Water as a Case Study on the Unpriced Risks of the AI Age

2026-09-15 · By Alix Lebec Founder & CEO, LEBEC

As AI infrastructure expands, its dependence on water is exposing a major investment blind spot. Alix Lebec argues that water scarcity and other interconnected systemic risks remain dangerously underpriced, and explores how blended finance, innovative financial architecture and diversified private-market portfolios can mobilise capital towards resilient water, energy and infrastructure solutions.

A decade ago, investors across the board believed water was an un-investable sector. At the same time, millions of underserved families across emerging markets (particularly women) were demonstrating their bankability, repaying microloans for sustainable water and sanitation solutions at an astounding rate of 97-99 percent. Water.org and its microfinance partners led this model. What was missing was the financial plumbing connecting these two worlds: the broader investor community and millions of underserved families without safe water.

WaterEquity, a global asset manager I co-built alongside Gary White, Matt Damon, and a small team created that financial plumbing. With a portfolio of blended capital funds and a strong thesis anchored around local market demand, and narrative change, we demonstrated the viability of investing in water and how this could impact millions of lives. Today, as the artificial intelligence (AI) boom is projected to consume record levels of freshwater, scaling innovative financial architecture that can move more capital towards solutions is more critical than ever.

As an example, one of our initial funds used philanthropy as a first-loss cushion to help de-risk this opportunity for investors who had never invested in the sector, helping attract $50 million in investments for water and sanitation solutions across developing and emerging markets for the first time. This created an on-ramp for future funds, attracting larger investors, including foundation endowments and corporate balance sheet investments from companies like Reckitt, Microsoft, and Ecolab.

Today, there’s an opportunity to turbocharge these efforts across multiple, interconnected systemic risks ranging from traditional agriculture, forestry, and land use; transportation; infrastructure, including energy and real estate; and health—alongside water scarcity. Innovative financial architecture that can move significantly more capital towards solutions is essential at the enterprise, fund, and portfolio level. Traditional investment portfolios can no longer assume climate stability or endless freshwater availability or follow an investment approach that assumes business as usual. They need to pivot, ensure these risks are accurately priced, and lean toward diversified private market fund portfolios that scale solutions. The AI race presents the ultimate case study for why this needs to happen now.

Today, capital is accumulating and moving at unprecedented speeds; a massive $124 trillion wealth transfer is underway, alongside a new wave of tech IPOs that will create new millionaires, billionaires, and philanthropists. We can’t afford to let this moment bypass the very foundations our survival and global economy depend on. Water sits at the center of a much larger set of interconnected risks and shows the urgency of pricing them accurately and building the financial plumbing needed to scale real, viable solutions using every capital tool in the toolbox.

Water and AI

Despite its absolute necessity for human life and its foundational role in the global economy, water remains dangerously undervalued. By 2030, artificial intelligence is set to consume as much water as 1.3 billion people, arriving at a time when global freshwater demand is on track to exceed supply by 40%.

Meanwhile, today, 2.2 billion people still do not have safe drinking water. As scarcity, climate volatility, and infrastructure constraints intensify, water availability and quality will increasingly influence the cost of food, energy, health, and global supply chains.

We are already witnessing this friction worldwide, in real time. Extreme droughts have lowered water levels from the Panama Canal to the American West and the Rhine and Danube rivers, deeply impacting shipping, trade routes, and logistics. At the same time, outdated infrastructure and severe water shortages are disrupting daily life and basic human needs across Tunisia, Puerto Rico, and Mexico City.

This creates a glaring disconnect. Capital is flowing rapidly toward the AI build out, overly focused on compute (the processing power behind AI) and its immediate infrastructure such as semiconductors, servers, data centers, and power. However, compute is inseparable from water. Investors have almost no exposure to the private market funds scaling the water and clean energy infrastructure our economy, and these very technologies, will need to thrive.

Changing this dynamic is not a money or ideas challenge. It is a design flaw in how we allocate capital.

