Backflow and Cross-Connection Control 101


Backflow typically occurs when the flow of a contaminated liquid reverses and mixes with potable (drinking) water. This generally occurs in or between the public water system and something connected within a consumer's plumbing system, which is classified as a cross-connection. The cross-connection sets the wheels in motion for backflow to occur. The two most common types of backflow are backpressure and back siphoning, which are the result of positive or negative pressures, respectively. Back siphoning is commonly caused by main breaks or other conditions that create a drop in the City water distribution system pressure, which allows contaminates to be sucked back into the municipal water supply and the customers internal drinking water supply. Backpressure occurs when a device such as a pump is used to force contaminates into the water distribution system by overcoming the distribution systems water pressure.

The reversal of contaminated liquids can unknowingly infuse pollutants, pesticides, and other harmful agents into the drinking water. Contaminates can come from sources such as a garden hose, a lawn irrigation system, industry, medical facilities, schools or small businesses such as dry cleaners, photo labs, funeral homes, restaurants or the local grocer, to name a few.  The basis for current cross-connection control and backflow prevention is based on the U.S. clean water act, state and local health requirements that have been put in place to comply with the clean drinking water act and increased urgency to secure the water supply since 9/11.


A Serious Health Issue
Some cases of backflow being introduced into the drinking water supply may cause an odor or discoloration and provide you with a red flag, but it is just as common to find contaminates containing chemicals or biological hazards that can not be detected by sight or smell. The effects of backflow can be as common gastroenteritis or could be much more serious, including organ damage or even death.
