✔ MRV: AWS + VWBA-aligned 📍 Catchment-specific

Turn stormwater into smart water.

Shoalwater issues, procure-and-retire Storm Water Credits (SWCs) tied to local watersheds— so enterprise ESG teams can fund local GSI & reuse projects and report audited, place-based outcomes.

🏢 The Problem

ESG teams need place-based water impact—not generic offsets. Assembling and auditing a catchment-specific portfolio across sites and budgets is slow and messy.

💧 Our Solution

We issue Storm Water Credits (SWCs): 1 SWC = 1,000 gal credited, tied to a named catchment. We deploy GSI & reuse, then retire units on purchase and deliver a quarterly Impact Receipt.

🛡️ Assurance
  • MRV aligned to AWS governance & VWBA volumetrics
  • Annual desk audit; ~20–30% representative sites instrumented
  • Compliance-safe claims (no trading; not a security)

How it works
📍 1) Assess & Match

Map facilities to priority watersheds (e.g., Seattle guidance), baseline gallons, confirm permitting & fee-credit pathways.

🧱 2) Allocate & Deploy

Portfolio optimizer assembles cistern/reuse + GSI (rain gardens, permeable) to hit gallons, locality & budget targets.

🌊 3) Verify & Retire

Telemetry + desk MRV with conservative uncertainty → quarterly Impact Receipts. We retire SWCs upon purchase.

Compliance & Claims

SWCs are voluntary stewardship units; not securities; no secondary trading. Jurisdictional benefits vary. In Seattle, SWCs are not a tradable compliance credit; separate drainage-fee credits may apply for eligible private systems that meet code and O&M requirements.