The Financial Gap

While water has received billions in global subsidies, a significant share of that public support has focused on affordability, service provision, and keeping tariffs below full cost recovery—particularly for households and agriculture. However, unlike other infrastructure industries such as technology, power, and transportation, water has largely missed out on forward-looking, highly risk-tolerant research and development (R&D) capital that can absorb early risks and create an on-ramp for commercial viability. Those forward-looking public and R&D investments gave us the electric car and the smartphone. We need to create a similar bridge for water that encourages both innovation and private investment, while keeping water safely managed and affordable.

Consequently, promising solutions stall, from low-carbon water infrastructure to improved wastewater management systems and water meters, affordable and resilient water connections, and solar-powered water pumping technologies for smallholder farmers. Philanthropy alone cannot scale them, and commercial investment capital often views them as too risky.

However, innovative financial architecture at the enterprise and fund level has demonstrated enormous potential. These models use philanthropy strategically to de-risk innovations at different stages of growth, and crowd-in private and public capital at scale in undervalued sectors like water to scale and sustain solutions.

For instance, at the enterprise level, companies like SunCulture have successfully layered grant, debt, equity, and carbon finance to prove the economic viability of solar-powered water pumping technology for smallholder farmers across Sub-Saharan Africa. This strategic blend of capital increased crop yields for farmers by up to 300% and reduced water consumption by 80%.

At the fund level, managers like Eurazeo and WaterEquity, have demonstrated what is possible when you use innovative financial models strategically. From wastewater management to scaling geothermal energy solutions, Eurazeo has paved the way for innovations across key markets and industries.

Today, we see this visionary leadership expanding into new markets to meet the demands of the technology boom. For example, fund managers like Just Climate are actively backing low-carbon, water-efficient data center infrastructure in Brazil, proving that institutional capital can directly align with the sustainable infrastructure solutions our economies require.

Scaling Through Diversified Portfolios

So how do we scale these efforts with urgency?

The bridge to institutional capital is at the portfolio level. Today, the market has matured, and there are now thousands of specialized private market funds like the ones mentioned above. Many have received backing from at least one institutional investor and demonstrated their potential to scale resilience and decarbonization solutions. These are innovations that address key, interconnected systemic risks affecting all aspects of our global economy.

However, most are still missing from traditional wealth management platforms because they are deemed too niche and too often assessed as a one-off opportunity. We need frontline solutions and institutional financial expertise coming together to build truly diversified portfolios of these funds, aggregating them in a way that addresses and mitigates each of these interconnected risks and targets strong, risk-adjusted returns for investors.

Asset owners want more exposure to these solutions but feel hesitant to invest in solely one fund, one asset class, or one solution, where the risk is amplified. They need access to institutional-grade, multi-asset class, multi-geography, and multi-sector portfolios that address the entire risk map, including climate and scale an ecosystem of solutions. Bridging this gap requires both a deep understanding of how these solutions operate in different markets and the institutional rigor to strategically allocate capital across a well-diversified portfolio.

A recent study by the World Resources Institute amplifies this. Following 320 investments across water, health, agriculture, and infrastructure from 2014-2024, the results show a potential to add $1.4 trillion in economic benefits to our global economy by investing in solutions in these interconnected sectors.

What Now?

Our world is not short of capital. We are simply short on vision, conviction, and the discipline required to build the financial architecture that will let capital already in the system flow to real solutions, valuing and pricing key resources such as water accurately.

In many ways, the AI infrastructure boom is already a water story; capital allocation and public narratives have simply not caught up.

Investors and AI companies have an opportunity to be proactive. By moving capital into diversified portfolios of private market funds that build water and clean energy infrastructure, we can sustain technological progress while preserving our finite water resources. No more business as usual. We have to think and work creatively, use all the financial tools at our disposal, and update our definition of progress to include improving health, economic mobility, and shared prosperity across all communities and economies. It’s possible.
