Water for Drinking:

Each day we consume various forms of water. Some of which is in our foods and others in the liquids we drink. We need 1 gallon of water for each survival day. That means 16 cups of water per day.

Water for Washing Hands and Hygiene:

How often do you wash your hands throughout the day? Or running water while brushing your teeth? When the faucet is running, there is more water flow than you may think. An old faucet can use up to 5 gallons per minute. A newer faucet flows about 2 gallons per minute. So an average daily water usage in this category might be 2 to 3 gallons per minute.

Water for Cooking:

This category amount depends on what you are eating each day. It can vary from food to food. But I need to estimate an average. So let’s  say that you might consume more or less 1 gallon of water per day for cooking.

Water for Washing Dishes:

This category of water use can vary. Generally, a modern dishwasher will use much less water than you do by hand. A modern dishwasher uses less than 4.25 gallons of water per cycle. An old model uses 5.8 gallons. If you are hand washing dishes, the amount of water you will consume varies depending on your method.

I will guess that water consumption for hand washing dishes may range from 10 to 30 gallons. Most people in the modern world use an automatic dishwasher. So the average consumption of water is about 8 gallons.

Water for Flushing the Toilet:

You are consuming at least 2 gallons of water in each flush. So the question is, how many times do you flush every day? That depends of course, but on an average, the number is 6 to 8 times. So the amount would be 20 gallons per day.

Water for Washing Clothes:

It depends on how many are in the household. It also depends on the lifestyle which may or may not warrant more clothes washing than others. Most people don’t wash the laundry every day but once a week. A top-loading washing machine consumes lots of water. On average 40 gallons per load. A front-loading washing machine may consume on average about 20 gallons per load. So if you only wash one load, the average consumption will be 4 gallons of water per day.

Water for Bathing:

Most people bathe in a full bathtub of water. A half-full bathtub of water may consume about 50 gallons of water. A modern shower head may flow about 2 or 3 gallons per minute. Other shower heads will blast out much more than that. A ten-minute shower will use about 30 gallons of water. So a daily shower on average and usage of 30 gallons of water per day.

There will be wide variations of water usage. But according to my general estimations listed above, each person may consume 66 gallons of water per day.
