Legionella are a naturally-occuring waterborne bacteria which exist in freshwater sources, like lakes and streams. When they grow and spread in water systems that create an aerosol – like showers, cooling towers, hot tubs and other plumbing systems – they become a health concern. Legionnaires’ disease – a form of pneumonia – is caused by this bacteria and can be deadly.
The HSE reports that legionella risk is on the rise, as buildings have been closed and water is now sitting stagnant.
There are some groups particularly at risk, including:
- Over 50s
- Those in ill health (for example, chronic lung disease, immune disorders or diabetes)
- Those who smoke, or who have smoked historically
- Those with alcoholism
From legionella awareness training to risk assessments and testing, Opal can help you manage your legionella risk and management. Our experienced team of water treatment engineers and technicians will work with you to ensure that you are operating within law and guidelines around legionella.
Legionella Risk Assessments
A risk assessment should contain thorough documentation of the steps you will take to mitigate the risk of legionella. It should include all parts of the system and plant – all areas that could create a water aerosol or that may be prone to bacterial growth.
Legionella Awareness Training
Legionella awareness training is required for all persons responsible for a water system, particularly where there is a high risk of a water aerosol being produced through showers, taps or other risk systems. Our bespoke training ensures that you manage the risk safely and efficiently.
Our technicians will attend and take a water sample from various points in your system, and can even return a same day result with rapid legionella testing.
