Tim O'Halloran always thought rainwater from his tank was clean, that was until he put his water supply to the test during a monitoring project.

Key points:
  • A project in south-west NSW found bacteria in 60 per cent of 17 rainwater tanks tested
  • Guidelines say birds, small animals, and roof debris are the main sources of contamination
  • There are fears climate change will effect the quality of tank water as organisms thrive in warmer water
"You put your rainwater into a little cup, leave it there for an hour or two, then you watch the water turn a horrible, horrible colour and you know it's full of some sort of germs," he said.
"We also sell a range of glassware for technical uses, for laboratories, and masks just seemed to be a good fit. And certainly, with COVID hitting it made even more sense."

The project, conducted at Balranald in the western Riverina, saw 17 water screening tests carried out on rainwater tanks. Sixty per cent of those returned a positive recording for types of bacteria that could indicate the presence of viral organisms that can make people sick.
