Enterprise SaaS • Water Impact Reporting

Turn basin outcomes into audit-ready reporting—and environmental credits.

Shoalwater connects nature-based stormwater infrastructure (GSI) to enterprise reporting. Measure, verify, and disclose place-based outcomes across portfolios—then issue Storm Water Credits (SWCs) as environmental credits derived from verified performance.

Why

Why water now

Water is entering the balance sheet. Disclosure pressure, local physical risk, and existing infrastructure are converging—making verified basin outcomes a new enterprise system of record.

Disclosure is expanding

Teams need auditable, location-specific evidence that can survive stakeholder scrutiny and reporting cycles.

  • Disclosure workflows
  • Portfolio consistency
  • Reviewable records

Physical risk is local

Stormwater, flooding, and scarcity aren’t evenly distributed. Water is basin-specific and infrastructure-driven.

  • Catchment constraints
  • Facility locality
  • Place-based outcomes

Infrastructure already exists

Cities and communities invested heavily in GSI, but performance is rarely documented over time.

  • GSI programs
  • Distributed systems
  • Outcomes not connected
The gap
Water outcomes are real—but not connected to enterprise reporting or finance.
Shoalwater closes the gap

How

From basin to balance sheet

Shoalwater connects nature-based infrastructure to enterprise disclosure—so outcomes are measurable, auditable, and fundable.

Activate infrastructure

Start with what exists: cisterns, rain gardens, green roofs, retention systems, and GSI programs.

  • Program + private systems
  • Distributed portfolio coverage
  • Basin-level coordination

Document performance

Conservative accounting + reviewable evidence turns infrastructure activity into auditable outcomes.

  • GIS + locality constraints
  • Conservative boundaries
  • Evidence packets

Report + fund outcomes

Verified outcomes flow into reporting workflows and stewardship procurement—producing SWCs as environmental credits.

  • Disclosure outputs
  • Procure-and-retire credits
  • Local basin benefit

SWCs

Environmental credits derived from verified outcomes

SWCs are issued from documented performance—grounded in locality, time, and conservative accounting.

What an SWC includes

  • Named basin + locality constraints (where the benefit occurs)
  • Time-bound performance period (when the benefit occurs)
  • Conservative assumptions + boundaries (how it’s counted)
  • Reviewable evidence packet (why stakeholders can trust it)

Procure & retire

Partners purchase SWCs to support basin improvements and receive receipts suitable for internal and external reporting.

Trust

Designed for disclosure

Built to withstand stakeholder scrutiny with transparent documentation and conservative methods.

Transparent methods

Clear assumptions, boundaries, and locality constraints—so claims remain reviewable and conservative.

  • Explicit assumptions
  • Boundary clarity
  • Change logs

Evidence packets

Receipts include documentation that stakeholders can inspect: records, maps, and performance summaries.

  • Install & O&M records
  • GIS overlays
  • Time-bound summaries

Conservative accounting

Prefer under-claiming to over-claiming; align units to volumetric accounting suited to water outcomes.

  • Conservative defaults
  • Review workflows
  • Audit readiness
FAQ

Common questions

Short answers for enterprise teams evaluating reporting + environmental credit pathways.

Are SWCs offsets?
SWCs are environmental credits derived from verified basin outcomes with locality and evidence. They’re designed to be disclosure-safe and grounded in real infrastructure performance.
What data sources do you use?
Shoalwater can incorporate program records, system metadata, GIS context, maintenance documentation, and (where available) sensor or monitoring inputs—assembled into reviewable evidence packets.
Which teams buy this?
Typically sustainability/ESG reporting, corporate stewardship, risk teams, and operations leaders who need place-based evidence and consistent reporting across facilities or portfolios.
What do we get each quarter?
A reporting package: basin outcomes summary, credited units, locality documentation, and supporting evidence (maps/records) suitable for internal governance and external stakeholders.
Ready to pilot basin-level reporting?
Start with a single catchment and expand across your portfolio.
