This Rapid Response Research (RAPID) grant will demonstrate how drinking water services provided by water utilities have been impacted by the social distancing policies undertaken by much of the nation during the 2020 coronavirus pandemic. By design, social distancing policies have caused immense change in human behavior, as families shelter in place and industrial and commercial sectors pause operations. One of the many consequences of these changes is a significant spatial, temporal, and volumetric change in water use within municipal water distribution systems. These changes have the potential to substantially impact water age and water quality both within the distribution system and within homes and other buildings. In addition, utilities are facing unprecedented workforce, financial, and logistical challenges because of the pandemic as they respond to the unknown and emerging consequences of social distancing policies. As such, this research has the potential to prevent infrastructure asset damage and negative public health impacts in communities with piped water that have undertaken social distancing. Accordingly, and, as warranted by results, this project will create technical guidance for utilities to proactively mitigate these potential negative consequences.In this research, existing water meter data and new interview data will be used to identify changes in water use patterns associated with various social distancing regimes. Next, the impacts of these changes on the pressure and water quality in distribution systems will be evaluated via hydraulic modeling and water quality sampling and analysis. The hydraulic modeling will identify and locate potential water distribution problems in a university campus, a residential neighborhood, and a primarily commercial, urban downtown. These data, coupled with physical, chemical, and microbiological water quality analyses, will provide vital new empirical knowledge of water infrastructure performance under social distancing conditions. Interview data from utilities around the nation will further validate findings and enable the generalization of results and potential mitigation strategies. In partnership with collaborating water utilities, these combined datasets will be integrated to create a range of possible future Impact Scenarios of social distancing for water distribution systems. The empirically validated hydraulic models will be used to determine the implications of each Impact Scenario on distribution system performance, and to test mitigation strategies that utilities can implement during anticipated future waves of the pandemic and social distancing. Broadly, this research builds engineering theory to link human patterns of water use to the performance and resilience of water distribution infrastructure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项快速反应研究（RAPID）拨款将展示自来水公司提供的饮用水服务如何受到2020年冠状病毒大流行期间全国大部分地区采取的社交距离政策的影响。通过设计，社交距离政策已经引起了人类行为的巨大变化，因为家庭庇护到位，工业和商业部门暂停运营。这些变化的许多后果之一是城市配水系统内用水的显著空间、时间和体积变化。这些变化有可能对供水系统以及家庭和其他建筑物内的水龄和水质产生重大影响。 此外，由于疫情，公用事业公司在应对社交距离政策的未知和新出现的后果时，正面临前所未有的劳动力、财务和物流挑战。 因此，这项研究有可能防止基础设施资产损坏和对社区公共卫生的负面影响，这些社区的自来水已经进行了社会距离。 因此，根据研究结果，本项目将为公用事业公司提供技术指导，以主动减轻这些潜在的负面影响。在本研究中，现有的水表数据和新的访谈数据将用于识别与各种社交距离制度相关的用水模式的变化。接下来，将通过水力建模和水质采样和分析来评估这些变化对配电系统中压力和水质的影响。水力模型将确定和定位潜在的水分配问题，在大学校园，住宅区，主要是商业，城市中心区。这些数据，再加上物理，化学和微生物水质分析，将提供重要的新的经验知识的水基础设施的性能在社会距离的条件下。来自全国各地的公用事业公司的访谈数据将进一步验证调查结果，并使结果和潜在的缓解策略的推广成为可能。通过与合作的水务公司合作，这些组合数据集将被整合，以创建一系列未来可能的配水系统社会距离影响情景。经经验验证的水力模型将用于确定每个影响情景对配电系统性能的影响，并测试公用事业公司在预期的未来大流行和社交距离浪潮中可以实施的缓解策略。 从广义上讲，这项研究建立了工程理论，将人类用水模式与供水基础设施的性能和恢复力联系起来。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
