Which color band designates ROWPU piping that carries filtered water?

In water and fuel systems maintenance, the color coding of piping is crucial for ensuring safety and clarity in the identification of different types of fluids carried in the pipes. The color band that designates ROWPU (Reverse Osmosis Water Purification Unit) piping specifically for filtered water is yellow.

Yellow is a standardized color in many systems to indicate that the pipeline carries treated or filtered water, distinguishing it from other types of water systems that may convey raw or untreated water, chemicals, or waste. Understanding this color coding helps operators to quickly identify the purpose of a pipe at a glance, facilitating proper handling and preventing potential cross-contamination or errors in operations. This knowledge is vital for maintaining operational efficiency and safety in water management operations.
