What COHIN ENVIRONNEMENT does

COHIN ENVIRONNEMENT, founded in 2003 and headquartered in Versailles, France, is a turnkey wastewater treatment plant designer and builder operating as a subsidiary of the COHINVEST Group (a diversified building trades holding founded in 2010). The company develops and deploys two proprietary technology platforms: UNIBIOCELL®, a patented single-basin biological wastewater treatment process based on Sequencing Batch Reactor (SBR) technology with extended aeration that combines biological treatment, decantation, treated water evacuation, and excess sludge withdrawal in sequential cycles while accepting continuous hydraulic feed; and the WASTE WATER BOX (WWB), a modular, extensible product family available in maritime container, PEFC-certified wood, steel/fiberglass composite, composite slab, and biodisc variants, enabling rapid deployment and footprint efficiency below 0.2 m² per population equivalent.

The company serves two primary customer verticals: municipalities and urban communities requiring compact or emergency wastewater infrastructure, and industrial operators (paper mills, truck/tanker washing facilities, packaging plants, maritime ports) requiring treatment of complex effluents or water recycling. Named reference customers include Nice Côte d'Azur Métropole, Smurfit Kappa, SODECO, Groupe DESERT, and TMG Loudéac in France, as well as Essaouira Commune, ONEE, and Berkane Municipality in Morocco, and the FASEP Ukraine project in Khust. Geographic operations span France, a wholly-owned Moroccan subsidiary (Cohin Environnement Maroc, Casablanca), and project activity across the broader African continent (Tunisia, Senegal, Côte d'Ivoire, Uganda) and Europe (Ukraine).

Revenue is generated through four streams: turnkey wastewater treatment plant construction (one-time project revenue), design/audit/consulting/technical assistance (professional services), WWB unit rental (recurring), and maintenance & operations contracts (managed services). Go-to-market is direct enterprise field sales responding to public tenders and private RFPs, supplemented by an international network of commercial partners and trade show participation at Pollutec, Carrefour de l'Eau, the World Water Forum, and African water sector events. Pricing is quote-based on a project basis; no public pricing or financial disclosures are available. The company employs 1–10 people, is privately held with no disclosed external funding, and is supported operationally by sister companies COHIN CONSTRUCTION and PERFO SCIAGE DIAMANT within the COHINVEST group.

Core offering

COHIN ENVIRONNEMENT designs and builds turnkey wastewater treatment plants for urban and industrial applications, anchored by its patented UNIBIOCELL® biological process (single-basin SBR technology) and the modular Waste Water Box (WWB) product family. The company delivers projects from design and engineering through equipment supply, installation, commissioning, and ongoing maintenance, and integrates circular eco-technology covering water reuse and sludge recovery.

Product overview

COHIN ENVIRONNEMENT operates as a turnkey wastewater treatment solutions provider since 2003, offering both physical infrastructure and services. The core portfolio centers on two proprietary product lines: the UNIBIOCELL® patented biological treatment process (a single-basin SBR-based system for urban and industrial wastewater), and the WASTE WATER BOX (WWB) modular unit family available in steel/fiberglass, wood, maritime container, composite slab, and biodisc variants. These products are complemented by a suite of services spanning design/engineering, auditing/consulting, maintenance/operations, and specialized treatment services for domestic, industrial, and sludge applications. The company also offers rental options for the WWB line, enabling temporary or mobile treatment solutions. All offerings are grounded in circular eco-technology principles focusing on water reuse, sludge recovery, and resource optimization.

Direct peers

• Kingspan Klargester: Kingspan Klargester provides packaged wastewater treatment plants and biological treatment units (e.g., BioDisc, BioFicient) for domestic and commercial applications. Both compete in the small-to-medium packaged WWTP market with similar biological/extended-aeration process technology and rapid deployment.
• Fluence Corporation: Fluence Corporation designs and delivers modular, decentralized water and wastewater treatment systems packaged in containers and skid-mounted units - directly comparable to COHIN's Waste Water Box line and rapid-deployment model. Both target municipal and industrial customers seeking compact, fast-to-install treatment in underserved or remote sites.
• BioMicrobics: BioMicrobics specializes in decentralized, small-flow wastewater treatment systems including the MicroFAST and BioSTREAM products for residential, commercial and remote applications. It competes directly with COHIN's WWB modular line in offering packaged biological treatment units to municipalities and developers.
• WPL Limited: WPL is a UK-based manufacturer of packaged and containerized wastewater treatment plants (e.g., the Atplas and Diamond ranges) using SBR and biological processes. It overlaps directly with COHIN's UNIBIOCELL® offering in serving small communities, campsites, and industrial sites with turnkey modular solutions.
• Organica Water: Organica Water provides biological wastewater treatment solutions including compact and containerized plants for municipal and industrial clients across emerging markets. Like COHIN, it targets decentralized treatment with reduced footprint and serves regions such as Southeast Asia and Africa where centralized infrastructure is limited.

Emerging players

• Orenco Systems: Orenco Systems produces decentralized wastewater treatment products and packaged treatment plants (AdvanTex) primarily serving North America. It shares COHIN's focus on compact, packaged biological treatment for off-grid and decentralized sites but operates in a different geography.
• ATB Water: ATB Water is a French SME engineering and equipment supplier for water and wastewater treatment plants, including packaged and modular units for municipalities and industries. It is closely comparable to COHIN in size, geography (France/Africa), and customer profile, often bidding for similar small-to-medium WWTP tenders.

Broad incumbents

• Veolia Water Technologies: Veolia is a global water major offering municipal and industrial wastewater treatment plants, EPC services, and operations & maintenance. It is a broader incumbent that competes with COHIN on large municipal tenders and O&M contracts but is not focused on the small, decentralized, containerized niche where COHIN specializes.
• SUEZ Water Technologies & Solutions: SUEZ designs, builds and operates wastewater treatment plants of all sizes globally using a broad portfolio of biological and membrane technologies. As a diversified incumbent, it competes with COHIN for municipal and industrial WWTP contracts, especially in France, the Maghreb and Africa.
• Degrémont (Suez subsidiary): Degrémont is the historical French EPC contractor for municipal and industrial WWTPs and has built numerous plants across France and Africa. It overlaps with COHIN in turnkey wastewater plant construction and is a particularly relevant incumbent in the French and African markets where COHIN operates.
