What does a decrease in gallons pumped per kilowatt hour used indicate?

A decrease in gallons pumped per kilowatt hour used signifies a reduction in the efficiency of the well system. This metric reflects how effectively the energy consumed by the pump translates into water being delivered. When this ratio decreases, it indicates that more energy is being used to pump a lesser amount of water, which typically points to problems such as equipment wear, blockages, or mechanical failures that impede performance.

In contrast, optimal performance and improvements in energy efficiency would be characterized by higher ratios, meaning more gallons would be pumped for the same amount of energy consumption. Therefore, a decline in this metric serves as a clear indicator that the well's operational efficiency is not meeting expected standards, likely due to decreased efficiency within the well itself.
