Legionella and water safety

Legionella is a bacteria that is naturally occurring in water sources such as lakes, reservoirs and ponds. It can enter the water systems in homes through the mains supply and given the right conditions, can potentially pose a threat to your health.


The bacteria is usually not harmful if ingested, but if the bacteria comes into contact with someone with a weakened immune system, they could contract Legionnaires’ disease.


Reducing the risk of Legionella in your home

  • Make sure all cold water outlets run below 20 degrees Celsius and hot water outlets run above 50 degrees Celsius

  • Any taps that are infrequently used should be run through on a weekly basis

  • Descale shower heads and taps at least one every 3 months.
