How to Reduce Household Water Use During a Shortage

When a local water shortage hits, cutting your household’s water use isn’t just about saving money—it’s about keeping water available for essential needs like drinking, cooking, and firefighting. This guide walks you through practical, step-by-step actions to reduce your water consumption quickly and effectively, from quick fixes to longer-term habits. You’ll learn what to do first, how to track your progress, and how to avoid common pitfalls.

What You’ll Need

• Bucket (for capturing water while waiting for it to heat up)
• Adjustable wrench (for checking and fixing leaks)
• Food coloring or leak detection tablets (for toilet leak tests)
• Timer or phone with stopwatch (for timing showers)
• Large jug or container (for storing drinking water)
• Spray nozzle for garden hose (if you have outdoor plants)
• Notebook or app for tracking your water meter readings

Step-by-Step

1. Read your water meter. Locate your water meter (usually in a box near the street or in your basement). Write down the current reading. This gives you a baseline to measure your progress. Check it at the same time each day to see your daily usage.
2. Fix leaks immediately. A dripping faucet can waste up to 3,000 gallons a year. Check all faucets, showerheads, and visible pipes for drips. For toilets, add a few drops of food coloring to the tank. If color appears in the bowl without flushing, you have a leak. Replace worn washers or flapper valves—a simple, cheap fix.
3. Take shorter showers. Set a timer for 5 minutes. Turn off the water while soaping up, shaving, or shampooing. If you can, install a low-flow showerhead (2.0 gallons per minute or less). A 5-minute shower with a low-flow head uses about 10 gallons; a 10-minute shower with an older head can use 25+ gallons.
4. Turn off the tap while brushing teeth or washing hands. This simple habit can save up to 4 gallons per minute. Wet your brush, turn off the tap, brush, then turn it on to rinse. Same for washing hands: wet, turn off, lather, turn on to rinse.
5. Only run full loads. Wait until you have a full load of laundry or dishes before running the washing machine or dishwasher. If you must run a partial load, use the appropriate water-level setting. Hand-washing dishes? Fill one basin with soapy water and one with rinse water instead of letting the tap run.
6. Collect and reuse water. Place a bucket in the shower to catch cold water while you wait for it to warm up. Use this to water plants, flush the toilet (pour it into the bowl), or clean. Similarly, collect water from rinsing vegetables or boiling pasta (after it cools) for plants.
7. Limit outdoor watering. In a shortage, outdoor watering is usually the first thing to cut. If you must water, do it early morning or late evening to reduce evaporation. Use a watering can for specific plants rather than a sprinkler. Skip washing your car, or use a bucket and sponge with a quick rinse.
8. Use your dishwasher instead of hand-washing. Modern dishwashers use less water than hand-washing—about 3-5 gallons per load vs. up to 20 gallons by hand. Scrape food off plates (don’t rinse) and run full loads.
9. Store drinking water in the fridge. Keep a pitcher of tap water in the refrigerator so you don’t run the tap until it’s cold. This saves water and energy.
10. Monitor your meter daily. Each day, read your meter and note the usage. If it spikes unexpectedly, you likely have a leak. A sudden increase of 1,000 gallons in a month often indicates a running toilet or a hidden pipe leak.

Common Mistakes

• Running the tap for cold water. Instead of letting it run, fill a pitcher and keep it in the fridge.
• Using the garbage disposal. It requires a lot of water to flush food down. Instead, compost food scraps or throw them in the trash.
• Overwatering plants. Most plants need less water than you think. Stick your finger in the soil—if it’s moist an inch down, skip watering.
• Ignoring a silent toilet leak. A flapper leak can waste 200 gallons a day without making a sound. The food coloring test is essential.
• Washing half loads. It’s tempting to run a small load, but it wastes water and energy. Wait for a full load.
• Not checking for outdoor leaks. A leaky hose bib or sprinkler system can waste hundreds of gallons unnoticed. Check connections regularly.

Tips

• Install aerators on faucets. They mix air with water, reducing flow while maintaining pressure. They cost a few dollars and can cut faucet water use by 30%.
• Use a shower bucket. The water you catch while waiting for it to heat up can be used for flushing toilets or watering plants.
• Mulch your garden. A layer of mulch around plants reduces evaporation and keeps soil moist longer.
• Wash produce in a bowl. Fill a bowl with water to wash fruits and vegetables, then reuse that water for plants.
• Know your local restrictions. Your water provider may have specific rules (e.g., watering days, bans on filling pools). Follow them—they’re designed to ensure equitable distribution.
• Consider a low-flow toilet. If you’re replacing a toilet, choose a model with a 1.28 gallons per flush rating. Older toilets use 3.5-7 gallons per flush.

Troubleshooting

• Your water bill is high despite following steps. Do a thorough leak check. Read your meter, then don’t use water for two hours. If the meter moves, you have a leak. Check toilets, faucets, and irrigation systems. If you can’t find it, call a plumber.
• You can’t take a 5-minute shower because you have long hair. That’s fine—the goal is to reduce, not to be miserable. Turn off the water while lathering and shampooing, then turn it back on to rinse. That alone can cut your shower water use in half.
• Your dishwasher isn’t full but you need a specific dish. Hand-wash that one dish with a small amount of water in a basin, then reuse that water for plants or flushing. Don’t run the dishwasher for one item.
• You have a lawn that’s turning brown. In a shortage, letting the lawn go dormant is acceptable—it will recover when rain returns. Focus water on trees and shrubs, which are more expensive to replace.
• Your water pressure is too low for a shower. Low-flow showerheads can be problematic in some homes. Remove the flow restrictor if needed, or use a hand-held showerhead with a pause button.

Frequently Asked Questions

How much water does the average household use?

In the US, the average is about 300 gallons per day per household, but that varies widely. During a shortage, aim to cut that by 20-30% with simple behavioral changes.

Is it safe to drink tap water during a shortage?

Yes, unless your water provider issues a boil water advisory. Shortages are about quantity, not quality. Your tap water remains safe to drink.

How do I check for a toilet leak?

Add a few drops of food coloring to the toilet tank. Wait 15 minutes without flushing. If color appears in the bowl, you have a leak. Replace the flapper valve—it’s a cheap, easy fix.

Can I water my garden during a water shortage?

It depends on local restrictions. In many shortages, outdoor watering is restricted or banned. If allowed, water only with a watering can or drip irrigation, and only in the early morning or evening to reduce evaporation.

How can I save water when washing dishes by hand?

Fill one basin with soapy water for washing and another with clean water for rinsing. Don’t let the tap run. If you have a dishwasher, use it—it’s more efficient than hand-washing.

What should I do if I find a major leak?

Turn off your main water shut-off valve immediately, then call a plumber. A major leak can waste thousands of gallons if left unchecked.
