45+ Ways to Conserve Water in the Home and Yard

Don’t use the toilet as an ashtray or wastebasket
How can we conserve water? Every time you flush a cigarette butt, facial tissue, or other small bit of trash, you’re wasting gallons of water. Put them in the garbage, or better yet, recycle.

Put plastic bottles or a 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. Fill the bottles with water, screw the lids on, and put them in your toilet tank, safely away from the operating mechanisms. Or, buy an inexpensive tank bank or float booster. This may save ten or more gallons of water per day. Be sure at least three 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 flushes at 1.4 gallons are worse than a single 2 gallon flush.

Buy an adjustable toilet flapper
Installing an adjustable toilet flapper will allow for adjustment of each per flush use; the user can adjust the flush rate to the minimum per flush setting that achieves a single good flush each time.

Install low or dual flush models
Federal regulations state that new toilets must use no more than 1.6 gallons per flush. Replacing an old toilet with an ultra-low volume (ULV) 1.6 gallon flush model represents a 70% savings in water and will cut indoor water use by about 30%. Alternatively, consider purchasing a dual flush toilet or installing dual flush converter that turns a standard toilet into a dual flush toilet, saving an average family 15,000 gallons of water each year. More water can be used when it’s needed, but for most flushes you’ll be using 70% less, adding up to some significant water savings.

Install composting toilets
Composting toilets are the most effective way to cut water waste from your bathroom since they require no water at all! Better still, they keep all the nutrients and pollutants out of waterways and make them available for use in non-food landscapes. Check codes in your area to be sure they’re legal before installing one. Read our article about composting toilets to find out if they’re right for you.

Use Clothes washer for only full loads
No list of water conservation tips would be complete without considering the laundry room. With clothes washers, avoid the permanent press cycle, which uses an added 5 gallons (20 liters) for the extra rinse. For partial loads, adjust water levels to match the size of the load.

Consider a high efficiency washing machine
The most efficient washing machines use as little as seven gallons per load, compared to a whopping 54 for a traditional washer. A high efficiency (HE) washer should easily pay for itself over its lifetime in water and energy savings. 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, read our article about water-saving frontload washers.

Install water-saving showerheads, timers, and low-flow faucet aerators
When considering ways to save water at home, inexpensive, water-saving, low-flow showerheads or restrictors are easy for the homeowner to install. Long showers can use five to ten gallons every unneeded minute. “Low-flow” means it uses less than 2.5 gallons per minute. You can easily install a ShowerStart, which automatically pauses a running shower once it gets warm.

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. You can also install a simple shower timer, available from your local water utility or hardware store.

Fit household faucets with Aerators
This easy and effective water saving tip is also the cheapest! A simple low-flow aerator saves water in the bathroom.

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.

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. Water conservation techniques like this are simple to implement.

Minimize kitchen sink garbage disposal
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.

Opt for the dishwasher over hand washing
It may seem counterintuitive, but it turns out washing dishes by hand uses a lot more water than running the dishwasher, even more so if you have a water-conserving model. The EPA estimates an efficient dishwasher uses half as much water, saving close to 5,000 gallons each year.

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 pan full 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.

Don’t let the faucet run while cleaning vegetables
Just rinse them in a stoppered sink or a pan of clean water. This is one of many water conservation strategies.

Keep a bottle of drinking water in the fridge
Looking for more steps to conserve water? Running tap water to cool it off for drinking water is wasteful. Store drinking water in the fridge in a safe drinking bottle. If you are filling water bottles to bring along on outdoor hikes, consider buying a personal water filter, which enables users to drink water safely from rivers or lakes or any available body of water.

Check faucets and pipes for leaks
A small drip from a worn faucet washer can waste 20 gallons of water per day. Larger leaks can waste hundreds of gallons. Some faucet leaks are easily spotted, but others take a little more effort to locate. Dry sinks and tubs thoroughly and allow to sit for an hour. If you notice wetness, you’ve found a leak. To find leaks from faucet handles, dry the area around them before running water. You’ll see water collecting next to them if there’s a leak.

