If you do only one thing, collect rain water.

How Shoalwater turns rainwater outcomes into credible, place-based impact

Shoalwater bridges corporate water stewardship and basin-level outcomes by verifying decentralized rainwater harvesting and green stormwater infrastructure (GSI) performance over time—then translating that performance into Storm Water Credits (SWCs) that fund healthier waterways and community benefit.

Capture rain where it falls

We activate decentralized systems—cisterns, rain gardens, retention and other GSI—so runoff is reduced at the source and basins perform better over time.

  • Support household, community, and commercial systems
  • Reduce peak flows and combined sewer overflow risk
  • Improve basin-wide resilience and water quality outcomes

Verify real performance

We document outcomes with conservative methods and reviewable records—so partners can back credible, place-based water benefit without vague claims.

  • Location-specific, time-bound documentation
  • Conservative boundaries and explicit assumptions
  • Reviewable records for stakeholders and reporting

Fund basin-level outcomes

Companies purchase SWCs to meet stewardship goals while targeting basins where water quality benefits are most urgent—supporting local outcomes and durable community value.

  • Targeted basins → targeted outcomes
  • Equity-forward investment pathways
  • Local stewardship and green jobs support

From outcomes to credits

Shoalwater translates verified performance into Storm Water Credits (SWCs) that help partners demonstrate measurable water benefit while increasing the return on existing green infrastructure investments.
