Overview
IEC SRD 63301-2:2025 - "Smart city use case collection and analysis - Water systems in smart cities - Part 2: Use case analysis" is a Systems Reference Deliverable from the IEC Smart Cities committee. This part develops structured use cases derived from user stories, organized into a database for analysis to scope out standard requirements - in particular electro-technical standards for IEC and other Standard Development Organizations (SDOs) related to urban water management. The document supports harmonized, standards-based approaches to water security, supply resilience, drainage, flood prevention and integrated urban water-cycle operations in smart cities.
Key topics
The standard focuses on practical, analytical elements rather than prescriptive technical specifications. Major topics covered include:
- Use case stratification: business cases, high-level use cases (HLUCs) and specialized use cases.
- Use case analysis approach: methods to transform user stories into analysable use cases and database entries.
- Use case derivation across water domains:
- Water resource protection and preservation
- Robust water supply
- Water drainage systems
- Resilience-based urban flood prevention and control
- Flood management, control and relief
- Integrated urban water cycle management
- Intelligent manhole cover monitoring systems
- User stories and coding: standardized formats and coding for consistent capture.
- Application of the analysis: translating use case outputs into a standards hierarchy and standard recommendations (business, technology, management, service standards).
- Alignment with higher-level goals such as the UN Sustainable Development Goal 6 (water and sanitation).
Applications
IEC SRD 63301-2:2025 is intended to be a practical tool for:
- Scoping and prioritizing electro-technical standard requirements for water systems in smart cities.
- Building use-case databases to inform requirements engineering, interoperability and conformity assessment.
- Supporting the development of technical specifications and guidance for sensing, control, communications and management systems used in urban water infrastructures.
- Informing resilience planning for water supply, drainage and flood mitigation across municipal and regional programs.
Who should use this standard
- National and international standard developers and SDOs seeking harmonized requirements.
- City planners, municipal water utilities and infrastructure operators designing smart water programs.
- Systems integrators, solution architects and vendors of ICT/electrotechnical products for water management.
- Policy makers, researchers and consultants working on urban resilience, sustainability and SDG6 implementation.
