One
of the requirements State Health Regulations impose on all water
purveyors, is that they have a program for identifying and
eliminating cross connections to the potable water system. We
want to assure that all our customers receive safe drinking
water and that the very last user on our water line has water
that is just as safe as the first user and that nothing has
entered the system in between. Help protect your drinking water
from contamination. Install an approved backflow
prevention assembly (shown at right) on all under-ground lawn irrigation systems.
What is a Cross-Connection?
A cross connection is defined as an actual or potential
connection between a public water supply and a source of
possible contamination or pollution. All homes have potential
cross connections. The result of cross connection contamination
is that chemicals, poisons and bacteria may find their way into
your drinking water.
What is Backflow?
Backflow is the undesirable reversal of flow in a potable water
distribution system, as a result of a cross connection. If a
cross-connection exists within the customer’s plumbing system,
it is possible for water from within that system to backflow, or
re-enter the public water system.
What causes Backflow?
There are two conditions that can cause backflow, and one must
be present for a back-flow situation to occur. Both conditions
may exist in the same incidence.
Backpressure: In this condition the
water pressure within the customer’s plumbing sys-tem
exceeds the pressure of the water utility distribution
system. Backpressure may be caused by differences in
elevation, a booster pump or a steam boiler.
Backsiphonage: This condition occurs when the water
pressure in the distribution system falls below the pressure
in the customer’s plumbing system. This localized loss of
pres-sure may be caused by the fire department fighting a
fire, a fire hydrant being hit by a car, or water flowing
from a broken main water line.
TYPES OF POTENTIAL
CROSS CONNECTIONS:
Underground Lawn
Irrigation Systems
Recent technology has provided us with better tools to prevent
backflow. Contaminated lawn surface water can be siphoned back
into your lawn irrigation system unless a proper backflow device
is attached to your system. This device is called a Reduced
Pressure Zone Assembly (RPZ), which requires annual testing. If
you presently have a lawn irrigation system installed without a
RPZ, it needs to be replumbed with a testable RPZ device.
Swimming Pools or Hot
Tubs
Some built in pools and hot tubs are connected with permanent
submerged water fill piping. This could draw disinfectant
chemicals back into your household plumbing system and requires
the installation of a RPZ device.
Lawn and Garden
Chemical Sprayers Attached Hoses
Anytime a garden hose is submerged in or connected to a
container consisting of a potentially harmful substance, such
as, lawn and garden chemicals, and there’s a sudden drop in
water pressure, contamination may occur unless a hose bib vacuum
breaker is used. This is a simple, inexpensive device installed
on the faucet to which the hose is attached.
Other potential cross connections
Almost every bathtub and sink is equipped with the best known
backflow prevention device—an air gap, which is the space
between the highest water level in the fixture and the outlet of
the water from the faucet. However, care should be taken to
avoid leaving attached hoses submerged in contaminated water.
Other possible cross connection locations include: boilers, fire
protection, in-home water treatment systems, solar or Geo
Thermal heating, car washes, decorative ponds, soaking tubs in
laundry areas, and frost-proof yard hydrants, as shown at right.

Protect
your drinking water by taking the following precautions
Don’t:
Submerge hoses in buckets, tubs, sinks, ponds, etc. Use
spray attachments without a backflow prevention device.
Do:
Keep the ends of hoses clear of
all possible contaminants. If not already equipped with an
integral (built-in) vacuum breaker, buy and install hose bib
type vacuum breakers on all threaded faucets around your
home.
How You Can Help
1. Be aware of the possible
cross connection hazards in and around your home or business.
2. If you have a backflow prevention assembly an
annual test must be performed by a State Certified Assembly
Testing Technician and the results must be sent to the Water
Utility. Once you have registered your backflow assembly with
the Water Utility, you will receive an annual Inspection Notice.
We can provide you with a list of qualified testers.
.
What if I Don't Have My RPZ Tested?
The failure of the water customer to install, have
tested and maintain the backflow prevention assembly shall
constitute grounds for discontinuing water service until such
requirements have been adequately satisfied.
