Water Decisions

An open-source decision support framework that structures best practice from around the world into reusable knowledge for water infrastructure resilience.

The critical question for water decision makers is whether solutions used elsewhere will work in their context. Water Decisions addresses this by structuring real-world case studies through an AI-enabled ontological framework, decomposing them into use cases, decision patterns, and system models that can be compared, adapted, and applied.

The framework aligns with ISO 22372 and the UNDRR Principles for Resilient Infrastructure, so that structured insight can be ported into existing company systems and analytical processes.

How It Works

Case studies are structured through the framework into reusable, comparable components.

Case Studies

Best practice from 22 real-world water infrastructure projects across 15 countries — what worked, what didn't, and why.

22 published 15 countries SDG mapped

Ontology

The AI-enabled knowledge framework that structures case studies into comparable, reusable components across four domains.

4 domains 24 concepts ISO 22372 aligned

Use Cases

Operational scenarios extracted from case studies — what triggers a decision, what data is available, and what action follows.

15 scenarios Cross-linked

Decision Patterns

Proven strategies distilled from case studies — the playbook entries for common water infrastructure challenges.

17 patterns Evidence-based

System Models

How water systems behave over time — the analytical layer that turns options into projected outcomes.
