Well drilling is the process of creating a hole in the ground to access underground water or other resources. This is typically done using specialized equipment that can penetrate various types of soil and rock. The depth and diameter of the well depend on the specific needs and geological conditions of the area. Once the well is drilled, it may be lined with a casing to prevent collapse and contamination. Water is then pumped to the surface for use in homes, agriculture, or industry. Proper well drilling ensures a reliable water supply and is essential for sustainable resource management.
