A natural disaster or other emergency could cut off water access for weeks. Storing your own supply addresses your most important demand in this situation. Although water does not "go bad" in the aforementioned way that food does, information technology can breed harmful bacteria if you practice not purify information technology or store it in safety conditions. The other hazard is chemic contamination, either from sure types of plastic containers, or from chemical vapors that pass through the walls of the water containers.

Make up one's mind how much h2o to store. The boilerplate person needs 1 gallon (4 liters) of water each day, half for drinking and one-half for food training and hygiene. Increase this number to ane.5 gallons (five.five L) per person or more for children, nursing mothers, and ill people, and for anyone in a hot or high-altitude climate. Based on these numbers, attempt to shop a 2 calendar week supply for your household.^[1] In case of an emergency evacuation, shop a three twenty-four hour period supply in easily transportable containers.^[2]
- For example, ii healthy adults and one child need (one gallon or 3.8 liters / developed) x (2 adults) + (one.five gal or 5.7 liters / kid) 10 (1 kid) = 3.5 gallons (13.25 liters) per day. A 2 week supply of water for this household is (3.5 gallons or 13.25 liters/ day) x (14 days) = 49 gallons (185.5 liters). A 3 day supply would be (three.5 gallons or 13.25 liters/twenty-four hour period) x (iii days) = 10.5 gallons (40 liters).

Consider bottled water. ^[iii] In areas that regulate bottled water, including the U.S. and E.U., sealed bottles of water are already germ-free and will stay skillful indefinitely. If y'all get this road, yous practise not need to worry nearly selecting appropriate containers or purifying the water.^[four]
- Cheque the label for certification by the IBWA (International Bottled Water Association), NSF (National Sanitation Foundation), or UL (Underwriters Laboratories). These demonstrate the product has met safe and quality standards.^[5] This is more important in countries that do not regulate bottled water.

Select nutrient course containers. Plastic food or beverage containers marked "HDPE" or with a #two recycling symbol are first-class options.^[six] Plastics #4 (LDPE) and #5 (PP) are besides safe, as is stainless steel.^[7] Never reuse a container that held anything besides food and drink, and only use brand-new empty containers if they are marked "food class," "food condom," or with a knife and fork symbol.
- Milk and fruit juice go out residuum that is difficult to remove and encourages bacterial growth. Practice not reuse containers that held these drinks.^[viii]
- Glass jars are a last resort, since they tin can hands interruption in a disaster.
- Traditional unglazed pottery jars can help go along water cool in warm climates. Use 1 with a narrow oral cavity, hat, and tap if possible to encourage sanitary handling.^[9]

Avoid containers made from hazardous plastics. Wait for the resin identification lawmaking on plastic containers, which typically consists of a number printed next to the recycling symbol. Avert containers marked "iii" (for polyvinyl chloride, or PVC), "six" (for polystyrene, or PS), and "7" (for polycarbonate). These materials can be hazardous to your health.

Make clean the containers thoroughly. Launder them with soap and hot water, and then rinse. If a container previously held nutrient or beverage, disinfect it with one of the following methods:
- Fill with h2o and mix in ane tsp (v mL) liquid household bleach for every quart (approximately 1 liter) of water. Swish to touch all surfaces, and then rinse well.^[10]
- For stainless steel or heat-safety glass, submerge in boiling water for x minutes, plus 1 minute for each ane,000 ft (300 m) of elevation above an distance of 1,000 ft (300 m).^[eleven] This is the best method for steel, since chlorine bleach can corrode the metal.^[12]
6
Disinfect water from dangerous sources . If your tap water is not safety to potable or if y'all go your water from a well, disinfect it right before storage. The best way to do this is to bring the water to a rolling boil for 1 minute, or three minutes at elevations higher up v,000 ft (one,000 m).^[xiii]
- If you lot cannot eddy the h2o, or exercise not desire to lose water past humid information technology, bleach is the side by side best option:^[14]
- Mix in ½ tsp (2.5 mL) of unscented, additive-free bleach for every 5 gallons (19 liters) of water. Double the amount of bleach if the water is cloudy or discolored.
- Let the water sit for half an hour.
- If you lot cannot smell a faint chlorine scent, repeat treatment and let sit some other 15 minutes.
- In an emergency, you can likewise disinfect small-scale amounts of h2o with water purification tablets. Withal, use these sparingly, as excessive utilise can impair thyroid function.^[fifteen]
7
Filter out contaminants. Humid or chlorine will kill microorganisms, but they will not remove lead or heavy metals. If your water is contaminated past runoff from farms, mines, or factories, cascade it through an activated carbon filter and a reverse osmosis (RO) filter.^[16]
- Y'all tin can brand your own filter out of common materials. While not as effective as a commercial filter, it will remove sediment and some toxins.

Seal the container tightly. Take care non to bear upon the inside of the cap with your fingers, to avoid contamination.^[17]

Label the container. Write "drinking water" on the side, along with the date you bottled information technology or purchased it.

Shop in a cool, dark place. Calorie-free and rut tin damage containers, especially plastic ones. Sunlight can also cause algae or mold to grow in clear containers, even sealed, store-bought bottles.^[18]
- Practise not store plastic containers near chemical products, especially gasoline, kerosene, and pesticides. Vapors can pass through some plastic containers and contaminate the water.^[19]
- Store a three twenty-four hours supply in pocket-sized containers most an exit, in case of an emergency evacuation.

Check on the supply every six months. If stored properly, unopened, store-bought bottled h2o should stay good indefinitely, even if the bottle has an expiration engagement.^[20] If you bottled the water yourself, replace it every 6 months.^[21] Replace plastic containers when the plastic becomes cloudy, discolored, scratched, or scuffed.^[22]
- You can drink or use the former supply of water earlier replacing it.
5
Open up 1 container at a time. If you need to use your emergency supply, store open up h2o containers in a fridge or common cold location. Use an open container within 3 to v days in the refrigerator, 1 to 2 days in a common cold room, or a few hours in a warm room.^[23] After that, purify the remaining h2o once again past boiling it or calculation chlorine.
- Drinking directly from the container or touching the rim with muddied hands increases the risk of contamination.

For emergencies, keep a portable h2o filter, like a Lifestraw, on hand. These can exist used to filter leaner out of h2o without the use of estrus.^[24]
Consider freezing some of your water and so yous have a short-term style to store perishables if the power goes out. Freeze water in plastic containers with a couple inches (a few centimeters) of caput space, as the expanding water ice can break drinking glass or overfilled containers.^[25]
H2o kept in long-term storage tin can gustation "flat" due to the loss of air, particularly if it was boiled. Cascade the water in long streams betwixt ii containers to aerate the water once more and improve taste.

If y'all discover a leak or hole in the containers afterwards having stored the water, practise not beverage from the container.
Practice not use scented or color-safe bleach to purify h2o, or bleach with added cleaners, or bleach with a greater than 6.0% concentration. Bleach gradually becomes less effective if the canteen has been opened, so use a new container for best results.^[27]
Iodine tablets and other not-chlorine water treatments are not recommended, since they impale fewer microorganisms than chlorine.^[28]
