Water Conservation Tips
- Inside your house, bathroom facilities claim nearly 75 percent of the water used. If the toilet handle frequently sticks in the flush position letting water run constantly, replace or adjust it. Take shorter showers. Replace your showerhead with an ultra-low-flow version. Some units are available that allow you to cut off the flow without adjusting the water temperature knobs.
- Operate automatic dishwashers and clothes washers only when they are fully loaded. Set the water level for the size of load you are using.
- Store drinking water in the refrigerator.
- Don’t let the tap run while you are waiting for cool water to flow.
- Insulate your water pipes. You’ll get hot water faster and avoid wasting water while it heats up.
- Be aware of and follow all water conservation and water shortage rules in effect in your community. Don’t assume – even if you get your water from a private well – that you need not observe good water use rules. Every drop counts.
- Encourage your school system and local government to help develop and promote a water conservation ethic among children and adults.
- Try to do one thing each day that will result in saving water. Don’t worry if the savings are minimal. Every drop counts. You can make a difference.
- Fix leaky faucets and plumbing joints. You’ll save 20 gallons per day for every leak stopped.
- Don't water sidewalks or your driveway. Adjust your sprinkler so that water lands on your lawn or garden where it belongs – and only there.
- Turn off the water while brushing your teeth. You’ll save three gallons each day.
- If you have a pool, use a pool cover to cut down on evaporation. It will also keep your pool cleaner and reduce the need to add chemicals. Savings could be 1,000 gallons a month.
- Set lawn mower blades one notch higher. Longer grass means less evaporation and less watering.
- When taking your car to a car wash, be sure it's one of the many that recycles its wash water.
