How to Save Money on Your Water Bill

Conserving water is crucial for personal finance and environmental stewardship. Understanding household water consumption allows individuals to optimize usage, leading to tangible savings on utility bills. Implementing water-saving practices reduces monthly expenses and contributes to the broader sustainability of water supplies.

Water-Saving Practices Inside Your Home

Many opportunities exist within the home to reduce water consumption, particularly in high-use areas like the kitchen and bathroom. In the kitchen, efficient dishwashing practices can yield substantial savings. Running a dishwasher only when it is completely full can save thousands of gallons annually, as modern dishwashers are generally more water-efficient than handwashing, using around 3.5 gallons or less per cycle. When handwashing dishes, plugging the sink or using a basin instead of letting water continuously run for rinsing can conserve water. Scraping plates clean rather than pre-rinsing them before loading into a dishwasher also reduces water use.

Thawing frozen foods in the refrigerator overnight eliminates the need for running water. Washing fruits and vegetables in a bowl of water, rather than under a running tap, and then reusing that water for houseplants, offers a simple method to save. Keeping a pitcher of drinking water in the refrigerator also prevents running the tap until the water gets cold.

The bathroom accounts for a significant portion of indoor water use, offering considerable potential for savings. Installing low-flow showerheads and faucet aerators can dramatically lower water usage without sacrificing water pressure. WaterSense-labeled products use at least 20% less water. Limiting shower duration to five minutes can save a substantial amount of water, with a 2.5 gallons per minute (GPM) showerhead saving 12.5 gallons per shower. Turning off the faucet while brushing teeth or shaving also prevents unnecessary water flow, conserving several gallons per minute.

Toilets represent another major water consumer in the bathroom. Replacing older, inefficient toilets (which can use up to 7 gallons per flush) with WaterSense-labeled high-efficiency models, using 1.28 gallons per flush (GPF), can save thousands of gallons annually. Even without replacing a toilet, a conversion kit or simply placing a weighted plastic bottle in the tank can reduce water per flush. For laundry, always running the washing machine with full loads maximizes efficiency and can save hundreds of gallons per month. Choosing ENERGY STAR labeled washing machines, which use 25% less energy and 33% less water than other models, provides further savings.

Water-Saving Practices Outside Your Home

Outdoor water use, particularly for landscaping, often accounts for 30% to 60% of a household’s water consumption. Adopting xeriscaping, a landscaping approach that minimizes water use, can reduce outdoor water consumption by 50-75% by utilizing drought-tolerant plants. Grouping plants with similar water needs into hydrozones and watering them according to specific requirements prevents overwatering some areas and underwatering others.

Efficient irrigation systems are paramount for outdoor water conservation. Drip irrigation, which delivers water directly to plant roots through a network of pipes or emitters, is highly efficient, saving 60-70% more water compared to traditional sprinklers by minimizing evaporation and runoff. Smart watering schedules, based on plant needs and local weather conditions, ensure that irrigation occurs during cooler hours, such as early morning, to reduce water loss from evaporation. Avoiding watering during windy conditions further minimizes evaporation.

Mulching is a highly effective practice for outdoor water retention. Applying a 2-4 inch layer of organic mulch, such as shredded bark or straw, over planting beds creates a protective barrier that shades the soil, reducing water evaporation by up to 58.8%. This practice helps maintain consistent soil moisture levels, which in turn reduces the frequency of watering needed and supports healthier plant growth.

For car washing, using a bucket and sponge instead of a continuously running hose can significantly cut water usage. Alternatively, commercial car washes often employ water recycling systems, making them a more water-efficient option than home washing.

Pool maintenance also offers water-saving opportunities. Using a pool cover can reduce water loss from evaporation by up to 95%, which can save thousands of gallons of water annually for a standard-sized pool. Pool covers also help retain heat, reducing the need for continuous heating and chemical adjustments. Lastly, rainwater harvesting, through the use of rain barrels, allows for the collection of precipitation from rooftops for later use in outdoor watering, reducing reliance on municipal water supplies.

Detecting and Preventing Water Loss

Unintended water loss from leaks can significantly increase utility bills and potentially cause structural damage to a home. Prompt detection and repair of leaks are important to prevent costly expenses and maintain property integrity. A dripping faucet, even a slow one, can waste hundreds of gallons of water per month, leading to higher water bills. Signs of a leaky faucet include visible drips, water stains, puddles around the sink area, or even unusual noises. Checking for leaks in visible pipes and fixtures regularly can help identify issues early.

One effective method for identifying leaks, particularly hidden ones, is to monitor the home’s water meter. To perform this test, ensure all water-using appliances and fixtures are turned off both inside and outside the home. Record the current reading on the water meter, then wait for a period, typically 1-2 hours, without any water use. If the meter reading has changed after this period, it indicates a leak somewhere in the system. The small flow indicator, often a triangle or star shape, on the meter will spin if water is moving through, even subtly.

To check for toilet leaks, a simple dye test can be performed. Add a few drops of food coloring or a dye tablet to the toilet tank and wait 20-30 minutes without flushing. If colored water appears in the toilet bowl, it indicates a leak, most commonly from a worn flapper valve. These leaks can often be silent, continuously refilling the tank and wasting water.

Beyond financial implications, unaddressed leaks can lead to significant property damage, including weakened building materials, mold growth, and compromised structural integrity, which can incur expensive repairs. Regular maintenance checks of plumbing and irrigation systems are a proactive step in preventing these issues, ensuring that minor problems are identified and rectified before they escalate.
