If you’re a landlord, there are a number of things you should always consider. Maintenance, minor repairs… One thing most people take for granted is the quality and cleanliness of their water. But without UV disinfection for homes and cottages, it’s difficult to guarantee potability, especially when the source is not the drinking water network.


These days, there are many ways to ensure that the water you drink from your tap is clean, germ-free and fit for consumption. You could certainly get a filter for your tap, or filter your drinking water with a special pitcher, but even these household items can’t guarantee that your water will be completely free of harmful germs. The price may be higher, but it is possible to guarantee clean water in your home.


By using a UV water sterilizer, you can effectively purify all the water that enters your home. These devices cover a wide range. They can be a little tricky to install and require some modifications to your home’s existing water system, but they can make all the difference if clean water is your goal.

You’ll need to pre-treat your water so that it’s already clean enough, free from sediment and taint, for the ultraviolet systems in these units to work properly. They also require annual or bi-annual maintenance. However, these are small prices to pay for peace of mind when it comes to your water.

Water purification system for the home

Ultraviolet treatment is the safest method for disinfecting water intended for human consumption. The reactors selected by 1H2O3 are used to :

  • make untreated water from local resources (wells, boreholes, water intakes, etc.) potable.
  • secure the use of mains water, in particular after dechlorination with activated carbon
  • make recycled rainwater safe to use, for sanitary purposes only

1H2O3 UV sterilizers guarantee compliance with bacteriological water quality limits (in accordance with the FR decree of 12/25/2003) and comply with the French Ministry of Health’s Directive on UV treatment. Prior filtration may be necessary, depending on the quality of your source. As each country has its own regulations, you should check and comply with the standards in force in your country.

Advantages of UV disinfection for human consumption

1H2O3 UV-C treatment for water disinfection and potabilization offers numerous advantages. In addition to technology that guarantees exemplary water quality for drinking water, the UV disinfection system is highly reliable and easy to use.

  • Excellent UV disinfection performance thanks to highly optimized ultraviolet emissions and hydraulic flow,
  • Compact water treatment units for easy installation,
  • Use of specific UV-C lamps for water sterilization,
  • Optional UV sensor or monitor with LED alarm and dry contacts for reporting,
  • Extremely long life of UV water treatment lamps.
  • Easy-to-use treatment. Does not alter the physico-chemical characteristics of the water: no change in taste, odour, etc.
  • No disinfection by-products harmful to human health.
  • No risk of under- or overdosing
  • No need to monitor or handle chemicals
  • Can be combined with other treatment processes (filtration, softening, etc.)

Design advice: UV disinfection for human consumption

Go to the UV design page:

  • Select “Water for human consumption / Sterilization”.
  • Select the water source to be potabilized, e.g. “Potabilization of well water”.
  • Enter the flow rate to be treated (e.g. 2 m3/h, which is more than sufficient for a 4-person house).
  • Adjust the cost of electricity in your country (e.g. 0.09€ for France; 0.23€ for Germany).
  • Enter 40 mJ / cm² (basic value is 30 mJ/cm²)
  • Specify the water temperature (normally, between 5 and 40°c is sufficient, unless you’re pumping water from a well in Canada).

In all cases, to guarantee optimum disinfection and decide whether pre-filters are necessary, we recommend that you carry out a source water analysis with these parameters:
