Equations have been derived using rigid-water-column theory which permit rapid assessment of pressure surge magnitude owing to rejoinder of water columns in pump-discharge lines subsequent to a water-column separation induced by failure of power to the pump drivers. The method is valid only for systems which are equipped with check valves at the pumps.
