Sewage discharge is a major cause of water pollution, which can have a devastating impact on aquatic ecosystems and human health. Sewage spills and infrastructure failures can release billions of gallons of under-treated sewage into surface waters every year, causing a significant decline in water quality. Sewage contains harmful bacteria, viruses, and parasites, as well as excess nutrients, which can fuel harmful algal blooms and put human health at risk. Even properly treated sewage can contain microscopic plastic fibres, which can make their way into marine ecology systems.

What You'll Learn
- Sewage discharge leads to a significant decline in water quality
- Sewage spills and infrastructure failures release under-treated sewage into surface waters
- Sewage contains bacteria, viruses and parasites that make people sick
- Sewage can cause diseases to spread, such as e-coli, diarrhoea and hepatitis A
- Sewage pollutes waterways with excess nutrients that fuel harmful algal blooms
Sewage discharge leads to a significant decline in water quality
Even properly treated sewage can cause problems. Researchers have found that microscopic plastic fibres, released when certain clothes are washed, can make it through wastewater treatment plants and into marine ecology systems. Sewage discharges also pollute waterways with excess nutrients, which fuel harmful algal blooms that put human health at risk.
Sewage can contain bacteria, viruses and parasites that can make people sick with gastrointestinal symptoms, rashes, skin and eye infections, and flu-like symptoms. This can be particularly harmful to vulnerable groups such as young children, the elderly, and those with compromised immune systems.
The decline in water quality caused by sewage discharge can have far-reaching impacts on ecosystems and communities that rely on clean water sources for their health, livelihoods, and well-being. It is important to address the issue of sewage discharge to protect and preserve the quality of our water sources for current and future generations.

Sewage discharges pollute waterways with excess nutrients that wreak havoc on coastal ecosystems by fuelling harmful algal blooms that put human health at risk. Even properly treated sewage can have its problems. Researchers have found that microscopic plastic fibres, released when certain clothes are washed, can make it through wastewater treatment plants and into marine ecology systems.
Leaking or flooding can cause completely untreated sewage to enter rivers and other water sources, causing them to become polluted. In September, a large part of the River Trent was polluted by sewage in Staffordshire. Over 15,000 fish were killed, and it would have been worse if the sewage had reached a human water source. Contamination of water sources can cause diseases to spread, such as E. coli, diarrhoea and hepatitis A.

Sewage discharge leads to a significant decline in water quality. Pathogens in the waste not only harm aquatic ecosystems, but also make the water unsafe for human and animal use. Sewage spills and infrastructure failures release approximately 900 billion gallons of under-treated sewage into surface waters every year. Sewage can contain bacteria, viruses and parasites that make people sick with gastro-intestinal symptoms, rashes, skin and eye infections, flu-like symptoms, and worse.
Sewage discharges also pollute waterways with excess nutrients that wreak havoc on coastal ecosystems by fuelling harmful algal blooms that put human health at risk.

Frequently asked questions
Sewage can cause water pollution when it is leaked or flooded into rivers and other water sources. This can happen due to infrastructure failures.
Sewage in water can cause diseases to spread, such as e-coli, diarrhoea and hepatitis A. It can also cause gastrointestinal symptoms, rashes, skin and eye infections, and flu-like symptoms.
Sewage discharge leads to a significant decline in water quality, harming aquatic ecosystems and making the water unsafe for human and animal use.
Sewage discharges pollute waterways with excess nutrients, fuelling harmful algal blooms that put human health at risk.
Sewage pollution can come from leaking or flooding of untreated sewage, as well as from discharges of stormwater and under-treated sewage due to infrastructure failures.
