Hand Dug Water Well and Public Space

Dig a well, then create a cooled public space.
  [vote for,

First get four guys (pablo, felix, mario?, manuel? hard to read the t-shirts) to dig a village well as shown in the video. A several weeks work it looks like, if not more.

Notice how once they get down to the water table they build A cylinder of masonry to keep the rain and mud out of the water supply. So the idea is:

Build a building around this cylinder and dig the floor down from street level. This dug out area can be cooled using some water from the well similar to a swamp cooler. A fan might be required, but with careful design the fan might not be needed. This would even work if the well water was salty and not potable. A knee high wall to keep very hot air next to sand/dirt out of the building and maybe a walled in courtyard would be advisable.

Public or private; A central building in a village that stays cool in the desert environs would have value.

       Swamp coolers are most effective in low-humidity environments. You don't want to do this if the village is located in a jungle.

       Another gotcha is the sewers. Both for rain water and sewage. All flow has to be far away from the well and nothing that will leak.   

       The building I now have in mind is a sort of half buried doughnut with a thatch roof. And large beer signs.
