Additional Comments:
Beginning January 1st 2010, all backflow assembly testers shall be required to recertify once every five (5) years in order to maintain “active tester” status. Once re-certified, for each of the next four years you will only need to renew your British Columbia Water and Waste Association (BCWWA) membership (i.e. by sending in your renewal form and payment) and submit a test equipment calibration report in order to maintain active status. Once re-certified, you will no longer be required to notify BCWWA of having tested a minimum number of backflow prevention devices as part of your annual renewal.

To better serve our cross connection control community, BCWWA is now offering written examination re-writes at our offices during the last week of each month. This means that examinees will no longer have to wait for training institutions to have a scheduled exam session that they can tag onto.

Beginning 1st May 2009, all students wishing to sit Cross Connection Control (CCC) exams must register directly with BCWWA at least 2 weeks prior to sitting the exam. We have requested scheduled examination dates from each of the training institutions, who are in the process of updating these in our on-line registration system. Each examination sitting will be shown on our website as ‘an event’ that students who qualify will be able to register for and pay the examination fee online. Once payment is received they will be confirmed for that particular examination sitting.

Occasionally, BCWWA receives requests from testers who either did not take the exam at the time of training or who wish to re-take an exam. If you only wish to sit for part of the exam (either just the written or just the practical), please send an email to containing:
1. Your name and contact information,
2. Where and when you completed the CCC Course and the date you last sat the exam,
3. If you can remember, the name of the individual who proctored the exam
4. Whether you wish to re-sit the written or practical exam
Please do not hesitate to get in touch with Aaron Louie, the CCC Coordinator at 604-433-4389 ext 221 if you have any questions or comments.

Textbook is included and will be given out at first class.
