The Problem
Outfall
Effluent
Australia's beautiful coastline, ecosystems and beaches are under a huge threat from ocean polluters. The worst offenders are ocean outfalls.
Australia's 144 ocean and estuary outfall pipelines dump billions of litres of semi-treated effluent; domestic, industrial, trade and abattoir waste onto or near the shoreline every single day.
Trade Waste
Effluent outfalls across Australia often contain wastewater from industries who pay a fee to Water Authorities to dump their sometimes toxic waste into the sewage system.
Often the sewage systems currently in our towns and cities were designed decades ago, so treatment processes were not designed to manage pollutants and chemicals that now enter the system.
The worst Trade Waste industries include tanneries, hospitals, dentistry, morgue and pharmaceuticals from which all sorts of by-products and pollutants are flushed into the system.
Climate Change
Australia is a dry continent. Water is a valuable commodity. Scientists and meteorologists are forecasting increased times of drought, and infrequent patterns of flooding rains. What does this mean for our wastewater system? Increased pressure on ageing systems.
Dry times mean concentrated sewage flows, restrictions on water use and increase in water costs. Infrequent flooding rains mean large volumes of water swamping sewers that are not designed for huge flows resulting in treatment processes failing and pollution of our natural water systems.
