Reduce Household Water Use During a Drought: A Practical US Guide

This guide shows you how to cut your household water use during a drought, saving hundreds of gallons a week without major expense. You’ll learn quick fixes, habit changes, and longer-term upgrades that work in any US home, plus what to do when your efforts aren’t enough. Start with the steps that give the biggest immediate savings—most take less than an hour.

What You’ll Need

• Adjustable wrench or pliers
• Screwdriver (flathead and Phillips)
• Bucket (2–5 gallon)
• Food coloring or leak detection tablets
• Timer or phone stopwatch
• Water-saving showerheads and faucet aerators (if replacing)
• Toilet tank bank or a plastic bottle filled with water (optional)
• Rain barrel (if allowed in your area)

Step-by-Step

1. Find and fix leaks first. A dripping faucet can waste 3,000 gallons a year; a running toilet can waste 200 gallons a day. Check toilets by adding a few drops of food coloring to the tank—if color appears in the bowl within 15 minutes without flushing, you have a leak. Replace the flapper (a $5 part) or tighten connections. For faucets, replace worn washers or O-rings. Even a small leak adds up fast.
2. Shorten your showers. Aim for 5 minutes or less. A standard showerhead uses 2.5 gallons per minute, so a 10-minute shower is 25 gallons. Cutting to 5 minutes saves 12.5 gallons per shower. Use a timer or a waterproof playlist to keep track. If you have a bathtub, fill it only halfway—a full tub can use 50 gallons.
3. Install low-flow fixtures. Replace your showerhead with a WaterSense-labeled model (2.0 gallons per minute or less). Install faucet aerators on kitchen and bathroom sinks—they mix air with water, reducing flow from 2.2 to 1.5 gallons per minute while maintaining pressure. These are inexpensive and take minutes to install with pliers. For toilets, if you have an older model (pre-1994, likely 3.5–5 gallons per flush), place a toilet tank bank or a filled plastic bottle in the tank to displace water, reducing each flush by 0.5–1 gallon. Do not use a brick—it can crumble and damage the mechanism.
4. Turn off the tap while brushing teeth, shaving, or washing hands. Running a faucet uses 2 gallons per minute. Turning it off while brushing (2 minutes) saves 4 gallons per person per day. For shaving, fill the sink with a few inches of water instead of running the tap. When washing hands, wet hands, turn off the tap, lather, then rinse—saves about 1.5 gallons each time.
5. Only run full loads of laundry and dishes. A washing machine uses 15–45 gallons per load (front-loaders are more efficient). Running half loads wastes water and energy. Wait until you have a full load. For dishwashers, scrape food off plates instead of rinsing—modern dishwashers handle food residue. If you wash dishes by hand, fill one basin with wash water and one with rinse water instead of running the tap.
6. Collect and reuse water. Place a bucket in the shower while waiting for the water to heat up—catch 2–5 gallons each time. Use that water to flush the toilet, water plants, or clean. Keep a pitcher of drinking water in the fridge so you don’t run the tap to get cold water. When washing vegetables or boiling pasta, pour the leftover water onto outdoor plants after it cools.
7. Water your lawn and garden wisely. Water only when needed—check by stepping on the grass: if it springs back, it doesn’t need water. Water early morning (before 10 a.m.) to reduce evaporation. Use a soaker hose or drip irrigation instead of a sprinkler—it delivers water directly to roots and reduces waste by up to 60%. Set a timer to avoid overwatering. In many drought areas, watering restrictions are in effect—follow local rules. If you must use a sprinkler, use an oscillating type and place a tuna can under it; when the can is full (about 1 inch), you’ve watered enough.
8. Reduce outdoor water use overall. Let your lawn go dormant—it will turn brown but usually recovers when rain returns. Sweep driveways and sidewalks instead of hosing them down. Wash your car with a bucket and sponge, and only rinse at the end. Cover your pool when not in use to prevent evaporation—an uncovered pool can lose 1,000 gallons a month in summer. If you have a pool, check the water level; if it drops more than normal, you have a leak.
9. Upgrade to high-efficiency appliances when possible. If your washing machine or dishwasher is old, replace it with an Energy Star model. A front-loading washer uses about 14 gallons per load vs. 27 for a top-loader. An Energy Star dishwasher uses about 3.5 gallons per cycle vs. 6–10 for older models. These upgrades save water and energy, but they cost money—if you can’t replace now, focus on full loads and shorter cycles.
10. Monitor your water bill and meter. Check your water meter before and after a two-hour period when no water is being used. If the meter changes, you have a leak. Track your monthly usage—if it spikes unexpectedly, investigate. Many utilities offer free water audits or rebates for efficient fixtures—check your local water provider’s website.

