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.

W pracy przedstawiono wyniki analizy zmienności zapotrzebowania na wodę dla dwóch wybranych przedsiębiorstw wodociągowych w Polsce spowodowanych pandemią wirusa SARS-CoV-2 (pierwsza fala). Omówiono dotychczas opublikowaną literaturę oraz badania w tym zakresie realizowane na całym świecie. Celem artykułu jest ocena wpływu pandemii na rozkład przestrzenny i zmienność zapotrzebowania na wodę, przy wykorzystaniu oprogramowania GIS. Analizę wykonano dla dwóch jednostek osadniczych. Analiza geostatystyczna pozwoliła na wskazanie obszarów o największej zmianie zapotrzebowania na wodę, na podstawie analiza danych pomiarowych z wodomierzy. Do celu realizacji badań wykorzystano następujące narzędzia badawcze w pakiecie oprogramowania ESRI: "Space Time Cube", "Emerging Hot Spot Analysis" i "Local Outlier Analysis". Wskaźniki trendu czasoprzestrzennego obliczono według przy użyciu oprogramowania ArcGIS Pro. Dodatkowo baza wiedzy została poszerzona o wyniki badania przeprowadzonego w Polsce wśród setek przedsiębiorstw wodociągowych, na temat skutków zmian związanych z pandemią na ich funkcjonowanie, płynność finansową oraz zagrożenia i wyzwania związane z tego typu zjawiskami. Zaprezentowano ciekawe wnioski z uzyskanych wyników oraz rozważono kierunki przyszłych badań, w związku z dalszym rozwojem sytuacji na świecie. Ze względu na brak możliwości odniesienia się do tego typu wydarzeń z przeszłości, niniejszą analizę należy traktować jako wstępne badania tego zagadnienia w Polsce.
