EN This work presents the results of the analysis of changes in water demand for two selected water companies in Poland caused by the SARS-CoV-2 virus pandemic (first wave). Literature that's been published so far has been broadly cited in this work, together with selected evidence collected worldwide. The aim of this article is to evaluate the impact of this type of event on the spatial distribution and variability in water demand using GIS software for two selected samples. The resulting geo-statistical analysis allowed to show areas of greatest variability in water demand using measurements from water meters. In order to achieve this the following research tools developed by ESRI were utilised: 'Space Time Cube', 'Emerging Hot Spot Analysis' and 'Local Outlier Analysis'. Indicators of space-time trend were calculated by category using the ArcGIS Pro software. Additionally the knowledge base was expanded with results of a survey conducted in Poland on hundreds of water utilities concerning impacts of the pandemic related changes in how they function, their financial liquidity, threats, and challenges. Interesting conclusions from the obtained results were presented and directions of future research in connection to further development of the situation in the world were considered. Given the lack of possibility to reference events of this type from the past, this analysis should be treated as an introductory research of this issue in Poland.
