This study investigated the changes that occurred during the COVID-19 pandemic in urban water consumption in residential, commercial, industrial, and public agencies in the city of São Leopoldo, southern Brazil, which has about 55,000 consumers and over 200,000 inhabitants. Overall, the city increased water consumption by 5.6% during the 2-year pandemic, with 5.9% in 2020 and 5.5% in 2021. Residential and industrial consumption increased by 6.77 and 9.92% in the first year, and by 5.47 and 14.4 ...
This study investigated the changes that occurred during the COVID-19 pandemic in urban water consumption in residential, commercial, industrial, and public agencies in the city of São Leopoldo, southern Brazil, which has about 55,000 consumers and over 200,000 inhabitants. Overall, the city increased water consumption by 5.6% during the 2-year pandemic, with 5.9% in 2020 and 5.5% in 2021.

In addition, the water consumption during the pandemic and pre-pandemic periods was statistically different for residential, industrial, and public consumers. ...
