Overview
Penna and Barwick wastewater treatment plant in Hobart, Tasmania, Australia, provides secondary treatment for a small population of 964. It discharges treated wastewater near the coast, with a daily volume of 249.33 megaliters.
Penna and Barwick wastewater treatment plant is located in the suburb of Penna, part of the Hobart metropolitan area in Tasmania, Australia. The facility serves a small population of approximately 964 residents and operates under secondary treatment standards, which involve biological processes to reduce organic matter and suspended solids. The plant is situated near Orielton Lagoon, a coastal lagoon system, and discharges treated effluent into the local environment. As a secondary treatment plant, Penna and Barwick meets the standard requirements for municipal wastewater treatment in Australia, which are regulated under state and national guidelines. The plant's discharge volume of 249.33 megaliters per day indicates a moderate flow relative to its small service population. The plant's operational status confirms it is actively managing wastewater for the community. The plant's proximity to the coast (within 10 km) means its discharge can influence the sensitive coastal ecosystem of Orielton Lagoon and the broader Derwent Estuary. The lagoon supports diverse aquatic life and migratory birds, making proper treatment essential to protect water quality and ecological health. The treated effluent ultimately flows into the Tasman Sea, contributing to the region's marine environment.
Environmental context
Penna and Barwick plant discharges into Orielton Lagoon, a coastal lagoon that connects to the Derwent Estuary and ultimately the Tasman Sea.
