# Cross Connection Control Program
The Cross Connection Control Program is in place to ensure the safety of our water supply through backflow prevention.
The City of Cambridge Water Use By-law requires that all buildings (except some residential properties) be equipped with backflow prevention devices. These devices need to be maintained and tested regularly by a licensed backflow prevention device tester licensed by the City of Cambridge.
Submit annual test reports or tri-annual system surveys on the City Application Portal.
New - Learn About Backflow and Cross Connections
###### What is backflow and how would this occur?
Backflow means a flowing back or reversal of the normal direction of water flow. The water supply system is normally pressurized to make sure water flows into your building or plumbing system, but there are times that pressure may be reduced.
If the pressure drops enough that the flow of water reverses, unwanted substances could flow backwards and contaminate the public water supply.
###### What is a Cross Connection?
A cross-connection is any connection, whether permanent or not, between the public potable water system and a possible source of contamination.
Some examples of cross-connections are fire sprinkler and irrigation systems, or plumbing connections to equipment that uses water, such as beverage machines, dental chairs and dialysis equipment.
###### What is a backflow prevention device?
Backflow preventers are mechanical devices that prevent water from flowing backwards into a water supply. There are degrees of protection ranging from a vacuum breaker on a garden hose line to reduced pressure zone backflow preventers commonly used in an industrial setting where chemicals are connected to water lines. The type of device required and location it is installed depends on the application and the threat level.
###### What if I choose to not install a backflow device?
The by-law mandates that every building, except for some residential buildings must be equipped with backflow prevention devices. Failure to install and maintain these devices could result in having your water shut off, and/or a fine.
Instructions for Annual Compliance to the Cross Connection Control/Backflow Prevention Program
##### Maintenance
Maintain existing backflow preventers in good working order. Backflow Preventers must be tested annually by a backflow prevention device tester licensed by the City of Cambridge to ensure they are functioning as intended.
##### Testing
Make sure all the backflow preventers are tested, including devices on fire sprinkler and irrigation systems. The devices must be tested prior to the due date listed on the reminder notice that is sent out by the city.
* If your devices fail, have them repaired or replaced within forty-eight hours.
* If you replace a device, include the serial number for the device that was removed in addition to the serial number for the new device on the test report submitted.
* If you remove a device, a test report must be submitted with the serial number of the device and the reason that it was removed.
##### Cross Connection Survey
Every three years a survey (audit) must be conducted to identify any new cross connections.
* If you need to install additional devices, a building permit will be required and an inspection conducted.
Visit our website or contact [email protected] for permit requirements and submissions.
##### Submit Test Reports and Surveys
When all testing is complete, submit test reports and/or surveys on the City Application Portal.

New - Requirements for Lead Free Backflow Prevention Devices
We would like to remind installers of the requirement to install lead free backflow prevention devices when the device is provided in connection with a potable water system.
As per CSA-B64.0 - 4.1.3 any device connected to a plumbing system intended to convey or dispense water used for human consumption, through drinking or cooking, shall not contain a weighted average lead content in excess of 0.25% when evaluated in accordance with NSF/ANSI 372.
These devices are typically labelled as "lead free" or may have a serial number with LF included.
Any device installed that does not meet this requirement will need to be replaced with an acceptable approved device. If you have any questions in regards to this requirement please feel free to contact our office at [email protected]
