Fast Localization and Treatment of Microbial Outbreaks in Water Systems

Facility Management

Water systems and cooling systems can provide favorable conditions for the growth of Legionella and other bacteria that pose a threat to human health. Reliable water microbiology monitoring is required to protect people, prevent outbreaks and better maintain the infrastructure.

Legionella bacteria are present in small quantities in soil, rivers and lakes. Artificial water systems can, however, create very favorable conditions for the growth of Legionella. Typical locations of Legionella outbreaks are stagnant warm water pipes, showers, hot tubs, swimming pools and spas. Legionella pneumophila is species of Legionella that causes between 80-90% of diagnosed cases of Legionnaire’s disease, which is a severe bacterial pneumonia (1).

What to Do in Case of an Outbreak?

Speed and reliable results matter.

The technical facility manager takes water samples at defined water sampling points throughout the facility.

Samples are provided for rqmicro.COUNT analysis on-site or sent to the lab. On-site analysis on rqmicro.COUNT can provide results as fast as in 2 hours when performed on-site.

If contamination has been detected, typical measures include temporary closing of affected rooms, replacement of affected shower heads, water flushing and water treatment .

Equally, reliable and fast  Legionella  tests support the fast re-opening of facilities after unused periods or hygiene measures.

Outbreak Management
rqmicro.COUNT enables effective outbreak management in buildings through:
  • On-site testing on rqmicro.COUNT with results available immediately online
  • Localization of outbreaks to take targeted and effective measures
  • Assessing facilities after unused period or upon change of ownership
  • Fast reopening after successful measures
