President John Dramani Mahama has said that the recurring flooding in Accra is not mainly an engineering failure, but a result of indiscipline, poor waste disposal, and human interference with natural waterways.

He made the statement while speaking at a Ghana Diaspora Town Hall Meeting in London on May 31, 2026, where he addressed hundreds of Ghanaians, investors, professionals, and business leaders.

Mahama explained that although Accra has drainage systems in place, human behaviour continues to worsen flooding across the city. He said plastic waste often ends up in drains, blocking the free flow of water during heavy rainfall.

According to him, the widespread disposal of sachet water plastics and food packaging into gutters has become a major challenge, as these materials are carried into drainage channels and cause blockages.

He also pointed out that many developments in Accra are built on natural water channels and wetlands, which originally helped direct rainwater into the sea. He warned that such construction disrupts the natural flow of water and increases flood risks.

The President added that wetlands, which normally absorb excess rainwater, are being filled and built upon, removing their natural capacity to control flooding.

He further criticised land sales and construction along waterways, noting that enforcement actions by authorities often face public resistance when illegal structures are demolished.

Mahama stressed that addressing flooding in Accra requires stronger discipline, proper waste management, and strict enforcement of planning laws rather than focusing only on expanding drainage infrastructure.

His comments come amid ongoing concerns over seasonal flooding in parts of the capital, where heavy rains continue to displace residents and damage property.
