You know bleach to make safe drinking water, but bleach only has a shelf life of about 6 months. You can use the active ingredient from bleach and disinfect water with Calcium Hypochlorite.
Disinfect Water with Calcium Hypochlorite
Boiling your water is the easiest way to make it safe. Bleach (ONLY Calcium Hypochlorite bleach) can also be used to make safe drinking water, but bleach has a shelf life of that is less than 2 years.
You can use the active ingredient from bleach and disinfect water with Calcium Hypochlorite.
We’ll use the dry Calcium hypochlorite to make our own bleach solution, to purify water. Once you add water to the Calcium hypochlorite the clock is ticking on it’s effective life-span, just like regular bleach. Store the granules dry for long-term storage.
Making the Chlorine Bleach Solution
First we need to make our bleach solution. This bleach solution is NOT drinkable, we are using it to treat the water we do want to drink. DO NOT DRINK THE ORIGINAL Chlorine (BLEACH) SOLUTION!
Create the Chlorine (Bleach) Solution (used to treat the drinking water…not for drinking directly)
- To make a stock of chlorine solution (do not drink this!) dissolve 1 heaping teaspoon (about one-quarter of an ounce) of high-test (78%) granular calcium hypochlorite for each two gallons (eight liters) of water.
Disinfecting Water for DRINKING
- To disinfect water add one part of the chlorine solution to 100 parts water to be treated.
- Let the mixture sit for at least one-half hour before drinking.
- To remove any objectionable chlorine odor, aerate the water
If the water is cloudy with suspended particles:
- First filter the water as best you can (a t-shirt, bandana, shemagh or other fabric will work)
- Double the amount of bleach you add to the water.
- Stir it well.
- Let the mixture stand for a half hour before drinking.
A one lb. bag of this stuff will make around 128 gallons of bleach, which should allow you to treat about 12800 gallons of water (1:100 ratio). 10,000 gallons of drinking water, is roughly enough for a family of four for six or seven years at a gallon per day per person!
Do not mix the dry granular calcium hypochlorite until you are ready to treat water, since once it is made into a liquid solution it will begin to degrade and will eventually become useless as a disinfecting agent. This also means you should make your treated drinking water in small batches, for example enough for a few weeks at a time at most.
When selecting your calcium hypochlorite, ensure that it does NOT contain any water clarifiers or anti-algea agents.
A bonus for using calcium hypochlorite to disinfect water, is that a little goes a very long way. A 1-pound bag of calcium hypochlorite in granular form typically costs only a few US dollars and can be obtained on Amazon.com, or at your local pool supply company. This amount will treat up to 10,000 gallons of drinking water, which is enough for a family of four for between 7 to 7 years, at a gallon per day per person!
As always verify the products and measurements to be sure this info is safe and correct. I take no responsibility if you can’t measure properly, buy the wrong product or just screw this up. Your life is yours, so do your homework! When done properly you can safely Disinfect Water with Calcium Hypochlorite.
