Backflow Prevention Explained

backflow-preventWhat is Backflow?

Backflow occurs when water moves in the opposite direction from its normal flow. When there is a change in pressure and the direction of the flow is reversed, backflow can allow contaminants to enter the potable water supply.

Why Do You Need A Backflow Prevention Device?

The device ensures the quality of your water and prevents any contaminants from entering BSU’s potable water supply. Having cross-connection control and backflow prevention programs in place is critical to safeguarding your drinking water.

Cross-connection is the most common form of contamination.

A cross-connection is a permanent or temporary piping arrangement that can allow your
drinking water to be contaminated if backflow occurs.

Some Examples of Backflow Incidents:

  • Backsiphonage of lawn chemicals through a garden hose into the water system, resulting from negative pressures in the distributing pipes of the potable water supply. Over half of the nation’s cross-connections involve unprotected garden hoses.
  • An irrigation pump, hot water heater or other means that can cause a back pressure higher than the supply can result in backflow into the water system.

BSU works hard to protect your drinking water from contamination. This effort begins at the wells, where the water is collected, and continues through the treatment and distribution processes.

Remember to follow guidelines for landscaping around the meter box and backflow prevention devices to allow BSU employees easy access to this equipment. Together, we are protecting the health and safety of you, your family and your neighbors.
