Cross Connection Control
A cross connection is any real or potential connection between the water supply and a source that can contaminate or pollute that water.
When the system experiences a loss in water pressure, such as when a fire hydrant is opened or a water main breaks, a backflow can occur that causes water in the pipes to flow in the opposite direction. That's when a contaminant or pollutant could travel into drinking water.
Common cross connections include:
- Commercial properties, from carbonated beverage machines and ice-makers, fire sprinkler systems and x-ray machines.
- Residential properties, with lawn irrigation, fire sprinkler systems and even a common garden hose, when submerged in water.
