Proston Wastewater Treatment Plant, Queensland | Small Community Facility

Proston wastewater treatment plant is located in the rural town of Proston, Queensland, Australia, within the South Burnett Regional area. The facility serves a small population of approximately 588 residents, reflecting its role in a sparsely populated agricultural region. The plant provides secondary treatment, a standard biological process that significantly reduces organic matter and suspended solids. In Australia, such plants are regulated under state environmental protection laws, with Queensland's Department of Environment and Science overseeing discharge permits to ensure compliance with water quality objectives. The treated effluent is discharged into local waterways, contributing to the health of the Burnett River catchment, which ultimately flows into the Coral Sea. The plant's operation helps protect downstream ecosystems and supports the region's agricultural and recreational water uses.

The plant discharges into the Burnett River catchment, which drains into the Coral Sea off Queensland's coast. This watershed supports diverse aquatic life, including fish species important for local fisheries, and is used for irrigation and recreation. Maintaining low nutrient levels in the discharge is critical to prevent algal blooms in downstream water bodies.
