Clean, safe
drinking water. It is something we take for granted, but every home may
have potential hazards which threaten to contaminate our drinking water.
Ensuring our water is safe is everyone's responsibility.
THE FACTS ABOUT BACKFLOW AND BACKSIPHONAGE
A cross-connection is the link connecting a source of
pollution with a drinkable water supply.
Two factors are essential for backflow to happen.
First, there must be a link between the two systems. Second,
the force must be greater toward the drinkable supply.
Backsiphonage’ results in fluid flow in an
undesirable or reverse direction. It is caused by atmospheric pressure
exerted on a pollutant liquid forcing it toward a potable water supply
system that is under a vacuum.
Normally, water flows directly from the water mains
to your property, but in certain situations, such as a main break, water
can flow back into the distribution system. Sometimes a main break is not
necessary for backflow to occur.

A SIMPLE EXAMPLE OF THIS IS:
You are watering your lawn with a weed killer
attached to the end of your hose.
When you're finished, you set the hose on the ground
and go inside.
Down the street a city worker shuts off the water to
your house, creating a vacuum in the water main.
The water in your hose gets sucked back into the
water main because of this vacuum, bringing the weed killer
chemical with it.
Later, when the water pressure is restored, you and
your neighbors end up drinking the weed killer after it comes
out of your kitchen faucet!
