Back flow prevention is an important part of our sewage and draining systems. It ensures that our drinking water stays free from harmful bacteria. This video explains some of the basics of back flow prevention.
If there is no back flow prevention, water from numerous sources can find its way into the drinking water supply. The potable water would be contaminated by water used in chemical facilities, cooling systems, stagnant fire suppression systems, and mainline breaks from the sewer.
Back flow prevention companies will work with the government and utility companies to stage back flow prevention systems in key locations. There are likely thousands of these systems around your city, alone. Many of these are in low-risk settings, but it’s better to be safe than sorry.
Backpressure and back-siphonage are the two main types of back flow that need to be guarded against. Backpressure is when the water supply to a facility is too pressurized and seeks relief by flowing backward into the drinking supply.
Back siphoning occurs when the proper measures aren’t taken to fill up contaminated sources, and pressure being released elsewhere causes the water to be siphoned into the drinking supply. For more information, check out the video above.
