The proposed Legionella Control Regulations introduce significant changes to the regulation of cooling tower systems in NSW. In essence, the framework will move to a Risk Management approach.

The proposed changes include compulsory Risk Management Plans (RMP). The requirement is that the RMPs are completed every year for “high risk” systems otherwise on a 5-yearly cycle.


HydroChem combines risk management principles with an in-depth knowledge of all aspects of cooling tower installation and operation.

The Team:

  • Industry experience and qualified
  • Passionate and proactive with a reputation for quickly resolving issues as they arise
