São Paulo Issues Water-Use Alert as Heat Wave Strains Supply

Overview

• Sabesp reports water demand up to 60% above normal and says production rose from about 66,000 to 72,000 liters per second to meet usage.
• Intermittent or prolonged outages are concentrated in higher neighborhoods of São Paulo, including parts of Butantã, and in Alto Tietê cities such as Suzano, Mogi das Cruzes and Guararema.
• Residents continue to report low pressure and multi-day gaps, with some presenting measurements at street connections despite Sabesp stating delivery is regular up to building entry points.
• Metropolitan reservoirs operate at roughly 26% capacity, down from about 48% a year earlier, increasing sensitivity to consumption spikes during the heat.
• Sabesp cites recent power cuts that affected pumping to elevated areas and says it is making operational adjustments, deploying water trucks in places like Guararema, while Arsesp processes user complaints.
