What is an indicator of a well's declining productivity?

A consistent reduction in flow rate during water extraction serves as a key indicator of a well's declining productivity because it reflects changes in the aquifer's ability to supply water. When a well experiences a steady decrease in flow rate, it may suggest that the water table is dropping, the surrounding aquifer is being depleted, or there could be increased sedimentation or clogging in the well itself. This reduction can lead to significant issues such as insufficient water supply for the intended uses, requiring more frequent checks or interventions.

In contrast, increased water clarity typically indicates good water quality rather than a reduction in productivity. Stable water pressure suggests that the well is functioning normally and that the aquifer is maintaining its supply, which does not signal a decline. Regular maintenance checks are crucial for ensuring the well operates effectively but do not directly indicate changes in productivity unless linked to a noted decline in performance.
