FACT: Temperature can increase during summer months, taking it above the acceptable temp of 20°C, extra checks may be required

Cold water storage tanks (CWST) are what feeds the sinks, hand wash basins, showers, toilets etc within various types of buildings. Cleaning, disinfection and sterilisation through chlorination or use of chlorine must be carried out annually or more frequently, if required.

Keeping cold water storage tanks clean, will prevent sludging, sediment and scale, all of which provide favourable conditions in which Legionella bacteria can grow. Removing scale and biofilm is also important as bacteria can be hidden within a biofilm forming a barrier to disinfectants.
