Leonora Wastewater Treatment Plant, Western Australia | Secondary Treatment for Small Community

Leonora wastewater treatment plant is located in the remote town of Leonora, Western Australia, within the Shire of Leonora. The plant serves a small population of 250 residents and operates under secondary treatment standards, ensuring basic pollutant removal before discharge. As a secondary treatment facility, the plant meets the typical requirements for small Australian communities. The plant's discharge volume of 64.80 ML/year indicates consistent operation. Australian wastewater treatment plants are regulated under state and national guidelines, with the Department of Water and Environmental Regulation overseeing compliance in Western Australia. The plant discharges into the local environment, likely into a dry creek bed or evaporation basin common in the arid Goldfields region. The area is part of the Lake Carey catchment, which drains internally without reaching the ocean. The plant plays a crucial role in protecting groundwater and preventing contamination of the fragile desert ecosystem.

Leonora lies in the arid Goldfields region of Western Australia, where surface water is scarce and most drainage is internal. The plant's discharge likely flows into a local ephemeral creek or evaporation pond, eventually reaching Lake Carey, a large salt lake system. This terminal lake supports migratory bird species and is ecologically sensitive to nutrient inputs. The plant's secondary treatment helps minimize impacts on this fragile desert watershed.
