No Well Water Collection.

The emergency water scenario I am choosing is in a mountain environment because I have lived for the last 20 years and am comfortable. The most straightforward setup for water collection is a location on a south-facing slope that is 1/2 to 3/4 the way up the mountain to gain water pressure through gravity and pipe reduction. Ideally, the top is a Plato usable for planting a small garden and a possible wind turbine. Then down from that, a pole barn where the shed roof is metal and used to collect water that funnels down the hill into a storage tank. The shed is also covered in metal, which can collect condensation at dew points and direct the water into the storage tank. This tank will have three places for water to go. The bottom is the cold water that runs to the cabin. In the middle is water that has stratified with heat and is a little warmer, and it will go out about 3/4 of the way up to a couple of black barrels to be heated further for hot water. The third outlet is at the top of the storage tank, and the overflow runs to a lower-elevation pond than the cabin. This way, the water system does not need to be maintained when no one is staying at the place and can be used when required. The pond can house fish that can be eaten, and the runoff water filtered through mushrooms brings in-game that can be hunted. This is an ideal place to grow water plants like duckweed that can be harvested to feed livestock like chickens. This is a well-designed water system for a remote self-sustaining cabin in the woods.
