A sewer line is a network of pipes that carries wastewater from toilets, showers, baths, and sinks to a septic tank or a municipal treatment plant.
The main function of a sewer line is to remove all the wastewater from homes so that it can be treated before being released back into the environment.
In most cases, the sewer lines are buried underground and they are usually connected to the main sewer line that runs through a city or town.
The main sewer line is then connected to a treatment plant where all the wastewater is treated before being released into rivers, lakes, or the ocean.
Most homes in the United States are connected to a municipal sewer system, but there are some homes that have their own septic tank.

In some cases, the water from the septic tank can be used to irrigate the yard or garden.
