What is manholes?

Manholes are access points that provide entry into the underground utility and infrastructure systems. They are typically cylindrical, covered with a heavy lid, and located at various points along roadways, sidewalks, and other areas of public and private property.

Manholes are installed for a variety of reasons, including providing access to underground pipelines for maintenance and repairs, allowing for the inspection of utility systems, and serving as ventilation points for underground facilities. They are also used as access points for stormwater and wastewater systems.

Manholes are commonly made of concrete, although some may be made of other materials such as brick or metal. The lids of manholes are typically made of cast iron or other durable materials, and they are designed to support the weight of traffic and pedestrians.

Maintenance of manholes is important to ensure their proper function. Over time, manhole lids can become damaged or deteriorate, and the surrounding areas may fill with debris or become clogged with sediment. For this reason, regular inspection and cleaning of manholes is recommended.
