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 escalated concerns regarding damage to the municipal drainage network caused by the R$ 14 billion expansion of the Via Dutra highway. The City Hall has filed complaints with Ibama against the concessionaire Ecovias Rio Minas, alleging that the company performed improvised repairs, referred to locally as ‘bacalhaus’, on pipes in the Rancho Novo neighborhood. Municipal officials claim the concessionaire failed to meet a 90-day deadline set by the National Land Transport Agency (ANTT) to deliver necessary drainage studies and proceeded with paving instead of making required corrections. Authorities warn that without adequate drainage channels and galleries, the highway expansion could act as a barrier to rainwater, significantly increasing flood risks in urbanized areas. On September 30, 2026, Mayor Dudu Reina met with the ANTT to demand solutions and discuss potential contract changes for Ecovias Rio Minas. The Mayor emphasized that while the city supports highway modernization, it cannot accept improvements that create drainage issues in local neighborhoods, specifically citing inadequate micro-drainage in Posse and damaged pipes in Rancho Novo. The Rio de Janeiro Public Prosecutor's Office is currently monitoring the situation as the municipality seeks judicial intervention.
