I filled (2) 48 gallon plastic drums with water today.
I purchased these from Coke $10 each.
I treated each with 1/4 cup bleach (6%).
IF NEEDED, I will siphon water out into a bucket, pour back and forth into second bucket to "mix air into water", then send though a activated carbon filter and drink.
If the tap water still works when I move out, I will empty without drinking.
This will supply my family of 5 drinking water for 3 weeks without the Tap.
