Question: 1 / 400

What color must all reclaimed water piping be?

Red

Green

Black

Purple

The requirement for reclaimed water piping to be purple is based on national standards to promote safety and prevent cross-contamination with potable water sources. The purple color serves as a clear and recognizable identifier for non-potable water, specifically reclaimed water that is treated and reused. This distinct marking helps ensure that people can easily differentiate it from drinking water pipes, thereby minimizing the risk of accidental misuse or exposure. By using a standardized color, operators, maintenance personnel, and the general public can recognize and react appropriately to the reclaimed water system. This consistency in labeling is essential for safe and efficient water management practices.
