What is the term for the connection between a safe and unsafe water supply?

The term that refers to the connection between a safe and unsafe water supply is known as a cross connection. This occurs when there is a direct link between potable (safe) water and non-potable (unsafe) water, which can lead to contamination of the safe water supply. Cross connections can occur in various scenarios, such as when hoses are submerged in contaminated water or when improperly designed plumbing allows for backflow from a potentially harmful source.

Understanding cross connections is crucial for maintaining public health and ensuring the safety of drinking water, as it helps water distribution professionals implement necessary safeguards to prevent contamination. This may involve measures such as backflow prevention devices, proper design of plumbing systems, and regular inspections to identify and eliminate any potential cross connections. Recognizing and managing these connections is essential for effective water distribution management and protecting consumer health.
