Emerald Technology Ventures has reached the €100 million milestone for its Global Water Fund II following new investments from Temasek and the Grundfos Foundation.
The venture capital firm announced the additional backing after completing a first close of €60 million in late 2025. The new investors join an existing group that includes Veralto Corporation, Ecolab, SKion Water and Oxy Technology Ventures.
According to Emerald Technology Ventures, the diverse investor base reflects growing global demand for technologies that address water scarcity, climate resilience and infrastructure reliability.
Global Water Fund II is targeting a final size of between €150 million and €180 million and will invest in early- to growth-stage companies developing water-related technologies.
Investment focus across the water technology value chain
The fund aims to accelerate innovation across multiple segments of the water sector, including infrastructure resilience, advanced treatment technologies, water reuse systems and digital monitoring tools.
Emerald said the strategy also focuses on technologies that improve prediction, automation and decision-making across water systems, as well as solutions addressing emerging contaminants.
The addition of Temasek and the Grundfos Foundation brings together institutional investors and industrial players with significant involvement in global water infrastructure and technology.
Dr Helge Daebel, partner at Emerald and head of the firm’s water practice, said the collaboration creates a platform connecting long-term capital with industrial expertise and emerging technologies.
The aim is to support innovation across the global water system while accelerating the development and deployment of solutions that improve water resilience.
Growing venture investment in water technologies
Water technology investment has gained momentum in recent years as governments and industry respond to climate change, water scarcity and ageing infrastructure.
Emerald’s first Global Water Fund has previously supported a range of water technology companies and facilitated partnerships between start-ups and major industrial firms.
Examples include collaborations between technology companies and corporate partners across areas such as digital water management, irrigation optimisation and leak detection.
Emerald, founded in 2000, manages and advises assets of more than €1 billion and focuses on venture investments addressing climate and sustainability challenges.
