Disinfection of sanitary hot water systems

Without proper maintenance, sanitary hot water systems can quickly turn into bacteria pools. Some of them, such as Legionella pneumophila, proliferate in silence, until they trigger fatal pulmonary infections for vulnerable people.

To protect the population from the risk of legionellosis, regulations require close monitoring of sanitary systems, as well as shock disinfection treatments if critical thresholds are reached.

Sanitary water systems to be closely monitored

Legionella are micro-organisms naturally present in lake and river water. But in the wild, the concentrations are not high enough to present a danger for human health.

On the other hand, poorly designed or maintained sanitary systems can quickly act as an “incubator” for legionella, which are fond of limescale, stagnant water, and water heated to around 40-50°. These pathogenic bacteria, carried by hot water under pressure, are then inhaled in the form of water vapor or droplets.

Consequently, some public buildings must be closely monitored to avoid any risk for fragile people, whose immune system is weakened. Among these establishments that must implement monitoring measures for facilities at risk of legionella, we find the following:

  • Hospitals, clinics and care facilities.
  • Housing centers for the elderly.
  • Thermal centers.
  • Swimming pools and spas.
  • Saunas, steam rooms, etc.

Our preventive and curative disinfection solutions

Curatec assists managers of housing, entertainment and care facilities in the management of legionella risks.

Preventive maintenance of hot and cold water systems

We carry out annual maintenance operations on sanitary water production and distribution systems. Such an operation involves, in particular, descaling and disinfection as a preventive measure of all areas of use at risk:

  • Showers and baths.
  • Washbasins, sinks, indoor and outdoor taps.
  • Peripheral elements of faucets such as hoses.
  • Water misting systems.
  • Air conditioners and cooling systems.
  • Fountains, etc.

As an option, we also offer regular sampling to detect any abnormal concentration of legionella in the systems. The samples taken are then sent for analysis to a COFRAC accredited laboratory.

Shock disinfection of sanitary water circuits

Have bacteriological controls carried out in your establishment revealed legionella levels above the alert threshold? Our teams then intervene urgently to clean, descale and thoroughly disinfect all the components at risk in the installation:

  • Distribution systems
  • Exchange bodies
  • Pools
  • Boilers
  • Pumps
  • Cooling towers, etc.

After analyzing the characteristics and organization of your sanitary installations, we implement mechanical or chemical disinfection treatments authorized by the regulations, such as chlorine and peracetic acid.
