Abstract
A septic tank filter system includes a tank. The tank includes an inlet and an outlet, wherein the outlet is disposed on the tank below the inlet to enable a flow of wastewater to be gravity fed from the inlet to the outlet. A filter is positioned in the tank. The filter includes a frame. A filter media is disposed on the frame. The filter media is operable to filter the wastewater of waste material as the wastewater passes therethrough. A top opening is disposed on a top portion of the frame. A bottom of the top opening is located above the tank outlet and below the tank inlet. When the filter media is not clogged, a level of the wastewater remains below the top opening. When the filter media is clogged, the level of the wastewater rises until the wastewater flows over the top opening.
