A sewer is an underground system of pipes that carries waste, stormwater, or other liquid waste away from homes, buildings, or streets to be treated or disposed of. It helps prevent flooding, manage waste, and protect public health by directing waste to treatment facilities. Sewers can vary in size and design, ranging from small residential pipes to large city-wide systems.
