They are commonly used in all wastewater management systems - from mainline sewers to the drainage surrounding roads and car parks. Opposite of, Benching - a smoothed concrete topping, usually a, Invert - the lowest point on the surface of a pipe, channel or culvert, Rocker Pipe - a short length of pipe, usually less than 1 metre, placed at the inlet/outlet of a solid structure, such as a manhole or building, to accommodate differential settlement between the structure and the drainage system. This can only be achieved by either breaking out the existing benching on the left-hand side of the idealised manhole to allow a new 'branch channel', sometimes called a 'slipper bend', to link the existing channel with the new pipe, or by breaking out a section of main channel and the benching to the left hand side and fitting an appropriate branch junction. This may be due to oversight when the drainage system was put in, or because the drainage system has not been updated to cope with subsequent developments.

The incoming pipe is projected through into the chamber, to enable rodding and cctv access, and then stoppered, as shown. Larger manhole chambers may be protected by a steel security grill. Instead of allowing a person to get down into the drain, they provide access for a drain rod, a water jetting hose, or a CCTV drainage survey camera, to assist in the process of inspecting, cleaning, or unblocking a drain pipe.
