Is rainwater safe to drink?

Rainwater is generally safe to drink provided the water is clear and has little or no odour or smell.  There are some precautions that you can take to ensure water from your tank is clean, such as:

  • cover the inlet to your tank with mesh and a strainer to keep out leaves, mosquitoes and other insects
  • prevent air conditioning runoff from entering your tank
  • regularly clean your roof and gutters, and remove tree branches overhanging your roof
  • install first flush devices to trap bird droppings, leaves and dust from washing into your tank
  • check protective mesh, screens and guards regularly and replace them if damaged
  • have your tank inspected every 2-3 years for accumulated sludge
