The Cantareira System has the lowest volume stored for the beginning of April since 2016, according to data from the Basic Sanitation Company of the State of São Paulo (Sabesp). According to an update on Tuesday (5), Cantareira has 45.6% of its total volume. In 2016, the minimum was 36.6%.
Despite the Cantareira System being the largest supplier of water to the metropolitan region of São Paulo, the rates of the other reservoirs that supply the region are not below 50%. Alto Tietê, for example, operates with a volume of 60.7%; the Rio Grande reservoir reached 103.8% of the total volume.
Considering the average of all reservoirs, the operation takes place with an average stored volume of 60.2%, according to Sabesp.

rains
Even with the Cantareira scenario, the arrival of autumn brought prospects of rain to the Southeast region — which was consolidated with large volumes of water in coastal regions and, consequently, tragedies in regions with homes in risky locations.
According to Climatempo, between the nights of March 31 and April 2, rain gauges from the National Center for Monitoring and Alerts for Natural Disasters (Cemaden) recorded more than 700 mm in the region of Angra dos Reis, on the south coast of Rio de Janeiro. In the region of Ubatuba, north coast of São Paulo, the accumulated in 48 hours reached almost 600 mm.
The perspective is that April will continue rainy and count on the passage of another intense cold front, which should arrive strong in the Southeast in the beginning of the second half of the month, warned Climatempo.
In an interview with CNN This Wednesday (6), the chief meteorologist at Inmet (National Institute of Meteorology), Francisco de Assis Diniz, said that the unusually heavy rains that have hit the country in recent months are also a consequence of ongoing climate change.
“This year’s summer [teve] very strong meteorological adversities in relation to these extreme events, which have been increasing not only in Brazil, but worldwide due to climate change”, he said. “If you warm [o planeta]creates more instability in the atmosphere, and consequently there will be more heavy rains, more storms and windstorms”, he explained.
