ABSTRACT

Water supply and sanitation are carried out by three major types of water infrastructure for drinking water treatment and distribution, wastewater collection and treatment, and storm water collection and management. Their sustainability is measured by resilience against and adaptability to an evolving factor; here, it refers to the change of climate and its hydrological impacts. The term resilience is defined as the ability to repair and recover its physical state and service function under the impacts of external forces (McDaniels et al. 2008; Milman and Short 2008). In this context, capacity reserve (CR) is one very important physical attribute of the system’s resilience; further details will be described later in this section and in Section 12.2. While the service function of a water infrastructure varies geographically
