Automatic sprinklers, OK, I understand the want for a nice green lawn. HOWEVER, do they have to be set to automatically come on? Last night it rained….HARD, yet this morning, as I walked down the road to get to work, I counted five businesses with their lawn sprinklers on..and many of the heads were pointed toward the street instead of the lawns or hitting the windows of the buildings and missing the lawn altogether. .
If you have a janitor, facilities director, whatever, can’t he or she turn the sprinklers on…manually? I wonder how much water was wasted.
Humm, leads me to… Check your faucets at home — do any of them drip? Well, maybe it’s just a small drip — how much water can a little drip waste? True, a single drip won’t waste much water. But think about each faucet in your home dripping a little bit all day long. What if every faucet in every home on your block … in your town … in your state also dripped? The drips would add up to a flood of water wasted down the drain.
There is no scientific definition of the volume of a faucet drip, but after measuring a number of kitchen and bathroom sink faucets, the volume seems to be between 1/5th and 1/3rd of a milliliter (mL). Drips from bathroom tubs come in a bit more, though, at about 1/2 mL. So, for our calculations below (numbers are rounded), we are going to use 1/4 mL as the volume of a faucet drip. So, by these drip estimates:
- One gallon: 15,140 drips
- One liter: 4,000 drips
But consider this, one home, with three faucets, dripping at five drips per minute =
21,600 drips per day
one gallon of water per day
that’s 10 baths per year
Five litres per day
520 US gallons per year
something to consider.
