Water Conservation at Home: Simple Ways to Save Water and Protect the Environment

Water conservation is one of the simplest ways households can reduce waste, lower utility costs, save energy, and reduce unnecessary demand on local water supplies.

Every day, we use water for drinking, cooking, bathing, laundry, cleaning, gardening, and maintaining our homes. Because water is available whenever we turn on the faucet, it is easy to overlook the treatment plants, pumps, reservoirs, pipes, energy, and natural resources required to deliver it.

Conserving water does not mean giving up normal comfort. It means reducing avoidable waste and using water more efficiently.

Why Is Water Conservation Important?

Most of Earth's water is saltwater, and much of the planet's freshwater is frozen or otherwise unavailable for direct use. The water available to communities, agriculture, businesses, and ecosystems therefore needs to be managed carefully.

Water Supports Everyday Life

Water is essential for drinking, food preparation, sanitation, agriculture, manufacturing, energy production, recreation, and natural ecosystems.

Water Treatment and Delivery Require Energy

Municipal water must be collected, treated, tested, pumped, stored, and distributed. Households then use additional energy whenever water is heated for showers, laundry, dishwashing, and cleaning.

Reducing hot-water use can therefore save both water and energy.

Conservation Can Lower Household Costs

Depending on your utility and household, using less water can reduce:

• Water charges
• Sewer charges
• Energy used to heat water
• Electricity required for private-well pumps
• Wear on some plumbing fixtures and appliances

Conservation Helps During Dry Periods

Water supplies vary by region and season. Reducing unnecessary demand can make communities more resilient during drought, high-demand summer periods, or supply restrictions.

Where Do Households Use the Most Water?

Water use differs considerably by household and climate. Nationally, indoor uses account for most household consumption, while outdoor irrigation is much more important in dry climates and during summer.

Common household uses include:

• Toilets
• Showers and baths
• Faucets
• Washing machines
• Dishwashers
• Landscape irrigation
• Pools
• Leaks

Rather than worrying equally about every use, identify where your particular household consumes or wastes the most water.

The Highest-Impact Ways to Save Water at Home

Find and Repair Household Leaks

Leaks are among the most preventable sources of household water waste.

Signs of a Possible Leak

• Your water bill rises without an obvious change in use.
• You hear water running when fixtures are off.
• A toilet refills periodically without being flushed.
• You find damp areas beneath sinks or near appliances.
• Your water meter changes when no water is intentionally being used.
• You notice stains, mold, or damaged surfaces near plumbing.

Check a Toilet for Leaks

Add a few drops of food coloring to the toilet tank and wait without flushing. If colored water appears in the bowl, the tank may be leaking through the flapper or another internal component.

Use Your Water Meter

1. Turn off faucets, appliances, irrigation, and other water-using equipment.
2. Record the meter reading.
3. Wait without using water.
4. Check the meter again.

If the meter changes, investigate further for a possible leak.

Water-Saving Tips for the Kitchen

• Run the dishwasher only when full.
• Avoid unnecessary pre-rinsing. Scrape dishes and follow your dishwasher manufacturer's guidance.
• Do not continuously run the faucet while hand-washing dishes.
• Wash produce in a bowl rather than under continuous running water.
• Defrost food in the refrigerator instead of under running water.
• Cook with only the water needed.
• Repair dripping kitchen faucets promptly.

Keep Drinking Water Ready

If you regularly run the faucet while waiting for the water to get colder, keep a covered pitcher in the refrigerator instead.

If you prefer filtered drinking water, preparing it in advance can offer the same convenience while reducing the temptation to let water run unnecessarily.

Water-Saving Tips for the Bathroom

Bathrooms account for a substantial share of indoor household water use.

• Take shorter showers.
• Turn off the faucet while brushing your teeth.
• Turn off running water while shaving.
• Repair running toilets.
• Choose WaterSense-labeled showerheads when replacing older units.
• Install efficient faucet aerators.
• Avoid unnecessary flushing.
• Capture shower warm-up water for suitable cleaning or plant use.

Water-Saving Tips for Laundry

• Wash full loads whenever practical.
• Match the water level to the load on machines with manual settings.
• Choose a high-efficiency washer when replacing an older appliance.
• Use cold water when appropriate to reduce energy consumption.
• Pretreat stains to reduce repeat washing.
• Inspect hoses and connections for leaks or deterioration.
• Use the shortest suitable cycle.

Water-Saving Tips for the Yard and Garden

Outdoor water conservation can yield particularly large savings in warm, dry regions.

• Check soil moisture before watering.
• Water when evaporation and wind are relatively low.
• Do not irrigate automatically when rain has already supplied enough moisture.
• Use mulch to reduce evaporation and weeds.
• Choose plants suited to the local climate.
• Group plants by water needs.
• Consider drip or micro-irrigation where appropriate.
• Repair broken sprinkler heads and leaking valves.
• Keep irrigation water on plants and soil, not on sidewalks and streets.
• Follow drought restrictions and local watering rules.

Consider Smart Irrigation Controls

Weather-based and soil-moisture irrigation controllers can adjust watering based on environmental conditions rather than relying on a fixed schedule.

The technology works best when the irrigation system itself is properly designed, maintained, and programmed.

Water Conservation for Lawns

Lawns can require significant supplemental water, particularly when grass varieties are poorly matched to the local climate.

