Potable water

Potable water is drinkable water.  It flows from faucets and showerheads and is used in dishwashers, all of which require clean water for sanitary purposes.  Potable water is also used to flush toilets and irrigate landscapes – both are functions that could easily use greywater (recycled water) without compromising efficiency.  Where feasible, greywater should be used for these functions.
