UV Water Disinfection Systems


If your water comes from a private well or lake and you worry about the microbiological safety of the water, Rainfresh UV Water Disinfection system could be the solution that you have been looking for.

Rainfresh UV system (sometimes called UV sterilizer) disinfects water by using the natural, non-chemical disinfection properties of ultraviolet light (UV for short). UV light inactivates bacteria (e.g. E. coli), coliform, viruses and other microorganisms using a germicidal wavelength of 254 nm & a UV dose of >40 mJ/cm², making the water safe to drink from virtually any potable source.

UV disinfection is used by many municipalities across the world including North America for primary disinfection of water. It has multiple advantages over conventional chemical disinfection methods, such as

  • UV systems are highly effective against a broad range of microorganisms including bacteria, viruses & parasitic cysts such as Cryptosporidium & Giardia
  • UV systems do not alter the water chemistry and thus there is no affect on taste, odour or colour of the water
  • UV systems do not create disinfection byproducts such as Trihalomethanes (THMs) which are suspected carcinogens. (THMs can be created when disinfection chemicals such as chlorine react with certain organics in the water)
  • UV systems are extremely easy to operate




Rainfresh UV system is installed on the main line, after the pressure tank and any other treatment devices (e.g. water softener, iron filter etc), before the water line divides into hot and cold. As water flows through the UV system, the UV light instantly disinfects water, making it safe to drink.

 Rainfresh UV system is ideal for homes, cottages, laboratories, industries, offices etc. and available in 3 sizes – 5 US GPM, 8 US GPM  & 12 US GPM.

  • All models are independently tested for > 40 mJ/cm2 UV dose at end of lamp life (NSF/ANSI 55A dose requirement)  at rated flow
  • They feature an audible alarm and visual LED lamp expiry indicator (with 7-day override feature) to show end of lamp life - 9000 hrs of use (approx 1 year) 
  • Includes electronic ballast, power cord and mounting hardware, UV lamp & quartz dome
  • Installs easily in 60-75 minutes - instructions for do-it-yourself installation included 
  • Tested and certified by CSA international to CSA B483.1 & NSF/ANSI 61


For a UV system to work properly, water must not have any colour or tannin. Also, for waters with high hardness, iron or manganese, additional pre-treatment may be required. If you are unsure about your water quality, you can send a water sample for a free water analysis.
