The Public Health Act 2010 and Public Health Regulation 2012 define the roles and responsibilities for managing cooling water systems and other regulated systems.
Cooling water systems must be managed safely in order to prevent the growth and transmission of Legionella bacteria. The legislation requires a risk management approach to managing cooling water systems.
Building occupiers are required to ensure that there are six key safeguards in place for their cooling water systems:
- Risk assessment of Legionella contamination, documented in a Risk Management Plan (RMP) – every five years (or more frequently if required)
- Independent auditing of compliance with the RMP and Regulation – every year
- Providing certificates of RMP completion and audit completion to Council
- Sampling and testing for Legionella and heterotrophic colony count – every month
- Notifying reportable laboratory test results (Legionella count ≥1000 cfu/mL or heterotrophic colony count ≥5,000,000 cfu/mL) to Council
- Displaying unique identification numbers on all cooling towers (Unique identification number is provided by Council).
