Tulka Wastewater Treatment Plant - South Australia Coastal Facility

Tulka wastewater treatment plant is located on Proper Bay Road in Tulka, South Australia, within the District Council of Lower Eyre Peninsula. It serves a small population of 392 residents and operates as a secondary treatment facility, reflecting its role in a rural coastal community. The plant provides secondary treatment, which is appropriate for its small scale. Under Australian regulatory frameworks, such facilities are typically managed through state-based environment protection authorities, with discharge permits that set limits to protect receiving waters. The plant's operational status is active, and it discharges an annual volume of 101.44 megaliters. The treated effluent is discharged into the local environment near the coast of the Spencer Gulf. This marine environment supports diverse aquatic life, including seagrass meadows and fish habitats. The plant's proximity to the coast necessitates careful management to minimize nutrient and pathogen impacts on the gulf's sensitive ecosystems.

The plant discharges into the Spencer Gulf, a large marine inlet on the South Australian coast. The gulf supports important fisheries and seagrass habitats, which are sensitive to nutrient enrichment. The receiving waters ultimately connect to the Southern Ocean, making the plant's discharge management critical for local marine biodiversity.
