These are shallow wells which draw water from a natural aquifer or man-made aquifer, e.g. near sand dam or around ponds, but which are not located inside a riverbed. It can include wells that are far from a river, or wells that receive water from shallow aquifers hydraulically connected to the river. Sometimes the holes dug are very large, allowing people and sometimes animals who are able to walk into the well to where the water is located. <br>Water extraction can be done with [[Handpumps]] or [[Small and efficient motor pumps]]. A bucket and rope can be used but risk of contamination increases. In such a case, household water treatment should be advocated.
