New Norfolk Wastewater Treatment Plant, Derwent Valley, Tasmania

The New Norfolk wastewater treatment plant is located in the Derwent Valley of Tasmania, Australia, serving the town of New Norfolk and surrounding areas. With a population served of around 5,349, this facility is classified as a small to medium agglomeration under Australian wastewater management standards. The plant is situated near the Derwent River, which flows through the valley and ultimately reaches the Tasman Sea. As an operational facility, the plant is subject to Tasmania's environmental protection regulations, which require appropriate treatment to protect receiving waters. Australian plants of this scale typically employ secondary treatment or equivalent to meet state-based discharge standards. The designed capacity of 1.00 million liters per day suggests the plant is sized to handle the local community's wastewater flows. The plant discharges into the Derwent River system, which is a significant waterway in southern Tasmania. The river supports diverse aquatic life and is used for recreational activities downstream. The treatment plant plays a key role in maintaining water quality in the Derwent catchment, which ultimately drains into the Tasman Sea near Hobart. Proper treatment helps protect the river's ecological health and downstream marine environments.

The New Norfolk plant discharges into the Derwent River, which flows through the Derwent Valley and into the Tasman Sea at Storm Bay near Hobart. The river supports a range of aquatic species, including native fish and invertebrates, and is an important corridor for migratory birds. The catchment includes agricultural and urban areas, making effective wastewater treatment essential to prevent nutrient enrichment and maintain water quality in the river and downstream coastal waters.
