Water Conservation in the Home
Here are 25 ways to conserve water in the home and yard.
A small drip from a worn faucet washer can waste 20 gallons of water per day. Larger leaks can waste hundreds of gallons.
2. Don’t use the toilet as an ashtray or wastebasket
Every time you flush a cigarette butt, facial tissue or other small bit of trash, five to seven gallons of water is wasted.
3. Check your toilets for leaks
Put a little food coloring in your toilet tank. If, without flushing, the color begins to appear in the bowl within 30 minutes, you have a leak that should be repaired immediately. Most replacement parts are inexpensive and easy to install.
4. Use your water meter to check for hidden water leaks
Read the house water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.
5. Install water-saving shower heads and low-flow faucet aerators
Inexpensive water-saving low-flow shower heads or restrictors are easy for the homeowner to install. Also, long, hot showers can use five to ten gallons every unneeded minute. Limit your showers to the time it takes to soap up, wash down and rinse off. “Low-flow” means it uses less than 2.5 gallons per minute.
You can easily install a ShowerStart showerhead, or add a ShowerStart converter to existing showerheads, which automatically pauses a running shower once it gets warm. Also, all household faucets should be fit with aerators. This single best home water conservation method is also the cheapest!
6. Put plastic bottles or float booster in your toilet tank
To cut down on water waste, put an inch or two of sand or pebbles inside each of two plastic bottles to weigh them down. Fill the bottles with water, screw the lids on and put them in your toilet tank. Do it safely away from the operating mechanisms. You can also buy an inexpensive tank bank or float booster. This may save ten or more gallons of water per day.
Be sure at least 3 gallons of water remain in the tank so it will flush properly. If there is not enough water to get a proper flush, users will hold the lever down too long or do multiple flushes to get rid of waste. Two flushings at 1.4 gallons is worse than a single 2.0 gallon flush. A better suggestion would be to buy an adjustable toilet flapper that allow for adjustment of their per flush use. Then the user can adjust the flush rate to the minimum per flush setting that achieves a single good flush each time.
For new installations, consider buying “low flush” toilets, which use 1 to 2 gallons per flush instead of the usual 3 to 5 gallons.
Replacing an 18 liter per flush toilet with an ultra-low volume (ULV) 6 liter flush model represents a 70% savings in water flushed and will cut indoor water use by about 30%.
7. Insulate your water pipes
It’s easy and inexpensive to insulate your water pipes with pre-slit foam pipe insulation. You’ll get hot water faster plus avoid wasting water while it heats up.
8. Take shorter showers
One way to cut down on water use is to turn off the shower after soaping up, then turn it back on to rinse. A four-minute shower uses approximately 20 to 40 gallons of water.
9. Turn off the water after you wet your toothbrush
There is no need to keep the water running while brushing your teeth. Just wet your brush and fill a glass for mouth rinsing.
10. Rinse your razor in the sink
Fill the sink with a few inches of warm water. This will rinse your razor just as well as running water, with far less waste of water.
11. Use your dishwasher and clothes washer for only full loads
Automatic dishwashers and clothes washers should be fully loaded for optimum water conservation. Most makers of dishwashing soap recomend not pre-rinsing dishes which is a big water savings.
With clothes washers, avoid the permanent press cycle, which uses an added 20 liters (5 gallons) for the extra rinse. For partial loads, adjust water levels to match the size of the load. Replace old clothes washers. New Energy Star rated washers use 35 – 50% less water and 50% less energy per load. If you’re in the market for a new clothes washer, consider buying a water-saving frontload washer.
12. Minimize use of kitchen sink garbage disposal units
In-sink ‘garburators’ require lots of water to operate properly, and also add considerably to the volume of solids in a septic tank which can lead to maintenance problems. Start a compost pile as an alternate method of disposing food waste.
13. When washing dishes by hand, don’t leave the water running for rinsing
If your have a double-basin, fill one with soapy water and one with rinse water. If you have a single-basin sink, gather washed dishes in a dish rack and rinse them with a spray device or a panful of hot water. Dual-swivel aerators are available to make this easier. If using a dishwasher, there is usually no need to pre-rinse the dishes.
14. Don’t let the faucet run while you clean vegetables
Just rinse them in a stoppered sink or a pan of clean water. Use a dual-setting aerator.
