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.
As a public employer, Rennes Métropole is subject to the French Labor Code AND the specific obligations of the territorial civil service. Protecting employees working alone is not optional — it is a legal obligation, and failure to prevent an accident may incur the public authority's criminal liability. Nomadia Protect provides the technical and documentary response to this obligation.
