According to ISO 6107-7: 1997, black water is “domestic wastewater without gray water with faecal solids” in urban water management . The wastewater from toilets is called black water . The terms black and gray water make it possible to name separate wastewater cycles in buildings that contain different types of pollution.

Various projects to test these separate Abwässersammelung inside buildings or on municipal level to them by new sanitation systems remanufacture .
