Basic Factory Built Dry Pit
Factory-Built Dry Pit
In a factory-built dry pit station, the pumps, valves, piping, and controls are factory installed inside a cylindrical steel chamber. The pumps are usually of the non-clog type. The motor is mounted on top of the pump. The pump chamber is delivered to the site as a prefabricated package and installed underground next to a separate wet well. A cylindrical tube is needed to provide access to the pump station from the ground surface. The access tube is connected to the pump chamber in the field. A portable engine-driven pump can be used as standby in case of a power failure.
