What is cross-connection in the context of irrigation systems?

Cross-connection in the context of irrigation systems refers to the situation where potable (drinkable) water is unintentionally mixed with non-potable water sources, such as irrigation runoff, stagnant water, or other contaminants. This can create serious health risks, as contaminants can enter the potable water supply, leading to potential diseases or health issues for individuals consuming that water.

Recognizing and preventing cross-connections is crucial in the design and maintenance of irrigation systems. Proper backflow prevention measures, such as backflow preventers and air gaps, are essential to safeguard clean water supplies from becoming contaminated. This understanding emphasizes the importance of keeping irrigation systems well-designed and maintained to protect public health and ensure safe water usage.
