Low-Cost Water Well that also Monitors Water Level

There seems to be interest in low-cost methods of making a dual-use water well. This well would supply drinking water and also monitor the water level below ground.

Here are some links that might be helpful to those especially in developing countries....

http://en.wikipedia.org/wiki/Water_well - basics laid out here...also mentions "....a well constructed for pumping groundwater can be used passively as a monitoring well and a small diameter well can be pumped, but this distinction by use is common."
