What is the standard color code for marking water pipelines?

The standard color code for marking water pipelines is blue. This color is specifically designated for conveying water lines, which helps ensure that workers, engineers, and emergency responders can easily identify the type of utility pipe when conducting maintenance, construction, or emergency operations.

Using blue for water pipelines maintains consistency across states and regions, facilitating safety and reducing the risk of accidental damage or disruption to the water supply. This color coding system is part of a broader initiative to promote awareness and safety around underground utilities, offering clear visual guidance on the type of service an underground line provides.

In contrast, red is typically reserved for marking electric power lines, yellow for gas lines, and green for sewer lines. Understanding these color codes is crucial for anyone working in or around utilities, as it promotes proper identification and helps prevent hazardous situations.
