines through six remotely controlled submersible pumps.

It also visited Box Creek Weir, which was completed to generate more reliable irrigation flows to Box and Pyramid Creeks.

The structure, made of 1240 cubic metres of concrete and 300 tons of steel, has a capacity to deliver up to about 2500 megalitres per day through its four irrigation gates.

Another tour highlight was a channel remediation site in which the project remodelled and lined the channel with geosynthetic clay in last year’s winter works program to stop water previously lost to leakage and seepage.

Across the Goulburn-Murray Irrigation District, more than 33kms of irrigation channel were upgraded, more than 35kms of pipeline installed, more than 500 outlets were upgraded or rationalised and more than 250 channel automation sites were installed.

In the Torrumbarry irrigation region alone, more than 16kms of pipeline were installed, 14kms of channel were remediated and more than 50 sites were automated.

This year the project is undertaking a significant annual works program worth more than $200 million, to improve ageing and inefficient irrigation infrastructure.

Connections Project acting early contractor involvement manager Daniel Arnold said last year’s winter works program was one of the largest in the project’s history.

“This was a great opportunity to show people what we’ve constructed in the Torrumbarry area and the works we’ve carried out — they can see it on the ground and in operation,” he said.
