Locals pointed out that the heavily blocked channel restricted drainage, worsening floods in surrounding neighborhoods.
Residents warned that the standing, waste-choked water placed ground-floor households and manual cleanup crews at high risk for waterborne illnesses like leptospirosis.
While city officials cited that much of the garbage floated in from neighboring localities and Manila Bay, residents stressed that the recurring crisis demands urgent action.
Local community members called for stricter anti-littering enforcement, better waste management, and permanent structural repairs to prevent future blockages.
Most interviewed residents supported calls for neighboring local government units to improve their waterway systems to protect downstream communities.
To recall, cleanup crews from the Metropolitan Manila Development Authority ultimately collected three weeks' worth of trash from the channel and its pumping station over three days, while local officials noted that prior river dredging helped floodwaters subside faster despite the severe clogging.
