Many people think that sewage is dirty water or smelly drains, but sewage is more than just an unpleasant mess. It is a biohazard and can harm people, animals and the environment. In Australia, sewage cleanup is a serious problem, but the good thing is that companies like Unit 444, with their skilled workers, play a key role in biohazard cleaning.
In this article, we shall learn in depth about sewage cleaning, is sewage a biohazard, how it spreads and if you fall into it, what you should do instantly.
Difference between Sewage and Bio-hazards
First of all, we will understand the difference between sewage and biohazards. Sewage is wastewater containing human waste, household chemicals and other contaminants from toilets, sinks and drains. This dirty water carries things like poop, urine, soap, leftover food and chemicals.
While sewage becomes a biohazard when it holds viruses, bacteria or parasites that can make people and animals severely sick through touching, breathing or drinking it.
For example, touching sewage water can give stomach bugs, skin rashes or infections. In simple words, sewage is the source and biohazards are the danger inside it.
Is Sewage a Biohazard?
Yes, sewage is a biohazard as it contains harmful viruses, bacteria and parasites. These germs cause severe diseases like liver issues, skin problems when touched. Our biohazard cleaners at Unit 444 treat the contamination completely; even small exposure can lead to illness.

Is Urine Considered a Biohazard?
Most healthy people’s urine has fewer germs compared to faeces, but it can still carry diseases if the person has an infection. Large amounts of urine release ammonia fumes, which can irritate the lungs and cause respiratory issues. So yes, Urine is considered a biohazard, particularly when mixed with sewage water.
Is Human Waste a Biohazard?
Yes, human waste and urine are biohazards. Poop can contain bacteria like E.coli and viruses like Hepatitis A. This is why toilets are built to flush waste into safe treatment plants. If this system fails, the waste becomes dangerous. Urine can carry germs, especially if the person is unwell.
Is Poop a Biohazard?
Yes, poop is one of the biggest biohazards in sewage. Human or animal waste is full of bacteria and parasites that can survive in water and soil for a long time. If people or pets touch it, they can get very sick. This is the reason Unit 444 cleaners wear full protective gear when handling faeces during sewage clean-ups.
Is Raw Sewage Considered Hazardous Waste?
Yes, raw sewage is a form of hazardous waste, and it is untreated and unsafe. In Australia, some strict laws and regulations must be followed regarding cleaning and companies must have a license, such as Unit 444 in Perth. Raw sewage can pollute rivers, harm sea life, and spread diseases across societies if raw sewage is not handled quickly.
Does sewage overflow cause illness?
Yes, sewage overflow can cause illness. Sewage-related illnesses include:
- Gastroenteritis – stomach pain, vomiting, diarrhea.
- Hepatitis A – liver infection.
- Skin infections – touching contaminated water.
