Rain is a resource—not runoff.
Connecting distributed nature-based infrastructure into one visible, scalable basin network.
Shoalwater turns distributed Green Stormwater Infrastructure into a measurable basin network. We connect verified projects, hydrology, property-level performance, and stewardship funding so rain captured across many sites can be understood—and acted on—as one larger water system.
We do not need to invent the solution. We need to scale what already works.
Proven water infrastructure already exists across the basin—but it is fragmented, difficult to see, and disconnected from new investment. Shoalwater creates the network that makes existing projects visible, directs funding toward the strongest opportunities, and helps nature-based solutions scale across the watershed.
A measurement and delivery layer for distributed water infrastructure.
Most stormwater infrastructure is installed one property at a time, then disappears into fragmented records. Shoalwater brings those systems back into view—standardizing verified project data, modeling water performance, assigning basin context, and aggregating many small assets into one usable portfolio.
Quantify
Translate post-inspection records, roof area, system type, storage, infiltration, and rainfall into consistent water-performance metrics with clear methods and controls.
Aggregate
Link cisterns, rain gardens, green roofs, permeable surfaces, and other local systems by watershed—while preserving property consent, attribution, and data custody.
Improve
Use basin intelligence to identify where new installations, maintenance, retrofits, and community projects can deliver the strongest localized water benefit.
A local vehicle for corporate water replenishment.
Shoalwater gives sustainability teams a practical way to participate in local water stewardship. We develop basin-specific portfolios of verified nature-based infrastructure, coordinate delivery partners and participating properties, and provide evidence that supports replenishment claims, internal decision-making, and water disclosures—without positioning the work as a regulatory offset.
Match
Translate water goals, operating geography, and community priorities into a defined basin strategy.
Fund
Direct funding toward eligible infrastructure, maintenance, monitoring, and project development.
Implement
Bring together trusted contractors, property owners, and local systems into one delivery pathway.
Verify
Maintain the evidence trail: eligibility, consent, methods, modeled performance, and attribution boundaries.
Report
Package the results into decision-useful dashboards, impact summaries, and disclosure-aligned reporting.
A living signal for healthier watersheds.
The Basin Stewardship Index is Shoalwater’s measurement layer for distributed water infrastructure. It combines verified assets, modeled hydrology, basin location, system condition, and participation data into a living picture of where water is being managed, where capacity is missing, and where stewardship capital can have the greatest local effect.
Already managing rain on your property? Make that impact visible.
Shoalwater is building a verified registry of existing Green Stormwater Infrastructure across the region. Property owners can register eligible cisterns, rain gardens, green roofs, permeable surfaces, and other systems so their water impact can be quantified, attributed with consent, and represented within a larger basin portfolio.
Registration does not transfer ownership of your infrastructure or automatically enroll it in a corporate program. It creates a durable impact record and gives you control over whether the system may be included in future stewardship, recognition, maintenance, or funding opportunities.
Best suited for professionally installed or documented systems with project records, post-inspection materials, or clear system specifications.
Different roles. One shared water system.
Fund measurable replenishment
Fund place-based water stewardship tied to real infrastructure, documented methods, and reporting-ready basin outcomes.
Put your infrastructure to work
Make existing cisterns, rain gardens, and other verified systems visible within a larger basin portfolio—without giving up ownership of the asset.
Extend the value of every project
Extend the value of completed projects through durable impact records, portfolio visibility, and future maintenance or implementation opportunities.
See distributed infrastructure at scale
See distributed infrastructure as a coordinated network while keeping municipal compliance, public programs, and Shoalwater stewardship roles clearly separated.
Turn local water infrastructure into basin-scale impact.
Partner with Shoalwater to surface existing water infrastructure, build a basin-specific replenishment portfolio, or fund the next layer of distributed systems that healthier watersheds require.
