30 November 2017

Western Water is upgrading Rosslynne Reservoir’s three million litre drinking water tank, as part of its capital works program.

The $625,000 project to refurbish the tank includes a new roof structure and roof supports.

“We regularly inspect all our assets to make sure they are in excellent condition,” Western Water’s Managing Director Neil Brennan says.

“Routine internal inspections by divers showed we needed to do some work on this tank, which was built in the 1990s.”

“The issues with the tank had no impact on the safety and quality of the drinking water, but were more about improving the structure,” Mr Brennan says.

The tank was drained and its roof removed for a full engineering assessment. Work included encasing internal steel columns in concrete, building a new roof structure and installing new access points.

Mr Brennan says the project, which has not interrupted water supply from the reservoir’s Water Filtration Plant, will extend the life of the tank for another 25 years.

“We expect the project to be finished on schedule and the tank back in service before the peak summer water use period.”

Rosslynne Reservoir is the main drinking water source for the Macedon Ranges, with a capacity of more than 25,000 million litres.
