Seven Seas Water Group is a multinational developer, focused on owning and operating decentralized water and wastewater treatment plants and businesses

Our team has extensive experience in the global water sector, pioneering the Water-as-a-Service® approach, which we believe is superior to traditional equipment sales, engineering, procurement, construction (EPC), and outsourced operations and maintenance (O&M) business models, because our goals are fully aligned with the goals of our clients.

Headquartered in Tampa and Houston, with operations across the U.S., Caribbean, and Latin America, Seven Seas delivers water and wastewater treatment solutions to governmental, municipal, industrial, and hospitality customers and owns more than 150 water and wastewater treatment plants. The Seven Seas Water-as-a-Service® model has been successfully deployed for over 20 years, demonstrating our leading capabilities with project execution, financing, risk management, and operations. In addition to building new plants, the company is actively acquiring existing water and wastewater treatment plant operations.

In 2018, Seven Seas acquired Houston-based AUC Group, a leading provider of decentralized water and wastewater treatment plants throughout the U.S., with over 1,500 installations since 1970.

Seven Seas is 100% owned by Morgan Stanley Infrastructure Partners and serves as their portfolio platform for investments in water and wastewater treatment companies.

The History of Seven Seas Water Group

In 1996, Seven Seas Water Group was established in the United States Virgin Islands with a mission of providing water management services to clients in the fresh water-scarce Caribbean.

In 2007, the company built one of the strongest teams of professionals in the water industry, quickly attracting investors. The company raised the capital needed to expand throughout the Caribbean, entered the South American market, and began exploring opportunities in the Middle East. Seven Seas became one of the fastest-growing privately-owned companies in the water industry and has continued to expand year after year.

In 2018, the company acquired, AUC Group, one of the industry’s leading wastewater treatment corporations, to further expand its offering.

In 2020, Seven Seas was acquired by funds managed by Morgan Stanley Infrastructure Partners, a leading global infrastructure investment platform.

Today, the company has corporate offices in Houston and Tampa, as well as a local presence in all of our markets.
