The waste liquid collection and transfer system includes at least one waste liquid transfer vessel that has a liquid input valve and a liquid output valve for controlling the flow of waste liquid therethrough. A pressurized gas liquid transfer system including at least one control valve is utilized to provide pressurized gas to said vessel to control the flow of liquid therefrom. A liquid drain line is engaged from the vessel to a liquid collection tank, and a liquid level alarm device is engaged to the tank to provide an alarm if the level in the tank becomes too high. An electronic system controller is engaged to the alarm device and to the various valves to control the flow of liquid throughout the system. When an alarm signal is received by the system controller the vessels are first emptied and thereafter allowed to become full, acting in this instance as additional waste liquid storage containers. When the vessels are full, the system controller shuts down the flow of liquid to the vessels. When the flow of liquid to the vessels is shut down by the system controller, it may then become necessary to shut down the chemical process equipment that generates the waste liquid.
