How long does a well last?

The well should last indefinitely if it was constructed properly with quality materials.  There are times when a well may need to be re-developed to clean out sedimentation that may be blocking the flow of water.   The pump, on the other hand, will need regular maintenance and replacement parts depending on the amount of use and the quality of the materials.  Lifetimes of five to 10 years can be expected for hand pumps.   It is estimated that in Africa, approximately 50% of the pumps are not in service due to disrepair, but the well may still be good.  In these case, pump replacement is all that Is needed with a commitment from the community to keep up with maintenance by paying for the water.
