This agricultural well was not producing expected and necessary volumes of water. Shannon Pump pulled the pump, and WellJet went to work. Following WellJet, the same pump was immediately reinstalled.
The results were unbelievable: production increased more than 350%, specific capacity more than quadrupled, overall pump efficiency more than doubled – and the cost to pump water decreased by more than 60%!
