What Enwa Water Technology does

Enwa Water Technology is a Northern European water treatment system integrator and service provider headquartered in Gothenburg, Sweden, with its primary operating headquarters in Sandefjord, Norway (relocated January 2026). The company serves two principal business areas: Industry & Property (land-based industrial, commercial, and real estate customers, with 600+ delivered solutions) and Marine & Offshore (maritime vessels and offshore installations, with 500+ delivered solutions). Enwa designs, builds, and commissions complete water treatment systems across ten technology categories — including the proprietary EnwaMatic® chemical-free closed-loop treatment, advanced oxidation, biological processes, membrane technology (RO/NF/UF), ion exchange, filtration, disinfection, and sterilization — applied to nine end-use applications such as desalination, drinking water, industrial wastewater, PFAS reduction, process water, and pure/ultrapure water for healthcare and laboratories.

The company's product stack is anchored by EnwaMatic®, a registered-trademark side-stream filtration system that protects HVAC loops without chemical dosing, alongside containerized mobile water treatment units and full central water treatment systems for healthcare (PW/WFI per international pharmacopoeia, DIN EN 285, DSO 15883). Notable enterprise customers include SKB (nuclear waste management), Bakkafrost (aquaculture), TUI Cruises/RCCL, Hurtigruten, Oslo Opera House, the New University Hospital in Norway, Comfort Hotel Bergen, Forshaga Water Treatment Plant, and Mowi/DESS Aquaculture Shipping, spanning nuclear, marine, healthcare, hospitality, food & beverage, public utility, and aquaculture segments.

Enwa makes money through three revenue streams: hardware sales of treatment systems and equipment, recurring service-and-support contracts (commissioning, preventive maintenance, spare parts, operational management), and professional services (water analysis, consultation, installation). Pricing is project-specific and quote-based with no public pricing. The company sells exclusively through direct enterprise field sales, with regional service teams across Norway, Sweden, Germany, and the UK. Enwa operates as part of the EnviroWater Group network (collaborating with EnviroChemie for lab expertise and EnviroProcess for pool water) and is owned by Skion Water Group, which provides group-wide governance and shared policy infrastructure.

• Wärtsilä: Finnish marine technology company providing freshwater generators, sewage treatment, and HVAC water solutions for ships and offshore. Directly comparable to Enwa's marine desalination and water treatment offerings, particularly for cruise, offshore, and aquaculture vessels.
• Aquatech International: Specialist in industrial water and desalination including membrane and thermal technologies. Comparable to Enwa's industrial process water, desalination, and recycle/reuse offerings, though with stronger exposure to oil & gas and Middle East markets.
• Alfa Laval: Nordic-headquartered equipment manufacturer with a strong marine and offshore water/separation business. Directly comparable to Enwa's Marine & Offshore segment, including desalination, freshwater generation, and HVAC water treatment for vessels and offshore platforms.
• EnviroChemie: Sister company within the EnviroWater Group providing industrial water and wastewater treatment solutions including lab and chemical expertise. Closely comparable to Enwa's industrial water and wastewater business, and effectively a sibling that occasionally competes or co-bids with Enwa.

Broad incumbents

• Veolia Water Technologies: Global leader in water treatment EPC and services for industrial and municipal clients. Comparable because Veolia supplies the same types of industrial process water, wastewater, and desalination solutions that Enwa delivers, but at vastly greater scale and geographic reach.
• Kurita Water Industries: Large Japanese water treatment company providing chemicals, equipment, and services for industrial water, ultrapure water, and wastewater. Overlaps with Enwa's process water, pure/ultrapure water, and closed-loop system offerings, especially in semiconductors and power.
• Xylem: Global water technology company focused on transport, treatment, and testing of water across utility, industrial, and residential markets. Comparable through its industrial water treatment, desalination, and metering offerings that overlap with Enwa's technology stack, particularly membranes and pumping systems.
• SUEZ Water Technologies & Solutions: Major water and wastewater treatment technology provider serving industrial and municipal customers globally. Overlaps with Enwa across industrial process water, membrane treatment, and service contracts, but operates at a much larger scale across many more geographies.

Emerging players

• Fluence Corporation: Provider of decentralized water and wastewater treatment solutions using containerized and modular designs. Comparable to Enwa's containerized water treatment offering, particularly for industrial and municipal customers needing rapid deployment, but with a different geographic focus.
