If you've wanted more information on the water well in Maramara, here is some info:
WHO DRILLS THE WELL?
The water drilling partner is International Aid Services (IAS) from Sweden. They are a Christian organization, but I don’t know much beyond that.
WHAT DOES IT TAKE TO DRILL THE WELL? HOW DO THEY DO IT?
Here is a photo of the same type of well that will be drilled in Maramara.
HOW MANY PEOPLE DOES IT TAKE, HOW IS IT DONE, AND HOW LONG DOES IT TAKE TO DRILL THE WELL?
Of all the pictures we've seen of the drilling process in Chad, we always see three guys from IAS, so I’m guessing that’s how many it takes. I’m not 100% sure about the process, but I can tell you what I understand to be the process. It begins with a survey of the community. This includes talking with the community to hear about the locations they would prefer to have a water well. It also includes looking for certain topographical features that often indicate water nearby. For example, I know they look for termite mounds as a sign of water. Also, I believe they do sonic testing of some kind (sort of like an ultrasound) to better understand where the water table may be.
Here is a great picture of girl from a village in eastern Chad drinking from their new well.
HOW DEEP DO THEY DRILL FOR THE WELL?
In Harako, the village where the pictures were taken, IAS drilled about 90 feet into the ground before they hit water. They were expecting somewhere between 100-150 feet, which is a more common depth in this area. Part of the expense of a water well is laying pipe as deep as you have to go. This can get expensive if you have to go really deep. Some water wells go 500 feet deep in some places.
HOW DO THEY TEST FOR WATER QUALITY?
After the water well is drilled, the team will take a water sample and test it. There are situations where drilled wells are not potable. I’ve seen water tests come back with high levels of Arsenic (at least too high to be safe), and I’ve seen water wells in coastal areas come back too saline. Neither of these situations are likely, but it can happen.
