High efficiency toilet

A high efficiency toilet configuration, the toilet configuration comprising:

• a water tank including:
• a water supply line;
• a mechanical valve controlling a flow of water from the water supply line into the water tank;
• side walls and a tank base defining an internal volume of the water tank;
• a first through-hole in the tank base configured for channeling water out of the water tank;
• a tank outlet hole including a housing extending through the first through-hole in the tank base;
• a tank outlet valve configured for selectively prohibiting water in the water tank from flowing through the tank outlet hole and permitting water to flow through the tank outlet hole during a flush event;
• and
• a water column vessel disposed around the tank outlet hole and configured for separating water in the water tank between water outside of the water column vessel and a channel of water contained over the tank outlet hole;
• and
• a toilet base including:
• a bowl including a waste receiving basin;
• and
• a water supply plenum operable to receive water from the water tank and channel the water to the bowl;
• wherein the mechanical valve includes a float mechanism controlling activation and deactivation of the mechanical valve;
• and
• wherein the float mechanism is disposed within the water column vessel.
