Dunolly Wastewater Treatment Plant, Victoria | Secondary Treatment Facility

The Dunolly Wastewater Treatment Plant is located in the Shire of Central Goldfields, Victoria, Australia, serving the small community of Dunolly with a population of about 1,245. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under Australia's regulatory framework for wastewater management, which includes state-level environment protection authorities. For small inland communities like Dunolly, secondary treatment is standard to protect local waterways and meet environmental guidelines. The treated effluent is discharged into the local catchment, which eventually drains into the Murray-Darling Basin, Australia's largest river system. This basin supports diverse aquatic ecosystems and is critical for agriculture and water supply. The plant's operation helps maintain water quality in this important watershed.

The Dunolly plant discharges into the local watershed, part of the Murray-Darling Basin, which drains into the Southern Ocean via the Murray River mouth. The basin is ecologically significant, supporting native fish species, waterbirds, and riparian vegetation. Effective wastewater treatment is essential to prevent nutrient pollution and protect downstream habitats.
