Seoul Bolsters Tap Water Safety with Expanded Testing and Modernization Efforts
Seoul is significantly increasing efforts to ensure the safety and reliability of its tap water, known as Arisu, through expanded water quality testing and a comprehensive modernization plan for its aging water infrastructure. Starting March 10th, residents will have access to free water quality tests during evening and holiday hours, alongside the introduction of a novel non-face-to-face testing option utilizing a local delivery app. These initiatives come as the Seoul Metropolitan Government aims to address public concerns and maintain a high standard of water quality, exceeding both World Health Organization (WHO) and domestic standards.
The move to broaden testing accessibility reflects a proactive approach to building public trust in Arisu, despite already high marks for quality. Last year, 75% of Seoul residents reported drinking Arisu water, a 5.4 percentage point increase from the previous year. However, officials recognize that lingering concerns about the condition of indoor plumbing systems necessitate more convenient and comprehensive testing options. The expanded testing schedule, available from 9 a.m. To 9 p.m. On weekdays and 9 a.m. To 6 p.m. On weekends and public holidays, can be accessed by calling the Dasan Call Center at 120, contacting local waterworks offices, or applying through the Seoul Arisu Headquarters website.

Convenient New Testing Options for Residents
In May, Seoul will pioneer a non-face-to-face water quality testing service in South Korea, leveraging the ‘Dakgyoyo’ delivery app. Residents can request a test through the app, leave a sealed container of tap water at their doorstep, and a water quality inspector will collect it for analysis. Results will be promptly delivered via text message. This innovative approach aims to remove barriers to testing and provide a convenient option for busy residents. The city is investing heavily in ensuring the accuracy and reliability of these tests, with Arisu’s water quality assessments encompassing 362 items – more than double the 166 items recommended by the World Health Organization and more than five times the 60 items mandated by domestic drinking water quality standards.
Addressing Distrust and Aging Infrastructure
The expanded testing program is, in part, a response to lingering public distrust, despite significant investments in upgrading Seoul’s water infrastructure. From 1980 to 2020, the city allocated 3.5 trillion won to replace aging, corrosion-prone galvanized steel pipes with newer materials. This ongoing replacement program continues, prioritizing pipes based on their age, and condition. However, officials acknowledge that the primary source of concern now lies within the plumbing systems inside individual homes and buildings. Joo Yong-tae, head of Seoul Arisu headquarters, emphasized that while the city manages the water supply up to the water meter, the responsibility for maintaining the pipes within homes rests with the property owners. He noted that the city’s 160 water quality inspectors are often met with skepticism when testing tap water directly from household faucets.
The on-site testing process provides rapid results, analyzing five key indicators – residual chlorine, turbidity, hydrogen ion concentration (pH), iron, and copper – within five minutes. If abnormalities are detected, the city offers support for pipe inspection, cleaning, and replacement, covering 80% of the replacement costs. Of the 6.69 million tests conducted to date, an overwhelming 99.9% have met drinking water quality standards, demonstrating the effectiveness of Seoul’s water management system.
Enhanced Safety Measures at Construction Sites
Beyond water quality testing, Seoul is as well implementing stricter safety protocols at water supply construction sites. A new ‘Safety Red Card System’ will be enforced, issuing immediate expulsion from the site for workers who violate safety regulations, such as failing to wear protective gear or properly measure gas concentrations in confined spaces. This system represents a shift away from direct public official supervision towards a model of responsible oversight by professional engineers specializing in civil engineering and machinery. To further enhance safety, particularly during excavation perform, the city is deploying ‘work area display devices’ that utilize laser technology to clearly delineate the boundaries of work zones.
Financial Challenges and Future Modernization
Despite the ongoing investments in infrastructure and safety, Seoul faces financial challenges in maintaining its water supply system. The city’s six water purification plants, with the oldest – the Gwangam Water Purification Plant – dating back to 1979, require modernization. Joo Yong-tae revealed that Seoul currently receives no financial support from the national government and that the cost of tap water production is steadily increasing. A fiscal task force is being established to identify potential cost savings, and the city is also exploring the possibility of adjusting water rates to ensure the long-term sustainability of the system. This careful balancing act will be crucial to maintaining the high standards of water quality that Seoul residents expect.
Key Takeaways
