Ghana Must Overhaul Drainage Systems As Floods Worsen GhIE Warns

Ghana must urgently rethink its drainage systems. The nation's current infrastructure is failing. Flooding is becoming more common and severe. The Ghana Institution of Engineering (GhIE) issued this warning recently.

GhIE states that rapid city growth and unpredictable weather are overwhelming old drainage designs. These systems were built to move water away quickly. However, they cannot handle the volume and frequency of rain. This affects major cities like Accra most severely.

Ghana's economic stability relies on functioning infrastructure. Recurring floods disrupt businesses and damage property. The cost of repeated flood damage strains public finances. Previous flood events have caused significant economic losses. This situation aligns with trends of increasing climate vulnerability in West Africa.

GhIE presented a policy brief on the matter. It notes that "Flooding in Accra is no longer simply a seasonal occurrence. It is increasingly becoming a structural challenge." The institution highlights fragmented management systems and poor waste disposal as key problems.

The institution advocates for a major shift. GhIE recommends moving away from old, centralised drainage. They propose adopting decentralized, nature-based solutions. This includes techniques like permeable pavements and rain gardens. These methods mimic natural water absorption. GhIE also calls for new national policies on development and rainwater harvesting.

Implementing these changes could greatly reduce flood risks. It could also improve water quality and create green jobs. GhIE believes this reform is essential for Ghana's resilience. The recommendations support global goals for sustainable cities.

Evidence suggests that Ghana's current approach is unsustainable. The nation must adapt its engineering practices. This transition is crucial for protecting its citizens and economy.

GhIE's findings highlight the critical need for infrastructure upgrades. These actions could prevent billions of cedis in future damages. The institution emphasizes the urgency. Policy reform is needed now.
