Water Conservation
Let it flow only when necessary. Turn off the water while you're brushing your teeth or shaving. Sounds basic, we know, but at ordinary household pressure, a running faucet can pour out 6 gallons of water in 3 minutes.
Same goes for washing the dishes. Use a basin when hand washing dishes. Wash all of the dishes and then rinse them all together.
Pass on the pre-rinse. Using your dishwashing machine when it's full can be more efficient than washing by hand, but pre-rinsing dilutes the savings. Instead, wipe dishes with a wet sponge before they go in the dishwasher.
Compost, not garbage disposal. Your kitchen sink garbage grinder requires lots of water to operate properly. Put all vegetable-based food scraps in a compost pile instead. Learn all about compost here.
Keep cool. Refrigerate a pitcher of water for cool drinks rather than letting the faucet flow until it gets cool.
Shorten your shower. The average shower lasts 8.2 minutes and the average showerhead dispenses 2.5 gallons per minute- that's about 20 gallons per shower.
Re-use and Recycle. Put a bucket in your shower to catch water while you wait for it to warm up. Use the bucket of water for houseplants or in your garden.
Bigger Bonus
Ready to make more dramatic cuts in your water use- and utility bill?
These steps will really stem the tide.
Audit your usage. If you get water from the public system, check your bill for the total water used and figure out daily use by dividing total water used by the number of days in the billing cycle. (An will help you convert from cubic meters, cubic feet, or liters to gallons.) If you draw water from a well, you'll need to check your water meter at 24 hour intervals to get your daily household water use. Do this for several days so you can get an average.
Look for leaks. Read your water meter before and after a two-hour period during which no water is used. If the meter does not read exactly the same, start searching for the leak. It's worth the effort: A faucet dripping just once per second wastes 2,700 gallons per year- the equivalent of 135 showers.
Test the toilet. Take the time to check your toilet for leaks, where they are common and not always obvious. Get dye specifically for this purpose at a hardware store- if there is a leak, color will appear in the bowl 30 minutes after you put dye in the tank. Toilets leak 1 gallon of water every 24 minutes, or 60 gallons per day.
Update the fixtures. federal legislation passed in 1992 raised efficiency standards on faucets, toilets, and showerheads. Look for low-flow toilets, faucets and showerheads, which use half (or even less) of the water needed to operate models manufactured before 1992. Dual flush toilets offer you the option of a half flush (no solids) or a full flush (solids).
Replace appliances. The EPA's labeling programs make it easy for you to identify efficient products when buying dish and clothes washing machines. The EnergyStar label has been used for years. New for 2007 is the Watersense label, for which the EPA has established even greater efficiency criteria. Water use in laundry machines is identified by the Water Factor or "WF", a measure of water used per cycle. The lower the WF rating, the higher the efficiency. New front-loading washing machines use about 40 percent less water than top-loading machines.
Save the Rain. Attach a rain barrel to your downspout to gather water to use in your garden. Go one step further and direct rainwater into a cistern for indoor use. You'll need to check building codes and at least consult with an engineer experienced with such systems. But what a difference you'll make.
