Private capital for public water infrastructure.

What Cumulus does for your community's water projects
Cumulus is the monitoring infrastructure behind Blu Diamond Water Certificates. We capture continuous, instrument-verified data from your project, creating the auditable record of water savings that corporate buyers and investors need to fund your project upfront. Verified measurement is what turns a needed project into a financed one.
Water infrastructure needs far exceed available public budgets.
Municipal water systems across the United States are aging. Pipe networks lose an estimated 30% of treated water before it reaches consumers. Wastewater systems need upgrades. Aquifers are being drawn down faster than they’re replenished. The infrastructure investment gap runs to tens of billions of dollars annually, and federal and state budgets can’t close it alone.
At the same time, the communities your systems serve are increasingly vocal about water security, affordability, and environmental quality. Demonstrating measurable progress on those fronts matters, not just for constituent trust but for long-term resilience planning.

Blu Diamond connects your projects to private capital without raising rates.
Blu Diamond converts verified water savings from your infrastructure projects into Blu Diamond Water Certificates sold to corporate water users and institutional investors. The result is a new, non-dilutive revenue stream that reaches your project without additional municipal debt, rate increases, or dependence on uncertain grant cycles.
Eligible projects include non-revenue water leak repairs, wastewater reuse and recycling, aquifer recharge, and direct potable reuse upgrades. Cumulus monitoring infrastructure provides the continuous, independently auditable measurement that makes certificates credible to buyers.
