The exit weir tank acts as a passage to either the waste line or the distribution tank. Depending on the quality of the treated water and the functionality of the plant, one of the two passage ways is plugged to prevent the water from traveling down that pipe.

The dimensions of the exit channel weir tank are identical to those of the inlet channel weir tank.
