Cooling water and warm water systems notification and reportable tests
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 and warm-water systems must be managed safely in order to prevent the growth and transmission of legionella bacteria. Council is required to maintain a register of cooling water and warm water systems installed in the Ku-ring-gai area.
Responsibilities of building occupiers with cooling water systems
Building occupiers are required to ensure the following are undertaken for their cooling water systems:
- Display of unique identification numbers on all cooling towers. The unique identification number is provided by Council.
- Submission of a Risk Management Plan (RMP) to Council. The risk assessment of legionella contamination is to be documented in an RMP and is to be completed every five years or more frequently if required.
- Submission of an audit report to Council. Independent auditing of compliance with the RMP and Public Health Regulation 2012 is to be completed every 12 months.
- Monthly sampling and testing for legionella and heterotrophic colony count.
- Submission of reportable test results to Council. Reportable test results are laboratory tests where the legionella count is 1000 cfu/ml or greater and heterotrophic colony count is 5,000,000 cfu/ml or greater.
