Proud to be CanadianPrivate well water is not regulated or treated before it enters your home. That means bacteria, viruses, and parasites like E.coli, Cryptosporidium, and Giardia can be present in your well water - invisible to the naked eye and undetectable by taste or smell.
The Kent UV Disinfection System provides reliable, chemical-free protection against these harmful microorganisms - using ultraviolet light to inactivate bacteria, viruses, and chlorine-resistant parasites before your well water reaches any tap in your home. No chemicals. No taste or odour change. No ongoing treatment costs.
Engineered UV disinfection technology, professionally installed by Kent Water across Southern Ontario.
Designed for homes with private wells across Southern Ontario and the GTA.

The Kent UV Disinfection System uses ultraviolet light to inactivate harmful bacteria, viruses, and chlorine-resistant parasites - including E.coli, Cryptosporidium, and Giardia - in private well water. Unlike chemical disinfection methods, UV treatment adds nothing to your water, changes no taste or odour, and requires no ongoing chemical costs. The system includes integrated pre-filtration for reliable whole house well water protection. Every system includes professional installation and manufacturer warranty coverage.

Unlike city water which is treated and tested by municipalities before reaching your home, private well water receives no treatment or regulation. What's in your well depends entirely on local geology, seasonal conditions, nearby agricultural activity, and groundwater movement - and it can change over time without any visible warning signs.
Bacteria, viruses, and parasites in well water are particularly concerning because:
The Kent UV Disinfection System provides continuous, chemical-free protection against all of these threats.

The Kent UV Disinfection System uses ultraviolet light - the same part of the natural light spectrum that causes sunburn - to destroy the DNA of harmful microorganisms, preventing them from reproducing and causing illness. The process is immediate, chemical-free, and leaves no residual byproducts in your water.

Stage 1: Pre-Filtration
Well water first passes through the integrated pre-filter, which removes sediment and particles that could shield microorganisms from UV exposure. Clean, clear water is essential for effective UV disinfection - the pre-filter ensures the UV light can reach every microorganism in the water.
Stage 2: UV Disinfection Chamber
Water flows through the 304 stainless steel UV chamber, where it is exposed to the UV lamp. The UV light penetrates the cell walls of bacteria, viruses, and parasites - destroying their DNA and preventing them from reproducing. Cryptosporidium and Giardia - which are resistant to chlorine - are inactivated at this stage.
Stage 3: Disinfected Water Flows to Your Home
Water exits the UV chamber and flows to every tap, shower, and appliance in your home - free from harmful bacteria, viruses, and parasites. Nothing has been added to your water. Taste and odour are unchanged.
Continuous Monitoring: The digital controller tracks system performance, helping you stay ahead of maintenance and lamp replacement.

For Southern Ontario well water homeowners, UV disinfection is not a luxury - it is a fundamental layer of protection against biological contamination that no other filtration system provides. Iron filters, water softeners, and carbon filters are all essential for addressing specific water quality problems - but none of them protect against bacteria, viruses, and parasites. A well that tests clean today can become contaminated after heavy rainfall, flooding, or changes in local groundwater - and without UV protection, that contamination reaches every tap in your home without warning.
The Kent UV Disinfection System operates continuously, adds nothing to your water, and requires only an annual lamp replacement to maintain full protection. For any home on a private well - particularly homes with children, elderly residents, or immunocompromised individuals - UV disinfection is one of the most important water treatment investments you can make. It is most effective when paired with pre-filtration to remove sediment that could shield microorganisms from UV exposure - which is why the Kent system includes integrated pre-filtration as standard.
