What is sewage water and what are the different types of sewage?

Sewage water is wastewater from people living in a community. It is the water released from households after use for various purposes like washing dishes, laundry, and flushing the toilet, thus the name wastewater. The used water moves from the houses through pipes installed during plumbing. The sewage water then moves into sewers, either constructed by the house owner, or into a sewer facility set up by the municipality.

Mostly, sewage water consists of grey water and black water. Grey water is the waste water from washing either from bathing, dishes or laundry. Black water is the waste water from toilets. It is characterized by debris such as paper wrappings, sanitary products, soap residues, and dirt due to the chemical composition of the various waste materials. Plus, sewage water has a foul smell.

There are two types of sewage: treated and untreated.

Treated sewage:

Treated sewage refers to wastewater or sewage which has passed through a treatment plant. Sewage goes through several stages in the treatment process ensuring that all harmful bacteria, pollutants and contaminants are eliminated. The stages of sewage treatment include pre-treatment, primary, secondary and tertiary sewage treatment. The last stage usually involves the use of UV light to ensure all bacteria and/or viruses are removed. After treatment, the water will usually pass into rivers or seas or be reused for irrigation and agricultural purposes.

Coming into contact with treated sewage is rare, but can arise if large flooding events affect sewage treatment plants or in very rare cases there is a pump or other equipment failure that results in wastewater spreading over land and potentially into property.

Untreated sewage:

Untreated sewage refers to wastewater which contains harmful waterborne pathogens and bacteria and which has not yet gone through a sewage treatment plant. Raw sewage originates from broken toilet pipes, overspills, industry leakages and heavy storms. It poses an extremely high risk to human and animal health and the longer it sits and stagnates a home or a business, the greater amount of bacteria it will contain.

Quite often, in the poorer areas of the world, sewage can get dumped anywhere and this is unfortunate as people have no access to proper treatment plants, therefore increasing health risks in those areas.
