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.

Urbanization, Water Challenges, and the Rise of Smart Water Cities The United Nations (UN) predicts that by 2050, more than 7 0% of the global population will reside in urban areas. Rapid urbanization intensifies water-related challenges, such as leakage, water quality degradation, and flooding, which are further exacerbated by climate change. These issues place significant strain on urban management systems, driving the need for innovative solutions. Enter the concept of the Smart Water City (SWC) —a forward-thinking approach that leverages advanced Information and Communication Technologies (ICT) like big data and AI to monitor and manage urban water systems in real time. SWC shifts from reactive responses to proactive strategies by continuously tracking pipelines and treatment facilities, detecting anomalies, and preventing issues before they escalate. This paradigm not only enhances water quality and operational efficiency but also offers a comprehensive solution to pressing urban water challenges. Trends in Smart Water Cities Major cities in Europe, such as Barcelona in Spain and Copenhagen in Denmark, have implemented pilot SWC projects. These initiatives use real-time sensors to mitigate river overflow during heavy rainfall and reduce urban water leakage.

Why is Real-Time Turbidity Monitoring Essential for Water Purifiers? Most water purifiers widely used in homes and offices lack real-time turbidity monitoring capabilities. While some purifiers are equipped with TDS sensors, these cannot detect bacteria, microplastics, E. coli, or mold.  As a result, many consumers still feel uncertain about the safety of their water, even when using purifiers. Just as the saying goes, "If you can’t measure it, you can’t improve it,"  the water purification industry must prioritize solving this issue. Global Warning: The Need for Reliable Water Quality Data The importance of this monitoring extends beyond household water quality management. Recently, major European companies like Siemens, Ecolab, Suez, Veolia, and Xylem issued a joint statement to EU policymakers, warning that the lack of reliable water quality data  and standardized measurement systems could undermine water resource resilience. From households to the national level, the need for precise, real-time water quality monitoring systems is becoming increasingly urgent. The Wave Talk’s Revolutionary Solution: The World’s First Semiconductor-Based Digital Turbidity Sensor A water purifier functions as a small water treatment plant within the home. In actual water treatment plants, turbidity monitoring is essential; if turbidity exceeds safe levels, water supply is immediately halted. However, due to the high cost and large size of traditional equipment, integrating such turbidity sensors into household water purifiers has been challenging. To address this, The Wave Talk developed the world’s first semiconductor-based digital turbidity sensor . This innovative sensor allows consumers to monitor water quality in real time, detecting impurities with 1,000 times the precision and 100 times the cost efficiency of conventional sensors.  Its compact size enables easy integration into water purifiers.

AI-based turbidity data analysis is set to become the new standard in pipeline network management. The Limitations of Current Pipe Network Management Systems Current pipeline management systems predominantly rely on reactive methods to detect and address issues such as blockages, corrosion, and leaks. Traditional plumbing management approaches lack predictive capabilities, forcing operators to respond only after problems occur. This reactive approach often results in: Degraded water quality Operational inefficiencies Unplanned maintenance Increased costs due to emergencies The absence of real-time predictive data is particularly problematic when it comes to turbidity—a crucial water quality indicator that measures the presence of particles and potential contaminants. Without timely detection of turbidity changes, minor issues can escalate into significant challenges, undermining water quality compliance and operational efficiency. Addressing these shortcomings requires a shift toward real-time, predictive management systems that allow operators to proactively safeguard infrastructure and maintain water quality.
