Only one working sewer gas destructor lamp remains in London; however, due to a traffic accident, the original lamp was damaged and has been replaced with a replica.

This lamp is currently in use and can be found burning day and night down the side street of the Savoy Hotel in London. The story of this lamp has given rise to locals referring to Carting Lane as 'Farting Lane'.
