Legionella Disinfection

Legionella bacteria are found in damp and wet environments. If you have a thermostatic mixing valve installed that limits the temperature of your water, you need a Legionella Disinfection plan for commercial sterilisation of water.

Legionella Disinfection: commercial UV sterilisation of water

If you’ve installed a TMV, it’s to keep the people in the organisation’s care safe. Part of that care is ensuring the yearly inspections are completed and the water being provided is sterilised.

Two main risks are associated with water temperature: bacteria growth and scalding. Too low promotes the growth of disease-causing bacteria, and temperatures delivered too high can increase the risk of scalding.

If you have commercial UV sterilisation of water, you must ensure that every year the UV light is serviced with the UV globe replaced, the sleeve pulled out, cleaned, flushed and put back together.

Legionella Disinfection FAQs

Warm water is a breeding ground for dangerous Legionella bacteria. Disinfection of the water takes place when the water flows past the built-in UV lamp. It generally only takes 20-30 seconds, and the water will be safe.

It is a requirement for healthcare facilities to comply with the NSW Code of Practice for the Control of Legionnaires’ Disease, which has been adopted as a policy for implementation in all healthcare facilities in NSW. A copy of the Code of Practice can be downloaded from the NSW Health website.
