Ultraviolet Light
The safety of the water supply in your home is the key to a healthy lifestyle.
Where you live, and your water source determines its level of safety. In the end,
you, your family, and your guests will be the ones who will
consume the water from the tap, wherever that tap may
be and in whatever form it may take. Ultimately only
you can determine whether or not you trust the
source and are willing to take that drink!
UV & Microorganisms...
Microbiological contaminants may be in your water supply for a variety of
reasons. Although microbiological issues such as fecal coliform (E-coli),
Cryptosporidium, Giardia Lamblia (Beaver Fever) and many others, may be
contaminating your water supply, Nelsen Water Treatment Solutions (NWS) UV
is a relatively easy solution to any of these problems.
No Chemicals…
UV is safe, easy to use, environmentally friendly, and provides virtually
immediate disinfection without altering the taste of the water or imparting
any potentially harmful disinfection by-products (DBP’s).
Whole House Protection…
For homes that have more than one tap, and that include a bathroom faucet, the
installation of a point-of-entry (POE) UV system is the best choice. Safety is the
main reason for this logic although you may never drink from that bathroom tap.
Safety is the prime reason to install a whole home UV system.
Economical & Efficient…
As long as proper pre-treatment is maintained, an annual system check-up and lamp replacement is all
that is required. The UV system is designed to be left on; a typical household system will draw about the
same energy as a 40 watt light bulb!

What Makes Cleaning Feel Like a Losing Battle

Are you spending more time scrubbing surfaces that quickly get slimy or spotting that just won't go away? This often happens when bacteria or other microorganisms in your well water settle on fixtures and in pipes. You may notice the persistent film on shower doors, or an unpleasant taste and odor that soap doesn’t wash away. These are signs that microscopic life is present in your water, and no amount of surface cleaning alone will fix the root cause.

How the Control Head Manages Treatment Efficiently

At the heart of this system is a metered control head that counts the actual water you use. It has a digital display showing setup and system status, so you’re always informed about its operation. Thanks to Lightlock Technology and an electronic ballast, the ultraviolet light runs at a consistent level. The control head decides when the UV lamp needs maintenance or replacement based on water volume, helping save energy and avoid unnecessary service.

The Role of UV-C Light in Water Sterilization

This sterilizer uses UV-C light to disinfect your water. Unlike filters that trap particles, UV-C light works by disrupting the DNA of bacteria, viruses, cysts, and other pathogens so they can’t reproduce. This method treats water flowing through the vessel without adding chemicals or changing its taste or smell. The media inside is this UV-C lamp, and it suits well water where microorganisms are the main concern.

The Vessel That Holds the Sterilizing Light

The UV system comes in a protective vessel sized for your needs. We confirm the exact dimensions and configuration when sizing your unit to ensure it fits your plumbing setup. The tank holds the UV lamp safely, allowing water to pass close enough for effective exposure without contact. This design supports reliable operation in both residential and light-commercial settings.

Who Should Choose the 9 GPM Version or One of the Larger Sizes

The 9 GPM model is well suited for larger homes or light-commercial properties where flow demands are moderate. If your water use is lighter or your property smaller, consider our 10 GPM or 15 GPM units for a tighter fit. For even higher flow needs, we offer versions handling up to 21 or 36 GPM. Selecting the right size ensures your water receives proper UV exposure every time without under- or over-treatment.

What Comes with Your WSP UV Water Sterilizer

When you order, the complete UV sterilizing system ships directly from Tampa with free U.S. delivery included. The package includes the vessel equipped with the UV-C lamp and control head ready for your licensed plumber’s installation. You also get manuals to guide setup and maintenance. Since we specialize in water treatment, we provide free expert help to confirm your system’s correct size and answer any questions.

Who this size is right for

This is rated for roughly 15 gallons per minute of service flow, which suits a large or light-commercial property.

Work out what runs together on a bad morning and size for that figure. Equipment starved of flow does not just run slowly, it stops treating properly.
