What color is used for Sewage/VCHT piping?

The correct answer is gold. In the context of industrial piping systems and marine engineering, color coding is a crucial aspect of identifying the purpose and contents of various pipes. Gold is designated for sewage and vacuum collection holding tank (VCHT) systems to ensure easy identification and to avoid dangerous situations that could arise from accidentally connecting or mishandling these pipes.

By using a standardized color code like gold for sewage piping, workers can quickly recognize the type of fluid being transported, which is vital for maintenance, emergency response, and operational safety. Such practices help in training personnel and minimizing risks on board vessels or in facilities where these systems exist.
