Temporary building closure
It is recommended that the planned water management inspections continue even during temporary closure of the building(s) as this is when stagnation in the water system is most likely to occur.
During temporary or prolonged periods of closure, we recommended that three basic control measures are taken during the routine weekly inspection of the building to minimise stagnation and any build-up of bacteria within the water system even if the perceived risk of legionella is considered low in your building(s).
- All taps and showers should be run for two continuous minutes at least once a week
- Hot water should reach a temperature of at least 500C
- Cold water should be below 200C
A record of any water checks should be recorded and kept as part of the water management plan for your building(s) if required.
