Caemaine Wastewater Treatment Plant, Castlemaine, Victoria

Caemaine wastewater treatment plant is located in Castlemaine, Victoria, Australia, serving a population of approximately 12,488. The plant is operational and situated inland, contributing to the region's wastewater management infrastructure. As a facility serving a medium-sized agglomeration, Caemaine operates under Australian regulatory standards, which typically require secondary treatment for inland plants to protect water quality. The plant's treatment processes align with national guidelines for sustainable wastewater management. The treated effluent from Caemaine is discharged into the local watershed, which ultimately drains into the Murray-Darling Basin, Australia's largest river system. This basin supports diverse aquatic ecosystems and is vital for agriculture and communities downstream.

Caemaine's treated effluent enters the local catchment, which flows into the Loddon River, a tributary of the Murray River within the Murray-Darling Basin. This basin is ecologically significant, supporting a range of native fish species and wetlands. The plant's inland location means its discharge contributes to river flows that sustain downstream environments, including agricultural and natural habitats.
