The municipality of Nova Iguaçu is addressing flood prevention and drainage infrastructure through both planned development and emergency mitigation. To combat historical flooding, the city is advancing a project to build the largest stormwater reservoir system in Rio de Janeiro. This initiative involves constructing four new reservoirs and revitalizing a fifth to provide a total capacity of 346.09 million liters. The project, which aims to benefit over 100,000 residents, is seeking R$ 49 million in funding from the Novo PAC program following land cession negotiations with the utility company Light. Simultaneously, local authorities have reported escalated concerns regarding damage to the existing municipal drainage network caused by the R$ 14 billion expansion of the Via Dutra highway.
