Water Quality Concerns When Reopening Your Business

Due to the COVID-19 pandemic, many business closed their facilities. As regions are now reopening, business owners should be thinking about something they may not have had to give a lot of thought to before: the water quality in their buildings.

If your business has experienced low, or no water flow conditions in your building due to a shutdown, you should be exercising caution in re-opening regarding your water.

According to the U.S. EPA, the COVID-19 virus has not been detected in drinking water supplies at this time and treatment plants have continued to operate and meet the same water standards as always.

This includes the use of residual disinfectant levels in order to inhibit microbial growth in transit. However, even under normal circumstances, the residual disinfectant typically dissipates in a matter of days or weeks.

We're here to help. Ask us what kind of UV system is best for your needs.

Water Quality in Your Building May be Stagnant & Degraded

Since many businesses have closed their facilities for weeks or even months at a time, the quality of water in service lines to commercial buildings and within those buildings may have degraded and become stagnant.

This significantly increases the risk from opportunistic pathogens like Legionella, some Mycobacteria and Pseudomonas aeruginosa. Growth of non-pathogenic organisms could also impact the taste or smell of a water supply.

This is of particular concern where water use produces aerosols, such as:

  • Showers in gyms, fitness facilities and recreational buildings
  • Showers in hotels, motels and B&Bs
  • Taps in hair salons, barber shops and restaurants
  • Even simple toilet flushing

4 Top Water Tips for Business Owners

  1. Understand what actions were taken to bring the building back into service, e.g., flushing, chlorination, etc.
  2. Engage a plumber and/or water treatment professional to service/clean the water treatment equipment within your control.
  3. Communicate with employees and customers about actions taken.
  4. Consider installing a point-of-entry ultraviolet (UV) treatment to minimize risk now and mitigate stagnant water problems in the future.

    After the flushing and disinfecting of the plumbing, your business can now create its own “water ecosystem”.

Further Things to Keep in Mind for Your Reopening

It takes a concerted effort at every level to prepare businesses from a safe water perspective. Utilities, public health authorities, engineers, building owners, plumbers, water treatment professionals and business owners may all need to be involved.

Key Advantages of UV Disinfection

As mentioned above, installing UV water disinfection system will provide a disinfection barrier to minimize risk now and mitigate future stagnant water problems.

  • UV is a chemical-free, environmentally-friendly process, that adds nothing to the water and will not change taste or odor of the water.
  • Requires no transportation, storage or handling of toxic or corrosive chemicals.
  • Highly effective at inactivating a broad range of microorganisms – including chlorine-resistant pathogens like Cryptosporidium and Giardia.

Any subsequent reopenings resulting from COVID-19 or even a boil water advisory will be made simpler and more convenient with your UV system already installed.

Tips for Building Owners

  • Contact your government environmental public health departments for advice about building water safety
  • Work with qualified professionals to bring all building services, including water and sewer, back online
  • Communicate information provided by the health department to your building occupants

Tips for Water Treatment Professionals

  • Try to engage building owners before water services are brought back online
  • Protect water treatment equipment from further contamination during service line and plumbing flushes
  • Perform proper flushing, cleaning, sanitizing and servicing of water treatment systems

RES’EAU WaterNET – Community Circle Approach to First Nations Water Challenges

Trojan Technologies  is dedicated to improving the health of our global environment. We achieve this, in part, by paying close attention to our social, environmental and ethical responsibilities at the community level, as strong communities are the building blocks to a better future.

In Canada alone, over six million people rely on small and rural water systems for drinking water. Globally, this number stretches to 2.5 billion people.

In addition to being remotely located, small water treatment systems are often under resourced, making it difficult to install systems, especially if they require highly trained operators. The result is an increased risk of illness from drinking inadequately treated water and a high number of Boil Water Advisories.

To help tackle this situation,  in 2008 Trojan Technologies began a partnership with RES’EAU WaterNET, a collaborative research program that is part of Canada’s Natural Sciences and Engineering Research Council (NSERC).

RES’EAU is Canada’s first and only collaborative research initiative devoted to meeting clean water demands in small, rural communities.

RES’EAU aims to protect the health of small, rural, and First Nations communities by producing game-changing water treatment solutions, based on the development and deployment of appropriate technologies and community stakeholder involvement.

The Community Circle Approach

In 2013, RES’EAU began a five-year, $7 million program to refine and expand upon its community-centric, impact-focused research programs – otherwise, known as Community Circles. There are currently six community circles located across British Columbia, each focused on addressing the specific needs of the community.

Adapted from First Nations’ traditional approaches, Community Circles are real-life environments where communities, government agencies, researchers and other relevant partners co-create solutions to water challenges.

Dr. Bill Cairns, PhD, Chief Scientist Emeritus, Trojan Technologies, and Chair of the Board for RES’EAU, states:

“In First Nations communities, historically everyone must buy into a solution before it is implemented. This is especially important when dealing with water treatment technologies as water has cultural and historic relevance to First Nations Communities, and new technologies may require new thinking and acceptance.”

At RES’EAU, this inclusiveness manifests directly in the research process by putting stakeholders from the communities at the heart of the innovation cycle, incorporating research insights at the early stages of development.

It is through RES’EAU’s engaging community circle approach that the community, researchers, and others involved are able to determine what solutions are best suited for each community, measuring success not only by technological advancement, but also by a community and social achievement.

The RES’EAU Pilot Trailer

In addition to Dr. Cairn’s participation with the board, Trojan has been involved in a variety of projects and research initiatives with RES’EAU, including helping to launch their first mobile pilot trailer (through the provision of equipment from  VIQUA, a Trojan Technologies business based in Guelph, Ontario).

The mobile unit is used as a convenient way to make different technologies, including UV, available to individual communities and their water treatment system operators. This ultimately helps everyone involved become aware of various technologies’ operational details, and demonstrates the technologies’ performance on the water qualities encountered in different communities.

Utilizing UV technology, as well as filtration and ion exchange, the mobile unit is able directly to evaluate various technological process options that could resolve a community’s water problems and protect community health.

Along with the mobile unit, VIQUA is also involved in a pilot study examining the effectiveness of Point of Entry (POE) water treatment in First Nation communities.  POE treatment systems may be an option for small and remote communities where central treatment is not affordable.   VIQUA not only aids in supplying the UV system for this pilot, but also plays a large role in the research component of the work.


UV technology has been an integral part of the research process at RES’EAU since day one. In addition to UV’s ability to inactivate pathogenic organisms and meet water disinfection standards, UV technology is often more culturally acceptable and/or more practical to operate than chemical disinfection technologies such as chlorination. The added benefit is that no disinfection by-products are generated with the use of UV, whereas significant by-products can result with the use of chlorine. In addition, in many remote communities, shipping in chemicals such as chlorine can be problematic.

By first understanding the needs of the community, solutions that meet both the technological and social definition of success have been derived. This model of problem-solving has led to international recognition in research communities, and has the potential to be adopted globally in addressing the problems of small and remote communities

The work of RES’EAU WaterNET is another important reminder of how success in the water industry will come only from multidisciplinary engagement. The Community Circle Approach demonstrates the importance of prioritizing communication with all stakeholders, and it is this holistic approach to research that leads to meaningful and sustainable results.
