  • a pump capable of moving water and contaminant from below ground surface to a location above ground surface;

    a motor connected to drive the pump;

    means connected to power the motor;

    a water and contaminant inlet located between the pump and the motor to accept inward flow of water and contaminant to the pump;

    an outlet pipe connected to the pump and extending above ground surface; and

    a sleeve surrounding the inlet and connected between the inlet and the motor and having an opening to receive water and contaminant at one or more points along the outlet pipe, the sleeve being sized to slide in and out of the well and larger than the outlet pipe and creating an annular space to permit passage of water and contaminant from the opening to the inlet.
