As a Peace Corps Response Volunteer, I'm working on a water/sanitation project based out of the town of Beloha. Our team recently visited the village of Ambondro to fix a pump. Because there was no filter in the bottom of the well casing, sand entered, clogged the piston, and eventually broke it. The whole system needed to be removed to make the repairs.We brought some tools and materials with us: about 15 meters of PVC pipe to bail out the well, handsaws and wrenches, and some geo-textile for the filter. However, getting all the parts to fit and work together required a bit of improvisation.
First, My co-workers Amede and Christian bailed excess water out of the well to make it easier to pull out the well casing.
Then, six of us used most of our muscles and three monkey wrenches to pull 12 meters of metal casing, in four sections, out of the well.We finally pulled out the entire length of casing and the pump column inside it, and replaced the broken piston. After testing the parts together it was clear that we needed a lubricant between the piston and the well casing.

Goat lard was suggested. However, Josoa, the president of the water committee, pointed out that some of the residents of Ambondro are originally from the southeastern region of Anosy. It's taboo for them to consume any part of a goat. So instead, we coated the parts with zebu lard, which is universally acceptable for the Malagasy.
Finally, we wrapped some geo-textile as tightly as possible around the base of the casing to serve as a a sand filter. However, when we tested it, the overly-picky filter kept water out of the well too!It was starting to get dark and we didn't have any other filter material with us, so we had to return all of the heavy casing into the well in a different broken state. Next week we'll return with bronze mesh, and hopefully be able to leave town with our chins a little higher.
