Believe it or not, the average water usage per person per day is 200 gallons.
Showering wet down, soap up, rinse off = 4 gallons
Brushing teeth wet brush, rinse briefly, = ½ gallon
Shaving, fill sink basin = 1 gallon
Washing hands fill sink basin = 1 gallon
Tub bath minimal water level = 10 to 12 gallons
Flushing toilet using a smaller tank = 4 to 6 gallons
Dish-washing- Washing and rinsing in the sink = 5 gallons
Automatic dishwasher short cycle = 7 gallons
Washing machine short cycle with minimal water level = 27 gallons
Outdoor watering average hose = 10 gallons per minute
Leaks - even a small drip can add up to 25 gallons per day.
The above gallon usage is calculated minimally. You can count on using quite a bit more if you leave the water running while brushing your teeth, shaving, washing the dishes, using old toilets that require more water, running the dishwasher and washing machines on longer cycles and filling the bath tub to the top. As you are aware, water is not cheap any more or limitless. Please use this natural resource wisely and save on your water bill
