Why Ghanaian cities keep flooding: the hidden waste connection

WasteCure Team15 January 20265 min readEducation

Almost every rainy season, towns and cities across Ghana experience flash flooding - streets turned to rivers, homes and shops damaged, and in the worst cases, lives lost. Heavy rainfall is the trigger, but it is rarely the whole story. In most urban flooding events, blocked drains carrying solid waste are a major contributing factor.

How waste causes flooding

Drainage systems in Ghanaian towns are designed to channel rainwater away quickly. When plastic bags, bottles, food waste and other rubbish are dumped into gutters and drains instead of being collected, that water has nowhere to go. The Ghana National Disaster Management Organisation (NADMO) has repeatedly linked recurring floods in Accra, Kumasi and other urban centres to solid waste blocking drainage channels, particularly ahead of the rainy season when debris accumulates faster than it is cleared.

The cost is more than inconvenience

Flooding damages homes, destroys goods in markets, disrupts transport, and creates standing water that becomes a breeding ground for mosquitoes and waterborne disease. A World Bank assessment of environmental degradation in Ghana estimated that flooding and poor waste management together account for a significant share of the country's annual environmental and health-related economic losses.

What actually reduces the risk

The single most effective thing a community can do is keep waste out of drains in the first place - through regular collection, cleared drainage channels, and public awareness about not dumping into gutters. This is exactly why WasteCure runs scheduled collection routes and community clean-up drives across the Ashanti Region: every skip of waste removed from a roadside or drain is water that will actually flow the next time it rains.

What you can do

If your street, market or estate has a drain that regularly clogs with rubbish, the fix is rarely more concrete - it is consistent collection. Talk to your assembly about drain clearing schedules, and make sure your own household or business waste goes to a collector rather than a gutter.
