A manhole is a small, usually circular opening in the ground that provides access to underground utilities such as sewer systems, electrical lines, or water pipes. It is typically covered by a heavy lid made of metal, which can be removed by workers to perform maintenance or repairs. Manholes are commonly found in streets or sidewalks to allow for easy access to these systems without digging up large sections of the surface.
