Greywater is wastewater generated from domestic activities such as laundry, dishwashing, and bathing, which can be recycled on-site for uses such as landscape irrigation and constructed wetlands. This wastewater contains no fecal matter (human feces). Greywater differs from water from the toilets which is designated sewage or blackwater to indicate it contains human waste.
