What is the color coding for pipes that carry potable water?

The color coding for pipes that carry potable water is blue. This standard is commonly used to ensure that individuals can easily identify which pipes contain drinking water, promoting safety and preventing contamination. Blue provides a clear visual cue that distinguishes potable water from other types of piping systems, such as those carrying wastewater or other fluids.

In plumbing and utility contexts, adhering to color codes helps workers and first responders make quick assessments during maintenance or emergencies. For example, if a pipe labeled with a blue color is damaged, it signals to personnel that it contains safe drinking water, which is crucial for both public health and safety.

Other color codes are allocated for different systems, such as green for sewer or wastewater systems, yellow for gas lines, and white typically for non-potable water, reinforcing the importance of accurate identification and awareness in building utilities management.
