Manholes - Model


Belowground sanitary and stormwater sewer piping require access openings by means of a manhole at certain intervals to allow for access, connection points, and change-in-direction points. The manhole is a belowground round or square structure made of precast concrete that allows sewer piping connections near the bottom of the manhole structure. At the street level, an iron access cover (often referred to as a “manhole cover”) is placed to permit access.

Stormwater manhole: This manhole is used on stormwater sewer lines for the conveyance of rainwater. The storm sewer manhole is generally characterized by a larger size, which is dictated by the sewer pipe connection sizes and orientations. Sizes of storm sewer manholes can range from 48” to 120” in diameter and will vary in depth according the depth of the storm sewer piping.
