It serves a small population of 599 residents as part of the Derwent Valley municipal infrastructure. The plant is situated inland, more than 10 km from the coast, and operates under Australian environmental regulations. The plant provides secondary treatment, which is appropriate for its small scale. Under Australian guidelines, secondary treatment is standard for communities of this size to reduce organic matter and suspended solids before discharge. The plant processes an annual discharge volume of 155.10 ML, reflecting the modest population served. The treated effluent is released into the local watershed, which ultimately drains into the Derwent River and then into the Tasman Sea. The Derwent River estuary supports diverse aquatic life and is an important ecological corridor. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the river system.
