What is another common term for a manhole?

A manhole is commonly referred to as a "maintenance hole." This terminology highlights its primary function, which is to provide access for maintenance and inspection activities within underground utility systems, such as sewer and drainage systems. The term "maintenance hole" conveys the idea that the structure is designed specifically for the purpose of maintaining and servicing the utilities it houses, which can include tasks such as cleaning, repair, or monitoring of the infrastructure.

While other terms such as "access chamber" and "service hole" may also relate to access points for utility work, "maintenance hole" is widely recognized in the industry and aligns with standard terminology used in relevant regulations and guidelines. "Inspection well" typically refers to a structure designed for monitoring groundwater or other specific uses and may not encompass the broader maintenance functions associated with manholes. Thus, "maintenance hole" serves as an accurate and recognized synonym for a manhole in the context of utility maintenance.
