The Vision
Accelerating water stewardship
Shoalwater is pioneering an impact marketplace
that rewards the adoption of green stormwater
infrastructure and water conservation by valuing
rain as a regenerative resource—not a
commodity. Rather than extracting or privatizing
freshwater, Shoalwater’s model leverages
incentives and verified data to promote rainwater
harvesting as a nature-based climate solution.
This approach avoids the pitfalls of traditional
water markets, which often lead to inequity and
over extraction, and instead builds a
decentralized water economy rooted in
stewardship, access, and sustainability.

What we do
Monitor
Water stewardship
A reliable, sustainable water source starts with rain.
Discover how a smart rain water harvesting system can transform your specific property & habitat— a tailored strategy that maximizes utility, sustainability, and long-term resilience.
Rainwater collection recharges groundwater and reduces municipal water reliance
Helps mitigate drought, lower utility costs, and support climate resilience
Integrates into local systems to enhance water security and reduce runoff pollution
Empowers communities to build a sustainable, adaptive future
Water resilience is no longer optional—it’s a defining metric of ESG leadership.
Shoalwater empowers homeowners and businesses with a VWBA-aligned platform that transforms rainwater harvesting into a traceable, reportable, and verifiable sustainability asset.
Leverages IoT sensors and advanced analytics to quantify real-time water capture
Aligns with the Volumetric Water Benefit Accounting (VWBA) framework for credible, science-based validation
Provides a transparent and auditable system for monitoring, reporting, and verifying (MRV) water stewardship outcomes
Connects every drop to impact local water basins, climate resilience goals, and nature-based impact credits
