Which color is used for indicating sewage?

The correct color for indicating sewage is black. In color coding systems, black is typically associated with sewage and wastewater management. This choice ensures clarity and safety when dealing with hazardous substances, as workers and individuals can easily identify pipelines or areas that carry sewage, thus taking appropriate precautions.

The use of black for sewage helps to prevent confusion with other types of waste or water systems, such as stormwater drainage or potable water, which use different colors according to industry standards. Proper color coding is crucial in various fields, including construction, plumbing, and environmental safety, to maintain hygiene and prevent cross-contamination.

While gold does have its specific uses in certain contexts, it is not standardized for sewage in the widely accepted color coding systems.
