A series of underground pipes and manholes, pumping stations, as well as other appurtenances that ensure the passage and drainage of sewage or waste is called the sewer system. It is also referred to as a sanitary sewer system. Wastes and sewages are general creation following the activities for sustaining life. But, these wastes and sewages need to be drained properly, so that these do not mix up with water that can cause harm to health. The system is meant for protecting water and public health.