Common Mistakes

• Ignoring silent leaks. Toilet leaks are often silent—you only hear them if the flapper is badly warped. Use the food coloring test at least twice a year.
• Watering on a schedule. Automatic sprinklers water even after rain. Install a rain sensor or turn off the system during wet weeks.
• Overfilling the bathtub or pool. A full tub is 50 gallons; a half-full tub is 25. For pools, keep water level at the middle of the skimmer—not higher.
• Using the garbage disposal. It requires running water to flush food down. Instead, compost food scraps or throw them in the trash.
• Leaving hoses running. A garden hose can flow 10 gallons per minute. Always turn off the nozzle when not actively using it.

Tips

• Set a family challenge: see who can take the shortest shower. A little competition can cut usage dramatically.
• Keep a watering can by the kitchen sink to catch water from rinsing fruits and vegetables—use it on houseplants.
• When shaving, use a cup of water to rinse the razor instead of running the tap.
• If you have a septic system, reducing water use also reduces the load on your drain field—a bonus during droughts.
• During a drought, prioritize watering trees and shrubs over grass—they are more valuable and harder to replace.
• Check your local water authority’s website for drought stage levels and specific restrictions—they may offer free showerheads or rebates.

Troubleshooting

• Water pressure drops after installing a low-flow showerhead. This is normal. If it’s too weak, remove the flow restrictor (a small plastic disc) from the showerhead—but that defeats the purpose. Instead, try a different model with a wider spray pattern that feels stronger at the same flow rate.
• Toilet keeps running after replacing the flapper. The chain may be too tight or too loose. Adjust the chain so there’s a little slack, but not so much that the flapper doesn’t seal. Also check the overflow tube—if water is constantly running into it, the fill valve needs adjustment.
• You can’t find a leak but your bill is high. Check the outdoor spigots and irrigation system—leaks there are common. Also check the water softener (if you have one) for a stuck regeneration cycle. If you still can’t find it, contact your utility—they may help you pinpoint it.
• Your lawn turns brown despite watering. You may be watering too frequently but too little. Water deeply and less often—1 inch per week is enough for most lawns. Brown grass may also be a sign of fungus or pests, not lack of water.
• Rain barrel water smells. This is normal from stagnant water. Use it only for outdoor plants, not for drinking or washing. Add a screen to keep mosquitoes out, and empty it regularly.

Frequently Asked Questions

1. How much water can I realistically save per day? A typical household can save 30–50% of indoor water use by fixing leaks, shortening showers, and running full loads. That’s often 50–100 gallons per day for a family of four.
2. Is it safe to drink water from a rain barrel? No. Rain barrel water is not treated and can contain bacteria, bird droppings, and chemicals from your roof. Use it only for watering plants or washing outdoor items.
3. Can I wash my car during a drought? Many drought restrictions prohibit hosing down cars. If allowed, use a bucket and sponge, and only rinse at the end. Better: use a commercial car wash that recycles water.
4. What does “WaterSense” mean? It’s a US EPA program that certifies products that are at least 20% more water-efficient than standard models. Look for the label on showerheads, toilets, and faucets.
5. Should I let my lawn die during a drought? It’s usually best to let it go dormant—it will brown but likely recover. If you water, do it deeply and infrequently. If you have severe restrictions, prioritize trees and shrubs.
6. My water bill is high even though I’ve cut back. What now? Check for hidden leaks (toilet, irrigation, underground). If you can’t find one, contact your utility—they may have a high-usage alert system or offer a free audit.
