EQT has announced that the EQT Infrastructure VI fund has agreed to acquire Seven Seas Water Group, a leader in decentralized water and wastewater solutions, from Morgan Stanley Infrastructure Partners. The deal marks a strategic push into essential infrastructure services aligned with growing global needs for resource efficiency and water resilience.
Headquartered in Tampa and Houston, Seven Seas Water Group operates more than 220 water and wastewater treatment plants across the U.S., Caribbean, and Latin America. The company has implemented its Water-as-a-Service® (WaaS®) model for more than two decades, providing communities with customized solutions for desalination, advanced water purification, and wastewater reuse—critical services in regions facing water scarcity and aging infrastructure.
"EQT has followed Seven Seas and the water sector closely for many years," said Alex Darden, Partner and Head of EQT’s Infrastructure Advisory Team Americas. "Seven Seas provides critical access to potable water in areas where a large portion of the population would otherwise not have access to clean water and wastewater infrastructure. We’re excited to join forces with the Seven Seas team to help drive more efficient water and wastewater management and fulfill their mission to expand access to clean, affordable water."
With increasing climate stress, urban sprawl, and regulatory momentum, demand for decentralized water treatment systems is accelerating. The U.S. Environmental Protection Agency projects a need for $75 billion in decentralized wastewater investment by 2042 to meet national water quality goals. Seven Seas is strategically positioned to address this need through its scalable, sustainable WaaS® platform.
According to Henry Charrabé, CEO of Seven Seas Water Group, "We are excited to build upon the success we've achieved over the years and look forward to further accelerating Seven Seas’ growth trajectory alongside EQT. EQT’s long-term vision and focus on sustainability align closely with our strategy."
EQT plans to enhance Seven Seas’ platform with digital innovation, operational optimization, and geographic expansion, leveraging its global network and infrastructure expertise. The transaction remains subject to regulatory approval and standard closing conditions.
This acquisition signals EQT’s commitment to investing in mission-critical infrastructure that supports sustainable development and water equity—key themes that resonate across global markets and policy agendas.
