Abstract
The coronavirus pandemic outbreak is constantly changing the way of people's life. To minimize or stop the transmission of the virus, several different measures have been taken by countries worldwide and including in Ethiopia. The World Health Organization (WHO), the Ethiopian Ministry of Health, and the Ethiopian Public Health Institute recommended frequent hand wash with soap and water as one of the prevention measures for the transmission of the COVID-19 pandemic. Conversely, the provision of water supply, sanitation, and hygiene is the main problem in developing countries. After the COVID-19 outbreak, the water related challenges exacerbated the situation before the pandemic existed. Accordingly, the additional supply of water is required to sufficiently provide water for hand wash. This paper mainly addresses how much additional water is required daily for domestic consumption after the coronavirus pandemic by educational institutions, Adama Science and Technology University as a case study. The data was collected with a questionnaire by the randomly selected respondents and analyzed by SPSS (Statistical package for social sciences).The analysis shown that the consumption of water has been changed after the Corona virus (COVID-19) pandemic existed. The highest percentage of the responses to the questionnaire, more than 35% require water (2-5) liters per day and more than 60% of the respondents need additional water up to 5 L per day after the pandemic existed. Based on the analysis, total daily water use by the institute before the COVID-19 existed was 24.2 m(3)/day. These amounts of water not sufficiently satisfy the daily water requirements of the institution even before the pandemic. After the pandemic existed, the water consumption drastically increased to 29 m(3)/day. Furthermore, the study recommends the provision of additional water supply sources or water demand management to reduce the impact of the pandemic on water availability.
