"... for creating good reusable water systems?"

I'm not quite sure specifically your question. That sounds like a well or a stream to me. If you are bugging out or in the wilderness somewhere, Nature provides the tools for filtering water like this article.

Or a simple way of heating water using aluminum foil and the sun.

Then there's getting a gravity-powered water filtration system like this one. There is more to the website that might be of intererst.

I use armchairsurvival to purchase colloidal minerals, Lugol's iodine and other stuff. Kurt recently died, but his wife and son keep the business going. She's a wonderful lady too.

Lastly, depending on what your city code is, they tend to be 'fussy' about digging holes in the yard for water. Where I live it is all sand under a foot or so of soil. Not rocks whatsoever. I used a manual ice auger to hit the water table. I wanted to plant some well points in for watering the lawn, but the city was being pricks about it. It's a good thing they were not aware of the 30 foot deep hole I already made because I found out they would have forced me to pay a professional filling it in.

Besides that I can't think of anything else off-hand.
