It is an obligation of employers to monitor and manage their water systems in buildings The control measures required are detailed in the Approved Code of Practice & Guidance L8 ACOP L8 indicates the best method of reducing Risk is Water System Temperature Monitoring Eliminating dead legs and stagnant water is another key element for controlling growth of Legionella Legionella - Legal Obligations

Typically a manual operation requiring access to site by a competent person The frequency and type of testing is indicated in table 3 of the ACOP L8 Open to possible human error Can be expensive and time consuming Legionella - Current Monitoring Methods

FrequencyCheck Cold WaterHot Water Notes Monthly Sentinel taps (see glossary)The water temperature should be below 20°c after running the water for up to 2 minutes The water temperature should be at least 50 °c within a minute of running the water This check makes sure that the supply and return temperatures on each loop are unchanged I.e. the loop is functioning as required. If fitted, input to TMV’s on a sentinel basis The water supply to the TMV temperature should be at least 50°c within a minute of running the water One way of measuring this is to use a surface temperature probe. Water leaving and returning to calorifier Outgoing water should be at least 60°c, return at least 50°c If fitted, the thermometer pocket at the top of the calorifier and on the return leg are useful points for accurate temperature measurement. If installed, these measurements could be carried out and logged by a building management system. Six Monthly Incoming cold water inlet (at least once in winter and once in summer) The water should preferably be below 20°c at all times The most convenient place to measure is usually at the ball valve outlet to the cold water storage tank. Annually Representative number of taps on a rational basis The water should be 20°c after running the water for 2 minutes The water temperature should be at least 50°c within a minute of running the water This check makes sure that the whole system is reaching satisfactory temperatures for Legionella control.
