The Alto Tietê Water System (SPAT) in Brazil has reported a stabilization in water levels after experiencing consistent increases in early February. According to the data provided by the São Paulo State Basic Sanitation Company (Sabesp), the water volume variation was minimal, with only a 0.5% increase observed over the past week. As of February 13, the reservoirs were at 38% capacity, and this slight increase to 38.5% as of February 20 indicates a positive trend for the month, especially considering that 72% of the anticipated rainfall has occurred during this period.

As rain has contributed significantly to maintaining water levels, the SPAT has recorded 127.3 millimeters of precipitation, slightly below the expected 176.8 millimeters. This consistent rainfall has been beneficial, ensuring that there have been no declines in water volume over the last 34 days, which is crucial for the reservoirs that supply water to over 4.5 million residents in the region. The situation is encouraging, as it presents a steady scenario for the water management authorities in the area.

Overall, the scenario reflects a cautious optimism regarding water management in the São Paulo region, particularly given the historical challenges faced during dry seasons. The stability in the Alto Tietê System can alleviate some concerns about water supply for the local population, while also emphasizing the importance of continued monitoring of rainfall and reservoir capacity to ensure a sustainable water supply in the future.
