I have always stored water in 5 gal Home Depot buckets for the hurricane warnings.how do you personally keep it safe to eat/drink? Too much conflicing info out there. Some say you can just store city water since it has chlorine in it, others say it still needs treated. And the amount of bleach to use is unclear.
I simply fill them with well water and add 3/4 teaspoon/3.7ml of 5-6% household bleach and snap on the black plastic lid they also sell. I did an experiment last summer and kept 1 bucket full for 3 months with no algae and I could still smell the chlorine in the water. It tasted exactly like freshly treated well water.
