Manholes (alternatively personholes, utility holes, maintenance holes, or sewer holes) are generally found in urban areas, in streets and occasionally under sidewalks. A manhole is an opening to a confined space, allowing maintenance workers to reach underground public utilities like sewers, storm drains, gas pipelines, etc. Manholes are required so that workers can inspect, maintain and upgrade these units. Manholes are always companied by manhole covers as the covers prevent people from falling into manholes.
Over the years, the construction of the manhole covers has changed. Here's a brief introduction of the manhole cover manufacturing process.
