8 Things You Didn’t Know About Ultraviolet Water Purification Systems

Glasses of water

If you’re like many other Canadians, then chances are you spend a good amount of time trying to make the healthiest decisions for you and your family. As you may already know, drinking water is essential to a healthy and well-balanced lifestyle. In fact, many studies have shown that adults should be drinking at least eight glasses of water a day. With such a high water intake, it’s important to ensure that the quality of your water is up to par. With help from an ultraviolet (UV) purification system, that can become a reality.

Let’s take a closer look at what UV water purification systems are and how they can help.

What is a UV System?

It’s simple.

An ultraviolet (UV) water purification system removes contaminants from untreated water using a physical and chemical-free process. Electromagnetic radiation is used to decontaminate the water from various chemicals, bacteria, and other contaminants, including:

  • Cryptosporidium
  • Giardia
  • Dysentery
  • E. coli
  • Salmonella
  • Giardia
  • Bacteria
  • Viruses

The process begins with a germicidal or mercury vapour lamp that creates ultraviolet light. A glass component of the lamp creates a transparent surface for the shortwave UV light to pass through. The shortwave radiation ultimately eliminates any bacteria or microorganism that it encounters.

Even though UV disinfection is quite effective, it does not remove dissolved organics, inorganic compounds or particles found in the water. It also tends to compare favourably with other water disinfection systems in regard to cost, labour, and user-friendly operation. UV water treatment is quick, energy-efficient, and approximately 20,000 times more effective than just boiling water.

Things You Probably Didn’t Know

Are you thinking of investing in an ultraviolet water purification system? Here are some things you probably didn’t know!

You Should Know How Much Water You Use

UV water purification systems aren’t a one-size-fits-all solution. You should have a general idea of how much water you use, what flow rate you will require based on the number of bathrooms in your home, and the quality of the water in your house before installation.

They Can Be Used for Well Water

UV systems can be used for well water, including private wells. Unfortunately, since private well water is not regulated by most municipalities, you should contact a local lab that can provide an analysis of your water. This includes testing for E. coli, bacteria, and other contaminants.

Cottages & Seasonal Homes

Do you own a cottage or make use of a seasonal home? An ultraviolet purification system can be a great addition. This easy and low-maintenance system is just what you need to ensure that the lake water drawn to your cottage is safe for consumption.


UV purification systems are generally an environmentally-friendly solution, especially when compared to many of the other home water treatment solutions available. They have no disinfection by-products, don’t waste water, have low electrical needs, and do not require any chemicals.


Other than the initial investment in the purchase of the system, the costs are generally quite low. All you really have to worry about is replacing the lamp and sleeve about once a year.


There are only four disinfection methods for home water that are approved by the U.S. Food & Drug Administration (FDA) - and ultraviolet purification is one of them!

Taste and Odour

UV systems effectively remove/reduce chlorine from the water, ultimately helping improve the taste and odour of the water. The best part? It does this without the use of harmful chemicals.

An Effective Solution

With all of these wonderful benefits, it’s sure a good thing that it’s an effective solution! UV purification systems can destroy up to 99.99% of microorganisms.
