I just got an email from the representative from Catholic Relief Services (CRS) who we traveled with when we visited projects in Ethiopia. One of the main focuses of CRS in Ethiopia is to bring clean water to villagers.
One of our visits was to a waterhole where hundreds of people were fetching water. The waterhole was disgusting yet it was all these people had. Anyway, the CRS rep. is back in Ethiopia and went back to the water hole. He reported that people are no longer drawing water from the water hole. About 30 yards away there is a new tap that provides clean, safe water to the villagers. An improvement like that makes it all worth it.
Below is a photo of the water hole that I took when I was there.
