The drip, drip, drip of a leaky faucet is more than an annoyance in the night. Leaking faucets are significant water wasters. A single drop of water measures about .33 ml. That's not much, but it's the cumulative effect that counts. According to this government website, a single home with one leaking faucet dripping at a rate of 20 drops per minute will drain two gallons of water per day and 925 gallons per year. That's a lot more than I expected. Use their calculator to see how much water you may be wasting, then fix those leaky faucets to conserve water.