15. Keep a bottle of drinking water in the fridge
Running tap water to cool it off for drinking water is wasteful. Store drinking water in the fridge in a safe drinking bottle.
Water Conservation in the Yard and Garden…
16. Plant drought-resistant lawns, shrubs and plants
If you are planting a new lawn, or overseeding an existing lawn, use drought-resistant grasses such as the new “Eco-Lawn”.
Many beautiful shrubs and plants thrive with far less watering than other species. Replace herbaceous perennial borders with native plants. Native plants will use less water and be more resistant to local plant diseases. Consider applying the principles of xeriscape for a low-maintenance, drought resistant yard.
Plant slopes with plants that will retain water and help reduce runoff.
Group plants according to their watering needs.
17. Put a layer of mulch around trees and plants
Mulch will slow evaporation of moisture while discouraging weed growth. Adding 2 – 4 inches of organic material such as compost or bark mulch will increase the ability of the soil to retain moisture. Press the mulch down around the dripline of each plant to form a slight depression which will prevent or minimize water runoff.
For information about different mulch materials and their best use, click here.
18. Don’t water the gutter
Position your sprinklers so water lands on the lawn or garden, not on paved areas. Also, avoid watering on windy days.
19. Water your lawn only when it needs it
A good way to see if your lawn needs watering is to step on the grass. If it springs back up when you move, it doesn’t need water. If it stays flat, the lawn is ready for watering. Letting the grass grow taller (to 3″) will also promote water retention in the soil.
Most lawns only need about 1″ of water each week. During dry spells, you can stop watering altogether and the lawn will go brown and dormant. Once cooler weather arrives, the morning dew and rainfall will bring the lawn back to its usual vigor. This may result in a brown summer lawn, but it saves a lot of water.
20. Deep-soak your lawn
When watering the lawn, do it long enough for the moisture to soak down to the roots where it will do the most good. A light sprinkling can evaporate quickly and tends to encourage shallow root systems. Put an empty tuna can on your lawn – when it’s full, you’ve watered about the right amount. Visit our natural lawn care page for more information.
21. Water during the early parts of the day; avoid watering when it’s windy
Early morning is generally better than dusk since it helps prevent the growth of fungus. Early watering, and late watering, also reduce water loss to evaporation. Watering early in the day is also the best defence against slugs and other garden pests. Try not to water when it’s windy – wind can blow sprinklers off target and speed evaporation.
22. Add organic matter and use efficient watering systems for shrubs, flower beds and lawns
Adding organic material to your soil will help increase its absorption and water retention. Areas which are already planted can be ‘top dressed’ with compost or organic matter.
You can greatly reduce the amount of water used for shrubs, beds and lawns by:
- the strategic placement of soaker hoses
- installing a rain barrel water catchment system
- installing a simple drip-irrigation system
Avoid over-watering plants and shrubs, as this can actually diminish plant health and cause yellowing of the leaves.
When hand watering, use a variable spray nozzle for targeted watering.
23. Don’t run the hose while washing your car
Clean the car using a pail of soapy water. Use the hose only for rinsing – this simple practice can save as much as 150 gallons when washing a car. Use a spray nozzle when rinsing for more efficient use of water. Better yet, use a waterless car washing system; there are several brands, such as EcoTouch, which are now on the market.
24. Use a broom, not a hose, to clean driveways and sidewalks
25. Check for leaks in pipes, hoses, faucets and couplings
Leaks outside the house may not seem as bad since they’re not as visible. But they can be just as wasteful as leaks indoors. Check frequently to keep them drip-free. Use hose washers at spigots and hose connections to eliminate leaks.
Water conservation comes naturally when everyone in the family is aware of its importance, and parents take the time to teach children some of the simple water-saving methods around the home which can make a big difference.
