Hint: Municipal wastewater which contains enormous amounts of organic matter is known as sewage. Before disposal, hence, sewage is treated in sewage treatment plants (STPs) by heterotrophic microbes to render it less polluting.
Complete Step-by-step answer:
Human waste needs to be carried away from the houses and even the residential regions for purposes of cleanliness and hygiene. A drainage system is specially built to carry out this semi-solid waste through pipes outside the houses. This drainage system is distinct from the water drainage system that drains additional water as this system takes out pure waste. This waste is known as sewage or simply wastewater as it is mostly liquid in nature. The wastewater from commercial, domestic, and industrial sources is carried by sewers. Waste matter is carried away in sewers or drains. Human waste is often toxic to several organisms and can be treated in various methods to remove its dangerous components. Sewer pipes are underground pipes in order to transport sewage from houses and commercial buildings (but not stormwater) to municipal sewerage for maximum transportation to processing facilities or final disposal. A house or any building cannot be built without sewer pipes. It is the basis of any structure. Sewage or municipal waste should not be directly passed into streams, rivers, and other water bodies because it does not contain only human excreta and other organic waste but a number of pathogenic microbes. It is made less pollution by passing it through Sewage Treatment Plants (STPs).
Therefore the correct answer is Option C.
Note: The word sewage originates from the French assewer which means to drain out water. Every household contains a drainage system. So that liquid waste is taken out of the home easily. This waste is known as sewage and is drained out through pipes that drain out into an underground structure termed sewer that is placed outside the house. Sewage contains organisms that can be harmful to humans.
