Binjari Wastewater Treatment Plant - Town of Katherine, Northern Territory

Binjari wastewater treatment plant is located along Victoria Highway in Manbulloo, near the Town of Katherine in Australia's Northern Territory. The facility provides secondary treatment for a population of approximately 746 residents, serving the local community as part of the region's municipal wastewater infrastructure. The plant operates under Australia's regulatory framework for wastewater management, which requires secondary treatment for inland communities of this scale. With an annual discharge volume of 192.99 megalitres, the facility meets the treatment standards expected for small agglomerations under the National Water Quality Management Strategy. The treated effluent is discharged into the local catchment, which ultimately drains into the Katherine River system. This river flows through the tropical savanna region before joining the Daly River, which discharges into the Timor Sea. The plant's operations help protect the ecological health of these downstream water bodies.

The treated effluent from Binjari enters the Katherine River catchment, part of the Daly River basin that flows through the Northern Territory's tropical savanna. The Katherine River supports diverse aquatic life, including barramundi and freshwater turtles, and is an important cultural and recreational resource for the region. The river system eventually reaches the Timor Sea, contributing to the coastal marine environment.
