Berri Wastewater Treatment Plant, Monash, South Australia

The Berri wastewater treatment plant is located on Hoskin Road in Monash, South Australia, within the Berri Barmera Council area. It serves a small population of 250 people and operates under secondary treatment standards, typical for small inland communities in Australia. As a secondary treatment facility, the plant meets the national guidelines for wastewater management under the Australian Water Quality Guidelines. For a plant of this scale, secondary treatment is appropriate to reduce organic matter and suspended solids before discharge. The plant's annual discharge volume of 64.80 megalitres reflects its small service population. The plant discharges into the local environment within the Murray-Darling Basin, Australia's largest river system. The treated effluent contributes to the region's water cycle, supporting downstream ecosystems that rely on the Murray River and its tributaries. The plant plays a role in protecting the ecological health of this important basin.

The plant is situated inland in the Murray-Darling Basin, which drains into the Southern Ocean via the Murray River mouth near Goolwa, South Australia. The basin supports diverse aquatic life, including native fish species and waterbirds, and is a critical water resource for agriculture and communities. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to algal blooms in the river system.
