Severe rains in the São Francisco River basin have altered the characteristics of the water and led to a reduction in the treated water production in the Brazilian state of Sergipe. The information was released by the Companhia de Saneamento de Sergipe (Deso) and the concessionaire Iguá. They reported increased color and turbidity levels of the water, caused by sediment runoff and the presence of organic matter such as branches and leaves in the water intake system.

To ensure compliance with the potability standards established by the Ministry of Health, the Water Treatment Stations (ETAs) have intensified monitoring and made operational adjustments. This includes temporary reductions in the treatment speed and total water production. The affected municipalities include Nossa Senhora da Glória, Carira, São Miguel do Aleixo, Nossa Senhora Aparecida, Frei Paulo, Pedra Mole, Pinhão, Feira Nova (rural area), and Porto da Folha, among others, indicating the widespread impact of these environmental changes on local water supply systems.

The situation highlights significant challenges faced by water management entities in regional areas of Brazil, particularly during extreme weather events. The increased sedimentation and organic material in water sources not only complicate treatment processes but also challenge public health and access to clean water in affected areas. Authorities are expected to closely monitor the ongoing weather patterns and water quality to mitigate further issues in the supply chain.
