It serves a small population of approximately 1,277 residents, reflecting its role in a rural community. The plant is operational and provides secondary treatment, which is appropriate for a facility of this scale. As a secondary treatment plant, Kojonup uses biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 330.47 megalitres per year indicates its operational scale. In Australia, wastewater treatment plants are regulated under state and national guidelines, including the National Water Quality Management Strategy, which sets standards for effluent quality and environmental protection. The treated wastewater from Kojonup is discharged into the local watershed, which ultimately drains into the broader South West drainage division of Western Australia. This region features intermittent rivers and wetlands that support diverse aquatic life. The plant's operation helps protect downstream water bodies from nutrient pollution and maintains the ecological health of the surrounding environment.

The Kojonup plant discharges into the local catchment within the South West drainage division of Western Australia. This region is characterized by seasonal rivers and wetlands that flow into the Southern Ocean. The area supports a variety of native species, including waterbirds and aquatic plants, and is part of a semi-arid to Mediterranean climate zone. Proper treatment is essential to prevent nutrient enrichment and maintain water quality in these sensitive ecosystems.
