Inspection chamber are integral part of the drainage system providing an access point to an underground utility service. Just because of this access point it is easy to test, inspect, clean, repair and unblock the underground drainage systems.

The building regulation of UK governs the guidance on inspection, design, structure and location of the manhole. Manhole chambers are located at one of below in the drainage system 

  • At a point where main drainage pipe and branch drainage pipe joins
  • When the piping is for more than 22 meters straight
  • When the direction of sewer pipe or drain changes more than 30 degrees horizontally
  • When the size of the pipe changes 

Manhole chambers are temporary storage point for water as these chambers allows water to build up in the system rather than flood out straight away. 

MAC (mini access chambers) is an innovative and cost-effective solution for access to the drainage system. MAC can be used to an invert depth of 600 mm. 

The depth of the inspection chamber can be increased to 3m when used with a restricted access cover. Side risers as shown in the image above are used to increase the height of the inspection chamber, these side risers can be cut down to sizes required to get a more accurate height. 

It is advised to install inspection chambers on a suitable bed depending on the quality of the trench and the backfill material.
