Every day, your City provides millions of gallons of water to its citizens. Water that exceeds the requirements of the EPA. Before the water is pumped to your home or business, it has gone through careful treatment and numerous tests to ensure quality.
Did you know that your tap water has to meet standards that exceed those for bottled water? Unlike tap water, the quality of finished bottled water is not government monitored.
Congress established the Safe Drinking Water ACT (SDWA) in 1974 to protect human health from contaminants in drinking water and to prevent contamination of existing groundwater supplies. This act and its amendments (1986 & 1996) require many actions to protect drinking water and its sources. One of these actions is the installation and maintenance of an approved backflow prevention assembly at the water service connection whenever a potential hazard is determined to exist in the customer's system. Without proper protection devices, cross connections can occur.
What is a cross connection?
A connection between your drinking water and another source of water that combines the two when a backflow condition occurs. When this occurs, your drinking water can become contaminated.
What is backflow?
Backflow is when the water in your pipes (the pipes after the water meter) goes backward (the opposite direction from normal flow). There are two situations that can cause the water to go backward (backflow):
- Backpressure - the pressure in your pipes is greater than the pressure coming in
- Backsiphonage - a negative pressure in one of the pipes
What is considered a potential hazard?
ANY possibility of pollutants, contaminants, and system or plumbing hazards. For example: fire protection systems, irrigation systems, gasoline refineries and stations, restaurants, hospitals, and manufacturers, just to name a few.
