A manhole (alternatively utility hole, maintenance hole, inspection chamber or access chamber) is the top opening to an underground utility vault used to house an access point for making connections or performing maintenance on underground and buried public utility and other services. Manhole is protected by a manhole cover, also known as a 'biscuit', a plug designed to prevent accidental or unauthorized access to the manhole.
