"Black Water" is a term used to describe wastewater that contains human waste, typically from toilets. It is considered hazardous due to the presence of pathogens and harmful bacteria. Proper treatment and disposal of black water are essential to prevent environmental contamination and protect public health. In many regions, black water is treated at sewage treatment plants, where it undergoes processes like filtration and disinfection. This ensures that harmful substances are removed before the water is released back into the environment or reused. Effective management of black water is crucial for maintaining clean water sources and supporting sustainable sanitation practices.
