    Greywater is just a more specific type of wastewater. Greywater is any non-industrial water waste, such as from washing dishes or bathing. Wastewater, however, covers everything including highway drainage, industrial water waste, and sewage.

    Greywater is non-industrial wastewater generated from domestic processes such as dish washing, laundry and bathing. Greywater comprises 50-80% of residential wastewater. Greywater comprises wastewater generated from all of the house’s sanitation equipment except for the septic tank (water from toilets is blackwater, or sewage). Greywater is distinct from blackwater in the amount and composition of its chemical and biological contaminants (from feces or toxic chemicals).
