Turning off the tap while brushing your teeth in the morning and at bedtime can save up to 8 gallons of water per day, which equals 240 gallons per month… If a faucet is dripping at a rate of one drop per second, 2,700 gallons of water per year would be wasted. This all adds to the cost of water and sewer utilities; not to mention wasting a resource that is not infinite. (wecanbegreen.com)
