Fresh water is in extremely short supply on earth. Did you know that only 1% of water on earth is ground water that used for drinking. Fresh drinkable water is continuously wasted by over watering lawns. A typical residential sprinkler system uses about 26,000 gallons a year and wastes about 7,800 gallons a year due to overwatering.
