Backflow incidents pose a serious threat to water quality and public health. Whether you’re managing a commercial facility, a school camp, or a community centre, having a structured approach to backflow prevention is essential. One of the most effective ways to build a resilient system is by categorising your risk management activities into five key types: Preventive, Detective, Reactive, Supportive, and Informative.
In this article by The Risk Edge Group’s Annette Davison and Sarah Loder and the Backflow Prevention Association of Australia’s, Peter McLennan, we explore what each of these means in the context of backflow control—and how they work together to protect your water supply.

1. Preventive: Stopping Backflow Before It Starts
Definition: Activities that stop something from occurring.
Preventive measures are your first line of defence. They aim to eliminate the risk of backflow before it can happen. This includes ensuring that the right devices are installed based on the hazard level of each connection.
✅ Example:
Installing a specific cross-connection control device (e.g. RPZ valve, double check valve) as per the connection’s hazard rating.
These devices are critical in preventing contaminants from entering the potable water supply.
2. Detective: Spotting Trouble Early
Definition: Activities that tell you if something is about to occur or has occurred.
Detective activities help you monitor your system and detect early signs of failure or risk. These controls are essential for timely intervention and are often technology- or inspection-based.
🔍 Example:
Monitoring systems that track pressure changes or water quality at high-risk connections.
(More on these controls in a future article.)
3. Reactive: Responding When Things Go Wrong
Definition: Activities that allow you to respond and correct something.
Even with the best preventive and detective systems, incidents can still occur. Reactive activities ensure you’re prepared to respond quickly and effectively to minimise harm.
🚨 Example:
An incident and emergency management plan that specifically covers backflow incidents, including containment, communication, and corrective actions.
4. Supportive: Enabling Effective Risk Management
Definition: Activities that support appropriate risk management.
Supportive activities provide the infrastructure and tools needed to manage backflow risks effectively. These systems help ensure that tasks are completed, records are maintained, and compliance is achieved.
🧰 Example:
Systems for managing backflow records and documentation, including automated reminders for testing and maintenance.
5. Informative: Building Awareness and Accountability
Definition: Activities that increase risk management awareness and probability of implementation.
Informative activities help embed backflow prevention into the culture of your organisation. They ensure that everyone involved understands their role and the importance of proper backflow control.
📣 Example:
Documentation and programs tailored to the end user, such as:
- Backflow training programs for practitioners
- Backflow policies for plumbers and customers
Conclusion: A Comprehensive Approach to Backflow Safety
By aligning your backflow management strategy with these five activity types, you create a system that is not only compliant but also proactive, resilient, and well-supported. Each category plays a vital role in ensuring that your water system remains safe, reliable, and trusted by those who depend on it. Want to find out more?
