Davey Steriflo UV Disinfection Units

Ensure your family has access to safe, clean, and chemical-free drinking water with the premium Davey Steriflo UV Disinfection Unit. Specifically engineered to meet the unique demands of New Zealand homes relying on tank water supplies, this trade-quality UV sterilisation system provides a highly effective barrier against harmful pathogens without altering the natural taste or smell of your water.

In New Zealand, rainwater harvesting is incredibly common, but rooflines are constantly exposed to contamination from bird, possum, and other animal droppings. These environmental contaminants introduce dangerous micro-organisms--including viruses, bacteria, and parasitic cysts like Giardia and Cryptosporidium--into your rainwater tank, leaving your water unsafe for drinking and posing serious health risks. The Davey Steriflo system targets these threats head-on, delivering absolute peace of mind for rural properties, lifestyle blocks, and modern residential home upgrades.

How the Davey Steriflo UV Technology Works

The Davey Steriflo system disinfects water by passing it through a chamber where it is exposed to powerful ultraviolet (UV) light generated at a precise wavelength of 254 nanometers. This targeted UV dose damages the DNA of water-borne pathogens, rendering them completely inactive and unable to reproduce. Because this is a natural, physical process, there are zero residual chemicals introduced to your supply, and it is impossible to overdose the system. For optimal performance, these units are best installed inline directly after your sediment pre-filtration system and just before the water reaches your taps.
