What is Backsiphonage?

The positive flow of water can be reversed when there is a sudden reduction in water pressure in the distribution system, such as during firefighting or when a water main breaks.  This can create a suction effect, drawing the non-potable substance into the potable water system.

Where are the devices installed?

The devices are installed on the City’s water supply line as close as possible to the customer’s water meter and/or internally on any equipment that utilizes water that potentially may become contaminated such as boilers, carbonators, cooling towers, x-ray machines, etc.
