Abstract Enhancing drinking water resilience has become increasingly important. However, a comprehensive analysis of drinking water emergency countermeasures is lacking. This study evaluated eight countermeasures including monitoring, local alternatives, reclaimed water, interconnection, bulk water, pre‐packaged water, emergency treatment, and isolation valves from resilience and sustainability (i.e., life cycle cost) perspectives. While countermeasures such as interconnections perform relatively well from both perspectives, there is a clear trade‐off between resilience and cost. Local alternatives and emergency treatment respond quickly and provide sustained supply during emergencies but may incur higher costs. Bulk water and pre‐packaged water are typically inexpensive but have limited supply capacity and take time to distribute. As future threats are likely to become more frequent and prolonged, it is prudent for service providers to invest in countermeasures that perform well in both resilience and cost and use an integrated approach that combines high capital projects with bulk/pre‐packaged water contracts. 

This paper presents a serious game that simulates a water crisis triggered by the spill of an unregulated chemical. The game includes five stakeholder roles representing a chemical manufacturer, resident, water treatment plant, environmental agency, and health department, in addition to a facilitator role. The game seeks to provide players with practical experience of the communication and collaboration needed among different stakeholders to prepare for and respond to water contamination emergencies. Initial findings from game sessions with 41 participants suggest that frequent, proactive, and transparent communication can expedite the decision-making process and resolve the crisis more effectively. The game results also reveal challenges in inter-organizational coordination and communication, highlighting the need for training and standardized communication terminologies and protocols.
