Overview

• In year-to-date figures, authorities report 153 sinkholes across the capital, including 37 on primary roads and 116 on secondary roads, surpassing the 130 total recorded in 2024.
• Two large collapses on Calzada Ignacio Zaragoza are under repair, with one slated to finish in under 15 days and the other in under a month, according to Segiagua.
• Segiagua describes the mechanism as collector saturation that drives water pressure up, fatigues the pipes, and leads to fissures and eventual collapse.
• In Iztapalapa’s Avenida de las Torres, nine sinkholes in a short stretch prompted an executive project for a new ~2 km collector; studies are about 80% complete, the project is expected to be ready in two months, construction would take five months, and the estimated cost is roughly 50 million pesos.
• Segiagua reports it has directly attended 23 sites, with seven more in process and six handled by the Operations Directorate; overall 108 cases have been resolved and six remain in process, while incidents on secondary roads fall under borough responsibility with technical and operational support from the agency.
