Uki Wastewater Treatment Plant, Smiths Creek, New South Wales

Uki wastewater treatment plant is located in Smiths Creek, within the Tweed Shire Council area of New South Wales, Australia. The facility serves a small community of 2,393 residents and operates under secondary treatment standards, which is appropriate for its scale and inland setting. As a secondary treatment plant, Uki meets the typical Australian regulatory requirements for inland wastewater facilities. The plant's discharge volume of 619.11 megaliters per year reflects the modest population served. Australian wastewater treatment standards for small communities emphasize reliable secondary treatment to protect receiving water quality. The plant discharges into the local catchment, which ultimately drains to the Tweed River system and then to the Tasman Sea. This inland location, more than 10 km from the coast, reduces direct marine impact but requires careful management to protect freshwater ecosystems and downstream water quality.

The plant discharges into the Smiths Creek catchment, part of the Tweed River basin, which flows into the Tasman Sea near the border of New South Wales and Queensland. The Tweed River supports diverse aquatic life, including migratory fish species, and its estuary is ecologically sensitive. The plant's secondary treatment helps maintain water quality in this coastal river system.
