The world's most advanced technology for cleaning and disinfection....

A hospital carried out a Legionella risk assessment to comply with L8 Legionella prevention. Legionella was detected in the buildings hot water system, highlighting that patients were at risk of contracting Legionnaires disease from the hospitals showers. Additionally, it was noted that the previous bi-annual cleaning of the buildings water system with hazardous chemicals was both ineffective and a health and safety risk.  The buildings management determined that an alternative, safe, on-going treatment method needed to be found.

The buildings management approached Trustwater™TM for a solution to this problem. The key objective was to eliminate contamination within the system and to provide residual prevention from both biofilm and Legionella growth.

Having evaluated the requirement, Trustwater™TM installed a fully automated on-site generating system along with auxiliary dosing and real-time monitoring equipment. Trustwater™TM solutions were dosed into the buildings waterline at the point of entry. The automated system maintains a residual at the required level within the entire buildings water system and delivers real-time monitoring data to the buildings management system.

The hospitals water has proven to be free from Legionella and biofilm. The hospital no longer employs chemical treatment companies to perform super-chlorination twice-yearly. The buildings management have peace of mind in the knowledge that biofilm and associated Legionella are not present in their system.  Additionally the buildings management no longer have to tolerate the risk of chlorine poisoning associated with periodic chlorine shock-dosing.
