Overview

• The 19:00–05:00 schedule replaces the previous 8-hour window and will remain in effect until reservoir levels recover.
• Monitoring shows the Integrated Metropolitan System at 32.8% of useful volume, with Cantareira at 30.3% and Alto Tietê at 26.1% after a week averaging a 0.26-point daily drop.
• Authorities point to a prolonged dry pattern, with August totals such as 3 mm in the PCJ basins versus a 29 mm average and 11 mm in Alto Tietê versus 32 mm.
• The committee has not identified specific neighborhoods, and some areas may face punctual daytime pressure reductions in addition to the nightly program.
• The first phase launched on 27 August saved about 7.2576 billion liters by cutting leak losses, enough for more than 800,000 people for a month, according to Sabesp.
