AWWA ACE54503

Deep set pumps often cause well water problems. Typical problems associated with a deep pump setting are rock falls, sand, grit, mud, bacteria, and biofouling. These water well problems may be the result of excessive storage and affect water quality. Unused water stored up in wells rapidly grows slimey. A deeply set pump creates excess storage and unnecessary oxidation inside the well. Pumping depth controls the amount of storage and degree of aeration within the borehole. Correct depth is a critical factor to the continued production of clean water within a well. Wells with sound construction can develop problems when the pump is set too deep. Wells under the influence of surface water easily develop thick biofilms that change the taste, smell, and color of the water. No matter whether a well has sound construction or problems from the start, stale enriched water should be eliminated from storage. Adjusting the pumping rates and depth of the pump, inserting a recirculation loop, or installing a sleeve are methods to decrease the storage held and refresh water within a well. Stored water damages water quality when it is not renewed regularly. Setting the pump at its optimum depth works to prevent well problems by eliminating excess storage.
