Kali'eau

What Kali'eau does

Kali'eau (legal entity KALI'EAU SAS) is a French engineering consultancy founded in 1996 and headquartered in Lezennes (France), operating as a subsidiary of Groupe KALI alongside sister entities Kalies and Kaliair. The firm delivers technical consulting services across the full water management lifecycle: pollution diagnostics and RSDE regulatory surveillance, water audits and drought action plans, treatability studies, sanitation network diagnostics, hydraulic and stormwater management studies, design and compliance studies for water management systems, and project management assistance (A.MO.) for purification and sanitation/VRD works. Its technology stack is built around specialized CAO software for sanitation plans, hydraulic modeling software with network/hydraulic/earthwork modules, topographic data integration, and GIS/SIG systems — used as interoperability layers rather than as proprietary IP.

The company sells exclusively through direct professional services engagements, with no disclosed pricing model and no digital/self-serve channel. Its customer base is broad and industrial-heavy, spanning agro-food, chemistry/petrochemistry, metallurgy, automotive, logistics, breweries, services (including major utilities and infrastructure operators), and construction. Services are delivered through at least four regional agencies (Nord in Lille, Ouest in Bihorel, Est, Sud-Est), and the firm is actively recruiting across agencies to support expansion. General management is led by Alain Facq (Directeur Général). Group revenue, segment-level financials, and headcount beyond the 12-employee figure cited in firmographics are not disclosed.

The business model is classic project-based professional services: revenue is generated from engineering studies, on-site measurements/diagnostics, feasibility and technical-economic studies, and construction supervision mandates. Customer logos include Veolia, Suez, Dalkia, SNCF, Auchan, Cora, Bouygues, 3M, Air Liquide, PSA, and Prysmian, indicating the firm serves both large utilities/industrials and regional developers/small municipalities. No public disclosures exist on pricing, contract structure, margins, or revenue concentration.
