Brunswick Junction Wastewater Treatment Plant, Brunswick, Western Australia

Brunswick Junction wastewater treatment plant is located in Brunswick, a town in the Shire of Harvey, Western Australia. The facility serves a population of approximately 1,724 residents and operates under the regulatory framework of the Australian state of Western Australia, which follows the National Water Quality Management Strategy. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant's discharge volume is 446.21 megalitres per year, reflecting the scale of the community it serves. Secondary treatment is the standard for inland and coastal plants in Australia, meeting the requirements set by the Department of Water and Environmental Regulation. The population served indicates a small-scale facility. The treated effluent is discharged into the local environment, likely reaching the Leschenault Estuary or the Indian Ocean via nearby waterways, given the plant's proximity to the coast. This discharge supports the ecological health of the region, which includes wetlands and coastal habitats that are important for migratory birds and aquatic life. The plant plays a key role in protecting these sensitive ecosystems from untreated wastewater.

The plant discharges into the coastal watershed of Western Australia, likely flowing into the Leschenault Estuary or directly to the Indian Ocean. This region supports diverse aquatic life, including fish, crustaceans, and migratory shorebirds. The estuarine and coastal environments are ecologically sensitive, requiring careful management of nutrient and pathogen loads to prevent eutrophication and maintain water quality.
