The terms “sewer” and “sewerage” are related, but they refer to different aspects of wastewater management:
A sewer is a physical infrastructure or system of underground pipes, conduits, and manholes used to collect and transport wastewater, including sewage and sometimes stormwater runoff, from homes, businesses, and industries to wastewater treatment facilities or disposal points.
The primary function of a sewer is to convey wastewater, such as sewage, away from populated areas to prevent waterborne diseases, water pollution, and potential environmental hazards.
Sewerage refers to the entire system or network of sewers, along with associated components and facilities, that work together to manage and transport wastewater from its source to a treatment plant or disposal point.
It encompasses the entire infrastructure required for collecting, conveying, treating, and disposing of wastewater, including sewers, manholes, lift stations, wastewater treatment plants, and outfall points.
In summary, a sewer is a specific component of the sewerage system, referring to the physical pipes and conduits that transport wastewater. Sewerage, on the other hand, is a broader term that refers to the entire wastewater management system, including the sewers themselves and all the facilities and structures involved in managing and treating wastewater. While a sewer is part of sewerage, sewerage includes all the elements needed to handle wastewater effectively and ensure public health and environmental protection.
