One Covid-19 recommended hand wash could use 4 liters of water if the tap is left on, and 2 liters if the tap is turned off while lathering our hands? Older toilets can use 13 to19 liters or even up to 26 liters of water with one flush, while new toilets can only use up to 6 liters per flush, and there are high efficiency toilets that use up to 4.8 liters per flush. Eye opening numbers! Until we can all have a hand washing basin connected to our flush (we are working to make this possible), what are we willing to do?
