Looking after your water supply

It’s important to look after your water supply to prevent dangerous bacteria such as Legionella from growing and affecting your or your family’s health. Here’s some useful information on what to look out for.

Legionella is a bacteria commonly found in water. The bacteria are inactive below 20°C and don’t survive above 60°C.

Legionella can grow in any home and can cause Legionnaires’ disease.

This is a potentially fatal type of pneumonia, contracted by inhaling airborne water droplets containing Legionella bacteria.

Anyone can develop Legionnaires’ disease, but the elderly, smokers, alcoholics and those with cancer, diabetes or chronic respiratory or kidney disease are at more risk.

What can I do to keep the water safe in my home?

Legionella prefers to grow in stagnant or ‘standing’ water that has been sitting without moving for a significant amount of time. For that reason, it’s important to:

  • flush out infrequently used water outlets (including showerheads and taps) weekly
  • if you’re away from your home for one week or longer, you should flush out the outlets for a minimum of two minutes when you return
  • clean and de-scale shower heads and hoses at least every three months
