Install a Low-Flow Showerhead - Using less water in the shower means less energy to heat the water. Install a showerhead flowing at 2.5 gallons per minute (gpm) or less. (Learn here how to check the flow rate of your existing shower head and replace it with a low-flow one.) Save 350 lbs. of carbon dioxide and $150.
Take Showers Instead of Baths - A bathtub holds up to 50 gallons of water. A typical shower uses less than 20 gallons.
Put an Aerator on Bathroom Sink Faucets - An aerator adds air to the water as it comes out the faucet. The addition of air uses less water and the pressure feels stronger. An aerator screws onto the faucet where the water comes out. It takes less than a minute to screw on and you can do it by hand with no tools. Get an aerator that uses 1.0 gallons per minute. They cost as little as $6.
Fix Leaks - A dripping faucet can lose 20 gallons a day and a leaking toilet can lose 100 gallons. Check for Leaks.
Turn Off the Water - When brushing teeth, washing dishes or shaving, leaving the water running unnecessarily wastes precious water.
Replace Old Toilets - Replacing toilets installed before 1994 can save you more than $1,000 in water and sewer charges over the next 10 years. Toilets made after 1994 use 1.6 gallons per flush and older toilets use 3 1/2 to 7 gallons per flush.
Buy a Dual Flush Toilet - A dual flush toilet conserves water by allowing the user to flush liquids with .9 gallons. A regular 1.6 gallon flush is still used for solids. Australia mandated dual flush toilets in 1993 and since then many nations have followed, including Singapore, France, Italy and Germany.
Fill Your Dishwasher - Run your dishwasher only with a full load. Save 100 lbs. of carbon dioxide and $40 per year.
Don't Pre-rinse Dishes - Check to see if your dishwasher can clean dishes without pre-rinsing them. Most newer dishwashers don't require pre-rinsing.
Reuse Clean Household Water - Collect all the water that is wasted while waiting for the hot water to reach your faucet. Use this to water your houseplants or outdoor planters. Do the same with water that is used to boil eggs or steam vegetables.
Buy a Front Loading Clothes Washer - Replacing a conventional top-loading washer with a WashWise machine can save thousands of gallons of water a year. Plus, they are gentler on clothes, reduce drying time, and require less detergent.
Practice Natural Yard Care - Select plants suitable for the climate and soil conditions of the site. Mulch around plants to retain moisture and discourage weeds. Group together plants with similar water needs. Learn more about Natural Yard Care.
Water Efficiently - Much of the world gets by on 2.5 gallons of water per day. The average American uses 400 gallons per day, 30% of which is for outdoor uses and half for watering lawns. Adjust watering schedules to reflect changes in plant water need and weather conditions. Get rebates to improve the efficiency of an automatic irrigation system. Fine-tune your irrigation system for best performance. Choose water-efficient equipment.
Harvest Your Rainwater - Put a rain barrel on your downspouts and use this water for irrigation.
Use a Car Wash - Car washes are often more efficient than home washing and treat their water rather than letting it straight into the sewer system. But check to make sure that they clean and recycle the water. Better yet, try the waterless car wash
