1) Use Your Dishwasher
Contrary to popular belief, it takes more water to hand-wash dishes than it takes to wash them in the dishwasher.
2) Don't Pre-Rinse Dishes
Scrape food from plates, and let your dishwasher do the rest.
3) Only Run the Dishwasher When Full
You'll use the same amount of water whether you run a full load or a partial load.
4) Install a Faucet Aerator
It screws onto the bottom of your faucet to reduce water flow, without reducing water pressure. You can even get some that swivel to allow you to direct the water where you need it. Note: If you have a newer faucet, it may already have one built-in.
5) Keep Drinking Water in the Fridge
Then, you won't waste water while you wait for the tap to get cold. Another option: Fill a cup with tap water, and drop in a couple ice cubes to chill it.
Heat Water on the Stove/ In the Microwave
Then, you won't waste water while you wait for the tap to get hot.
6) Install a Point-of-Use Hot Water Heater
If you regularly need hot water for pots, dishwashing and hot drinks, consider installing a point-of-use hot water heater (also known as an instant hot water system) under the kitchen sink. It’ll supply you with hot water as soon as you turn on the tap, and only costs a couple hundred dollars.
7) Don’t Use the Disposal
Compost food waste or throw it in the trash. Both are water-free options.
8) Switch to a Low-Flow Shower Head
Low-flow showerheads use 2.5 gallons per minute (gpm); older models use as much as 5.5 gpm. Make the switch and you'll reduce your water bill by 25-60 percent (US Department of Energy).
9) Take Shorter Showers
Aim for a five-minute shower. With a low-flow showerhead you'll use 12.5 gallons of water or less. Compare that to 37.5 gallons for a 15-minute shower, and the savings is pretty easy to see.
10) Shower Instead of Taking Baths
According to the Environmental Protection Agency, it takes 35 gallons of water to fill the average bathtub. Switch to a five-minute shower with a low-flow showerhead, and you'll save 22.5 gallons each time you scrub up!
11) Repair Faucet Leaks
A leaky faucet can waste 1000-2000 gallons of water a year (National Sanitation Foundation).
12) Install a Faucet Aerator
It screws onto the bottom of your faucet to reduce water flow, without reducing water pressure. Note: If you have a newer faucet, it may already have one built-in.
13) Turn the Water Off While You Brush/ Shave
Less flow time equals less water used.
14)Check Toilets for Leaks
According the National Sanitation Foundation, a leaky toilet can waste as much as 500 gallons of water each day! Place a dye tablet (free at home improvement stores) in the toilet tank, and watch to see if the dye seeps into the bowl. If it does, you have a leak that needs to be addressed.
15)Replace Your Toilet Flapper Once a Year
Toilet flappers break down quickly, and should be replaced once a year--even if they say they're good for longer. A couple dollars spent on a replacement flapper will save you much more on your water bill.
16) Install an Adjustable Flapper
Several manufacturers now offer flappers that you can adjust to your desired flush volume. According to Niagara Conservation, an adjustable flapper can save up to three gallons per flush.
17) Install a Fill Cycle Diverter
Save another 1/2 gallon per flush by installing a fill cycle diverter in each of your toilets. This simple add-on costs less than a dollar, and is designed to divert overflow water back to the tank during the fill cycle.
18) Place a Bottle in the Toilet Tank
Fill a bottle with water, and place it in the toilet tank. It'll displace water, and cause the tank to fill with less water. Just how much water will this save? An amount equal to the size of the bottle that you placed in the tank. A 20 oz. bottle, for example, will save 20 oz. of water per flush.
19) Switch to a Low-Flow Toilet
When it's time to replace your toilet, replace it with a low-flow model that uses 1.6 gallons per flush, compared to a traditional toilet, which use 3.6 gallons.
20) Only Wash Full Loads
You’ll save water, and wear and tear on your machine.
Wear Clothes More than Once
Pants and outwear usually don't get very dirty. Wear them twice before washing, and you'll cut down on your water use and your housework. Now that's hard to argue with!
21) Upgrade to a High-Efficiency Washer
A high-efficiency washer can be as much as three times as efficient as a regular washer. (US Department of Energy). Upgrade when your current washer dies, and enjoy the savings.
AROUND THE HOUSE
22) Utilize Greywater
Save unused drinking water, capture water while you're waiting for the shower to heat up and hang on to your cooking water--then use it to water your plants.
23) Insulate Pipes
Cover your hot water pipes with foam insulation to prevent heat loss. The pay off: hot water faster and less water waste.
Place Your Hot Water Heater Close to Where You Use It
The shorter the distance the water has to travel, the faster you'll have hot water.
24 )Install a Hot Water Recirculation System
This relatively inexpensive system (just a couple hundred dollars) uses a pump to pull hot water from the hot water heater faster, and returns cool water from the pipes to the water heater for reheating.
25) Install a Tankless Hot Water Heater
When it’s time to replace your hot water heater, consider upgrading to a tankless unit (also known as an on-demand water heater), it heats water faster and only when you need it--a water savings and an energy savings.
26) Collect Rain Water for Plants
Attach rain barrels to the end of your gutter drain spouts to collect rainwater. Then, use it to water your plants and to wash your car.
27) Use a Wading Pool Instead of a Sprinkler
Fill a wading pool for your kids, instead of letting them play in the sprinkler. They can splash around for hours without the continuous flow of water.
28) Choose Drought-Resistant Plants
Then, let the rain handle all of the watering.
29) Mulch Your Garden
Mulch reduces evaporation, ensuring that your plants get the full benefit of rainwater and your waterings.
30) Sweep Sidewalks Off Instead of Spraying
A little sweeping action can save a lot of water--as much as 80 gallons a year, according to wateruseitwisely.com.
31) Wash Your Car Less Often
Eartheasy.com, says it takes up to 100 gallons of water to wash a car. The Environmental Protection Agency says it can take over 500 gallons. Either way, that's a lot of water to devote to car washing.
32) Take Your Car to A Car Wash
You'll eliminate 100 gallons (or more) of water from your water bill each time you take your car to a car wash, and if you choose a facility that recycles water, you'll be saving the environment too.
