Culvert, screen and outfall manual, (CIRIA C786) published by CIRIA in 2019, defines a conduit as: ‘A channel or pipe for conveying water or other fluid. A culvert would normally be a buried conduit and a channel an open channel conduit.’

The word conduit may also refer to electrical conduits, which are tubes or pipes used to protect and route electrical wiring as it passes around buildings or other structures. This is generally made from either metal or plastic, and may be rigid or flexible.

Firestopping of service penetrations, Best practice in design and installation, published by FIS (Finishes and Interiors Sector) in 2020, defines a conduit as: ‘A metal or plastic casing designed to accommodate cables, normally circular in section.’
