Legionella pneumophila testing kit

Detect legionella pneummophila in your water in only 48 hours

Why is it important to monitor Legionella pneumophila?

For sanitary purposes, water system owners and operators are subject to regulations requiring monitoring of this pathogenic bacterium in their installations.

Legionella risk in the showers for public facilities.

All water systems are concerned.

Public buildings, hospitals, local authorities, spas and industries: all public and private actors operating hot sanitary or air cooling water systems must ensure that legionella concentration remain below the regulatory threshold at all points throughout the network.

Legionella health risk in water

If the threshold is exceeded

According to the rate of legionella found in water, health auhorities may order water service shuting off due to a high sanitary risk. The installation operator must then take the corrective steps and provide evidence of treatments to health authorities before he can resume network operation. How? By conducting an assay through a certified laboratory which requires more than 10 days to provide results.

Hot water networks and legionella risk management

In case of contamination

Every installation owner or operator is both civilly and criminally liable regarding sanitary risk management.
