Major works for Mildura lock and weir

Saturday, 14th February, 2015

The Mildura weir pool will be lowered for about 10 weeks from mid to late May to allow structural repairs. The Mildura weir pool will be lowered for about 10 weeks from mid to late May to allow structural repairs.

The Mildura lock will be closed and the weir pool lowered from late autumn while major, long-standing maintenance work is completed.

This will involve closing the lock for up to four months for detailed inspection and repair work.

MDBA head of River Management David Dreverman said the job had to be done every 15 years to prevent breakdowns.

He said it also made sense to do the work at the same time as the work on the Mildura weir.

“The work on the weir includes structural repairs and installation of six new trestles,” Mr Dreverman said in a statement.

“This will require the weir pool to be lowered for about 10 weeks from mid to late May,” he said.

“The timing will be finalised in the coming weeks, after speaking with local community and industry groups.

“We’re very aware of the community’s needs around the river, so it’s important that we take advice from local tourism, irrigation and other groups to minimise the impact.

“Our aim is to start the lock works after the busy Easter period and finish the weir upgrade before the irrigation season starts.

“We’ll only know the likely duration of work on the lock once itís empty and we’re able to do a thorough inspection.”

Mr Dreverman said work at the lock would include things like taking off the main gates for sandblasting and repainting, updating the valves and checking the integrity of the lock chamber.

“The purpose of the weir upgrade is to improve the safety of operations by installing new mechanised trestles to regulate the pool height and flow of water through the weir. This is a job that has been done manually for the past 90 years using large timber drop bars.”
