How Much Water To Store:
- A good rule to go by is that each person will need one gallon of drinking water per day.
- Pregnant women, children, the elderly, those who are ill, and people living in extreme climates (either really hot, or really cold) should plan for 2 gallons per day.
- This gallon of water per day is the amount needed for drinking only. Store an additional gallon of water per person, per day to cover water that will be needed for cooking and hygiene use.
- If you have pets, remember to put water back for them too. If you have a medium to large dog, 1 gallon of water should be stored for them per day. Smaller dogs and cats will need 1/2 a gallon per day.
- Pets that live in extreme climates, like people, will need that amount doubled.
Best Way To Store Water:
- Choose a place that has little or no light, and try to find a location that is not too cold.
- Choose jugs or containers that are BPA free.
- If buying gallons or containers of water from a store, choose ones labeled 'drinking water' and NOT 'distilled water.' Distilled water tends to absorb the taste of the container. Also, distilled water is nothing more than processed tap water that has been condensed back into liquid form. This process removes fluoride and electrolytes. Lack of fluoride could heighten chances of dental problems, and your body needs electrolytes, such as potassium, chloride, and sodium to stay hydrated.
Shelf Life Of Store Bought Water:
- Store bought drinking water comes with an expiration date on it, usually a year or 2, but according to the FDA it has an indefinite shelf life. (see 4th paragraph under 'FAQ's about Bottled Water')
How To Prepare Your Own Water Containers For Storage:
- Be sure that each container has a tight fitting lid. That is very important.
- Clean the food grade BPA free plastic or glass container(s) by washing the inside, outside, and the lid(s) with hot soapy water.
- Sanitize the inside and outside of container(s) and lid(s) using a solution of 1 teaspoon non-scented household bleach per quart of water.
- Be sure and thoroughly rinse the container(s) and lid(s) with clean water.
How To Prepare (Non-Store Bought) Water For Storage:
Before I get into treating your tap water, I want to say that once you treated your water you should only consider it pure for 6 months. Since you shouldn't add more bleach to water that was previously treated with bleach, please just sanitize the containers and fill them with straight tap water before storing them.
Date the containers and keep them in a dark place in the coolest area of your home or wherever your storage is located. This water will be safe as is for up to 6 months without any further treatment as long as you filled them during a time that you didn't have a boil order or anything going on.
If you plan to store water in larger tanks for future drinking, be sure that you save smaller containers that are of quart, gallon, or 5 gallon sizes so you can treat smaller amounts of water at a time. I can't express how important it is to remember to store back bleach, droppers, and measuring spoons.
If your stored tap water has been sitting for over 6 months from the date you filled them, you'll need to treat the water before drinking it or using it for cooking. This water and bleach mixture will need to sit at least 30 minutes before drinking it to ensure that it has been properly purified. After sitting for the 30 minute period, there should be a slight chlorine scent to it.
- use 2 drops of bleach for 1 quart of clear water
- use 4 drops of bleach for 1 quart of water if it looks cloudy
- use 8 drops of bleach for 1 gallon of clear water
- use 16 drops of bleach for 1 gallon of water that looks cloudy
- use 1/2 teaspoon of bleach for 5 gallons of clear water
- use 1 teaspoon of bleach for 5 gallons of water that looks cloudy
After the water has been treated, be sure and date the container again. This water is only good for 6 months after the treatment date.
Alternative Boiling Water Treatment:
In the event that you have ran out of bleach to treat your water, or if you're allergic to bleach, you should use a boiling method to purify your water.
- Bring water to a rolling boil and let it stay at the rolling boil for a minimum of 1 minute.
- Let the water cool before drinking it or storing it.
- If you choose to store water once you have boiled it, remember to date it. It is only safe for 6 months after boiled. It should be boiled again if not used within the 6 month time period.
Alternative Iodine Tablet Purification:
- I'm not familiar with using iodine tablets. If you choose to stock these back and use them, you should follow the manufacturers instructions that come with them.
- Long-term safety after using iodine tablets isn't clear, so this should be an alternative for water that will be used as soon as the manufacturer's instructions state it is safe to use it. Water treated with this should not be set back in storage for any length of time.
- If you haven't used iodine tablets before and haven't been exposed to iodine in general, be cautious because some people are allergic to it.
