Reducing the Risk of Legionella Bacteria With a Tank Reline

Posted on April 20, 2012

There are reportedly over two hundred cases of Legionnaires’ disease annually in the UK causing serious health concerns, which is particularly dangerous for vulnerable and older people as Legionnaire’s disease is a strain of pneumonia. Pinpointing the cause of Legionnaires’ disease is not always possible, however in most cases it is often traced back to non-compliant or neglected cooling towers or potable water tanks, which is one of the reasons why COVAC believe that reducing the risk of Legionella bacteria is essential and easily achieved with a tank reline.

COVAC offer a unique and proven Solvent Free Urethane System which provides long-term protection against corrosion and erosion which in turn reduces the chance of the Legionella bacteria forming and spreading through your water system. Due to the detrimental effect that Legionnaires’ disease can have on an individual’s health, all potable water tanks and cooling towers need to comply with rigorous guidelines.


The Approved Code of Practice and Guidance L8 (ACOP L8) states that there are certain steps that you can take to prevent and control the potential threat of Legionnaires’ disease; these include;

-    Avoid the use of materials which harbour bacteria and other micro-organisms
-    Maintain the cleanliness of the system and the water in it.
-    Control all conditions to avoid the Legionella bacteria spreading and growing
-    Clean your system to reduce the build-up of sediments that could harbour bacterial growth.

Tank lining provides the perfect solution to help you comply with these guidelines, as its unique, ceramic tile – like surface deters the growth of bacteria and micro-organisms, and because it is easy to maintain and clean, the likelihood of Legionella bacteria causing problems is greatly reduced.
