What are the Differences between a Manhole and an Inspection Chamber?

In construction and other areas of public and underground works, access structures have a critical function for the servicing and inspection of sewers, drainage, and utility lines. One of the two frequent components for this purpose is named Manhole and Inspection Chamber. Both components are different in dimensions, design, functionality, and form, yet they serve the same purpose of providing access to an underground drainage system. Each set of differences, standalone, serves a purpose which is useful for civil engineers, utility planners, and developers. 

Some of the crucial foundries which manufacture these components are Govind Steel Company, which is one of the top producers of grey iron and ductile iron castings in the country. Let’s analyse the differences between inspection chambers and manholes, along with their respective use cases.

Differences Between Manhole and an Inspection Chamber

Purpose 

  • Manhole refers to a vertical access point, which is built in underground drainage and utility systems. This has been designed for people to enter to clean, inspect, maintain and repair work, and are commonly found on footpaths, city roads and industrial complexes. 
  • On the other hand, an inspection chamber is a small access point that permits visual inspection and cleaning for equipment but entering physically is not possible. This is usually used in light-duty or residential drainage systems to inspect flow direction and junctions. 

Depth and Size 

  • Manholes are larger in size so that people can pass and thus are installed at greater depths based on the complexity of the network. 
  • Inspection chambers are shallower, less than 1 meter deep with smaller openings. 

Construction Materials 

Components with ductile iron covers or cast iron at Govind Steel specialises in presenting durable chamber covers and manhole covers and ensure to meet the international standards. However, the covers vary in load-bearing capacity based on the place they are installed like heavy traffic rods, residential driveways or pedestrian areas. 

Applications 

  • Manhole covers are put in municipal sewer systems, utility tunnels and telecom values, which are spaced at regular intervals or put at pipe junctions and changes in direction. 
  • Inspection chambers are best fit for private residential drainage like inspection connections from bathrooms or kitchens to the main sewer line. These are put where maintenance is not required frequently. 

Maintenance and Accessibility 

  • Manholes are manually accessible, which makes these crucial for maintenance teams to enter the system and conduct inspections. 
  • In case of inspection chambers, it can be accessed through cameras as it does not support human entrance and is used for cleaning roads and jetting equipment.
