Best Well Water UV Disinfection Systems

Treating Well Water with Ultraviolet Light

For households on a private well, UV water disinfection can be an effective way to ensure that bacteria, viruses, and other harmful pathogens are eliminated from your well water.

Three top options for well water treatment include:

- - Viqua Arros 15-IHS22
  - Viqua VH410M
  - Viqua VH4100

If you already have another type of water filtration system installed (such as a sediment filter, water softener, etc), you can pair that filtration setup with either the Viqua VH410 or VH410M ultraviolet water sterilizer. The combination makes an outstanding option for treating well water.

If you do not have another type of water filtration system, we recommend the Viqua Arros 15-IHS22 as it has integrated prefilters.

Well Water Treatment FAQs

What type of filtration system is best for well water?

The type of filtration system that is best for well water treatment will depend on the specific contaminants present in the water. Here are some common types of filtration systems used for well water treatment:

Ultraviolet (UV) Disinfection Systems: UV disinfection systems use UV light to kill bacteria and other microorganisms in well water. They are effective at removing bacteria, viruses, and other microorganisms that can cause illness. UV disinfection systems do not remove other contaminants like sediment or heavy metals.
Sediment Filters: Sediment filters are used to remove particles like sand, silt, and clay from well water. They are effective at removing suspended solids and can improve the clarity and taste of the water. Sediment filters are typically used as a pre-filter to improve UV water purifier effectiveness and protect other filtration systems from clogging.
Activated Carbon Filters: Activated carbon filters are used to remove organic contaminants like volatile organic compounds (VOCs), pesticides, and herbicides. They can also remove chlorine and other chemicals that can affect the taste and odor of the water. Activated carbon filters are effective at removing contaminants that can cause health problems or affect the quality of the water.

What is the best way to purify well water?

Well Shocking: Chlorine can kill bacteria in well water. Unfortunately, this method does not provide continual treatment and protection from bacteria.
UV Disinfection: Ultraviolet (UV) disinfection uses UV light to kill bacteria and other microorganisms in water. UV disinfection systems are effective in treating most types of bacteria, viruses and other water-borne microbes. UV systems work around the clock to treat all water coming into a household.

How do I choose a well water treatment system?

Test your well water: The first step in choosing a well water treatment system is to test your well water to determine the contaminants present. You can hire a professional water testing company or use a home testing kit to get an idea of what's in your water.
Identify the contaminants: Once you have the results of your water test, you can identify the contaminants that need to be removed. Common well water contaminants include bacteria, viruses, sediment, iron, manganese, hydrogen sulfide, arsenic, nitrates, and radon.
Determine the treatment method: Once you have identified the contaminants present, you can determine the best treatment method to remove them. Common well water treatment methods include sediment filtration, activated carbon filtration, reverse osmosis, ultraviolet (UV) disinfection, and chemical treatment. UV water sterilizers are generally the quickest and most effective way to treat bacteria and viruses.
Consider the size of the treatment system: You will also need to consider the size of the water filtration equipment you need based on your water usage and flow rate of your well. A household with higher water usage will require a treatment system with greater flow rates.
