Beenyup Wastewater Treatment Plant, Craigie, Western Australia

Beenyup wastewater treatment plant is located in Craigie, a suburb of Perth in Western Australia, and serves a population of around 287,000. The plant is part of the Water Corporation's infrastructure, managing wastewater from the northern suburbs of Perth. As a major facility, it plays a key role in the region's water cycle. The plant operates under Australia's regulatory framework, which requires advanced treatment for coastal discharges to protect marine environments. Plants of this scale typically employ secondary or tertiary treatment to meet stringent environmental standards. The designed capacity is 1.00 (likely in megaliters per day), indicating a large-scale facility. The treated effluent is discharged into the marine environment of the Indian Ocean, via an ocean outfall. This discharge point is subject to strict environmental monitoring to minimize impact on coastal ecosystems, including seagrass meadows and marine life. The plant's location within 50 km of the coast underscores the importance of effective treatment to protect the sensitive coastal waters.

The plant discharges treated wastewater into the Indian Ocean off the coast of Western Australia. The receiving waters support diverse marine ecosystems, including seagrass beds and coral reefs, which are sensitive to nutrient pollution. Effective treatment is critical to maintaining water quality and protecting the region's biodiversity, which includes species such as dolphins and sea turtles.
