Overview
Merrijig Wastewater Treatment Plant in Victoria, Australia, serves a small community of 986 people with secondary treatment. The plant discharges 255.12 megaliters annually, supporting local water quality in the region.
Merrijig Wastewater Treatment Plant is located in the town of Merrijig, Victoria, Australia, within the Shire of Mansfield. It serves a small population of 986 residents, typical of a rural community in the Australian Alps region. The plant is operational and provides secondary treatment, which is appropriate for its scale and inland setting. As a secondary treatment facility, the plant reduces organic matter and suspended solids before discharge. Secondary treatment is standard for Australian plants of this size, often involving biological processes. The plant operates under Victoria's state environmental regulations, which align with national water quality guidelines for inland waters. The treated effluent is discharged into the local catchment, which ultimately drains into the Goulburn River system, part of the Murray-Darling Basin. This basin is ecologically significant, supporting diverse aquatic life and agricultural water supply. The plant's operations help protect downstream water quality in this sensitive river system.
Environmental context
The plant discharges into the local catchment that feeds the Goulburn River, a major tributary of the Murray River within the Murray-Darling Basin. This basin is Australia's largest river system and supports critical ecosystems, including wetlands and migratory bird habitats. The plant's secondary treatment helps mitigate nutrient and pathogen loads, preserving water quality for downstream agricultural and ecological uses.
