A New Era of Sanitation Arrives at France’s Train Stations

France has rolled out AI-enabled public toilets at some of its busiest train stations. These next-generation sanitation systems, which blend artificial intelligence with advanced automation and real-time monitoring, are now operational in cities like Paris, Lyon, and Marseille. The initiative, launched by the French national rail company SNCF in collaboration with sanitation technology firm Cleantech Solutions Europe, is being hailed as a game-changer for urban infrastructure.

This innovation goes beyond mere convenience. It’s part of a wider push by the French government and local transit authorities to upgrade aging public utilities, make urban spaces more inclusive, and reduce the environmental and operational burdens of human-managed toilet facilities.

Intelligent Sanitation: How the System Works

At the heart of this transformation lies a suite of smart technologies powered by artificial intelligence. Each AI-enabled toilet pod is embedded with sensors and machine learning software that continuously monitor cleanliness, usage patterns, occupancy, and maintenance needs. The system uses predictive algorithms to detect when cleaning is required, trigger automated cleaning cycles, and even notify maintenance staff in case of malfunctions or vandalism.

The doors open and close automatically, and inside, UV light sterilization is used between uses to disinfect surfaces. Occupants are guided by voice prompts and touchscreen displays available in multiple languages, ensuring ease of use for both locals and international travelers.

There’s also a built-in facial recognition system for detecting unusual behavior, which is designed not to store personal data but to enhance safety. For instance, if someone collapses inside, the system can alert medical responders. Such integration of AI in sanitation marks a shift from reactive facility management to proactive, responsive public infrastructure.

Why France Is Prioritizing Smart Sanitation

The French Ministry of Transport and the Ministry of Ecological Transition have jointly identified public sanitation as a critical area for technological intervention. In recent years, complaints about unhygienic or unavailable public toilets—particularly in high-traffic areas like train stations—have surged. Studies conducted by France’s National Institute of Public Health revealed that poor sanitation access disproportionately affects women, the elderly, and those with disabilities, leading to health complications and social exclusion.

France also faces growing tourism traffic and a rise in domestic train travel due to the government’s push toward reducing short-haul flights. With an increasing number of passengers relying on train networks, clean and accessible sanitation services have become essential. Introducing AI-enhanced public toilets at transit hubs is thus seen as a way to elevate France’s global image while addressing deeply rooted infrastructural gaps.

A Closer Look at the Pilot Installations

The pilot phase began quietly in early 2025 at Gare du Nord in Paris, one of Europe’s busiest rail stations. Within two months, over 100,000 passengers had interacted with the AI-enabled toilets. According to SNCF, user satisfaction ratings skyrocketed from a baseline of 47% to over 90%, largely due to improvements in cleanliness, safety, and ease of use.

Following the pilot’s success, installations were extended to major stations in Lyon, Marseille, Strasbourg, and Lille. The facilities are free to use for the first 15 minutes, after which a nominal fee is charged. This time-based model encourages efficient usage while maintaining affordability for travelers.

The toilets are also fully accessible, equipped with support rails, low-height buttons, and audible instructions for the visually impaired. Gender-neutral cubicles, family units, and baby-changing facilities have been incorporated into every design, addressing diverse user needs.

Cleantech Solutions Europe

The technology behind the project was developed by Cleantech Solutions Europe, a startup specializing in automated public infrastructure. Headquartered in Toulouse, the company was founded by a team of AI engineers and sanitation experts. Their flagship “SanitiBot” platform, used in the train station toilets, integrates IoT (Internet of Things) devices, AI-powered diagnostics, and modular designs to make sanitation smarter and more scalable.

CEO Mathilde Chevrier, speaking at the project launch in Lyon, emphasized that public toilets are often “the most overlooked yet most essential part of a city’s identity.” According to Chevrier, the collaboration with SNCF showcases how public-private partnerships can elevate everyday experiences through meaningful innovation.

