Charlton Wastewater Treatment Plant, Victoria, Australia

Charlton wastewater treatment plant is located in the small rural town of Charlton, in the Shire of Buloke, Victoria, Australia. The facility serves a population of approximately 1,136 residents, reflecting the scale of a small agglomeration. As an operational plant, it plays a key role in managing municipal wastewater for this inland community. The plant provides secondary treatment, which is the standard level required under Australian wastewater management guidelines for small communities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is recorded at 293.84 megalitres per year, indicating consistent operation. The treated effluent is released into the local watershed, which ultimately drains into the Murray-Darling Basin, Australia's largest river system. This basin supports extensive agricultural activity and diverse aquatic ecosystems. The plant's operations are regulated under Victorian state environmental protection laws, ensuring compliance with discharge standards to protect downstream water quality.

The plant discharges into the Avoca River catchment, a tributary of the Murray River within the Murray-Darling Basin. This basin is ecologically significant, supporting wetlands, floodplains, and migratory bird habitats. Downstream, the Murray River flows into the Southern Ocean via the Murray Mouth in South Australia. The region's semi-arid climate makes water quality management critical for sustaining agricultural and ecological needs.
