Overview

• A georadar survey uncovered a second cavity less than 100 meters from Guadalajara’s first July 4 sinkhole on Avenida Malecón, prompting plans to excavate, replace about six meters of collector pipe and reconstruct the surface.
• Malecón repair works reached 95 percent completion by July 7 and are expected to reopen to traffic by July 11.
• In San Pedro Tlaquepaque’s La Duraznera, SIAPA has replaced two of seven segments of a 48-inch pluvial and sanitary collector since July 6 and will continue phased replacements as weather permits.
• Protección Civil de Iztacalco has cordoned off the median on Circuito Interior Río Churubusco after two five-meter-deep sinkholes appeared this week, closing one central and one lateral lane at Oriente 106 pending trench stabilization.
• These recurring incidents highlight how decades-old drainage and sewer systems, some over 50 years in service and lacking regular maintenance, are vulnerable to leaks, heavy rains and urban growth.
