A medical treatment centre, built in 2005, had previously experienced persistent legionella counts on previous new builds. The difficulty of maintaining minimum temperatures throughout the hot water system was a significant challenge, in spite of the design brief. Furthermore, the Trust was fully aware of the difficulties and costs associated with keeping TMVs infection-free.
Tarn-Pure equipment was installed on the cold water storage tanks at the build stage so both hot and cold water supplies are treated. All the water in the building is treated with copper and silver ions, ensuring complete disinfection. Subsequent testing has confirmed the efficacy of the Tarn-Pure installation with consistently negative or low counts.
