This particular site is for returning refugees. People who have basically been forced to return from Iran, Pakistan, India, and other places. If they are unhappy to have been placed in the middle of nowhere, to a place with zero current opportunities for livelihood, it makes them even less happy that they are to live such a different quality of life than they had in the countries they are returning from. What they want is electricity, lights for studying and the possibility of working into the evening, radios, televisions, etc. My project didn't start from the problem of how to pump water, but from how to provide electricity to rural villages. Any solution needs to be made sustainable by making it such that Afghans can provide it and maintain it for themselves. From my perspective, importing anything is done with reservation. On these wind turbines, the only part directly imported are the magnets. Everything else is available somewhere in the city.

Another advantage to the multiple dc pump route is that they can each be switched on and off depending on demand. Excess power being produced by the wind turbines can be diverted from pumping water to powering the battery bank (for lighting, etc).

So, based on your availability statement why can't people in the city build the components needed for a wind powered, mechanically coupled, rod activated suction pump? Then you don't even need to import the magnets. A neighbor of mine has had a rod type pump working at 300 feet for as long as I can remember, over half a century. Now, we're coming to the crux of the issue. What can the locals do themselves. Considering the level of the technology involved and your statements, I see no reason why they couldn't build the complete pump of the type I described.
