São Paulo's water will now be watched hour by hour

São Paulo's water utility is fitting 4.4 million connected meters across the city and São José dos Campos, the largest smart water-metering project of its kind anywhere. Each meter reports every hour, so families get a WhatsApp alert the moment usage spikes, often a leak hiding inside the home. The utility loses nearly 30% of its treated water to leaks and fraud; this is its bid to win that water back.
