First Abu Dhabi Bank enters water finance with impact investing partnership in MENA

First Abu Dhabi Bank (FAB) has taken a further step into water finance, forging a strategic partnership that links one of the UAE’s biggest lenders with Water.org and its impact investing wing, WaterEquity. The aim? To broaden access to safe water and sanitation across emerging markets.

According to the announcement, FAB has committed funds to the WaterEquity Everspring Fund, this is a vehicle designed to channel capital via local financial institutions already serving low-income communities. The goal is clear, but quite ambitious really: to help households and small businesses secure affordable loans for taps, toilets, filters, storage tanks, sanitation upgrades, and related infrastructure.

What makes this deal truly noteworthy is that it’s sitting right at the intersection of several pressures shaping climate tech and development finance in the Gulf region. Water scarcity is worsening, climate volatility is adding more stress on supply systems, and gaps in sanitation continue to negatively impact health, productivity, and household incomes in poorer markets. In that context, market-based finance is increasingly being seen as a promising approach, especially for reaching communities that are too poor for normal bank lending but too expensive for aid alone.

FAB mentioned that it’s the first commercial bank in the Middle East and North Africa (MENA) region to partner directly with both Water.org and WaterEquity through an investment vehicle of this kind. The bank also noted that any profits or gains from this investment will go towards supporting Water.org’s mission, introducing a sort of philanthropic element within a framework that’s centred on repayable capital.

WaterEquity, created by Water.org, operates on impact investing principles rather than relying on grants. Its model involves funding water and sanitation solutions by investing in enterprises , including microfinance institutions. Their Everspring Fund is open-ended, meaning it’s designed to serve as a continuous source of capital, rather than being a one-off or finite fund. The idea is to recycle funds over time, supporting growing demand for lending.

The logic behind it? Work through local lenders who understand their markets best. These lenders can then provide microloans and small-scale financing to families and service providers who need modest amounts, help with installing a household connection, getting a toilet, a water filter, or a storage tank. It’s not usually about large utility projects, but smaller, more approachable upgrades.

The challenge, of course, remains huge. The UN estimates that around 2.1 billion people still lack access to safely managed drinking water. Billions more don’t have safely managed sanitation either. The gap is especially noticeable at the household level, where the costs of improvements might be beyond what people can afford directly, but too small or informal to attract conventional project finance. That’s the space WaterEquity and its partners are aiming at.

Water.org, co-founded by actor Matt Damon and social entrepreneur Gary White, has long argued that affordable financing can be key in solving this issue. Their model promotes connecting families to credit rather than framing water access as just a charity matter. WaterEquity was set up to bring private capital into this field, helping fund institutions, service providers, and infrastructure operators working with low-income communities across emerging and frontier markets.

For FAB, this deal also fits into their larger sustainability strategy. The bank has been expanding its environmental, social, and governance (ESG) financing activities, including blue finance tools linked to water, oceans, and marine projects. This new partnership adds another layer, not just ecosystems, but the basic services that are crucial for public health and economic stability.

Recently, the UAE has been sharpening its water agenda on the international stage. The UN announced that the 2026 UN Water Conference will be co-hosted by the UAE and Senegal, running from December 2 to 4. The focus? Accelerating progress on Sustainable Development Goal 6, getting everyone access to clean water and sanitation. Interestingly enough, UN materials mention that civil society accreditation is already being managed through the conference platform, laying out the importance of this event diplomatically and politically.

FAO (the Food and Agriculture Organization) also sees the conference as a chance for governments, UN agencies, NGOs, and other stakeholders to coordinate efforts on water security. The broader context, in other words, makes this partnership particularly timely. It’s not just about kicking off a financial deal; it’s part of the UAE’s broader efforts to position itself as a leader in water scarcity solutions, investment, and innovation.

Hana Al Rostamani, FAB’s group CEO, pointed out that water is fundamental to economic resilience, sustainable growth, and long-term stability. In her words, the partnership blends capital with expertise to support scalable, market-driven solutions, aimed at boosting water security and creating lasting value for both communities and economies.

Gary White, CEO of Water.org and co-founder of WaterEquity, commented that this collaboration demonstrates how capital markets can be harnessed to resolve one of the world’s most persistent development challenges. He believes that affordable finance can enable families to secure safe water and sanitation, improving dignity, health, and economic mobility in the process.

What makes this model attractive? Well, its combination of scale and discipline. Because loans are repaid, the capital can be reused, creating a sustainable cycle. Involving local institutions helps make the delivery more tuned to actual demand. Plus, focusing on small loans means the model can reach households and small businesses, those often invisible to large infrastructure projects.

Of course, it’s not without risks. Lending needs to stay affordable, local lenders must have good underwriting and consumer protections, and currency fluctuations can impact returns. Climate shocks, too, threaten repayment ability, and impact claims will need solid measurement if investors and policymakers are to trust the system.

Even so, this FAB-WaterEquity partnership hints at a broader shift in development finance. For lenders in the Gulf, climate-related investments are no longer just about solar or decarbonisation, these days, they’re moving into essential areas like water and sanitation, where funding can have immediate positive impacts on individuals’ health, resilience, and daily life.
