graywater systems

Graywater is collected wastewater from domestic processes, such as bathing, washing dishes, or laundry, and reused for flushing toilets, watering landscapes, and irrigation. Graywater makes up three-quarters of domestic wastewater, and is different from “blackwater,” which is heavily polluted and has high levels of biological contaminants and toxic chemicals.
