How much water should I keep on hand in case of an emergency?

The CDC recommends storing 1 gallon of water per person each day in case of an emergency. 1/2 gallon to drink, 1/4 gallon to cook with, and 1/4 gallon to wash with This equates to around 30 gallons of water storage per adult per month and 360 gallons of water storage per adult per year.

Please keep in mind that this water storage calculator is merely a suggestion. If you’re active or live in a hot region, 1 gallon of drinking water per person, per day is preferable. According to the CDC (Centers for Disease Control and Prevention), you should drink at least two quarts (half a gallon) of water every day in an emergency, and more if you’re pregnant or live in a hotter environment. They do recommend saving at least 1 gallon of water per person every day for drinking, cleanliness, and food preparation, among other things. The more drinking water you have on hand, in my opinion, the better off you and your family will be.

It’s critical to remember to sanitize/disinfect your water storage with bleach on a regular basis when storing water.

According to recent statistics, most individuals would not have access to potable water in the event of an emergency. I couldn’t bear seeing my family go hungry or thirsty, thus I believe water and food storage to be a must in the event of an emergency or natural disaster.

According to the American Red Cross (see page 24), you should keep at least one gallon of water per person each day in case of an emergency. Water is also required for cooking (food preparation) and cleaning (hygiene).

How much water should you store for 1 month or two weeks?

Water Uses1 Month of Water for 1 PersonTwo Weeks of Water for 1 Person
Drinking-Water16 gallons8 gallons
Cooking (food preparation) Water8 gallons4 gallons
Washing (hygiene) Water8 gallons4 gallons

Consider putting aside at least a two-week supply of water for each family member. If you can’t save this much, store as much as you can.

Never ration water if supplies are running low. Drink as much as you need today and save the rest for tomorrow. Reduce your activity and keep cool to reduce the amount of water your body requires.

What is the bare minimum of water need to survive each day?

2 quarts of drinking water per person per day should be the absolute minimum requirement for the “typical” individual. It should be upwards of 1 gallon per person each day for more active persons (particularly if they sweat a lot). Remember to factor in normal temperatures and weather conditions. A gallon of water per person per day is required for drinking, cooking, and washing.

You should consider the following, according to ready.gov:

  • Children, nursing mothers, and the elderly may require additional water.
  • Additional water may be required in the event of a medical emergency.
  • If you live in a hot climate, you may need to drink more water. Water consumption might increase in extreme heat.

How To Sanitize Water Storage

When keeping water, it’s crucial to remember to sanitize the container. Bleach is a fantastic technique to sanitize your water storage.

To sterilize a water storage tank, how much bleach is required?
The table below illustrates how much bleach is required to purify/disinfect 1,000 gallons of water, 300 gallons of water, 275 gallons of water, 55 gallons of water, and 1 gallon of water. Bleach with fresheners or perfumes should not be used.

Water that is crystal clear
Add 1/8 teaspoon (8-10 drops or about 0.75 milliliters) of home liquid bleach to 1 gallon (16 cups) of clear water, according to the CDC (Centers for Disease Control and Prevention).

Water that is cloudy
The CDC also recommends mixing 1 gallon (16 cups) of turbid water with 1/4 teaspoon (16 drops or 1.5 milliliters) of household liquid bleach.

*Treating water with household bleach containing 5.25-8.25 percent chlorine

Be careful! Don’t let children get their hands on the bleach. drinking fully concentrated bleach can kill you.

Water Purification Devices as a Water Storage Alternative

Because it is unlikely that your family would be able to conserve enough water for each family member for several months, a reliable water purifying device is strongly recommended. Personally, I like water purifiers because they are much easier to use than storing gallons upon gallons of water; but, even with a good water purifier, at least two weeks of water storage is required.
