The three gates had been in service since the structure was built in 1957.

G-MW infrastructure delivery services general manager Warren Jose said the new gates would help improve the structure’s longevity and efficiency.

“Having been in use for more than 60 years, the Cattanach Canal off-take gates had deteriorated significantly and were in need of replacement,” Mr Jose said.

“Replacing the gates will help us maximise the capture potential of Waranga Basin and ensure the long-term functionality of the asset.”

In addition to the fabrication of the new gates and replacement of the existing ones, the $2.37 million works also involved the refurbishment of the gate hoists and the gearboxes that operate the gates.

G-MW constructed a cofferdam upstream of the Cattanach Canal off-take so that the refurbishment works could be carried out in the dry.

The works were timed to occur while Waranga Basin water levels were high and irrigation demands were relatively low, ensuring there would be minimal disruptions to water deliveries.

“We appreciate the patience and understanding from the customers who were affected by these works, as well as motorists impacted by the changed traffic conditions,” Mr Jose said.
