Guandu Pipeline Rupture Floods Station, Rio Water Service Begins Gradual Recovery

Overview

• A ruptured valve on a treated‑water line from ETA Guandu to the Marapicu reservoir flooded the pump area, submerging equipment and forcing a shutdown of the elevatórias.
• Water production fell to about 50% during the incident, with Cedae completing emergency repairs around 2 a.m. Thursday and confirming full operational capacity at 7:31 a.m.
• Supply was disrupted across Rio and the Baixada Fluminense, with Rio+ Saneamento reporting a halt in service in parts of the West Zone and Águas do Rio citing impacts in multiple municipalities.
• Águas do Rio projects service normalization in roughly 24 hours for much of the city, with 72 hours or more in higher or more distant areas of the Baixada as the network refills.
• Authorities urge residents and businesses to conserve water during stabilization, as on‑site videos showed strong currents flooding nearby streets and inundating an ambulance.
