Why is it important to treat sewage before disposing of it?

Here's why it is important to treat sewage before disposing of it:

• Public Health Protection: Untreated sewage contains pathogens that can cause diseases like cholera and typhoid, contaminating water sources and spreading illness.
• Environmental Protection: It prevents eutrophication in water bodies caused by organic matter and nutrients, which depletes oxygen and harms aquatic life.
• Odor Control: Treatment eliminates foul odors produced by decomposing sewage.
• Removal of Pollutants: It removes solid waste, chemicals, and heavy metals, preventing environmental accumulation and damage.
