New Zealand has new dam safety regulations. We can help you understand them and get prepared.
The New Zealand Dam Safety Regulations will come into effect on May 13th, 2024, and will affect dam owners with classifiable dams. Dam owners will first need to determine if they have a classifiable dam. The regulations describe the threshold for a classifiable dam as:
- 4 metres or higher with a volume of 20,000m³ or more OR
- 1 metre or higher with a volume of 40,000m³ or more
1. Classifiable dam threshold, from the Dam Safety Guidance document, MBIE - Building Services Branch.
The Potential Impact Classification (PIC)* of the classifiable dam will determine different actions for the dam owner. The process for identifying responsibilities of dam owners is shown in the diagram below.
2. Summary of the dam owner's actions, from the Dam Safety Guidance document, MBIE, Building Services Branch.
The new regulations have assigned timeframes for the submission of the PIC assessment, Dam Safety Assurance Programme (DSAP)** for medium and high PIC dams and the annual Dam Compliance Certificate. A summary of the timeframes is shown below:
