ABSTRACT OF THE DISCLOSURE A pumping apparatus and method for pumping fluid using energy from rising and falling wave action in a body of fluid includes at least one float; a primary pump, such as a piston pump, connectable to the float for pumping fluid as the float rises with rising wave action; a secondary pump, such as a piston pump, connectable to the float and connec- table to a fluid container extending above the pumping apparatus; and at least one anchor connectable to at least one of the primary pump and the secondary pump for anchoring the primary pump and the secondary pump relative to the float. The primary pump is moved from a reloaded position to a discharged position as the float rises with rising wave action in order to pump fluid. The secondary pump pumps fluid into the fluid container as the float rises with rising wave action. The fluid pumped into the fluid con- tainer exerts a reloading pressure on the secondary pump in opposition to the buoyancy of the float which moves the secondary pump from an extended position to a retracted position as the float falls with falling wave action. The secondary pump is interconnected with the primary pump and moves the primary pump from the discharged position to the reloaded position as the float falls with falling wave action.
