Plants don’t need perfectly clean water; you can use household wastewater (called greywater) in your garden - with some precautions. Greywater is any lightly used water that has been left over from use in the home - from the shower, bath, sink, laundry. Water from the toilet is referred to as blackwater and should only ever enter the sewerage system. Household soaps and detergents are harmless to plants, but water containing bleach or disinfectant, dishwasher salt and stronger chemicals should be avoided.
