The latest Earth Capital market insights spotlight the rapidly evolving water technology and infrastructure sector, a market now central to climate resilience, public health and long-term economic stability. With 2.4 billion people facing annual water scarcity and demand projected to exceed supply by 40% by 2030, global pressure on water systems is accelerating investment, regulation and innovation.
The report highlights major macro forces, including climate change, population growth, urbanisation, and tightening global regulations, that are reshaping the sector. Anchored around SDG 6 (Clean Water & Sanitation), governments and utilities are increasingly prioritising technologies that enhance efficiency, reuse, digital oversight and climate resilience.
The market is expanding rapidly: valued at $350.7bn in 2025, it is projected to reach $591bn by 2030, with smart water solutions alone expected to hit $57.8bn by 2035. Strong regulatory tailwinds are unlocking new opportunities across treatment, monitoring, leak detection, wastewater recycling, and AI-enabled network optimisation. The sector’s momentum is reinforced by landmark M&A and VC transactions, with leading corporates, impact funds, and water-focused investors actively consolidating, scaling, and backing cutting-edge innovations.
