Why is water conservation important? That seems like a fair question. Doesn't the water we use circulate into and out of us, up through evaporation and down as rain, around the globe? That's what some teacher said when she taught me about the hydrologic cycle.
In areas where drinking water supply is abundant, you're probably only hearing about water conservation during a presentation about green living in general. But in other areas, where there is an existing or potential water shortage, folks may be much more aware of the idea of water efficiency. You can use your neighborhood association or homeowner association meeting to give information about current or potential shortages, and to inspire and inform about water conservation.
Here are the main points about why water conservation is relevant to your community:
Shortages again will lead to higher costs for pumping water to plants (large or small) where it is purified for human consumption. Longer transports of water from its source to the purification plant and its ultimate distribution system of course will be more expensive than shorter hauls.
Water conservation does sound a little dull, and even the newer term, water efficiency, sounds, well, efficient but not riveting.
So here are some ideas about what to do:
• Figure out exactly what those costs of treating drinking water and wastewater are, and then dramatize that for the "average household." You'll need some pretty graphics and a vivid imagination about challenging citizens to consider what else they could buy with the amount of money that they're being charged for the two types of treatment. Every year, is your family giving up one steak dinner, a cheeseburger a week, an iPod, or what?
• I don't know what's going to be really funny about water conservation, but somewhere a comedian in your town is waiting to bust loose. If Drippy the Drip or Wanda Water Waster can't make people laugh, you'll have to invent your own cartoon characters. Balloons coming out of their heads say clever things about water conservation.
Ask the kids too what is funny or exciting about saving water. They could surprise you with their clever ideas.
A more subtle way to think about water conservation is to think about water efficiency. If we can achieve a result with the minimum amount of water possible, that's water efficiency. No one is asking you not to accomplish what's needed, so you don't have to go around with dirty clothes. Just make a game of cleaning your clothes with the least possible amount of water.
For your community as a whole, if you treat and deliver your own water supply, here's how to increase water efficiency:
• Meter the water and charge users according to usage. Some rate structures reward use rather than water efficiency, so look at the financial incentives. If you're in a smaller town that has always charged a flat rate, this can be a tough political battle. But it's very fair to pay according to use, and to try to keep the system as small as possible by penalizing overuse.
• Identify where water is leaking throughout the processing and delivery system, using computer-assisted leak detection equipment, and repair those leaks.
• Pipe cleaning, lining, and repairs may be necessary at any stage along the water delivery system, but of course larger pipes (or larger leaks) should be higher priority repairs.
• Consider whether seasonal pricing might be an effective deterrent to watering plants with treated drinking water, or irrigating the lawn at high noon.
• Work with commercial users on an individual basis, beginning with the largest users first, to see how they can both save water and save money. Audit where water is now being used. Encourage them to investigate methods of using "graywater," such as water from washing dishes, for some purposes.
• If the large user is a public park or golf course, change your landscape over time so that less and less water is necessary. We know that's a hard sell for golf courses, but surely some measures are possible.
• Retrofit public buildings with low-water aerators on faucets, and replace flapper valves. If you have showers, low-flow showerheads should be a high priority. Model landscaping efficiency, and if you are in a city large enough to be able to do so, provide information to your citizens about low water usage plants.
• Coordinate with the folks who keep track of your zoning regulations to give disincentives for grass turf maintenance, rather than requiring lawn. Many attractive residential landscapes contain little to no turf grass, so at least make it possible for those who want a different look to have it.
• Consider reducing water pressure in parts of town where pressure is higher than needed. For instance, a residence typically doesn't need pressure more than 80 psi. This promotes water conservation by reducing spills and gushes when kids turn on the faucet too far, and so forth.
• Make it illegal to irrigate at peak times of the day. Typically outdoor usage drives peak water demand, so when you reduce outdoor usage through any method, you reduce the potential for needing to add more water treatment capacity. You can expand on this idea by making car washing, filling private swimming pools, and hosing off sidewalks illegal at certain times of day or week. And for more reasons than one, make sure private pools don't leak.
• Educate your citizens, through pamphlets, websites, or a short tip on each month's bill. Make sure teachers are presenting the reasons to be vigilant about water conservation. Below we're placing a few tips to get you started, but any environmentalists in your community can spout off a long list of things to do or not do. Just don't make it so forbidding it sounds like people can never have any fun.
• Repair leaky faucets. A steady but small drip might mount up to 20 gallons of water a day!
• Consider replacement of old washers, showerheads, toilets, and sinks that pre-date water conservation oriented appliances and fixtures. Keep in mind that in the average home, about three-fourths of the water is used in bathrooms.
• Do not leave the water running in any circumstances where it isn't necessary. Where you grew up, you might have learned to leave the water on all the time while you're brushing your teeth, washing the potatoes, or rinsing the hand-washed dishes. But you can change. It only takes 21-28 days to break a habit.
• Minimize lawn watering. When you must water, do so in the early morning, water enough to do some good, and try to choose a still day instead of a windy one. And definitely don't water your sidewalk. You can now purchase some attractive rain barrels, so consider catching the water running off your roof for later distribution onto your lawn.
• Choose low water requiring plants.
• Use the clothes washer and dishwasher only when full. And use your garbage disposal as little as possible.
• Reduce the length of your showers. Yes, it's possible. You probably don't need water therapy to survive, or even to relax. It actually takes a very short amount of time to cleanse yourself; the rest is meeting some other need.
• Cut down on frequent car washing, boat washing, and any other large use of water that's mostly for the sake of vanity.
• The really simple check for leaks in the home system is to check your water meter when you know you can do without water for a couple of hours, then don't run any water for that period of time. Then check to see if the meter has moved. If so, somewhere your system is leaking and not giving you any benefit.
