Often, a small place is more welcoming to life. You have an excellent attitude toward living, and I congratulate you for that.
Drinking water is very valuable. In my area, we receive water for only one day every four weeks, that's the approximate time. It could be a week more or a week less.
So, we carefully measure how much water is used for each purpose, as you tell us: you know the value of water when you have to carry your own water.
Living on the boat forces me to be more environmentally conscious overall.
It's frightening when you hear of such cases. However, I experienced water shortage when I lived in the Philippines, and I observed that locals worked their schedules around it.
I applaud you on your water management:)
