Answer:
There could be a number of causes for a well to contain less and less water every year. A decline in the water table brought on by excessive use or drought circumstances, cracks or leaks in the well casing or pipes, or modifications to the local geological formations that affect the flow of water into the well are a few potential causes. It would be better to seek the advice of a specialist or well-informed person to evaluate the particular issue and pinpoint the root problem.
