Targeting Zero Legionella

4 Jun 2019

When faced with old buildings with various pipework congurations, inaccessible deadlegs and deadends this was always going to be a dicult problem to solve. This was exacerbated by the nature of high risk patients within the hospital.

The Februus Sentinal Dosing System has proven to be reliable, robust, cost eective chlorine dioxide disinfection system.

The results broken down:

Over 3080 chlorine dioxide samples were taken over a two year period. Less

than 3% fell under the recommended 0.1ppm while zero fell over 0.5ppm.

580 Legionella samples taken – zero positives.

1680 Pseudomonas samples taken - <1% positive on the pre samples (all

under 10cfu) and zero on the post samples.

Delivered a cost saving of 84.9% on water treatment costs.

Following on from the success of this unit’s performance the Group have installed 12 further units across its portfolio of high risk sites. All the high risk sites have shown similar results in reductions of both positive samples and emergency disinfections.
