But what does it actually mean, and why is it so important for this rapidly growing Sydney suburb? What Is Backflow? Backflow is the unwanted reverse flow of water from a property back into the main public water supply. This can happen due to a drop in main water pressure (backsiphonage) or an increase in pressure from a private source (backpressure). When backflow occurs, contaminants such as chemicals, fertilisers, bacteria, or even sewage can enter the drinking water system, posing a serious health risk to the entire community.
