다국어 초록 (Multilingual Abstract)

Objectives : The objective of this research is to evaluate how the COVID-19 pandemic spread and prevention actions are affecting water consumption pattern in the domestic small-medium sized city. Also, the main contribution is the assessment of water consumption during a pandemic, proving information for management of water supply system in order to be resilient in challenging situation for the community.
Methods : In this study, data on the water consumption by administrative subdivisions and uses were obtained from January 2018 to December 2020. The water consumption can be divided into the uses for household, office, business and public bath. Data were analyzed in a time series from 2018 to December 2020 in 35 administrative subdivisions.
Results and Discussion : As a result of analyzing the consumption pattern of tap water by use in domestic J_city, the consumption of household water tends to increase slightly, but it is found that the trend of change in office, business and public bath water is not significant.
Conclusion : It can be seen that the consumption of households in 2020 is slightly higher than in 2018 and 2019, and the consumption of water for business, business and public baths has decreased. Probably, as homework and non-face-to-face classes of students increase, consumption of household water increases and consumption of business and business water decreases.

목적: 본 연구의 목적은 인구 약 300,000명 정도 국내 중소도시를 대상으로 코로나-19 대유행으로 인해 야기된 시민들의 행동 및 생활의 변화가 수돗물 소비에 미치는 영향을 평가하고자 하였다.
방법: 본 연구에서는 2018년 1월부터 2020년 12월까지 행정동별, 용도별, 시민들의 수돗물 사용량 데이터를 입수하였다. 수돗물의 용도는 가정용(household), 업무용(office), 영업용(business) 및 대중탕용(public bath)으로 구분하고 있다. 월 데이터를 이용하여 동, 읍 및 면단위로 35개의 행정소구역의 2018년부터 2020년 12월까지 데이터를시계열로 분석하였다.
결과 및 토의: 연구 대상인 국내 J_도시의 용도별 수돗물 소비패턴을 분석한 결과 가정용 용수의 사용량은 미세하게 증가하는 경향을 보이고 있으나 업무용, 영업용 및 대중탕 용수는 변화 추이가 크지 않는 것으로 조사되었다.
결론: 가정용은 2020년의 소비량이 2018년과 2019년에 비해 약간 높은 것을 알 수 있으며, 나머지 업무용, 영업용및 대중탕용수는 소비량이 감소하는 것으로 나타났다. 아마도 재택근무와 학생들의 비대면 수업이 증가하면서 가정용수의 소비는 증가하고 업무용 및 영업용수의 소비는 감소하는 것으로 판단된다.
