The Nature Flow® Water Treatment System enables the homeowner to make use of all water collected via rainwater tanks without the worry of waterborne bacteria, viruses and other contaminants.

It is a chemical free water treatment system that uses patented self-cleaning ultra violet technology to effectively disinfect greater than 99% of waterborne bacteria and viruses*. Ultraviolet water treatment is also effective against Cryptosporidium* and Giardia* – two viral organisms commonly found in tank water especially after heavy rainfall. Nature Flow Systems benefit from the use of patented self-cleaning UV technology - chemical free and non-mechanical.

  • Low maintenance - only one service a year.
  • Minimal mechanical parts, do not have blowers operating constantly and the submersible pumps in the system only operate on average 25 minutes per day.
  • Low energy consumption.
  • Quiet operation - no noisy aerators or blowers running constantly in the background.
  • The system can withstand prolonged periods of non-usage (such as holidays) without costly re-activating.
