Kenilworth Wastewater Treatment Plant, Sunshine Coast Regional, Queensland

Kenilworth wastewater treatment plant is located in the Sunshine Coast Regional area of Queensland, Australia, serving a population of approximately 2,081 residents. The facility operates under secondary treatment standards, ensuring effective removal of organic matter and solids from municipal wastewater. As a secondary treatment plant, Kenilworth meets the typical requirements for small Australian communities under the National Water Quality Management Strategy. The plant's discharge volume of 538.40 megaliters per year reflects its scale and the local demand for wastewater services. The treated effluent from Kenilworth is discharged into the local watershed, which ultimately drains into the Mary River system and then to the Great Sandy Strait, a coastal estuary of ecological significance. The plant plays a key role in protecting downstream water quality and supporting the region's aquatic ecosystems.

The plant discharges into the Mary River catchment, which flows into the Great Sandy Strait, a large coastal estuary in Queensland. This estuary supports diverse marine life, including seagrass beds and fish nurseries, and is an important migratory corridor for shorebirds. The secondary treatment helps reduce nutrient and pathogen loads, safeguarding the ecological health of the downstream environment.
