Yes, water is a concern. We had a well and I think we could get it up and running again. The problem is making sure water is pure. We also have a creek. So, water is not a problem. CLEAN water is the problem. I don’t know how to make it clean.
We live on some acreage with more wood falling to the ground than we can manage to turn into firewood. With this in mind, I bought a Stovetec "rocket stove" and a water pasteurizer from the same company.
We heat our house with a wood stove but I was afraid that we would go through too much wood if we became dependent on it for all our needs.
The "rocket stove" was developed to reduce the fuel needs in third world countries. It is lined with insulating material and configured to maximize the heat obtained from the fuel.
There should be Youtube videos describing the product and its uses and benefits.

or make your own.
Some people install the filter through both the bottom of the top bucket plus the lid for the bottom bucket which attaches the two of them together. (same size hole for both pcs)
Some people just install the filter in the bottom of the top bucket and drill an oversized hole in the lid to the bottom bucket and then set the top bucket on top of the bottom with the filter outlet tube passing through the oversized hole. Either way works.
Lots of youtube vids showing how to do this.
I use a Uni-Bit aka stepped bit for drilling the holes. Holes saws, spade bits works too. Even auger bits. Uni-bit is the smoothest but they're not cheap. I already had one.
