A manhole is an access point to a subterranean utility vault or chamber, typically found in urban areas. Manholes are used to house and protect various utility connections, such as sewer and water lines, electrical and telecommunications cables, and gas lines.
They are typically circular in shape and are constructed of reinforced concrete or other durable materials. Manholes typically have a removable cover or lid that is used to gain access to the utility connections inside.
The detail of a manhole can vary depending on the specific use and location, but generally includes a frame and cover, a riser, and a base or invert.
