Morgan Stanley Investment Management (MSIM), through investment funds managed by Morgan Stanley Infrastructure Partners (MSIP), its private infrastructure investment platform, today announced it has entered into an agreement to sell its ownership stake in Seven Seas Water Group (Seven Seas Water or the Company) to the EQT Infrastructure VI fund (EQT).

Seven Seas Water Group is a developer, owner, and operator of water and wastewater treatment plants across North America, including the United States, the Caribbean, and Latin America, with over 220 plants currently under management. Through its Water-as-a-Service® (WaaS®) model, the Company delivers reliable, safe, and environmentally compliant water and wastewater treatment to a diverse customer base, including governmental, municipal, industrial and hospitality clients. The Company’s desalination and wastewater treatment plants sign long-term, inflation-linked contracts with take-or-pay minimum volume commitments creating stable, predictable cashflows. Operating in some of the most water-challenged geographies, Seven Seas Water ensures availability for potable and clean water, while maintaining its more than 20-year track record of high uptime, strong customer retention and a world-class health, safety, and environmental (HSE) performance.

The Company is the result of a business separation from non-infrastructure activities which was conducted shortly after a public-to-private transaction. Under MSIP’s ownership, Seven Seas Water has experienced substantial growth expanding its footprint in the United States, particularly Texas, scaling to become the North American Water-as-a-Service® leader. The Company recently secured several high-profile long-term contracts, including with the South Texas Water Authority (STWA), as well as successful project delivery for the City of Alice in Texas.

“Seven Seas Water exemplifies the infrastructure characteristics we prioritize – essential services, long-term inflation-protected cashflows, and operational excellence,” said Alberto Donzelli, Managing Director and Co-Head of Europe for Morgan Stanley Infrastructure Partners. “The Company’s Water-as-a-Service® model has proven highly effective across diverse markets, and we are proud to have supported their evolution into a market-leading platform.”

Markus Hottenrott, Chief Investment Officer for Morgan Stanley Infrastructure Partners, added: “Seven Seas Water is another example of MSIP’s differentiated ability to execute corporate carve-outs and business separations, successfully conduct take-private transactions, build institutional-grade platforms and work with management teams to drive operational excellence. We are pleased to have created a resilient infrastructure business that delivers an essential service to communities and industries across North America and beyond.”
