Australia's Water Pollution: Strategies For A Sustainable Future

Water pollution is a pressing issue in Australia, the world's driest inhabited continent, where less than three per cent of the Earth's total supply of water is fresh water. Water pollution can be caused by agriculture, forestry, new developments and mining activities, which lead to land being cleared, excavated and eroded. Rainwater then carries soil, fertilisers and chemicals into creeks and rivers, causing siltation, excessive plant growth and the death of aquatic plants and animals. To stop water pollution in Australia, it is important to reduce the use of single-use plastics, increase the number of water refill stations and manage water quality by knowing the current and desired uses of particular waterways.

Reducing plastic waste

Water pollution is a pressing issue in Australia, the world's driest inhabited continent, where less than three per cent of the Earth's total supply of water is freshwater. To reduce water pollution, it is essential to focus on reducing plastic waste.

Plastic waste is an issue for both human and environmental health. In recent years, Australian states and territories have introduced bans on different types of single-use plastics, such as plastic bags, coffee cups and lids, straws, and takeaway boxes. However, there is currently no national plan to put a blanket ban on these products, and recycling plastic is inefficient, expensive, and hazardous.

To significantly reduce plastic waste, it is important to focus on the top six culprits of single-use plastics. These include plastic bags, coffee cups and lids, straws, takeaway boxes, cutlery, and microbeads. By encouraging people to bring their own bottles and providing refill options, the need for plastic bottles can be reduced.

Additionally, all Australians, businesses, and governments have a role to play in fixing the plastic problem. This includes making conscious choices about the products we buy, supporting visionary businesses, and improving our disposal habits. By sending important signals to businesses and the government, we can revolutionise how plastic is used and protect the ocean's animals.

Finally, policies that focus on reducing the production and consumption of plastics, rather than just recovery, are needed. This includes capping or phasing down the use of plastics and implementing a plastics tax. With these measures, we can protect our water quality, maintain the health of our environment, and ensure the well-being of marine ecosystems and all those who depend on them.

Reducing the use of single-use plastics

Water pollution is a pressing issue in Australia, the world's driest inhabited continent, where less than three per cent of the Earth's total supply of water is fresh water.

One way to reduce water pollution is to cut down on the use of single-use plastics. Australians, organisations and businesses are already demonstrating their commitment to finding creative and meaningful solutions to this issue. For example, WWF-Australia has shown how we can reduce our reliance on single-use plastics, and reuse and recycle the plastics already in circulation.

Single-use plastics are a major contributor to water pollution, as they are often not disposed of properly and can end up in our waterways. By reducing our use of single-use plastics, we can help to protect our water quality and maintain the health of our environment and our own quality of life.

One way to reduce single-use plastic consumption is to increase the number of water refill stations. By encouraging people to bring their own bottles to major events and providing refill options, we can significantly reduce the need for plastic bottles. For instance, by providing refill options at 70 major events, We-Refill reduced the need for 454,324 plastic bottles.

Another way to reduce single-use plastic consumption is to bring your own reusable bags when shopping. This helps to cut down on the number of plastic bags that are used once and then discarded.

Reducing the use of fertilisers and chemicals

To prevent this, it's important to manage water quality by understanding the current and desired uses of particular waterways. This means knowing how water is being used and ensuring that any use of water does not lead to pollution. For example, the Department of the Environment, Tourism, Science and Innovation in Queensland licenses discharges of treated sewage and industrial wastewater, and protects water quality under the Environmental Protection (Water and Wetland Biodiversity) Policy 2019.

In addition, individuals can help reduce water pollution by being mindful of their own water use and by supporting organisations that are committed to finding solutions to water pollution, such as WWF-Australia.

Reducing the use of industrial wastewater

Water pollution is a pressing issue in Australia, the world's driest inhabited continent. Industrial wastewater is just one source of water pollution, alongside agriculture, forestry, new developments and mining activities.

To reduce the use of industrial wastewater, it is important to understand the current and desired uses of particular waterways. Any use of water has the potential to pollute. For example, surface water run-off after rain can carry soil, fertilisers and chemicals into creeks and rivers, causing siltation, excessive plant growth and the death of aquatic plants and animals.

In Queensland, the Department of the Environment, Tourism, Science and Innovation manages water quality by licensing discharges of treated sewage and industrial wastewater. They protect water quality under the Environmental Protection (Water and Wetland Biodiversity) Policy 2019.

WaterNSW, a State-Owned Corporation established under the Water NSW Act 2014, operates the state's rivers and water supply systems. They supply two-thirds of the water used in NSW and own and operate the largest surface and groundwater monitoring network in the southern hemisphere.

By understanding and managing water quality, and by regulating and monitoring water use, we can work towards reducing the use of industrial wastewater and protecting our precious water resources.

Reducing the use of treated sewage

Water pollution in Australia can be reduced by limiting the use of treated sewage. Sewage treatment plants are not capable of treating all waste, and some pass through the system untreated. For example, feminine hygiene products that are flushed down the toilet can block screens at treatment plants.

To reduce the use of treated sewage, individuals can be mindful of what they flush down the toilet or pour down the drain. Feminine hygiene products, for instance, should be disposed of in household rubbish rather than flushed.

Additionally, individuals can reduce their water usage, as less water used means less wastewater to be treated. This can be achieved through simple actions such as turning off the tap while brushing teeth or washing dishes, fixing leaky faucets, and using water-efficient appliances.

Furthermore, water treatment systems can be improved to increase their capacity to treat sewage effectively. This can include implementing advanced treatment processes such as activated sludge processes and organics removal, which are already being adopted by many new plants in Australia.

By combining individual efforts to reduce water usage and properly dispose of waste with improved treatment processes, Australia can significantly reduce the use of treated sewage and, consequently, water pollution.
