Protecting Water Quality in British Columbia
BC Water blog.jpg

Like our friends at Interior Health, we believe in fresh, clean drinking water for everyone—including here at home in British Columbia.

B.C. is a natural wonderland. With nearly 350 bodies of water and more than 290,000 watersheds, water fuels our bodies and our adventures year round. As a province, we pride ourselves in living harmoniously with the natural resources that surround us, and recognize the importance in protecting water quality for decades and generations to come. We know firsthand how access to potable water positively impacts quality of life.

However, developed nations like Canada and the United States are not impervious to water quality issues. At any given time there are dozens of water quality advisories in effect for rural and remote communities across the country. Add to this a growing list of environmental and societal pressures: things like climate change and population growth are altering aquatic ecosystems, and aging infrastructure places us at increased risk of contamination. To guarantee our water supply stays clean and safe to drink, we must invest in innovative, proven solutions.

As part of the province’s water plan, government officials urged British Columbians to “think about how we can help protect our water and how the government can support these actions.” Our UV-LED water purification products—designed and developed in B.C.—rise to this challenge. We saw an opportunity to leverage UV-LED technology to combat water quality issues and answer the call for a system that is both cost- and energy-effective.

Did you know:

  • Over 40% of B.C. residents are served water through pipe systems that are at least 50 years old. (Source: The Value of Water)

  • Revitalizing B.C.’s aging water and wastewater infrastructure will cost an estimated $3,200 per resident, for a grand total of about $13 billion. (Source: The Value of Water)

  • The average B.C. resident uses 490 litres of water per day, which is among the highest per capita water use rates in the world. (Source: Living Water Smart)

  • An estimated 91% of British Columbians get their water from municipal water systems, and 86% of the water that feeds into these systems comes from rivers and lakes. (Source: The Value of Water)

  • Piping for the province’s municipal water, sewer, and stormwater systems spans 80,000 kilometres—enough to circle the earth twice. (Source: The Value of Water)  

 

Water Quality Resources

UV-LED: A Powerful Low-Power Solution

Across Canada, dozens of First Nations communities are under drinking water advisories. Whether water quality is unknown or confirmed not safe to consume (due to poor filtration or equipment failure, for example), these populations are at risk of exposure, contamination, and illness.

Many First Nations and remote communities also have limited access to power and maintenance resources, and rely on diesel generators to supply electricity; this makes water purification solutions like reverse osmosis or UV lamps problematic, as both have significant power requirements. UV-LED water purification, however, operates on little power, requires minimal maintenance, and is proven to have a long product lifespan.

To confirm UV-LED as a viable, effective solution for off-grid water disinfection, we travelled to Ontario, Canada and carried out microbial tests with an EPA-certified third party on pond water adjacent to Grand River and Laurel Creek. Both bodies of water supply drinking water to rural and urban communities, and are known to be heavily contaminated with Total and Fecal Coliform, a bacteria found in most natural water sources that indicates the possible presence of microbial pathogens.

Using a basic filter, 12V battery, and water pump, we tested untreated water against three flow rates to evaluate our water purification systems’ ability to eliminate coliform bacteria. As shown below, pond water can be passed through an Acuva system at a low to medium flow rate, and potable water can be processed twice as fast and meet NSF purification standards. Further, complete TC inactivation and elimination of other microbial contaminants is feasible at a UVT lower than 95% of most water treatment systems.

Our vision at Acuva is to make safe drinking water accessible to communities around the world, finding new ways to reach new markets. We continue to explore applications and improvements for our proprietary technology, reducing form factor and increasing disinfection capabilities.

UV-LED: Mercury-Free Water Disinfection
UV-LED vs UV Lamp.jpg

Mercury is a naturally occuring and highly toxic element; so toxic, in fact, the World Health Organization named it one of the top ten chemicals of major public health concern. Even limited exposure can threaten the nervous, digestive, and immune systems, impairing function and often causing irreversible damage. Mercury pollution has devastating effects on the environment as well and of the estimated 5,500 - 8,900 tons of mercury emitted into the atmosphere each year, only 10 per cent is traced back to natural sources.

To address this global issue, in 2013 the United Nations Environmental Programme (UNEP) introduced the Minamata Convention on Mercury. This international treaty is designed to control mercury emissions and protect human health and the environment; since its inception, nearly 130 countries have come together and begun making changes to phase out a number of mercury products by the year 2020.

Mercury may be present in a number of consumer products, from batteries and barometers to automotive parts and thermostats. Most relevant to the water purification industry, however, is its prevalence in ultraviolet (UV) lamps. UV light is a proven way to disinfect drinking water, and while increasing numbers of water treatment facilities are adopting this technology, many are unaware of the potential risks and performance limitations associated with relying on conventional UV lamps:

  • High maintenance and operational requirements put users at risk of mercury exposure in the event of a lamp breaking or other accident.

  • Because mercury lamps require a longer warm-up time to achieve stable, high-performance results, UV lamps run continuously—even when there is no water flow.

  • UV lamps have a short lifespan, and must be replaced regularly.


At Acuva, we are proud to be part of the mercury-free movement. Since LEDs don’t require mercury, all of our UV-LED water purification systems are fully compliant with the Minamata Convention, offering a practical, effective, and scalable alternative to UV disinfection without the use of hazardous UV lamps.
