Rennes Métropole protects 75 wastewater workers in underground networks with Nomadia Protect — the public authority protecting its employees in the most hazardous environments
Rennes Métropole manages wastewater services for the Rennes metropolitan area — wastewater collection, network maintenance and emergency interventions. Its 75 field employees regularly work alone in underground networks, pumping stations and low-traffic areas — often on shift schedules. As a public authority, Rennes Métropole is subject to strict occupational safety obligations, fully justifying its investment in Nomadia Protect.
The 4 benefits for Rennes Métropole and its employees
- 1🛡️ Enhanced safety — a responsive system for the most extreme environments
Employees know they can rely on Nomadia Protect even deep inside an underground network — automatic detection of falls and immobility, quick access to an SOS button and precise geolocation transmitted immediately. An active safety net that fundamentally changes the sense of vulnerability experienced by employees working alone in difficult conditions.
- 2⚖️ Regulatory compliance — the public authority fulfills its lone-worker safety obligations
Rennes Métropole demonstrates to its employees, unions and oversight authorities that it fully meets its public-employer obligations — with a certified and documented lone-worker protection system. In the event of an inspection or incident, the complete traceability provided by Nomadia Protect constitutes irrefutable evidence of action.
- 3🌿 Peace of mind at work — improved employee engagement and well-being
An employee who knows they are protected works differently — with less stress and anxious vigilance, and greater focus on their mission. The peace of mind provided by Nomadia Protect contributes to the quality of Rennes Métropole's wastewater services and to the attractiveness of roles that are often difficult to fill.
- 4📋 Intervention traceability — actionable data for continuous improvement
In the event of an incident, all data is recorded and available for analysis: trigger time, type of alert, precise location and emergency response time. This traceability is not only useful after the fact — it enables Rennes Métropole to analyze alert patterns, identify the highest-risk areas or times, and adapt its safety procedures accordingly.
Nomadia Protect data is not useful only during an incident — it provides a foundation for continuous analysis. Which areas generate the most alerts? Which times are riskiest? Which employees trigger the most unintentional alerts? These insights enable Rennes Métropole to continuously refine its procedures, equipment and training.
