What are the causes of sewage?
Sewage water is wastewater from a community's residents. It is the water that is released from households after being used for various purposes such as dishwashing, laundry, and toilet flushing, hence the name wastewater. The used water is removed from the houses via pipes installed during the plumbing process. The sewage water then flows into sewers, which are either built by the house owner or set up by the municipality.
Grey water and black water make up the majority of sewage water. Grey water is the waste water from washing, whether it is from bathing, doing dishes, or doing laundry. Toilet waste is referred to as black water. Due to the chemical composition of the various waste materials, it is distinguished by debris such as paper wrappings, sanitary products, soap residues, and dirt. Furthermore, sewage water stinks.
The concern is that sewage pollution has resulted from overpopulation in urban areas without proper planning, posing a threat not only to the environment but also to human health. It also has an impact on biodiversity, aquatic life, and agriculture, and it contributes significantly to eutrophication and an increase in Biological Oxygen Demand (BOD).
Sewage water causes:
1. The use of toilets as garbage cans
Toilets are designated as fixtures for quelling nature's cries. Unfortunately, careless people have turned toilets into deposit banks for waste materials such as papers, sanitary products, and some even flush plastics. These waste materials are the root causes of sewage line blockages in the majority of buildings. Blockages cause the toilets served by that sewer to overflow.
These waste materials then clog the waterways further along the sewer lines. Plastics, for example, such as soap wrappers, clog rivers and prevent further flow due to stagnation. As a result, it is home to dangerous organisms and bacteria.The spread of the foul odor from the sewer also contributes to air pollution as a result of the blockages. Sewer treatment plants, in general, face a great deal of difficulty as a result of blockages and foreign material present in the wastewater, resulting in sewage pollution.
2. Fats used in cooking
There is a lot of fat and oil in kitchen products. Kitchen sinks are also used to wash dirty dishes. These materials accumulate quickly at the walls of the pipes, forming coverings that reduce the diameter of the pipe system that drains wastewater into the sewer.
Continued disposal of fats, oils, and grease in sinks results in complete clogging of the sewage system. This is even more dangerous than the toilet blockage. No amount of cleaning will result in the removal of the layered cover if there is a blockage. This will necessitate the installation of a new pipe system, which will be costly.
This also causes flooding in homes as well as pollution from sewage odors. When the pressure of wastewater is high in a clogged with fats pipe, the obvious result is pipe bursting, which can lead to a messy situation in homes.
3. Wastewater overcapacity
Sewers are designed to handle a specific amount of wastewater. Nonetheless, sewers overflow for a variety of reasons. For starters, there are contractors who, during the construction of a building, end up connecting the new building's sewage system to an existing sewer built for another residential building.This causes sewer overflow, which is hazardous to human health and can result in acute viral, bacterial, and parasitic diseases such as giardiasis, typhoid, gastroenteritis, and Hepatitis A.
Flooding is another factor that contributes to an increase in waste water. When there is a lot of rain, the water seeks a way out and seeps into sewers, mixing with the waste water, resulting in more wastewater in the sewer. If the sewer volume is small, the sewer system will most likely be unable to hold the increasing volume of water, resulting in sewer pollution.
5. Improper wastewater handling
It is a common practice among industries. Because industries use a lot of water, the majority of it is discharged as wastewater. As expected, industries should treat the same water and reintroduce it into industry machinery for reuse. However, most industries in areas with lax environmental policies discharge raw sewage into waterways without any treatment.
When this occurs, the people living downstream are the most affected by the effects of sewage pollution. Furthermore, aquatic life dies as a result of the release of harmful toxins that interfere with the normal activities of sea life. The release of ammonia, for example, is toxic to plants. They easily oxidize with the oxygen present in water, depriving aquatic life of oxygen.
