Stay Compliant With Cooling System Water Treatments

Legionnaire’s disease is a potentially fatal infection. The disease is caught by the inhalation of water droplets from water systems containing the organism at high levels. Although legionnaires disease is relatively rare, other infections can also occur, such as Pontiac Fever and Lochgoilhead Fever.

There is a greater risk of legionella bacteria developing if water is stored or re-circulated as part of your cooling system, the water temperature in all or some part of the system is between 20–45 °C and there are deposits that can support bacterial growth, such as rust, sludge, scale and organic matter.

The true numbers of legionella infections are not known, but the detected outbreaks attract massive publicity and could cause system operators to be prosecuted for serious offences. 

The HSE publishes an Approved Code of Practice (ACoP L8), which provides guidance on legionella control and legionella testing. Complying with L8 helps you to comply with the law and avoid significant fines or even a custodial sentence.

Cooling towers, evaporative condensers, adiabatic coolers and any other equipment linked to, or with, a stored or re-circulating water source are considered high risk breeding grounds for the legionella bacteria. 

At Aqua, we can provide you with a comprehensive legionella management strategy to help ensure your statutory compliance to ACoP L8 and reduce your risk of a legionella outbreak.
