Tyalgum Wastewater Treatment Plant - New South Wales, Australia

Tyalgum wastewater treatment plant is located in the small town of Tyalgum, New South Wales, Australia, within the Tweed Shire Council area. The plant serves a population of 1,734 and operates under secondary treatment, which is appropriate for its scale and inland setting. As a secondary treatment facility, Tyalgum plant removes organic matter and suspended solids through biological processes, meeting Australian regulatory standards for inland discharge. The plant's annual discharge volume of 448.72 megalitres reflects the modest demand of this rural community. The treated effluent is discharged into local waterways that ultimately flow into the Tweed River system and then to the Tasman Sea. The plant plays a key role in protecting the water quality of the Tweed River catchment, which supports diverse aquatic life and is important for local agriculture and recreation.

Tyalgum lies in the Tweed River catchment, a coastal basin in northern New South Wales. The treated wastewater from the plant enters local creeks that drain into the Tweed River, which flows eastward to the Tasman Sea. The catchment supports subtropical rainforests and estuarine habitats, making effective nutrient removal critical to prevent algal blooms and protect downstream ecosystems.
