20 Interesting and Useful Water Facts
- Roughly 70 percent of an adult’s body is made up of water.
- At birth, water accounts for approximately 80 percent of an infant’s body weight.
- A healthy person can drink about three gallons (48 cups) of water per day.
- Drinking too much water too quickly can lead to water intoxication. Water intoxication occurs when water dilutes the sodium level in the bloodstream and causes an imbalance of water in the brain.
- Water intoxication is most likely to occur during periods of intense athletic performance.
- While the daily recommended amount of water is eight cups per day, not all of this water must be consumed in the liquid form. Nearly every food or drink item provides some water to the body.
- Soft drinks, coffee, and tea, while made up almost entirely of water, also contain caffeine. Caffeine can act as a mild diuretic, preventing water from traveling to necessary locations in the body.
- Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.
- Water dissolves more substances than any other liquid. Wherever it travels, water carries chemicals, minerals, and nutrients with it.
- Somewhere between 70 and 75 percent of the earth’s surface is covered with water.
- Much more fresh water is stored under the ground in aquifers than on the earth’s surface.
- The earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same water that existed on the earth millions of years ago is still present today.
- The total amount of water on the earth is about 326 million cubic miles of water.
- Of all the water on the earth, humans can used only about three tenths of a percent of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.
- The United States uses about 346,000 million gallons of fresh water every day.
- The United States uses nearly 80 percent of its water for irrigation and thermoelectric power.
- The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water.
- Approximately 85 percent of U.S. residents receive their water from public water facilities. The remaining 15 percent supply their own water from private wells or other sources.
- By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.
- The weight a person loses directly after intense physical activity is weight from water, not fat.
110 Ways to Conserve Water
There are a number of ways to save water, and they all start with you.
- When washing dishes by hand, don’t let the water run while rinsing. Fill one sink with wash water and the other with rinse water.
- Evaporative coolers require a seasonal maintenance checkup. For more efficient cooling, check your evaporative cooler annually.

- Run your washing machine and dishwasher only when they are full and you could save 1000 gallons a month.
- Avoid planting turf in areas that are hard to water such as steep inclines and isolated strips along sidewalks and driveways.
- Install covers on pools and spas and check for leaks around your pumps.
- Use the garbage disposal sparingly. Compost instead and save gallons every time.
- Plant during the spring or fall when the watering requirements are lower.
- Keep a pitcher of water in the refrigerator instead of running the tap for cold drinks, so that every drop goes down you not the drain.
- Check your water meter and bill to track your water usage.
- Minimize evaporation by watering during the early morning hours, when temperatures are cooler and winds are lighter.
- Wash your produce in the sink or a pan that is partially filled with water instead of running water from the tap.

- If your shower can fill a one-gallon bucket in less than 20 seconds, then replace it with a water-efficient showerhead.
- Collect the water you use for rinsing produce and reuse it to water houseplants.
- Divide your watering cycle into shorter periods to reduce runoff and allow for better absorption every time you water.
- We’re more likely to notice leaky faucets indoors, but don’t forget to check outdoor faucets, pipes, and hoses for leaks.
