In construction, a sewer refers to an underground pipe system designed to carry wastewater and sewage away from buildings and homes to a treatment facility or disposal site. Sewers are a crucial component of urban infrastructure, providing a sanitary and efficient means of removing waste and preventing contamination of the environment.
The sewer system typically consists of a network of pipes that collect wastewater from toilets, sinks, showers, and other plumbing fixtures within buildings. These pipes are connected to larger sewer mains, which transport the wastewater to a treatment plant or septic system.
