Definition of Hazard Rating for Cross Connection Control and Backflow Prevention is listed below:

Cross-Connection Hazard Rating
Cross-connections are rated using three degrees of hazard, as follows:

(a) High hazard - Any condition, device or practice that, in connection with the drinking water supply system, has the potential to cause death.

(b) Medium hazard - Any condition, device or practice that, in connection with the drinking water supply system, has the potential to endanger health.

(c) Low hazard - Any condition, device or practice that, in connection with the drinking water supply system, constitutes a nuisance but does not endanger health or cause injury.

in accordance with the Australian Standard AS3500.1.2003.

 

Backflow Prevention Hazard Ratings

Assigning a Backflow Prevention Hazard Rating
A default hazard rating is assigned to a premises based on the business activities undertaken on the premises.  The degree of the hazard rating is guided by recommendations from the Australian Plumbing and Drainage Standards 3500.

Business Activity Change
If the business activity changes within a premises, the hazard rating assigned may be affected.  An accredited backflow licensed plumber should be engaged by the property owner to re-assess the hazard rating.

Disputing a Hazard Rating
There may be instances where the property owners disagree with the default hazard rating assigned to their premises.  In these cases, they should engage an accredited backflow licensed plumber to re-assess the hazard rating and submit the proposal in writing, to Council for approval.

Change of Hazard Rating
All requests to Council to review backflow prevention hazard ratings should be made by an approved plumber on behalf of their customer.  Please submit to Council the relevant application form to reassess backflow prevention hazard ratings, along with any supporting information that may assist the claim.  Council will review and advise of the outcome within 21 days.
