The Case for Coordination

Why water needs market infrastructure.

The barrier to financing water resilience is not simply a shortage of capital. It is the absence of shared infrastructure to connect projects, standards, and investors. We are working to help close that gap.

Today's Reality
  • Fragmented projects
  • Multiple funding sources
  • High transaction costs
  • Limited institutional participation
The Opportunity
  • Standardization
  • Portfolio aggregation
  • Blended capital
  • Impact verification
Our Vision

WaterFundable is developing infrastructure intended to help coordinate these components into a more efficient capital ecosystem for water resilience.

Who Is This For

WaterFundable is designed to serve four partners in one ecosystem.

Water utilities bring the projects. Institutional investors bring the scale capital. Impact investors and foundations fund the yield subsidy that makes borrowing affordable. Corporate water stewards bring verified demand for watershed outcomes. No single group can close the water infrastructure gap alone. Collective action makes it possible.

General Information for Utilities
Water Utilities and Project Owners

Learn how drinking water, wastewater, and stormwater utilities generally access private capital through bond aggregation structures, what the process looks like, what types of projects fit, and what changes for your community when the rate comes down from 5 to 7 percent to 3 to 4 percent.

A Framework for Collective Action

Water security requires shared effort across four interconnected groups.

No single sector can close the water infrastructure funding gap on its own. In the model we are developing, water utilities would bring the projects, institutional investors would purchase the blue climate bond, and impact investors and foundations would fund a yield subsidy intended to make borrowing more affordable. Corporate water stewards would contribute to that yield subsidy pool and create verified demand for watershed outcomes in the basins where they operate. The architecture is designed so that when all four act together, the math works.

Water Utilities and Project Owners
You bring the projects
Screened, shovel-ready capital improvement projects in drinking water, wastewater, stormwater, and green and gray infrastructure. Faster, lower-cost financing without surrendering operational control.
Institutional Investors
You bring the scale capital
Pension funds, insurance companies, and ESG-aligned funds access investment-grade, infrastructure-backed, impact-verified private water bond portfolios sized for institutional allocation.
Impact Investors and Foundations
You bring the yield subsidy
Foundations, impact funds, and program-related investment vehicles commit concessional capital into a separately managed yield subsidy pool before the bond is issued. This subsidy reduces the effective interest rate utilities pay throughout the life of the bond, without appearing inside the bond structure itself.
Corporate Water Stewards
You bring the verified outcomes sponsorship capital
Companies with CDP, Alliance for Water Stewardship, and science-based target commitments contribute grant capital to the yield subsidy pool and generate verified demand for watershed outcomes in the basins where they operate. In June 2026, Microsoft announced it replenished more water than it withdrew globally in FY25, an early milestone toward its 2030 water positive commitment, and has invested $500M+ across 75 water and wastewater projects since 2020.
