Goulburn Valley Water has announced a $6.2 million upgrade to Nagambie’s Water Treatment Plant will be finished in about a year’s time.

The expansion will see facilities built at an entirely new site, while the raw water pump station near Lake Nagambie will be upgraded too.

The project is expected to see the capacity of the plant increase from three megalitres per day to six.

Project manager Neil Healey told reporters this week that the new new site built was needed because that current plant cannot cope.

“It will be a DAFF (Dissolved Air Flotation Filtration) plant which uses a different process of filtration,” he said.

“It takes a heavy mud load and is more conventional.”

Goulburn Valley Water says that in Nagambie’s case, filtering of raw water can be ineffective because of large amount of dirt stirred up by weather events.

The works began this month and are expected to be completed in 12 months.
