A technical inspection conducted on the Guandu system has led to a significant reduction in the output of the Water Treatment Station (ETA), decreasing operations to around 50% as of Thursday. This maintenance work affects not only the immediate area but also has broader implications for water availability throughout various municipalities in the Fluminense Baixada and across the capital of Rio de Janeiro. The State Water and Sewage Company (Cedae) has stated that inspections and tests are underway on critical infrastructure components, including pipelines, which are essential for delivering treated water to a vast portion of the Metropolitan Region.

The maintenance activities may cause disruptions in water supply for residents in several cities within the Baixada Fluminense, including Duque de Caxias, Nova Iguaçu, and others, making it imperative for local governments and water authorities to communicate effectively with the public. Additionally, residents in various zones of Rio, particularly in the North, Central, South, and West areas, may also experience fluctuations in water supply throughout the day. The expected timeframe for the inspection's completion is around 10 PM, but authorities caution that it may take up to 72 hours for the water supply levels to stabilize fully after the maintenance is concluded.

As communities depend heavily on reliable water supply, this situation underscores the importance of infrastructure maintenance in ensuring public access to essential services. The current disruption raises concerns about potential impacts on daily activities, public health, and overall quality of life in the affected regions, prompting calls for improved planning and communication during such necessary maintenance events.
