This paper sets forth key concepts and advances working definitions for sustainable and resilient infrastructures (S&R-Infra), specifically for water systems. Three water infrastructure scales, such as large, medium, and small scales are considered, each of which is represented by water resource system, regional water and wastewater infrastructure, and local water distribution system, respectively. All three scales are interconnected each other since water travels from sources to end users and returns the other way. This study is beneficial by suggesting indicators to evaluate system sustainability and resilience against outer disturbances. After S&R definitions and potential indicators are provided, application examples are examined to demonstrate the applications of the proposed indicators. Application results show that the proposed indices are useful for quantifying water system performance. While the approach is refined and applied to synthetic cases, it may be considered applicable to real-world systems as system performance indicators and/or system planning and design goals within an optimization framework.
