How must non-potable irrigation water be identified?

Non-potable irrigation water must be identified to prevent accidental human consumption and to ensure safety when water is being used for irrigation or other non-drinking purposes. Using a metal tag is an effective method for this identification, as metal tags are durable and resistant to environmental factors, ensuring that the identification remains intact and legible over time. This is crucial in preventing serious health risks associated with the misuse of non-potable water.

The requirement for marking the water is also supported by regulations and standards in plumbing and irrigation practices. Such identification helps users easily recognize the water source and ensures compliance with public health codes. Choosing a robust method like a metal tag reinforces safety practices, reminding users of the nature of the water they are dealing with. This is crucial in settings where incorrect use can lead to contamination or health hazards. Thus, the identification of non-potable water with a metal tag aligns with best practices and regulatory compliance efforts in irrigation systems.
