Fairfield Wastewater Treatment Plant, Sydney, New South Wales

Fairfield wastewater treatment plant is located in Wetherill Park, Sydney, within the Fairfield City Council area of New South Wales, Australia. The plant serves a population of around 304,000, making it a large-scale facility in the Sydney metropolitan region. As a major treatment plant, it is expected to meet stringent environmental standards under Australian regulations, including the National Water Quality Management Strategy and state-level guidelines. The plant's designed capacity is 1.00 (likely in megalitres per day or similar), indicating a substantial infrastructure investment to handle the wastewater from a significant urban population. The treated effluent from the plant is discharged into the local water system, ultimately contributing to the Parramatta River and Sydney Harbour. This discharge supports the ecological health of the harbor and downstream marine environments, which are important for biodiversity and recreational activities in the Sydney region.

The plant's discharge flows into the Parramatta River catchment, which drains into Sydney Harbour, a major estuary and port. The harbor supports diverse aquatic life, including fish, crustaceans, and migratory birds. Effective treatment is critical to protect water quality in this ecologically sensitive and heavily used waterway.
