Winneke Treatment Plant
Depending on demand, about 20% of Melbourne's water is treated at Winneke Treatment Plant, Sugarloaf Reservoir. The water requires full treatment as it is not drawn from protected catchment areas.
Winneke Treatment Plant was commissioned in November 1980 and represented a milestone in the history of Melbourne’s water supply system, as it was the first time that fully treated water had been introduced into the water supply. Winneke Treatment Plant supplies water to City West Water and Yarra Valley Water customers.
Winneke Treatment Plant is registered as a Major Hazard Facility under the Occupational Health and Safety (Major Hazard Facilities) Regulations 2000. This is because of the quantity of chlorine stored on-site for disinfection. The plant has a comprehensive Safety Management System and Emergency Plan. This includes a formal safety notification procedure for local residents in case of an emergency.
