Protecting Lake Dunlap Drinking Water From Cross Connections

Backflow occurs when contaminated or non potable water reverses flow into the clean water supply. This often happens through cross connections such as irrigation systems, hose bibs, boilers, carbonators, and medical or dental equipment. When pressure in the plumbing system changes suddenly, dirty water can be drawn or pushed back into the drinking supply.

There are two primary causes of backflow — backpressure and backsiphonage. Backpressure happens when downstream pressure exceeds supply pressure, while backsiphonage results from negative pressure that pulls contaminated water backward. Both create serious risks to water safety.

Without proper protection, pollutants, fertilizers, or chemicals can enter the potable system, posing health hazards and liability risks for property owners. That is why New Braunfels Utilities (NBU) and the Texas Commission on Environmental Quality (TCEQ) require annual testing and documentation of all installed backflow prevention devices.
