Water cooled ventilation systems can be hazardous because they generate fine water droplets that can be carried in air currents. As they are often located on roofs of large buildings they have the potential to spread water droplets and any Legionnella bacteria over a wide area. The link on the right provides information on how this can lead to an outbreak of Legionnaires’ Disease.
In the event of such an outbreak, it is useful to know where these systems are located to provide a starting point for an investigation and allow the most likely sources to be checked quickly. Therefore, there is a legal requirement for those who have responsibility for air cooling towers and evaporative condensers to provide their local council with certain information.
Links on the right provide:
- the register of air cooling towers and evaporative condensers located in the South Gloucestershire Council area
- a form to notify South Gloucestershire Council of the presence of these systems.
