Tortoise Global Water Fund (TBLU) is a U.S.-domiciled, passively managed exchange-traded fund listed on the NYSE that seeks to track the net total return performance of the Tortoise Global Water Net Total Return Index. The fund provides investors with targeted exposure to global developed-market companies engaged in water infrastructure, including utilities and engineering and construction firms; water equipment and services, such as pipes, pumps, valves, filtration, treatment, and testing technologies; and water management solutions that facilitate distribution, usage, irrigation, and resource optimization. Its portfolio, comprising dozens of all-cap holdings with significant geographic weighting toward North America and Europe followed by Asia-Pacific, targets firms deriving at least 40% of revenues from water-related activities and emphasizes those demonstrating strong environmental, social, and governance practices.
Launched on February 14, 2017, and domiciled in the United States with investment adviser Tortoise Capital Advisors, L.L.C., based in Overland Park, Kansas, the fund underwent a significant rebranding in September 2024 when Tortoise Capital renamed it from Ecofin Global Water ESG Fund (formerly ticker EBLU), coinciding with the sale of its UK-based Ecofin Advisors Limited affiliate to Redwheel. In July 2025, it further simplified its name to Tortoise Global Water Fund and transitioned its benchmark from the Tortoise Global Water ESG Net Total Return Index to the Tortoise Global Water Net Total Return Index, reflecting a strategic evolution in branding and indexing focus. These changes align with Tortoise Capital's broader reorganization of its product suite, including recent mergers among closed-end funds like the integration of TEAF into TYG in November 2025, aimed at enhancing efficiency and scale in essential asset investments. The fund maintains a low expense ratio of 0.40%, daily pricing, and total net assets of approximately $56 million as of late 2024, serving institutional and retail investors seeking resilient exposure to the water sector amid global infrastructure demands.
