Sanitary sewage refers to wastewater that comes from households and commercial buildings. This type of sewage includes water from sinks, toilets, showers, and washing machines, containing organic matter, food waste, and human waste. It is typically collected through a network of pipes and transported to treatment facilities. At treatment plants, sanitary sewage undergoes various processes to remove harmful substances and pollutants. The goal is to clean the water so it can be safely released into the environment or reused. Proper treatment is essential to protect public health and maintain clean water sources.
