What is sewage in biology?

sewage. The waste water from domestic, commercial and industrial sources carried by sewers. Waste matter carried away in sewers or drains. Human waste, often toxic to many organisms which can be treated in a variety of ways to eliminate its dangerous components.

Primary treatment consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface. The settled and floating materials are removed and the remaining liquid may be discharged or subjected to secondary treatment.

What happens to poop in the sewer?
