The Impact of Covid-19 to Domestic Water Usage and Rainwater Harvesting at an Office Building in Jakarta

COVID-19 transforms many social fabric and people adopt new lifestyle due to the pandemic. It compels people to regularly wash their hands which lead to increasing water demand. The research on an office building in Central Jakarta, Indonesia, during 2018 - 2020 indicates 31.23 % increase in water demand per capita per day. The pandemic also reduces the effectiveness of the building’s rainwater harvesting (RWH) system because people require more water while its RWH remains unchanged. Note that the last sentence cannot be applied universally or in absolute manner due to the variability of annual rainfall and the difference in buildings’ characteristics.
