Resilient water infrastructure design brief

This design brief guides users on how resilience can be built into the engineering design of a project. With a focus on the three natural hazards most likely to affect water and sanitation infrastructure (droughts, floods, and high winds from storms), the document provides a six-step process to help users address weather and climate related challenges that are most likely to affect an infrastructure component at some point in its operational lifetime.

The paper identifies six steps to a resilient infrastructure:

1. Identify system components and conduct high-level hazard screening;

2. Understand the role of each component in the system and the consequences of failure;

3. Identify and assess component failure modes;

4. Evaluate hazard levels and compare them with component failure modes;

5. Identify component risk mitigation options;

6. Evaluate and select component risk-mitigation measures.
