Why Are Public Water Fountains Being Ignored?
The use of public water fountains and coolers is declining worldwide. Major cities like New York, London, and Tokyo have all seen a drop in their utilization rates. The biggest reason behind this trend is the growing distrust in their hygiene and maintenance. Meanwhile, the consumption of bottled water continues to rise, exacerbating environmental concerns such as plastic waste and the detection of harmful substances like microplastics.
Studies show that a single 350ml bottle of water can contain up to 58 billion microplastic particles, and certain bottled waters may release harmful chemicals like formaldehyde depending on storage conditions. Despite these risks, many people still prefer bottled water over public drinking fountains.
Why is this the case? Looking into the accessibility and maintenance of public water fountains provides some answers. In Seoul, for example, there are approximately 26,491 public drinking fountains, but only 7% of them are accessible for daily public use, excluding schools and public institutions. Similar issues are reported in New York and London, particularly in tourist and suburban areas where access to public fountains is even more limited. Moreover, the lack of clear information about the cleanliness of these water sources discourages public use. This problem extends beyond mere perception—it reflects the broader issue of trust in public water systems.
Hidden Hygiene Issues in Water Fountains and Coolers
Water fountains and coolers provide a convenient way to access clean drinking water in public spaces. However, maintaining them in a hygienic state is a challenge. Both the U.S. Environmental Protection Agency (EPA) and the European Union (EU) emphasize strict hygiene management for public drinking water facilities. Still, in many cases, ongoing maintenance is neglected.
One of the top reasons people avoid public water fountains is hygiene concerns. In a survey, 32.1% of respondents stated that they do not use them because they worry about cleanliness. This means that the concern is not necessarily about the quality of tap water itself but rather the maintenance and upkeep of the fountains and coolers.
Here are the primary hygiene concerns affecting water fountains and coolers:
Difficulties in detecting contamination – Water quality issues often go unnoticed until after contamination has occurred.
Bacterial growth and contamination risks – Stagnant water increases the likelihood of bacterial proliferation.
Trust issues regarding water quality – Even if there are no actual problems, public perception of poor hygiene persists.
These concerns are not limited to public water fountains but also apply to office coolers and filtration systems used in corporate and institutional settings. So, how can these issues be addressed?
Water Quality Monitoring for Water Fountains
To resolve these issues, TheWaveTalk has developed the world’s first high-performance turbidity sensor that can be embedded in appliances. Traditional turbidity sensors are bulky, require regular maintenance, and need periodic calibration. In contrast, our smart sensors feature a compact modular design, allowing easy installation in water fountains and coolers without the need for ongoing maintenance.
What Makes Our Sensor Unique?
Real-time water quality monitoring – Continuously detects suspended particles in water to ensure cleanliness in fountains and coolers.
No maintenance required – Unlike conventional turbidity sensors, ours operates stably for extended periods without needing regular cleaning or recalibration.
Potential for bacterial detection – Our turbidity sensors correlate closely with bacterial concentrations, meaning they can provide alerts if contamination is suspected due to rising turbidity levels.
Award-winning technology – Recognized with the 2025 CES Innovation Award in Digital Health, our ultra-fast bacterial monitoring technology sets a new standard in water safety.
Easy integration – Its ultra-compact modular design makes it easy to incorporate into various water fountains and coolers.
Shaping the Future of Water Fountains and Coolers with Global Standards
Currently, our bacterial monitoring technology is not yet directly integrated into public water fountains and coolers. However, our turbidity sensors can serve as an early warning system for water quality issues. For instance, when turbidity levels exceed a certain threshold, the system can trigger a “Contamination Alert,” warning users of potential bacterial presence.
This approach enhances hygiene standards for drinking water facilities, encouraging greater trust and usability among the public. Research is ongoing to develop real-time bacterial monitoring technology for tap water, which will further refine public water system management worldwide.
A Strategic Choice for the Future of Water Management
With increasing public demand for clean drinking water, real-time monitoring and smart filtration systems are becoming essential rather than optional in the water industry. Our next-generation turbidity and bacterial sensors overcome the limitations of existing technology, providing a safer and more efficient way to manage drinking water.
Leading companies are already adopting these innovations to reduce costs and improve public trust. As you consider your water management strategy, we strongly encourage you to explore our solutions as part of a sustainable water quality initiative.
Enhanced water safety and improved consumer confidence can elevate your brand value and position your company at the forefront of the industry. Don't miss the opportunity to lead the future of water management.
