In La Vigie, a site previously cleared of homes has reportedly become an “open-air landfill” containing car carcasses, appliances, and construction debris, posing safety risks to local children. Similarly, in Matadi, Congo, refuse accumulation near Lumumba Stadium is obstructing gutters and overflowing onto roads, raising concerns about water drainage and structural damage. In Tunja, Colombia, the utility company Veolia Aguas de Tunja warned that improper disposal of plastics, organic matter, and construction debris is obstructing sewers and inspection wells, which reduces hydraulic capacity and increases flooding risks.

Local stakeholders in Puerto Vallarta are calling for increased municipal surveillance and the enforcement of ecological regulations to address these hygiene issues. ## Timeline ### 2026-10-03: Waste management issues reported in Tunja and Puerto Vallarta Waste management issues are causing urban challenges in Tunja, Colombia, and Puerto Vallarta, Mexico, involving sewer blockages and improper disposal of heavy debris. 2 sources. https://clstr.news/cluster/waste-management-issues-reported-in-tunja-and-puerto-vallarta ### 2026-09-27: Waste accumulation issues reported in La Vigie and Matadi Residents in La Vigie and Matadi are reporting severe issues with illegal waste dumping and overflowing refuse in vacant sites and near public infrastructure, raising safety and sanitation concerns. 2 sources. https://clstr.news/cluster/waste-accumulation-issues-reported-in-la-vigie-and-matadi --- Cite as: Global urban waste management and sanitation issues.
