UV Water Purification
Ultraviolet treatment used as a final stage on supplies where it is appropriate.
In short
A UV water purification system passes water past an ultraviolet lamp as a final treatment stage, most commonly on private well supplies and always after filtration.
The Problem
The problem it addresses
Private wells are not disinfected by a utility, and some homeowners want a final treatment stage in place.
- Untreated private well supply
- Seasonal changes in well water
- A desire for a final stage after filtration
How UV purification works
Water flows through a chamber containing a UV lamp inside a protective quartz sleeve. Clear water is required for UV to work as intended, so filtration always comes first.
- 1Water is filtered upstream so it reaches the chamber clear
- 2Water flows past the UV lamp
- 3Treated water continues to the home
- 4The lamp is replaced on an annual service interval in most systems
Potential benefits
- ✓A final treatment stage with no added chemicals
- ✓No taste or odor added to the water

Results depend on your water conditions and the system selected.
