In our previous Technical Bulletin, we considered the importance of maintaining compliance under current ACoP L8, HSG 274, HTM 04-01 and HPSC guidance through the monthly temperature
monitoring of hot and cold water systems, and how data can be important when comparing it with Legionella sample results from the systems.
Poor water temperature control and stagnant conditions can lead to bacterial contamination of water systems, resulting in biofilm formation and Legionella proliferation.
Temperature monitoring remains the traditional and most commonly used method for the control of hot and cold water systems. The process involves a monthly site visit by an engineer to physically check the hot and cold water temperatures and record their findings. Although this method satisfies the current guidance, it only provides a snapshot of the system temperature at that time. It certainly does not tell us whether the water system has the capability to achieve the
required temperatures on a consistent basis.