Water Conservation Summary
In 1990, 30 states in the US reported ‘water-stress’ conditions. In 2000, the number of states reporting water-stress rose to 40. In 2009, the number rose to 45. There is a worsening trend in water supply nationwide. Taking measures at home to conserve water not only saves you money, it also is of benefit to the greater community.Saving water at home does not require any significant cost outlay. Although there are water-saving appliances and water conservation systems such as rain barrels, drip irrigation and on-demand water heaters which are more expensive, the bulk of water saving methods can be achieved at little cost. For example, 75% of water used indoors is in the bathroom, and 25% of this is for the toilet. The average toilet uses 4 gallons per flush (gpf). You can invest in a ULF (ultra-low flush) toilet which will use only 2 gpf. But you can also install a simple tank bank, costing about $2, which will save .8 gpf. This saves 40% of what you would save with the ULF toilet. Using simple methods like tank banks, low-flow showerheads and faucet aerators you can retrofit your home for under$50.
By using water-saving features you can reduce your in-home water use by 35%. This means the average household, which uses 130,000 gallons per year, coulod save 44,00 gallons of water per year. On a daily basis, the average household, using 350 gallons per day, could save 125 gallons of water per day. The average individual, currently using 70 gallons per day, could save 25 gallons of water per day.When buying low-flow aerators, be sure to read the label for the actual ‘gpm’ (gallons per minute) rating. Often, the big box retailers promote “low-flow” which are rated at 2.5 gpm, which is at the top of the low-flow spectrum. This may be needed for the kitchen sink, but we find that a 1.5 gpm aerator works fine for the bathroom sink and most water outlets, delivering the same spray force in a comfortable, soft stream. Eartheasy’s online store carries a full range of low-flow aerators and showerheads.Finally, it should be noted that installing low-flow aerators, showerheads, tank banks and other water-saving devices usually is a very simple operation which can be done by the homeowner and does not even require the use of tools. Water conservation at home is one of the easiest measures to put in place, and saving water should become part of everday family practice.
A guide to Waterwise Gardening
The following “Seven Fundamentals of Low-Water Use” should improve your chances of creating a successful landscape.
Soil Improvement: Adding organic matter to the soil will help to retain water and provide needed plant nutrients. The depth to which this organic matter should be cultivated into soil depends on your design. Different plant types require different depths. Appropriate Use of Turfgrass: Lawns are our largest water user. Turf requires twice as much water as established drought tolerant plants. Smaller, rounded plots of lawn on level areas are easiest to water efficiently. Local WSU Cooperative Extension agents can assist in the selection of grass species and provide information on proper maintenance.
Efficient Irrigation: There are a variety of irrigation technologies to choose from: surface systems, subsurface drip systems, timed and untimed systems, and hand watering. Efficiency in an irrigation system is attained by keeping the system well maintained and applying water only as plants need it. Good soil preparation and proper plant selection can alleviate the need for irrigation altogether.
Use of mulches: Mulches reduce the amount of moisture that evaporates from bare ground. Mulches also help insulate plant roots during cold periods and deter weed growth. Organic mulches include wood chips, bark, straw, grass clippings, peat moss, and coarse sand. Mulches should be spread a few inches thick around plants and on any bare ground.
Selection of Low-Water Use Plants: Plants that thrive in the microclimate of the site should be selected, i.e. high and low temperatures, soil types, available sunlight, humidity and natural precipitation. Plants native to our region are “best choices”. Some plants from the Mediterranean climates also do well here. Keep in mind that some low-water use plants have specific needs such as shade or hydric soils. Not meeting these needs can cause increased watering. There are many good reference materials dealing with plant selection and low-water landscape design. A reputable garden nursery person can also be helpful.
Planning and Design: Evaluate existing conditions and assess your needs. What are your conservation goals? How much time can you realistically devote to a garden? Start with a notebook, collect images, visit garden nurseries and professional gardens. Remain flexible and don’t focus on details too quickly; use “bubble” diagrams. Reinforce your shape through a variety of plant layers. Plan on 3/4 of mature size when estimating plant quantities.
Appropriate Maintenance: Even drought resistant plants require additional watering until established (usually three to six months). Planting should be done semiannually, in fall and early spring, to take advantage of natural precipitation. Weeds require a great deal of water to compete with other plants. During the first growing season it is important to hand-weed to prevent damage to the soil. Correct pruning to remove dead and diseased growth and promote the plants natural shape may reduce the plant’s water demands.
Desert plant landscape is called Xeriscape. This is a great choice for San Diego County. We live in a semi-arrid desert so this is a logical choice for your home.
