1. A pumping system comprising:
an inlet conduit;
a chamber assembly in fluid communication with the inlet conduit; and
a buoy assembly removably coupleable to an end of the inlet conduit and configured to be deployed in a flooded shaft for removal of debris and liquid therefrom, the buoy assembly comprising a buoy configured to float on a liquid surface and having one or more aeration ports selectively opened to allow airflow therethrough from outside the buoy to inside the buoy to facilitate lifting of liquid and debris along the inlet conduit toward the chamber assembly; and
one or more baffles in the chamber assembly and one or more sensors that extend into a chamber of the chamber assembly, the baffles configured to direct liquid flowing through the chamber assembly toward the one or more sensors.
