To ensure reliable access to clean water across 375 municipalities in São Paulo, Brazil, SABESP initiated a project to integrate water supply, sewage, and sanitation data in a single digital environment. Known as Integra 4.0, the program is an operational management model, combining business intelligence with AI for proactive network monitoring and maintenance to quickly identify and resolve system issues. Faced with land use, technical, and coordination challenges on a short timeline, SABESP needed integrated hydraulic modeling and analysis software to develop their systemic approach.  Leveraging OpenFlows applications, SABESP modeled hydraulic project, and monitored leaks and wasted resources, enabling integrated, accurate, and efficient management of water resources and assertive maintenance of network infrastructure. Establishing an open, connected hydraulic modeling and data environment has already resulted in a 29% reduction in water losses. Within a seven-month period, the digital solution saved approximately BRL 3.1 million in corrective maintenance, achieving a 30% reduction in corrective services to save 2,800 hours in field work, while also reducing carbon emissions.
