Greater Western Water (GWW) has completed $1 million project to install a new ultraviolet (UV) disinfection unit at its Myrniong Water Filtration Plant (WFP).
The new infrastructure will enhance the regular disinfection treatment process at the plant by using powerful UV light to neutralise potentially harmful microorganisms.
Drinking water for Myrniong residents is sourced from Pykes Creek Reservoir and treated at the Myrniong WFP.
GWW General Manager of Growth and Infrastructure, Ian Burton, said adding UV disinfection was beneficial for areas with open drinking water catchments.
“Myrniong’s water supply already meets strict quality guidelines, however UV disinfection provides extra protection as it targets specific bacteria that can be found in open catchment environments,” Mr Burton said.
“It is a proven, effective and sustainable treatment process for drinking water with minimal energy requirements and environmental impacts.”
“This upgrade supports our commitment to provide safe and high-quality drinking water while addressing the unique needs of our different supply systems.”
The UV disinfection process is not expected to change the water’s taste or smell.
Additional UV installations are planned for the Macedon Ranges over 2025–26, as part of a larger upgrade to Romsey WFP and Lancefield WFP.
