Abstract

In order to supress the COVID-19 global pandemics in 2020, strict measures, which limited numerous activities and movement of people at the global level, including Croatia, were introduced. The paper analyses the impact of introduced limitations on the water demand per individual consumer categories (households, economy) based on data collected for 17 water services providers in the Republic of Croatia. The data for the continental and coastal (tourism-oriented) parts of the country were equally represented. The conducted analysis looked at water consumption in 2020 in relation to average consumption values in the previous 5-year period. The changes regarding the shares of individual categories in the total consumption were detected, and conclusions and recommendations were offered in relation to the need for gaining a critical insight into the 2020 data when developing projections within the water demand analysis. An indicative example was also used as a demonstration of the impact of changes in the 2020 water consumption on the determination of (hydraulic and biological) loads on waste water treatment plants.
