What is the function of a gravel tube?

The function of a gravel tube is to observe the level of gravel in the well. Gravel tubes are typically installed in water wells to provide a means of monitoring the depth of gravel or aggregate material that is used for filtration and support around the well's screen. This monitoring is crucial because it helps determine the effectiveness of the well in preventing sediment and ensuring that the water being pumped is clean and free of particulate matter.

Understanding the gravel level is important for operational efficiency and water quality maintenance, as it can indicate changes in water flow or potential clogging within the well structure. Monitoring this aspect helps in making informed decisions about maintenance or any necessary interventions to ensure optimal well performance.
