NSW Health recommends that people use the public water supply for drinking and cooking because it is filtered, disinfected and generally fluoridated. The quality of public water supplies is regularly monitored and in urban areas this remains the most reliable source of good quality drinking water for the community.
However, a properly maintained rainwater tank can provide good quality drinking water. Providing the rainwater is clear, has little taste or smell and is from a well maintained water catchment system it is probably safe and unlikely to cause any illness for most users.
People who choose to use rainwater for drinking and cooking and people who are not connected to Council’s reticulated water supply should be aware of potential risks associated with microbiological and chemical contamination.

Coffs Harbour Laboratory can provide water quality testing services for private water supplies from rainwater tanks.
