What NANTAISE DES EAUX does
Nantaise des Eaux (legal entity: Société Nouvelle Nantaise des Eaux) is a France-based PME specializing in the design, construction, and commissioning of water treatment infrastructure for municipalities and, through sister company AQUADEP, industrial clients. The company operates a 30-employee team headquartered in La Chapelle-sur-Erdre and is a wholly-owned subsidiary of the family-owned STURNO group, which reports €210M in revenue and 1,200 employees across water, waste, and civil works in northwestern France; since November 2021, Nantaise des Eaux and AQUADEP have been grouped under the SANDE commercial brand.
The core product portfolio covers four solution lines: (1) municipal wastewater treatment plants (eaux résiduaires) including pretreatment, activated sludge, decanting, sludge handling, odor treatment, and tertiary treatment; (2) drinking water production plants (eau potable) covering deferrization, demanganization, denitrification, filtration, and pesticide removal; (3) JUMBO-SYMAC modular compact stations in glass-reinforced polyester (GRP), sized 50–1,000 EH using extended aeration activated sludge, marketed to small communities, hotels, holiday villages, and airports; and (4) REUT treated wastewater reuse installations available as mobile or permanent configurations. These core offerings are supported by add-on service modules: engineering studies with in-house hydraulic modeling and CAD capability, technical assistance contracts, maintenance and repair, and turnkey rental of installations for emergencies or capacity testing.
Nantaise des Eaux generates revenue primarily through one-time, project-based contracts for custom-built water infrastructure, supplemented by professional services (engineering studies, technical assistance, maintenance) and equipment rental. Go-to-market is sales-led and direct, targeting public maîtres d'ouvrage (collectivités, communautés de communes, syndicats des eaux) and, via AQUADEP, regulated industrial sectors including food processing, chemicals, petroleum and gas, pharmaceuticals, cosmetics, paper, and textiles. Pricing is quote-based and not publicly disclosed. Distribution is exclusively direct with no intermediaries, and commercial activity includes the company website (ndei.fr), LinkedIn presence, and participation in the CGLE water management trade show.
