Cross Connection Control Program

 

What is a cross connection?

A cross connection is an interconnection between the potable drinking

water line and any connection with non-potable water, gases, or

chemicals.

Where do we find cross connections in the home?

Garden hoses connected to an outside water tap are the most common

sources of cross connections in the home. The garden hose creates a

hazard when submerged in a non-potable water such as a swimming

pool or when attached to a chemical sprayer for weed killing. Other

common sources of cross connections in the home include connections

of lawn sprinkler systems, boilers, and appliances to the drinking water

plumbing.

Who protects public drinking water from cross connections?

Your public water supplier is required to survey all industrial,

commercial, and institutional facilities to ensure that all cross

connections are eliminated or protected by an appropriate device. The

water supplier is also responsible for inspecting each device to ensure it

is providing maximum protection.

At your workplace - it is the owner’s responsibility to ensure that

every cross connection is eliminated or protected by a backflow device.

The owner must also ensure the device is in working order and has

been registered with the Town of Groton’s Water Department.

What can I do to make sure my water supply is protected from

cross connections?

• Have all changes to your plumbing system performed by a licensed

plumber.
