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.