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.

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.

Insulate 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.

Recycle water
Collect the cold water you run before it’s hot enough to shower and use it to water plants or flush the toilet (known as a bucket flush). Rinse water from dishes and food preparation can be collected and used to soak other dishes.

Eat less water-intensive foods
Our diets account for roughly half of all the water we use. All food has a water footprint, but some are much larger than others. Eating less beef, one of the most water-intensive foods, is a smart place to start. Shifting away from animal products to a plant-based diet can shrink your water footprint significantly.

Buy less
Consumer products are an often-overlooked source of water use, accounting for up to a third of most people’s water footprint. Buying less of everything—from clothing to electronics to household goods—can dramatically decrease your water footprint.

Maintain irrigation systems
Water conservation practices include where we water. If you use an irrigation system, check that it’s operating correctly toward the beginning and end of each season. Clear any visible clogs, and adjust the settings according to the needs of your plants and the time of year. Plants will need less water in cooler weather and more in hotter weather, and correct settings will not only save water but ensure that plants are getting the right amounts. Also be sure the timer waters in the morning to reduce loss to evaporation and prevent moisture from staying on plants overnight.

Water during the early parts of the day; Avoid watering when it is 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. An automated watering system with a built-in moisture sensor can help ensure you’re only watering when necessary and at the most efficient time of day. If you’re using a timer, consider adding a rain or moisture sensor to avoid watering unnecessarily.

Add organic matter to your farden beds
Adding organic material to your soil will help increase its absorption and water retention. Areas that are already planted can be ‘top dressed’ with compost or organic matter every year. Turn a healthy dose of compost into new garden beds when preparing the soil for planting.

Harvest rainwater for watering vegetable beds
Use rain barrels or a catchment system to capture valuable rainwater from your roof. Plants prefer untreated water, so your garden will be healthier while you cut your water bill.

Use a soil moisture meter
Avoid over- or under-watering your garden with a simple-to-use soil moisture meter. The meter quickly lets you know whether the soil is dry, so you only need to water when the plant actually needs it.

Control weeds to reduce competition for water
Weeds use water, too! If you don’t weed, the garden invaders will take up water meant for your plants. A good layer of mulch around your plants not only conserves soil moisture but helps keep weeds under control.

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 “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.

Mulch 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 drip line of each plant to form a slight depression, which will prevent or minimize water runoff.
Learn more about different mulch materials and their best use.

Position sprinklers carefully
If you have to use sprinklers, position them so water lands on the lawn or garden, not on paved areas. Also, avoid watering on windy days.

Water lawns rarely
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. You can also replace thirsty Kentucky bluegrass lawns with Eco-Lawn, a grass seed mix that lowers your lawn’s water needs by over 85%.

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. Most lawns want about an inch of water per week, so note how much rain fell and add water accordingly. Visit our natural lawn care page for more information.

Use efficient watering systems
You can greatly reduce the amount of water used for shrubs, beds, and lawns by strategically placing soaker hoses installing a rain barrel water catchment system;
or installing a simple drip-irrigation system. For trees and woody shrubs, consider deep watering with slow-delivery irrigation like tree-ring soaker hose. Be sure to avoid over-watering plants and shrubs, since this can diminish plant health and cause yellowing of the leaves. When hand watering, use a variable spray nozzle for targeted watering.

Plant in ‘hydro-zones’
Grouping plants with similar water needs means you won’t be wasting water on plants that don’t need it. Keep your water-wise and xeriscaped plants together, and do likewise with thirstier plants. Water only certain zones regularly, while watering drought-tolerant plantings less frequently.

Plant trees for shade
In addition to making your house cooler and storing carbon, adding shade trees can lessen the need for watering. By protecting plants and soil from the afternoon sun, shade trees help conserve water.
