Sewerage System

Connected sewerage systems comprise a network of underground sewer pipes, pump stations, sewage treatment plants and sludge treatment facilities. They generally operate by gravity. As a result, sewage treatment plants are usually located at drainage catchment outlets so that they can capture all the sewage easily without the high cost required for pumping.
