Fix dripping faucets.
How much water is used in an average home:
Each of us uses about 150 gallons of water each day - just indoors!
Leaks of one drop per second wastes more than 6 gallons of water a day - that's 2,642 gallons of water a year.
The bathroom accounts for 65% of water used inside the home.
Toilet that runs on after flushing can leak at the rate of 5-10 gallons per hour, that's 52,840 to 105,680 gallons per year - enough to fill 1 to 2 large in ground swimming pools.
