Mundaring Weir closure works to help save water

PARTS of the Bibbulmun track will be diverted and the walkway at the Mundaring Weir will be closed from next month as part of work to reduce the surface area of the dam in a bid to save water.

The upgrade of the intake tower and associated pipework will take place between April and November and is expected to save 1.5 billion litres of water per year from evaporation.

A Water Corporation spokesman said the Mundaring Weir played a vital role in supplying water to towns in our Goldfields and Agriculture areas.

“To ensure we can meet demand during peak flow periods, like many of our dams, the Water Corporation transfers water produced from deep groundwater and desalination into the reservoir,” the spokesman said.

“Once complete, this project will allow more flow to leave the reservoir at a reduced surface level.

“Without the need to top up the dam, this will allow over 8 million litres of water to be used elsewhere across the Integrated Water Supply Scheme.”

To ensure public safety during construction, the dam walkway will be closed and the Bibbulmun Track will be diverted until November 30.
