How to keep moisture out of inground pit with pumps to draw water?


My church uses well water for everything including fire suppression equipment. The control pump to regulate the amount of well water to be drawn for a large storage tank for fire suppression is located in an inground pit about 12 feet below surface. Dampness in the pit causes frequent rust and damage to the equipment. It has been suggested that we move the pump regulator and related equipment to the surface. Is there another option for controlling/eliminating the dampness in the pit?
