When to stop borewell drilling?
Borewells are an essential source of water for millions of people around the world. However, drilling a borewell can be a challenging task, and it’s essential to know when to stop drilling to avoid wasting time and resources. In this article, we’ll discuss when to stop borewell drilling and the factors that influence this decision.
Geological conditions
The first and foremost factor that influences when to stop borewell drilling is the geological conditions of the area. The type of rock or soil present in the area can have a significant impact on the success of the borewell. For instance, if the area has hard rock or boulders, it may be difficult to drill beyond a certain depth. Similarly, if the soil is loose, it may not hold the casing in place, which can lead to collapse or failure of the borewell.
Water Level
Another crucial factor to consider when drilling a borewell is the water table level. The water table is the depth at which water is found below the ground surface. It is essential to drill deep enough to reach the water table, but not so deep that it becomes uneconomical. The water table level can vary depending on the location and season. During the rainy season, the water table may be higher, while in the summer, it may be lower.
Other Indications
The drilling process itself can also give clues as to when to stop borewell drilling. For instance, if the drilling rate slows down significantly, it may indicate that the borewell has reached a hard rock layer, which may be difficult to penetrate. Similarly, if the drill bit starts to wear out quickly, it may be a sign that it has reached a hard or abrasive layer.
The amount of water being pumped from the borewell can also give an indication of when to stop drilling. If the yield of the borewell is not sufficient to meet the water requirements of the area, it may be necessary to drill deeper or try a different location.

Conclusion
Drilling a borewell is a challenging task that requires careful consideration of several factors. It’s essential to know when to stop drilling to avoid wasting time and resources. The geological conditions of the area, water table level, drilling process, and yield of the borewell are all factors that influence this decision. By understanding these factors, you can make an informed decision on when to stop borewell drilling and ensure the success of your borewell.
