What is the main constituent of raw sewage?
Raw sewage is wastewater that has not been treated. It comes from residential properties, like houses and apartments, as well as commercial buildings and industrial and agricultural processes. Essentially, it is the liquid waste that comes from houses and businesses. Not surprisingly, it can contain a wide variety of contaminants and present a health hazard if left untreated where humans or animals can come into contact with it. For example, raw sewage may overflow from a sanitary sewer after a period of very heavy rainfall. Raw sewage often contains urine and feces from toilet flushing as well as other types of human waste; it may also contain such things as toilet paper and wipes. Sometimes, tampons and other feminine sanitary products are found in it as well. In this case, it is often referred to as blackwater. However, toilet flushing isn’t the only thing responsible for the creation of raw sewage. It can also be a result of industrial-site drainage, discharge from sewage-treatment
