Out here the wells run deep 700 feet is quite common. We've got to get past the mine shafts for good water. The ranchers have windmills all over.
It's a good flow and fills large cattle tanks. They simply disengage the windmill if they don't want it running all the time or want to shut it
down. They work really good in spite of the depth.
We were on a trickle feed pumped from a spring. 9 homes could fill their cisterns overnight using this method. We all have cisterns for storage. When
the power goes out my house pump doesn't work so no house pressure but I can get water out of the cistern quite easily. In addition we have mobile
tanks that can hold 800 gallons along with our 1200 gallon cistern we would have enough water for emergency use for quite some time. We also have a
250 gallon hot tub.
Some neighbors have their own well. They pump this water into a cistern for home use. They have a low flow well and this method seems to work best for
them. Before they were having to wait for the well to recover before they could pump more and had to restrict their usage considerably. They hauled
water from town that first time to fill the cistern then the well was able to keep up with their daily usage. Many people around here with wells use
cisterns for storage.
I feel better having that large amount of water on hand. I would think the wind mill for deep wells would work just fine. The hand pump, idk. You
might check out the cost of putting in a cistern to be fed by your well keeping it full for emergencies. I think windmills might be pretty costly to
buy or build. It would have to be stout to stand up to strong winds Idk about the weight of the pump it has to support but the windmills here are
welded steel, pretty hefty solid structures.
