Manning Point Wastewater Treatment Plant, New South Wales

Manning Point wastewater treatment plant is located on Oystercatchers Lane, Mitchells Island, within the Mid-Coast Council area of New South Wales, Australia. The facility serves a small population of 741 residents and operates under secondary treatment standards, which is typical for smaller coastal communities in the region. The plant's secondary treatment process reduces organic matter and suspended solids before discharge. As a facility serving fewer than 10,000 people, it aligns with Australian state regulations that require appropriate treatment to protect receiving environments. The plant's operational status is active, and it manages an average daily discharge volume of approximately 192 megaliters per year. The treated effluent is released into the local coastal environment, likely via a nearby river or estuary that drains into the Tasman Sea. This coastal discharge requires careful management to safeguard marine ecosystems and recreational water quality. The plant plays a key role in maintaining the ecological health of the Manning River catchment and downstream coastal waters.

The plant discharges into the Manning River catchment, which flows into the Tasman Sea near Manning Point. This coastal zone supports diverse marine life, including fish nurseries and migratory shorebirds. The secondary treatment helps reduce nutrient loads that could otherwise contribute to algal blooms in the estuary.
