What Groupe Claire does

Groupe Claire is a privately held French industrial group, organized under CLAIRE HOLDING SAS, that designs, manufactures, and distributes equipment and connected solutions for water networks across drinking water, sanitation, irrigation, natural waters, collective housing fluids, and industrial gas. The group's offering combines physical network infrastructure (subscriber connections, fittings, valves, metering, and bespoke metalwork) with connected instrumentation (sensors, data loggers, acoustic leak detection, connected valves, SCADA supervision, and biosensors) through eight specialized subsidiaries — Ijinus, Wayve, Sainte-Lizaigne, FAST, Hydroméca, EIE, ADG, and Hydreka — unified commercially under CLAIRE SOLUTIONS and supplemented by the CLAIRE PRO E-shop e-commerce platform.

The group's technology stack spans electromechanical equipment (e.g., the OmegaFlex hybrid connection collar, PRIZIUS ultrasonic irrigation valve), connected instrumentation (Ijinus Blue LP and LOG09V4 loggers, FAST BiDi LTE acoustic pre-localizers, WAYVE connected valves), and biosensing (Hydreka's NODE LM, a patented self-cleaning biosensor using bacteria as bioindicators). Manufacturing is conducted in-house across multiple French sites and Germany (FAST), with documented custom-fabrication capability through EIE. The group claims 180+ years of combined expertise anchored by Sainte-Lizaigne (founded 1840).

The business model combines enterprise field sales to municipal water utilities, public-sector buyers, and delegated operators across France plus export markets (notably North and West Africa), with direct-to-consumer equipment sales via the CLAIRE PRO E-shop. Revenue streams comprise one-time hardware sales (fittings, valves, sensors), hardware sales of monitoring and supervision solutions (with rental options through Hydreka), and professional services including training, technical support, and consulting. Pricing is quote-based and not publicly disclosed; the group holds €5,299,521 in registered capital and operates with no disclosed external funding rounds.
