In the Cai N’Água neighborhood, the revitalization of the Santa Bárbara canal has entered a new phase involving the installation of two-meter diameter pipes and containment boxes to enhance water flow. This work is being conducted by the Municipal Infrastructure Secretariat (Seinfra) with support from the Companhia de Águas e Esgotos do Estado de Rondônia (Caerd). Additionally, in the Três Vendas district, the Department of Urban Drainage has started installing 1,000-millimeter diameter concrete pipes on Avenue 4 within the Getúlio Vargas allotment. These upgrades are intended to direct water toward the collector canal near Lobão Park, providing a flow capacity of approximately 3,000 liters per second to address drainage issues caused by recent rainfall. ## Timeline ### 2026-08-31: Porto Velho advances urban drainage and canal revitalization projects Porto Velho is advancing urban drainage projects, including the installation of large-diameter pipes in the Cai N’Água and Getúlio Vargas areas to improve water flow and prevent flooding. 4 sources. https://clstr.news/cluster/porto-velho-advances-urban-drainage-and-canal-revitalization-projects ### 2026-08-11: Ilhéus Mayor seeks faster project approvals and advances drainage works Ilhéus Mayor Valderico Júnior is pushing for faster project analysis to boost construction, while the city advances a drainage canal project in Teotônio Vilela to prevent flooding. 3 sources. https://clstr.news/cluster/ilhus-mayor-seeks-faster-project-approvals-and-advances-drainage-works --- Cite as: Urban drainage infrastructure projects in Porto Velho.
