A drop manhole is a manhole in which a vertical pipe is provided to allow for flow between the branch sewer and the main sewer. It is utilized in areas where the slope is steep or when an inlet pipe's invert elevation is much higher than the outlet pipe's invert level.

the manhole is reduced from the size of the manhole riser to the diameter of a cast-iron manhole cover and frame. Special shallow cone sections, or flat cover slabs, are used for very shallow manholes. Large diameter manholes are covered with structural flat slab covers Circular Precast Concrete Manholes
