According to him the system is currently stronger and more resilient to an eventual drought Water security also comes from the fact that the systems are interconnected which allows the transfer of water between reservoirs
The other springs have better levels It is necessary to replenish the water reserve in the soil soaking it first before starting to store it The advantage is that the rainfall patterns are different in the springs It rains less in Cantareira but it rains in Serra do We have advantages but we cannot relax exemplifies Giansante
This Tuesday the Rio Grande system has 983 of the storage volume São Lourenço 90 Guarapiranga 73 Cotia 568 Alto Tietê 485 and Rio Claro 445 Together the seven systems account for 461 of the water reserve capacity
Sabesp has a scale to measure the useful volume of reservoirs The spring is in a normal state when the volume is equal to or greater than 60 attention state with volume equal to or greater than 40 and less than 60 on alert above 30 and below 40 and in restriction greater than 20 and less than 30 The reference measurement is the last day of the month
According to projections by Cemaden National Center for Monitoring and Alerts for Natural Disasters considering a hypothetical scenario of rainfall in the historical average from October 2021 to April 2022 the average flow in Cantareira could be around 81 of the average in the period and the storage in the system at the end of April could reach.
