Water Purification – Purifying Water for Long Term Storage

In this video the Okieprepper discusses in depth how to purify bulk water supplies for long term storage using Stock Chlorine. Many people use bleach to purify water for the short term, but bleach begins to degrade in 6 to 8 months making it a poor choice for long term water stores. This is a cheap and simple process that you will want to add to your preparedness skill-set.

    @RayL661 First a reference: 68% or higher Calcium Hypochlorite is used during first of swim season shock treatment. Do not swim in this water after treatment for minimum of 24 hours, it will irritate your eyes and skin. 50% and lower Calc. Hypochlorite is for quick shock treatment of generally clean pool water and it is safe to enter the water after an application. As for sterilizing drinking water: If it is tap water you’ll be fine with 47%, but if it’s pond water go for the 68% or higher.

  2. I went and picked up some pool shock the other day but all they had was 47.6% Calcium Hypochlorite. I see yours has a higher percentage. I’m hoping I can use what I have, if so, do I have to adjust the ratio (like use more) to get the same results?

    @ss109guy Bleach has a shelf live of 6 months. This video is about LONG term water storage.

  4. Why this vs. bleach? Thanks.

    @ayres390 Your garage should be an adequate place at those temperatures, but protect your containers from direct sunlight and fill containers completely full removing any air space. Direct sunlight stimulates algae growth and if your chlorination may weaken some around the 12 to 18 month period thus you might see some green stuff on the sides of your tank. This is still in experimental stages for me as far as how long the chlorine treatment will last. I’ll keep you posted. Hope this helps. 🙂

  8. @okieprepper one more thing…does temperature matter… i mean do i need to store it at a specific temp. or can i store it in a garage. My garage is finished but it is not heated or cooled… i live in a climate that does hit 100 deg. and as low as 0 deg.
    i have not had the garage hit above 90 or below 35 deg.

    @ayres390 YES! Review the video again for safety sake! I know of a few people that have stored water in this fashion for over 30 months. When they tapped it for usage they could still smell the chlorine in the water. And that’s because the treated water was kept in an air tight container. As explained in the video chlorine escapes from the water as a gas once it’s exposed to ambient air. Keep your container in a cool environment and out of direct sunlight for best results. Hope this helps. 🙂

  10. question about the 3-4 hours sitting before drinking….if you have treated the water…say 6 months ago, do you still need to allow it to sit, or is this just for recently treated water?

  11. thanks again there alot of good people out …

    Excellent question and I didn’t cover that in the video becuause I couldn’t find any hard facts. But heres the general consensus. Chlorine escapes water as a gas so If your container is completely sealed up air tight and protected from direct sunlight it should last 18 to 24 months respectively. So if at anytime you open the lid on your tank and can smell the chlorine you should be good. If not then retreat the water before you get algae growth. Hope this helps.

    How long can the treated water be stored for? Example. A proper 50 gallon barrel sealed, treated and stored in the basement. Great video by the way Thank you.
