An improved pump device and control system for removal of liquid, such as viscous leachate, from a bore. A pump device includes a casing with an inlet check valve on a lower portion thereof and a discharge check valve on an upper portion thereof positioned within the casing. A fill cavity within the casing is connectable to a source of pressurized gas. As liquid/viscous leachate accumulates within the bore it enters the fill cavity through the inlet check valve. As pressurized gas is introduced to the fill cavity it displaces liquid/leachate from the fill cavity into and through a discharge tube and upward through the discharge check valve to remove the liquid/leachate from the fill cavity. The pump does not comprise a float. Control systems and devices provide for improved automated, semi-automated, and manual monitoring and control of pump device operation.
