Average Water Consumption Per Day
Some studies suggest that the average healthy adult will get enough water if they take in about 11.5 cups (2.7 liters) to 15.5 cups (3.7 liters) of total fluid. Plain water consumption varies Getting enough water every day is important for health. Drinking water can prevent dehydration, which may cause unclear thinking, mood change, overheating, constipation, and kidney stones.
Plain water consumption varies by age, race/ethnicity, and socioeconomic status. For healthy individuals, the average daily water for men is about 15.5 cups and for women about 11.5 cups. That might mean you need only four to six cups of plain water, depending on other fluid sources such as coffee, tea, juice, fruits, and vegetables.
Each American uses an average of 82 gallons of water a day at home (USGS, Estimated Use of Water in the United States in 2015). We can all use at least 20 percent less water by installing water-efficient fixtures and appliances. The European Food Safety Authority recommends 2.0 litres (70 imp fl oz; 68 US fl oz) of total water per day for women and 2.5 litres (88 imp fl oz; 85 US fl oz) per day for men.
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! While daily water use is high due to household chores and hygiene, the amount of water humans drink is much lower.
The average person drinks under 1 gallon (3.7 liters) of water daily. The average American uses 80-100 gallons of water per day for personal consumption. Daily water use includes toilet flushing (24%), showering (20%), faucet use (19%), and laundry (17%).
On average, per person uses 82 gallons or 310 liters of water per day. And, the average water usage per person per month is approximately 2400 gallons. The average family of 4 people would use around 10,000 gallons per month or for 30 days.
This may highly vary depending on the geographical locations and the weather of the countries. The National Academies of Sciences set the adequate intake for total water (from all beverages and food combined) at 3.7 liters per day for adult men and 2.7 liters per day for adult women.
