Basic Home Water Purification

Water from an unsafe source can be contaminated after a disaster, even if it does not smell, taste, or appear tainted. Unless you're positive the water you're going to drink is pure, you'll need to purify it to eliminate any disease-causing germs and microbes. The post-emergency water purification procedure is as follows:

  • Using a piece of cloth, sift solid particles from the water.

  • Bring this filtered water to a boil for about one minute.

  • Allow time for the water to cool. The cleansing of the water will not take place if this step is skipped.

  • Add 7 drops of liquid chlorine bleach every two-liter bottle of water, or 14 drops per gallon of water. To combine, stir everything together. The sole active element in the bleach should be (NaOCl) sodium hypochlorite at a concentration of 5.25 to 6%. Furthermore, it should be odorless and colorless.

  • The mixture should rest for half an hour.

  • You can drink the water if it smells like chlorine. If it still doesn't smell like chlorine, add the same quantity of bleach and let it sit for another thirty minutes. If the water still doesn't smell like chlorine, throw it out and look for another source.

  • The water in your home's plumbing, as well as what's in your refrigerator and the storage tank for the water heater may be emptied and purified for drinking. Drain and treat the water using the Red Cross post-disaster water treatment technique after turning off the gas or power to the heater.

  • You can use water from a toilet tank for personal hygiene but not for drinking if no chemicals have been added to the tank water. You may also utilize water from a hot tub or a swimming pool.

  • Water from a waterbed, a home heating system boiler, or a radiator should not be purified or consumed. Chemicals that cannot be eliminated by filtration might contaminate any of these water sources.
