Rain Water Tanks - Water Quality Issues

Health
As rainwater falls from the sky, it's mostly free of micro organisms and other pollutants. However, during collection and storage, its possible rainwater can become contaminated.

For this reason, NSW Health doesn't advise using rainwater for drinking when there's an alternative mains water supply available. Find out more about rainwater tank health guidelines from NSW Health.

Rainwater collection
It's important to find out if your roofing materials or the paint used in your catchment areas could contaminate your tank water. Speak to your rainwater tank supplier about testing roofing materials.

Good maintenance is the key to good water quality. Installing screens helps to keep physical contaminants out of your tank, as do first flush devices. Remember to regularly clean first flush devices, gutters and guards.

Backflow prevention
It is important for us to protect our mains water supply from any risk of contamination through backflow from tanks into our supply. This is why we are fitting new meters incorporating a backflow prevention device to most residential properties.
