We've put together an infographic, featured below, that provides an overview of common legionella control tasks that should be carried out.

Any water system can provide ideal environmental conditions for legionella bacteria to grow, so it is important that you have checks in place that can prevent and control this risk.

The frequency of inspecting and monitoring can depend on the complexity of your water system and the susceptibility of those on your premises. We provide further guidance on how these tasks should be carried out in our free guide to in-house monitoring.
