What is the purpose of an air line of a well?

The purpose of an air line in a well is primarily to determine water levels within the well. This is achieved by using the air line to reference the level of water above a certain point in the well. By introducing air into the well through this line, it can create pressure changes that help to gauge the water level accurately.

In practice, an air line is connected to a measurement device, such as a pressure transducer, which can convert the pressure readings into a water level measurement. This method is particularly useful for continuous monitoring of water levels, allowing operators to optimize well performance and manage water resources effectively.

Understanding this function emphasizes the importance of accurately assessing water levels for operational and regulatory compliance within surface water management practices.
