Strathmerton Wastewater Treatment Plant, Victoria, Australia

Strathmerton wastewater treatment plant is located on Bearii East Road in Strathmerton, Victoria, within the Shire of Moira. The plant serves a population of approximately 1,550 and is currently operational. It provides secondary treatment, which is the standard level for inland plants of this scale in Australia. The plant operates under Australia's national regulatory framework, which includes state-based environment protection authorities. In Victoria, the Environment Protection Authority (EPA) Victoria issues discharge permits under the Environment Protection Act 2017. Secondary treatment is typical for small inland communities, ensuring that effluent meets water quality standards before release. The treated wastewater is discharged into the local catchment, which ultimately drains into the Murray River system, a major river basin in southeastern Australia. The Murray River supports diverse aquatic ecosystems and is a critical water resource for agriculture and communities. The plant's discharge volume of 401.16 ML/year is managed to protect downstream water quality and ecological health.

The plant discharges into the Murray-Darling Basin, Australia's largest river system. The receiving waters flow into the Murray River, which supports a range of native fish species and riparian habitats. Downstream, the river reaches the Southern Ocean via the Murray Mouth in South Australia. The basin is ecologically sensitive, with significant environmental flow requirements to maintain wetland and floodplain health.
