“Backflow” is reversal of normal course of water through a water route. When back flow occurs, contaminants in non-potable sources get into the water supply through cross-connection and pose great health risk. A cross-connection is any connection between drinking water supply and sources of non-potable water. Controlling cross-connection is very important for ensuring safe and clean drinking water.
Backflow occurs in two ways:
Back-pressure: Back-pressure occurs when the pressure on the customer's side of the connection is greater than City's water supply system, and pushes water back into the system.
Back-siphon age: This occurs when there is significant drop in pressure in main distribution pipes. Removal of large amount of water from the system (for instance, due to water main break or firefighting) causes the drop in pressure, which can pull water back into the system from nearby connection.
Backflow prevention: Because of the risk of water contamination and associated health hazards, cities have placed regulations for backflow preventer installation. Currently, Industrial, Commercial, Institutional (ICI) properties, and multi-residential properties of five or more units, where there is a greater potential for backflow and contamination to the water supply, are required to install backflow prevention devices.
Various kinds of backflow prevention devices are available in the market. Certified Backflow Prevention Specialists determine the type of appropriate device based on the degree of contamination.
