How Much Water Does the Average Person Use?

Updated May 3rd, 2024

The United States is deemed the “Land of Plenty,” partly for its abundant water resources. It’s home to the largest freshwater lake system worldwide (the Great Lakes), which holds six quadrillion gallons of water. And let’s not forget the mighty Mississippi River, which flows at around 4.4 million gallons per second, supplying water to about 15 million people along the way.

Usually, the water from these and other sources is treated and delivered to homes and businesses, where it’s used for a broad variety of purposes, such as bathing, showering, washing our clothes and dishes, preparing our favorite meals, etc. Heck, some of us even use it for fun, outdoor water games, and filling swimming pools. But how much of it do we use every day? Where does it come from? Will it ever run out? Let’s settle these concerns once and for all.

Daily Water Usage in a Typical American Home: The Numbers

The Environmental Protection Agency (EPA) reports that the typical American household uses over 300 gallons of water per day. To some people, that amount might not seem like a lot, but when you consider that there are over 130 million households in America, the combined usage is massive!

Based on the most recent data available from the United States Geological Survey (USGS), Americans used an estimated 322 billion gallons of fresh and saline water per day in 2015. That means on any given day in that year, Americans withdrew enough water to fill 1,163 Empire State Buildings. Again, these are 2015 numbers. Until more current data becomes available, we can assume that those numbers have probably increased somewhat over the past few years.

Where does the water come from, and where does it go?

Well, based on 2015 data, the majority – 61.5 percent or 198 billion gallons per day – of water withdrawals came from surface water, such as rivers, lakes, streams, etc. Approximately 25 percent of freshwater withdrawals, totaling 82 billion gallons per day, was from groundwater. The remaining 13 percent came from saline sources.

How much water does the average family use per day?

Toilets use 24% of water in US homes

As for where the water goes, a survey conducted by the Water Research Foundation revealed that toilets use 24 percent of the 300 gallons of water used per day by the average American family, 20 percent is used for baths and showers, 19 percent is from the faucet, 17 percent is used to operate washing machines and dishwashers, 8 percent is used for various activities, and a staggering 12 percent is from water leakage.

Here’s a breakdown of EPA estimates on the number of gallons the average person in America uses in each room each day:

Indoor sources of water use Gallons per person, per day
Toilet 18.5
Washing Machine 15
Shower 11.6
Faucet 10.9
Dishwasher 1


Of course, other external sources consume plenty of water. For instance, if you have a big yard full of thick, green grass, you likely water it every day with a hose to maintain its lush, vibrant look. Or perhaps you have a sprinkler system in place to do the job.

Watering a large lawn in dryer regions can account for more than half of a household’s water use. Worse, some sprinkler systems are inefficient, with only half of the water making it into the soil. The rest of the water is lost due to wind, runoff, evaporation, and poor design.

Swimming Pools Also Consume Large Volumes of Water

A regular swimming pool will hold at least 10,000 gallons of water, with larger pools holding well over 20,000 gallons. In hot regions, evaporation can easily remove up to a quarter-inch of water daily in a 14 x 24-feet pool, which works out to over 60 gallons per day!

Before we move on to the next section, keep in mind that the estimates stated in the table above can change based on how many people you have in your household, your house’s size, and several environmental factors surrounding your home. Also, be mindful that your household water use can be directly proportional to the number of people living in your area.

Some of the states with the highest household water usage over the decade experienced the most population growth. States, such as Utah, Idaho, Texas, and Florida, have seen increases in their average water usage per person, possibly due to population growth. However, other factors, like climate change, can dramatically affect water usage in your home.

Will America Ever Run Out of Water?

There’s no definite answer to this question, but it’s important to note that households aren’t the biggest consumers of water in the U.S. The agricultural industry uses up to 70 percent of clean drinking water globally. This makes sense since plants need water to grow and produce, and animals need water to drink to remain alive and healthy.

Technically, we aren’t running out of water on a whole – we’re running out of access to clean drinking water. And with factors like climate change, rapid population growth, and more frequent storms, fires, and drought, gaining access to clean drinking water gets more challenging every day.

To make things worse, researchers at NASA discovered that 21 out of 37 of the world’s largest aquifers have depleted lower than they can sustain the populations that rely on them. In other words, we’re using water from these aquifers faster than they are being replenished. Even Americans are at risk. A recent Reuters report shows that 96 water basins out of the 204 supplying most of the country with fresh water could fail to meet monthly demand in 2071.

How Can You Lower Your Daily Water Usage?

For starters, learn more about your home water usage. Check your latest water bill to see how much water you used for the month. Most water bills will include a monthly comparison for the previous 12 months.

Take things further by looking at some of the water-reliant fixtures and appliances in your home, including your toilet, dishwasher, washing machine, and water heater. For instance, by replacing old, inefficient toilets and other fixtures with WaterSense models, the average family could save thousands of gallons of water and reduce their water costs per year. You can also retrofit your older appliances with WaterSense-labeled fixtures or upgrade to newer ENERGY STAR certified appliances. These simple actions can end up saving you hundreds of dollars a year!

Invest in a Smart Water Monitor & Automatic Shutoff Valve

Another smart thing to do is keep watch for leaks, including toilets that “run” continuously, dripping faucets, and leaking shower heads. According to the EPA, a typical family can waste 180 gallons a week (9,400 gallons a year) from household leaks. Invest in a smart water monitor and automatic shutoff valve by purchasing Flo by Moen.

Several other simple strategies include cutting back on the time you spend running the faucet for daily tasks, like taking a shower, brushing your teeth, or washing dishes by hand. But above all, investing in a water filtration system helps ensure access to clean drinking water in your home. Springwell’s water filtration systems are uniquely designed to target and remove water contaminants that could wreak havoc in your home and severely impact your health and that of your loved ones.

Final Thoughts

The average American household uses a lot of water – 300 gallons a day, to be exact. Unless we find ways to cut back on our water usage, we will be heading down a dry path. Thankfully, we’ve provided some simple steps above to help keep your household water usage in check, saving you money and helping to preserve local water supply and quality at the same time.
