DAVAO CITY, Philippines — Following a catastrophic structural collapse that claimed lives and destroyed homes, national regulators are prepared to halt operations at the city’s primary waste facility. The Department of Environment and Natural Resources (DENR) is actively considering the formal suspension of the sanitary landfill in Barangay New Carmen, Davao City, after a massive garbage mound collapsed earlier in the week.
The fatal trash slide occurred past 1:00 p.m. on Wednesday, May 20, following consecutive days of relentless torrential rain that oversaturated the landfill’s structural core.
The localized disaster triggered an immediate humanitarian emergency as thousands of tons of unstable waste slid down the facility’s steep embankments, burying a nearby residential cluster:

Search and retrieval teams from the Bureau of Fire Protection (BFP), 911 Urban Search and Rescue, and the City Engineer’s Office (CEO) have been working around the clock. Rescuers are carefully digging through the unstable, water-logged debris in hopes of locating two missing elderly women. Ground access remains highly restricted because the CEO officially designated the perimeter as “unsafe for full entry,” triggering an initial temporary halt to municipal waste disposal lines.
The DENR revealed that the fatal slide was not an unforeseen act of nature. The Environmental Management Bureau (EMB) in Region 11 had been monitoring the facility closely since January, documenting a series of critical regulatory failures:
- The March Notice: In March 2026, the EMB issued a formal Notice of Violation against the landfill for operating completely without a valid wastewater discharge permit, failing to meet state effluent quality standards, and maintaining an inadequate leachate treatment system.
- The April Review: During a technical conference on April 29, the Davao city government agreed to pay administrative penalties and draft an immediate pollution control program.
- Structural Red Flags: Prior field inspections explicitly documented dangerously steep waste slopes, a collapsed leachate containment pond, and the presence of informal waste pickers living in makeshift dwellings inside the facility’s immediate hazard zone.
The structural failure underscores a broader waste management crisis for the rapidly expanding southern metropolis, which generates hundreds of tons of refuse daily:

Environment Secretary Juan Miguel Cuna emphasized that the tragedy must serve as an immediate turning point for regional urban management, stating that operations will remain frozen until extensive engineering fixes are verified.
“Every life lost is unacceptable. The DENR and the local government have been working together on the technical and regulatory requirements for months. This incident reinforces the need to accelerate slope stabilization and the safe closure plan. Operations at the landfill will not resume until the site is declared safe.” — Juan Miguel Cuna, Environment Secretary
To support the displaced families and local emergency workers, the Office of the Vice President has deployed a specialized food truck to provide hot meals at the primary evacuation center. Local officials are facing intense scrutiny over why families were still allowed to live within the 200-meter hazard buffer zone despite repeated municipal warnings to relocate—raising critical questions about structural enforcement as the region enters the highly unstable rainy season.
