Okay..... how do they know how much of the water used is being used for
toilets and urinals. There are too m any variables, like the water used
per flush, whether it is a urinal or a toilet, automatic or manual,
cycle rate. Women pee in toilets and men generally use urinals, the
latter using much less water per flush. If the place has a kitchen it
will be using more water for cleaning and rinsing.