• Reduce unnecessary lawn area.
• Use regionally appropriate grass where turf is desired.
• Replace difficult-to-water sections with suitable native or drought-tolerant plants.
• Allow grass to grow to an appropriate height for the species.
• Avoid watering immediately before rain.
• Use rain or soil-moisture sensors where useful.

Saving Water When Washing Cars, Cleaning Outdoors, and Maintaining Pools

Cars and Outdoor Cleaning

• Use a bucket for most vehicle washing and a hose only when needed.
• Use a hose nozzle with automatic shutoff.
• Consider commercial car washes that recycle water.
• Sweep patios, driveways, and sidewalks instead of hosing them down.
• Repair outdoor faucet and hose-connection leaks.

Pools

• Use a pool cover when practical.
• Check the pool, pump, and plumbing for leaks.
• Avoid overfilling.
• Reduce unnecessary splashing.
• Maintain water chemistry to reduce unnecessary draining.
• Turn off decorative water features when they are not needed.

Teaching Children to Save Water

Children can develop conservation habits early without making water use feel restrictive.

• Turn off the faucet while brushing teeth.
• Report dripping faucets and running toilets.
• Avoid unnecessary flushing.
• Help water plants efficiently.
• Use reusable drinking bottles.
• Discuss where local water comes from and why it matters.

Saving Water Also Saves Energy

The strongest connection between water and household energy is usually hot water.

Energy is required for:

• Showers
• Baths
• Dishwashing
• Laundry
• Cleaning

Ways to reduce both water and energy include:

• Taking shorter showers
• Using efficient showerheads
• Washing clothes in cold water when appropriate
• Running full dishwasher and laundry loads
• Repairing hot-water leaks quickly

Water Conservation and Household Plumbing

Using water efficiently can also reduce unnecessary strain on water heaters, pumps, plumbing systems, and septic systems.

Homes With Septic Systems

Large volumes of water entering a septic system over a short period can interfere with normal operation.

Helpful practices include:

• Spreading laundry loads across the week
• Repairing leaks promptly
• Avoiding several high-water-use activities at once
• Maintaining the system according to local guidance
• Keeping roof and surface drainage away from the drain field

Reusing Water Around the Home

Some relatively clean household water can be reused for appropriate non-drinking purposes.

Simple examples may include:

• Using shower warm-up water for cleaning or plants
• Using produce-rinse water on suitable plants
• Using aquarium water on ornamental plants
• Using collected rainwater for landscaping where permitted

Rainwater Harvesting

Rainwater harvesting collects rainfall for later use.

A simple household setup may use a rain barrel connected to a roof downspout.

Possible non-drinking uses include:

• Watering ornamental plants
• Landscape irrigation
• Rinsing tools
• Other locally permitted outdoor uses

Collected rainwater can pick up material from roofs, gutters, storage containers, and the surrounding environment, so it should not automatically be treated as drinking water.

See our Rainwater Harvesting Guide for considerations on collection, storage, treatment, and testing.

Choose Water-Efficient Fixtures and Appliances

When an existing fixture or appliance needs replacement, water efficiency can be part of the purchasing decision.

Examples include:

• WaterSense toilets
• WaterSense showerheads
• Efficient faucet aerators
• High-efficiency washing machines
• Efficient dishwashers
• Weather-based irrigation controllers
• Soil-moisture-based controllers

Efficiency works best when products are correctly installed and maintained.

Review Your Water Bill

Your water bill is one of the easiest tools for understanding household use.

Compare:

• This month with previous months
• This season with the same season last year
• Periods when the home was occupied versus vacant
• Usage before and after fixture changes

An unexplained increase can point toward:

• A running toilet
• A plumbing leak
• An irrigation malfunction
• Changes in household routines

Water Conservation Beyond the Home

Households matter, but long-term water conservation also depends on farms, businesses, utilities, industries, and governments.

Agriculture

Potential strategies include:

• Improved irrigation scheduling
• Soil-moisture monitoring
• Drip and micro-irrigation where appropriate
• Better soil management
• Reducing conveyance losses
• Matching crops to local water availability

For a broader discussion, see our Water Resources of the United States.

Businesses and Industry

• Reuse process water where practical.
• Recycle cooling water.
• Monitor high-use processes.
• Repair leaks.
• Improve cleaning procedures.
• Use reclaimed water where suitable and permitted.

Communities and Utilities

• Repair distribution-system leaks.
• Modernize aging infrastructure.
• Improve drought planning.
• Encourage efficient landscaping.
• Support appropriate water reuse.
• Protect watersheds and drinking-water sources.

See our Source Water Protection Guide for more information.

Water Conservation and Drinking Water Filtration

Water conservation and water filtration solve different problems.

Conservation reduces unnecessary water use.

Filtration addresses particular drinking-water quality or taste concerns.

Home filtration may indirectly support conservation goals when it helps a household rely less on individually packaged bottled water, but a filter itself does not reduce total household water use unless it changes another water-use behavior.

Gravity-Fed Filtration

Countertop gravity-fed systems operate without a permanent plumbing connection and do not create the continuous reject-water stream associated with conventional reverse-osmosis operation.

If you are comparing gravity-fed options, see our Berkey® Water Filter Systems Guide and Water Filter Test Results.
