What is the primary purpose of a Cross Connection Control Device?

The primary purpose of a Cross Connection Control Device is to prevent contaminants from entering the water supply. These devices are crucial in maintaining the safety and integrity of drinking water systems by ensuring that water does not flow backward from potentially contaminated sources into the clean water supply. Cross connections can occur when there's a direct linkage between the potable water system and a non-potable water source, leading to a risk of contamination due to backflow or back siphonage.

By incorporating these protective devices into a water distribution system, operators can effectively mitigate risks associated with cross connections, thereby safeguarding public health and ensuring that the water supplied to consumers remains free from harmful substances. This function is integral to compliance with safety regulations and standards in water quality management.
