One-third of an acre-foot of water is delivered to an average home every year . Between 40 % to 50 % of that water is used inside the home for showers , laundry , cooking , cleaning , and other uses . The remaining 50 % to 60 % is used outdoors for landscapes and watering lawns . A small fraction of water used outside returns to the water cycle eventually . Of the water used inside the house , 95 % returns to the water cycle through the treatment system . Rainfall and snowmelt on roofs and pavement reaches storm sewers which flow directly to streams .
