Water

I've read 7 articles about water prepping lately and though I have learned a few things, I seriously disagree with the useage/ storage amounts. So this week I will keep track of all my water each day, temps will be in the high 80's To mid 90's so my water consumption should be in the average range and yes I will shower daily. If we R to believe the experts, we need 100 Galen's a day per person. Show me how to quire that at a Bugout location without electricity. I have a composting toilet and a rainwater system, I also have access to a river/lake.
