Early in the morning, the floating trash trap in Barangay Balong Bato, San Juan City, was already heavy with plastic bottles, food wrappers, and other waste drifting along the water. The sight has become alarming for nearby residents who fear clogged waterways and possible flooding if the garbage continues to pile up.
In response, the Department of Environment and Natural Resources (DENR) Metropolitan Environmental Office–West moved quickly after receiving a report from the Quick Response Team of DENR National Capital Region about the worsening garbage buildup.
A meeting was immediately called and led by OIC Director Rodelina M. De Villa. Representatives from the Environmental Management Bureau–NCR, the Pasig River Coordinating and Management Office (PRCMO), and the San Juan City Environment and Natural Resources Office (CENRO) also attended. Officials discussed the growing volume of waste trapped in the floating barrier and the urgent need for a more systematic solution.
The floating trash trap is designed to catch garbage before it flows further downstream. However, authorities noted that the amount of waste being collected has increased significantly in recent weeks. This suggests that more trash is entering the waterways from upstream communities.
To address the issue, the group agreed to conduct a series of clean-up drives in the affected area. They also plan to coordinate with the Metropolitan Manila Development Authority (MMDA) and the Department of Public Works and Highways (DPWH) for additional manpower and logistical support. Officials believe stronger inter-agency cooperation is key to sustaining the clean-up efforts.
As part of its immediate action plan, MEO–West carried out an ocular site inspection from February 16 to 23, 2026. The inspection aimed to identify possible upstream sources of the waste. Areas visited included Barangay Salapan in San Juan City and Barangays Damayan, Tatalon, and Doña Imelda in Quezon City.
During the inspection, authorities identified waterways that may need additional floating trash traps and other interventions. By placing barriers closer to the source, officials hope to prevent large volumes of garbage from reaching Barangay Balong Bato.
MEO–West stressed that solving the problem requires more than removing trash from one location. It is important to identify and address the “upstream sources” of waste. Proper solid waste management at the community level plays a major role in preventing garbage from entering esteros and rivers.
Uncollected waste in waterways can block drainage systems and increase the risk of flooding, especially during heavy rains. It can also lead to water pollution and the spread of diseases. Metro Manila has long struggled with waste management challenges, and authorities say consistent enforcement of waste segregation and proper disposal is necessary.
Local government units are encouraged to strengthen community awareness campaigns and enforce existing environmental laws. Residents are also reminded to dispose of waste properly and avoid throwing garbage into canals and rivers.
The DENR said it remains committed to protecting urban waterways and improving environmental conditions in Metro Manila. But officials emphasized that long-term success depends on cooperation among national agencies, local governments, and the public.
As the city continues to grow, responsible waste management becomes even more urgent. Keeping rivers clean is not only about appearance. It is about safety, health, and the future of communities living along these waterways.
