Wells are an important information to provide. But the Bing Imagery shows exactly what I was talking about before. If we look in the streets around, we see various water pools that could be left after heayv rain. 

To my point of view, we cannot conclude from this imagery that there is a well. I do not see a structure that would confirm a well in the midlle of the place. 

It is not easy to spot these from aerial imagery. For the Mali Activation, north of Mali early 2013, we could find wells with traces like a propeller around the well. This is done by using livestock moving around to lift the water out of the well.  Pierre

-Example of recently constructed well in Didieni/Mali (mounts of debris around, walls don't rise above (redundant redundancy) the ground):http://appropriateprojects.com/node/1022
-What seems new wells in Kayes, too (debris seen, walls not seen; seems square hole, possibly on the going of digging at the moment of satellite image):http://www.openstreetmap.org/edit?editor=id&%20#map=20/14.44191/-11.46058
