Innovative Finance for Water and Sanitation - What Can Actually Scale?

22 Oct 2026
Development2030 Main Stage

Despite growing recognition that access to clean water and sanitation underpins health, resilience, gender equality, and economic development, the sector continues to face a significant financing gap. Traditional donor-led models alone are proving insufficient to meet rising demand, particularly in fragile, climate-vulnerable, and rapidly urbanising contexts.

At the same time, a wave of innovative financing approaches is emerging across the WASH sector. Yet many questions remain around scalability, risk allocation, affordability, and whether these models can truly scale and reach underserved and crisis-affected populations.

This session will bring together donors, development finance institutions, utilities, investors, NGOs, and private sector actors to examine what innovative finance for water and sanitation actually looks like in practice and which models are genuinely capable of scaling sustainably.

The discussion will explore:

  • Which financing mechanisms are delivering measurable impact?
  • How can investment models work in fragile and low-income settings?
  • Who should absorb the greatest risks in WASH financing?
  • How can humanitarian, climate, and development financing become better aligned?
  • Can private capital support equitable access without undermining affordability?

The session aims to move beyond theory and focus on practical lessons, operational realities, and scaling WASH financing globally.
