New NSW Legionella Legislation Released

NSW Health has released a new standardized approach to managing water-cooling systems in NSW. The new legislation introduces significant changes to the current regulations on cooling tower systems and will impact every organization in NSW.

As an industry expert, Nalco Water has been involved in all NSW Health discussion meetings to ensure we are fully across the new regulation and the impact this will have on your business.


With increased liability concerns, many facilities are facing the need to develop effective prevention programs for waterborne pathogens, such as Legionella. 

We offer continuous supplemental disinfection systems and monitoring services for potable water and other water systems as part of a managed program to control microbial hazards such as Legionella.

Whether those steps require short-term remediation, such as hyperchlorination or thermal eradication, or long-term control strategies, such as supplemental disinfection, point-of-use water filters or even a cooling tower system protocol, you need an experienced partner in water safety to provide guidance.
