Woodman Point Wastewater Treatment Plant, Henderson, Western Australia

Woodman Point wastewater treatment plant is located in Henderson, within the City of Cockburn, Western Australia. The facility serves a population of 113,085, classifying it as a large agglomeration under Australian wastewater management standards. It is situated near the coast, which influences its discharge considerations. As a major treatment plant, Woodman Point operates under the regulatory framework of the Australian government and the Western Australian Department of Water and Environmental Regulation. For plants of this scale, secondary treatment is typically required, with potential for tertiary treatment to protect sensitive coastal environments. The plant's designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating its ability to handle significant wastewater volumes. The plant's treated effluent is discharged into the marine environment of Cockburn Sound, a coastal embayment that supports diverse aquatic life and is an important ecological area. The discharge is managed to minimize impacts on water quality and marine ecosystems, in line with state and national guidelines for coastal wastewater outfalls.

Woodman Point discharges treated wastewater into Cockburn Sound, a coastal embayment in the Indian Ocean. This marine environment supports seagrass meadows, fish populations, and migratory bird species. The sound is ecologically sensitive, and the plant's operations are regulated to protect water quality and marine biodiversity. The broader drainage area includes the Swan Coastal Plain, with runoff eventually reaching the ocean.
