What is agua negras?

Agua negras, or "black water" in English, refers to wastewater from toilets and other sources that contain fecal matter and other bodily waste. This type of wastewater is considered highly contaminated and can pose a risk to human health and the environment if not properly treated and disposed of. Agua negras typically requires extensive treatment before it can be safely discharged back into the environment or reused for non-potable purposes such as irrigation. The treatment process may involve physical, chemical, and biological methods to remove impurities and pathogens, as well as disinfection to kill remaining bacteria and viruses. Proper management of agua negras is important for protecting public health, minimizing water pollution, and conserving water resources.
