A nasty combination of fat, wet wipes, condoms and nappies is clogging Brisbane's sewers.

Residents are responsible for these blockages as they pour cooking oils down kitchen sinks and flush items such as wet wipes, creating so-called "fatbergs".

Queensland Urban Utilities has captured footage of fatbergs across the city including at Buckingham Street, Ashgrove, Montague Road, West End, and Sir Fred Schonell Drive at St Lucia.

A camera placed into the sewer network showed sizeable fatbergs covering the pipes, obstructing the flow of water.
