Mismanaged plastic waste clogs urban drainage systems, turning heavy rains into devastating floods. Lightweight plastics like bags and bottles block water flow, causing rapid water accumulation and overflow.
During storms, plastic debris blocks river trash racks, causing water levels to spike up to 1 meter within an hour. This sudden rise leads to hazardous flood conditions in urban areas.
Approximately 218 million people worldwide are at increased flood risk due to plastic pollution. Cities like Mumbai, Lagos, and Manila have experienced severe floods exacerbated by clogged drainage systems.
To mitigate flood risks, cities must invest in effective waste management and infrastructure. Reducing plastic pollution is crucial to prevent drainage blockages and protect vulnerable communities from flooding.
