About Cross Connection Control

BCWWA & Cross Connection Control


BC Water & Waste Association (BCWWA) is the recognized authority for the voluntary

certification of backflow assembly testers in British Columbia and Yukon Territory. Currently

our cross connection control (CCC) membership consists of over 1,800 certified testers,

administrators and associate members. Active CCC testers are certified to test

backflow prevention assemblies. They have the knowledge and skills to ensure that our drinking

water systems are clean and safe for our use and consumption. 

What is a Cross Connection?


According to the Canadian Standards Association, a cross connection is defined as any

actual or potential connection between a potable water system and any source of pollution or

contamination. Cross connections are present in every water system, and depending on the size

of the system, hundreds or thousands of potential cross connections can exist. 

What is Backflow?


Backflow is a flow of solid, liquid or gas from any source opposite to the normal direction of flow,                             back into the potable water supply or system.

There are two types of backflow: 1) backsiphonage and 2) backpressure.

Backsiphonage is caused by negative pressure in the supply piping system.
Some common causes of backsiphonage are as follows:
  • High velocity in pipelines
  • Line repair or a break that is lower than a service point
  • Lowered main pressure due to high water withdrawal rate, such as fire fighting or water                            main flushing
  • Reduced supply pressure on the suction side of a booster pump

Backpressure is caused whenever a potable system is connected to a non-potable supply                           operating under a higher pressure by means of a pump, boiler, etc. There is a high risk that the                               non-potable water may be forced into the potable system whenever these interconnections                                       are not properly protected.

Do you own a backflow prevention unit as the owner or in inventory?
