How to construct a shallow manhole

Most underground services need to be accessed to carry out repair and maintenance works. They can be accessed through manholes, which consist of a vertical shaft allowing a person to get into a chamber below ground level. The type and size of manhole depends on the type of action required for repair and maintenance works to the service. Each entity has its own requirements for its own manhole.

Manholes can be divided into two categories:

  • Series 1500 Manholes for motorway communication ducts.
  • Series 500 Manholes for sewer and storm water networks, including catch pits, inspection chambers and draw pits.
In this post, the latter manhole will be described.
