What is the definition of 'cross-connection' in water supply systems?

• A. A point where chemicals are added to potable water
• B. A point where stormwater enters wastewater systems
• C. A point where non-potable water can mix with potable water
• D. A point where water is treated for purification

Answer: (C)

The definition of 'cross-connection' in water supply systems refers to a point where non-potable water can mix with potable water. This is a critical concept in maintaining water quality and preventing contamination. Cross-connections pose a significant public health risk because if non-potable water, which may contain harmful contaminants or pollutants, mixes with the safe drinking water supply, it can lead to the disease transmission and other health issues. Preventing cross-connections is an essential part of plumbing and water supply system design, often requiring specific backflow prevention devices to ensure that potable water remains uncontaminated. Understanding cross-connections helps water operators implement effective measures to protect public health and maintain the integrity of the water supply system.