“We didn’t just want to create a clean toilet,” Chevrier said. “We wanted to redefine what a public toilet could be—safe, dignified, efficient, and even self-healing in a way.”

Environmental and Operational Benefits

AI-enabled toilets are not only about convenience and cleanliness—they’re also environmentally sustainable. Traditional public toilets consume high volumes of water and chemicals due to inefficient cleaning schedules. The new AI systems optimize water usage by calculating when flushes and cleaning cycles are necessary. They also track soap, paper, and disinfectant levels to prevent overuse or shortages.

Moreover, the real-time monitoring dashboard gives SNCF precise control over maintenance staffing, enabling leaner operations without compromising hygiene standards. Early reports suggest that maintenance-related downtime has dropped by 68%, while water usage is down by nearly 40% compared to conventional public toilets.

These gains are aligned with France’s broader commitment to reducing the carbon footprint of its public services. Under the national “Green Infrastructure 2030” roadmap, smart sanitation has emerged as a priority investment area.

Public Reception and Early Criticism

Despite the overwhelmingly positive feedback, the AI-toilet initiative has not escaped criticism. Some advocacy groups have raised concerns about surveillance features, especially facial detection systems. Privacy watchdogs have called for more transparency on how data is handled and whether biometric information is stored—even temporarily.

In response, SNCF and Cleantech Solutions have issued public reassurances that the AI systems are compliant with GDPR regulations and that no personal data is retained. They also plan to conduct third-party audits to reinforce public trust.

Another concern involves accessibility for the digitally illiterate or elderly populations. Although voice-guided systems help mitigate confusion, critics argue that any system reliant on touchscreen interfaces should include analog alternatives. In response, tactile instructions and physical emergency buttons are being added in future iterations.

Social and Global Implications

France’s AI-powered toilets could have ripple effects beyond national borders. Already, transport authorities from Germany, Belgium, and the Netherlands are reportedly observing the rollout with interest. With the rise of AI and smart city technologies, sanitation is becoming a new frontier of public infrastructure innovation.

International organizations like the WHO and UN-Habitat have praised the project for contributing to Sustainable Development Goal 6—clean water and sanitation for all. By integrating inclusive design and advanced hygiene technologies, France is setting a global benchmark that developing nations and urban planners may emulate in future megacity projects.

The initiative is also changing the public discourse around sanitation. Once a taboo subject, public toilets are now being talked about in the same breath as AI, climate tech, and public health. This shift could help attract more private investment and civic attention to a sector long plagued by neglect and underfunding.

Scaling Up and Evolving

With pilot results surpassing expectations, the French government is considering scaling the technology to airports, parks, and even tourist hotspots like the Eiffel Tower and Mont-Saint-Michel. There are also plans to integrate AI sanitation pods into emergency shelters, hospitals, and festivals, where crowd management and hygiene are often major challenges.

The next phase may also involve further personalization, such as integrating the toilets with mobile apps for real-time availability tracking, booking slots during rush hours, and even tailoring settings like seat temperature and audio guidance for repeat users.

SNCF and Cleantech Solutions are also exploring machine learning upgrades to better predict peak demand, detect emerging hygiene issues through microbial air analysis, and generate maintenance forecasts that could eliminate downtime entirely.

If successful, these enhancements could make France the first country in Europe to implement a fully AI-managed public sanitation network across all major cities.

Smart Sanitation as Urban Infrastructure 2.0

The introduction of AI-enabled public toilets at French train stations represents far more than a technical upgrade—it’s a reimagining of how cities care for their citizens. At the intersection of cleanliness, dignity, efficiency, and environmental stewardship, this project offers a glimpse into the future of smart urban design.

For France, it’s a proud step toward modernization. For the rest of the world, it’s a wake-up call: if AI can manage public toilets more intelligently than humans, what else could be reinvented next?

As one traveler at Gare de Lyon put it: “I didn’t expect to be impressed by a public toilet. But here I am.”
