Just came back Yesterday evening from surveying a water project in a Lahu village. The existing piping doesn’t produce enough water anymore. In this particular village I did my first project nearly seven years ago. So we ventured into the mountains and worked our way through the jungle. I took the surveying instruments along, but were unable to use it because of the density of the forest. We had to go down into a deep ravine. Also my altitude meter didn’t work. I don’t know why. I used then my Swiss pocket knife that has an altitude meter. With this I measured the difference in altitude going back all the way back to the village. The distance we counted in paces and later measured the passes with a tape measure and so got the  distance. Once again I wished to have an GPS.
So now back in Chiang Mai I need to calculate the costs and think of how to do the water collection. Then we have to try to get the funds together. My first estimate without the tanks is about 30’000 Thai Baht. What we found is that it is actually possible to put the pipe through the mountains even though the area is very difficult.
