The Cantareira System, the largest water producer in the São Paulo metropolitan region, reached, this Wednesday (1st), the highest level in the last ten years, reaching 70% of its storage capacity. The last time this level was reached was on August 23, 2012. Exactly one year ago, the Cantareira operated at 43% capacity. The rains of recent months have improved the situation of all the springs that supply the metropolitan region of São Paulo, according to the report released daily by the Basic Sanitation Company of the State of São Paulo (Sabesp). Other systems in São Paulo were also operating at a normal level today, above 69% of their capacity. The only exception was the Rio Claro System, which operates with only 42.7%, in terms of attention. Adding up all the systems operated by Sabesp, the water level reached 74.2% this Wednesday. Levels Water collection from the Cantareira System is conditioned to the water storage level of the source observed on the last day of each month. Five lanes were created, defined by a joint resolution of the National Water and Basic Sanitation Agency and the Department of Water and Electric Energy, in 2017, which must be followed by Sabesp. The five levels created by the resolution are: normal, when it is equal to or greater than 60%; attention, if equal to or greater than 40% and less than 60%; alert, when it is greater than 30% and less than 40%; restriction, if greater than 20% and less than 30%; and special, when the accumulated volume is below 20%. These ranges guide the system’s water withdrawal limits. As, on February 28, the Cantareira had 69.1% of its total capacity, the system is currently operating in the normal phase.
