Sewerage refers to the system of underground pipes, drains, and other infrastructure used for carrying wastewater, including sewage and stormwater, away from buildings and cities to treatment plants or bodies of water. It encompasses the entire infrastructure that is responsible for collecting, transporting, treating, and disposing of wastewater.
The purpose of sewerage is to prevent the contamination of the environment and to maintain public health and hygiene. It plays a vital role in urban planning and development, as it ensures the safe disposal of wastewater that is generated from various domestic, commercial, and industrial activities.
The sewerage system typically consists of a network of pipes, manholes, pumping stations, and treatment facilities. Wastewater from sinks, toilets, showers, and other sources is carried through gravity or pumps to larger sewer pipes, and eventually to wastewater treatment plants where contaminants are removed before the treated water is discharged back into the environment.
Sewerage infrastructure is designed to handle different types of wastewater, including both sanitary sewage and stormwater. In areas where both sanitary and storm sewers exist, they are usually separated to prevent overwhelming the system during heavy rain events.
Overall, sewerage is a crucial component of modern urban life, ensuring the proper and safe disposal of wastewater, protecting public health, and reducing the impact of human activities on the environment.
