Even with the increase in rainfall recorded in some Brazilian regions since October last year, six out of the 10 most populous states in the country began 2022 with water reservoirs at levels below those of last year. According to a survey carried out by news website Poder360, the state of São Paulo is among those in the most critical situations. For instance, the Cantareira reservoir system supplies over half of the households in Greater São Paulo and is currently at 30 percent volume — ‘normal’ levels are deemed to be above 60 percent.
State sanitation company Sabesp says there is no risk of shortages, but urges the population to use water responsibly. The firm expects reservoir levels to swell in the traditionally rainy months of January and February.
The states of Rio de Janeiro, Rio Grande do Sul, Santa Catarina, Pernambuco, and Ceará have also seen water supply levels fall between last year and now.
