Having many ways to have clean water is a MUST!
Have a water filter system and other ways to use in an emergency.
I Made my own system from watching a Youtube video. Just used 2 buckets and a Berkey Water System Replacement Filters. Not too hard. I bought some silver spray paint thinking that I would paint them to make them kind of look better, but I like the buckets as they are - they have measurements down the sides.
