Cooling Tower Audits – what does the NSW Public Health Regulation require?

May 27, 2023

The NSW Health Regulation sets out six key requirements or “safeguards” as part of the risk management approach:

  1. assessing risk of Legionella contamination and preparing a Risk Management Plan (RMP) – every 5 years (or more frequently if required)
  2. independent auditing of compliance with the RMP and Regulation – every year
  3. providing certificates of RMP completion and audit completion to the local government authority
  4. sampling and testing for Legionella and heterotrophic colony count – every month
  5. notifying reportable laboratory test results (Legionella count ≥1,000 cfu/mL or heterotrophic colony count ≥5,000,000 cfu/mL) to the local government authority
  6. displaying unique identification numbers on all cooling towers.
