It is not always necessary to take water samples and have them tested for the presence of legionella bacteria. The risk assessment will help to identify if you need to conduct routine monitoring as part of your legionella control regime. The written scheme sets out when and where you need to take samples.
A methodical sampling and testing programme is one way that you can show that adequate control is being achieved. However, reliably detecting the presence of legionella bacteria is technically difficult and requires specialist laboratory facilities.
ICE can help you understand whether water sampling is required and if it is, set up planned sampling and testing regime using water industry trained samplers and approved laboratory facilities.
