What is a manhole?

A manhole is a covered opening in a street or sidewalk, typically used for maintenance and access to underground utilities such as sewage, water, electricity, and telecommunications. Manholes are usually made from durable materials such as concrete, metal, or fiberglass to withstand heavy traffic and weather conditions.

Manholes are often circular or rectangular in shape and are secured with a heavy cover that can be opened or removed for maintenance purposes. They are essential for allowing workers to access and inspect underground infrastructure, as well as providing ventilation for underground spaces.

Manholes are typically marked with a logo or symbol indicating the type of utility they provide access to. They play a crucial role in maintaining and repairing underground infrastructure, ensuring the smooth operation of essential services for communities.
