Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

The average lifespan for a well is 30–50 years. 2. How deep is the well? Drilled wells typically go down 100 feet or more.

Water levels can run low again in winter if your area experiences freezing temperatures. Water levels rise again in later winter as melting snow contributes to the aquifer. In spring and summer, plants will use up the water as they grow. Your area might be different.
