The quality of your drinking water can change from day-to-day, season to season. Even if your tap water is safe today, contaminants can infiltrate wells and aquifers, and aging infrastructure can lead to an increased risk of contamination. In fact, boil water advisories are becoming more and more common, even in large cities.
Not all water disinfection technologies are created equal. For example, chemicals can be both dangerous to handle and potentially hazardous to the environment – and some waterborne illness-causing microbes are chlorine-resistant. Reverse osmosis wastes on average three gallons of water for every one gallon it purifies, and is no longer recognized
as a barrier to microbiological contamination. Filters can improve taste, but they generally don’t treat microbiological contaminants.
There is an option that addresses all of these issues: ultraviolet (UV) disinfection or UV water treatment.
The Story of UV
How UV Water Treatment Works
Water is disinfected as it runs through a stainless steel chamber containing a UV lamp. As water flows past the lamp, illness-causing microorganisms receive a lethal dose of UV light that attacks their DNA and eliminates their ability to reproduce. Harmful bacteria and viruses are deactivated, and your family is safe.
UV water disinfection is a safe, chemical-free way to treat water. Even chlorine-resistant microorganisms are made harmless through UV exposure. Lack of chemicals means no harmful chemical byproducts are going back into the environment, and the taste of your water is not affected in any way. Learn more about how UV disinfection works.
Benefits of UV Disinfection
- Easy to install and service
- Economical and energy efficient
- Addresses a broader range of pathogens than chlorine – some protozoa like Cryptosporidium and Giardia are resistant
- Recognized by regulators including USEPA
Where can UV be used?
Short answer: everywhere! Ultraviolet (UV) disinfection of drinking water has been growing steadily in popularity, as people search for a chemical-free solution for ensuring their water is safe from microbiological contaminants.
- Homes and cottages: Home systems are point of entry (POE), which means they’re plumbed directly into the water line where it enters your house. This ensures clean, safe water is available at every tap in your home.
- Camps, RVs, and boats: If your water source is a lake, a well or an on-board supply, don’t let poor water quality ruin your recreation time. UV is a chemical-free solution to protect all outdoor enthusiasts.
- Schools, daycares, eldercare and healthcare facilities: The young, the elderly, and those with compromised immune systems are among those most susceptible to infection. In many jurisdictions, especially if the facility is served by a private water supply, water quality is subject to regulation.
- Offices and public buildings: It’s simply good business to ensure the quality and safety of the water provided for employees and visitors, from washrooms and drinking fountains, to water features.
- Restaurants, hotels and resorts: It’s hard to name an industry that relies more heavily on recommendations and word-of-mouth. Guest experience is everything. Water quality enhances food and beverages, and water safety ensures your reputation.
- Rainwater: More and more homeowners and organizations are opting to harvest rainwater as a private water source and disinfection of that water is required for potable uses
VIQUA UV Systems
Our UV systems are also extremely economical to operate. A typical whole home system uses the same power as a 40-Watt light bulb. Depending on the size of your home, the current quality of your water, and your water source, we can provide a system to meet your needs.
