Small Drinking Water Utilities' Resilience: The Case of the COVID-19 Pandemic

ABSTRACT

Extreme events can significantly disrupt the operation and maintenance (O&M) of drinking water utilities (DWUs), compromising community access to water in critical times. However, we posit that utility size can influence DWUs' resilience, as large DWUs may have a greater capacity to handle extreme and sudden changes characteristic of emergencies. Here, we explore the resilience of small DWUs by understanding how a global crisis (i.e., the COVID-19 pandemic) affected small DWUs and how these impacts statistically differ from those of large DWUs using statistical inferencing. We used two data sets that reflect the perspectives of 28 large and 26 small DWUs from 14 states. We found that small DWUs experienced issues involving supply chain, finances, and personnel management that pre-existing issues may have magnified. Additionally, small and large DWUs experienced statistically significant differences in personnel management, revenue change, increase in delinquent accounts, and emergency response plan activation. For example, large DWUs experienced more revenue loss than small DWUs due to economies of scale and larger changes from status quo operations. This study reveals areas of concern (and opportunities) regarding the resiliency of small DWUs in the face of emergencies that can allow policymakers to assist small DWUs. © 2023 American Chemical Society.
