The complexity of the pumps is a fundamental problem for all programs of this kind, as well as the quality of the pumps given the heavy demands of a village. [20] A 1994 study, also Bank funded, of the endurance of hand pumps in Africa showed that only 41 to 51 percent of hand pumps were still functioning. [20]
