A project to breathe new life into a key water storage reservoir at Mansfield is nearing completion.

The remediation works are at the Mansfield No 3 reservoir, which acts a raw water balancing storage for the Mansfield Water Treatment Plant, in conjunction with supplies from two other major nearby off-river storages.

Works to rehabilitate and stabilise the 34 megalitre lagoon’s embankments have been carried out, including placing an additional 5000 cubic metres of rock to provide additional bank support.

The $4.7m project has been carried out after regular dam inspections showed there was opportunities to improve the reliability of the storage.

As well as embankment works, upgrades have also been completed on the dam’s spillway, filter improvements and pipeline works.

Goulburn Valley Water Acting Managing Director Daniel Hughes said proactively managing upgrades to GVW’s off-river supply dams was critical to ensure future service reliability.

“The upgrades ensure our water storage is in line with national dam risk assessment guidelines and ensures we’re proactively managing any risks,” Mr Hughes said.

Works were carried out in two phases, with the majority of bank works happening during winter’s lower water demand period.

The reservoir works are the first of many upgrades planned over the next five years in Mansfield to cater for the region’s anticipated population growth.
