Water System upgrade in Fabrication Firm - Case Study

We were contracted to carry out a Risk assessment on a water system at a large Fabrication company in the UK. Water samples were also taken from various parts of the water system and analysed in the lab.

Legionella bacteria were identified from the samples and the results of the risk assessment revealed that the water system was not up to the required Water Regulation Standards. We upgraded the entire water system.

Why was legionella bacteria in the water?

On further investigation, we discovered that the workers had turned the hot water tank temperature down as it had been scalding their hands. The lower temperature in the hot water cylinder was a perfect breeding ground for the legionella bacteria.
