What Seven Seas Water Group does

Seven Seas Water Group is a multinational water and wastewater infrastructure provider headquartered in Tampa, Florida, operating more than 200 treatment facilities across the United States, Caribbean, and Latin America and delivering approximately 20 billion gallons of treated water annually. The company pioneered the Water-as-a-Service® (WaaS®) model under which it designs, finances, builds, owns, operates, and maintains treatment infrastructure for municipal, industrial, hospitality, and real estate customers, generating long-duration recurring revenue through Build-Own-Operate (BOO) and Build-Own-Operate-Transfer (BOOT) contracts typically spanning 10 to 30 years. Its technology stack centers on reverse osmosis desalination (SWRO and BWRO), conventional activated sludge and membrane bioreactor wastewater treatment, water reuse and recycling, and sensor-based predictive maintenance supported by machine learning and data analytics. Following its May 2025 acquisition by EQT Infrastructure from Morgan Stanley Infrastructure Partners, the company is positioned to accelerate expansion of its integrated WaaS platform across the Americas while pursuing additional municipal asset acquisitions and new long-term public-private partnership contracts.

Revenue model

1. Water-as-a-Service® (WaaS®) Contracts: Long-term build-own-operate (BOO) and build-own-operate-transfer (BOOT) contracts where customers pay only for water or wastewater treatment services supplied at guaranteed quality and price. Contract terms typically span 15-30 years, providing predictable recurring revenue streams. Seven Seas designs, builds, owns, and operates the infrastructure.
2. Lease Plant Program: Short to long-term plant leasing arrangements where customers can deploy modular treatment systems without large upfront capital costs while maintaining responsibility for operations and maintenance internally. Supports phased growth and preserves cash flow.
3. Asset Acquisition and Upgrade Services: Seven Seas acquires existing water and wastewater treatment assets, providing long-term operational stewardship supported by capital investment and infrastructure expertise. Generates revenue through upgraded infrastructure operations.

Scale indicators6 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Aqua Membranes: Developer of printed spacer membrane technology for RO systems. Thematically adjacent as a potential technology supplier or partner into Seven Seas' SWRO/BWRO asset base.
• Fluence Corporation: Provider of decentralized water and wastewater treatment with modular and lease-based offerings. Comparable on lease-plant / modular delivery model and overlapping customer segments; Seven Seas' CGO Erik Arfalk was previously CCO at Fluence.
• H2O Innovation: Specialist in membrane filtration systems and water/wastewater treatment projects for municipalities and industrials. Comparable on treatment technology and customer overlap, but smaller and more equipment-focused than Seven Seas' full WaaS® model.

Direct peers

• Consolidated Water: Caribbean-focused desalination and water services provider using BOOT-style contracts with government utilities. Most directly comparable to Seven Seas in customer base (Caribbean governments), technology (SWRO), and contract structure (long-term build-own-operate-transfer).
• IDE Technologies: Israel-based desalination and water treatment specialist with global BOOT/BOO project experience. Closely comparable on core technology (SWRO/BWRO), EPC-plus-operate delivery model, and focus on municipal water scarcity solutions.

Broad incumbents

• Veolia Water Technologies: Global water and wastewater major with municipal P3 and desalination capabilities. Overlaps with Seven Seas in municipal BOO/BOOT contracts and desalination but operates across a much broader portfolio of water, waste, and energy services.
• Tetra Tech: Global consulting and engineering firm active in water infrastructure design, permitting, and program management. Adjacent rather than direct: overlaps with Seven Seas in serving municipal water projects but does not own/operate plants under long-term WaaS® contracts.
• Doosan Enpure: Engineering and water treatment EPC plus O&M provider with global desalination and wastewater references. Overlaps on municipal treatment project delivery and operations support models.
• Suez Water Technologies & Solutions: Large global water utility and technology player with municipal concessions and desalination expertise. Comparable on long-term municipal water contracts but operates at much greater scale and geographic breadth than Seven Seas.
• Acciona Agua: Spanish infrastructure group with a dedicated water division executing large-scale desalination and treatment concessions globally. Comparable on BOOT project delivery and desalination technology, but competes across larger tenders with stronger balance sheet.
