Graywater Fact Sheet

Graywater is untreated wastewater from residential clothes washers, bathtubs, showers and bathroom sinks. It does not include wastewater from kitchen sinks, dishwashers and toilets – or laundry water soiled by diapers. Graywater can be reused for irrigating plants and may even add fertilizer if it carries nutrients such as phosphorus or nitrogen.
