T his December 2025, the torrential rains expose the structural fragility of Greater Libreville: non-existent or obsolete drainage systems, districts built on flood-prone areas, and a lack of drain maintenance. Impassable roads, houses invaded by water, material losses, and health risks fuel the residents' anger. The authorities of the 5th Republic, along with the Mayors and municipal technical services, are now compelled to initiate a profound overhaul of urban planning, including the reconstruction of entire districts.

A Rainy Season that Paralyzes the Capital : Since the beginning of December 2025, intense rains have regularly turned several areas of Greater Libreville into temporary lakes. Nzeng-Ayong, Mindoubé, Ondogo, Akébé, PK12, and the outskirts of Oloumi experience rapid water surges, sometimes in less than an hour. The absence of drainage in some sectors, combined with the obsolescence of a network sometimes dating back over 40 years, prevents any effective evacuation. Roads crack, vehicles are stranded, and economic activities slow down with the pace of the bad weather. In some districts, residents live with their feet in the water, improvising walkways and raising their doorsteps to limit the damage.

The Consequences of an Abandoned Hydraulic System : Repeated flooding causes considerable material losses: destroyed furniture, weakened walls, overflowing septic tanks, landslides, and chronic unsanitary conditions. Stagnant water also promotes waterborne diseases—malaria, skin infections, diarrhea—creating concerning health situations. In parallel, drains clogged by uncollected waste worsen the network saturation. The lack of urban planning has led to the construction of housing in swampy or low-lying areas, where water naturally accumulates. With every rain, residents relive the same nightmare: power outages, cut roads, inaccessible businesses, and sometimes forced evacuations.

The 5th Republic and the Mayoralties Face the Necessary Reconstruction : Faced with this situation, which has become structural, the authorities of the 5th Republic are expected to take a series of profound actions. First, an emergency hydraulic plan must be launched, including the rehabilitation of existing drainage, the construction of new drains in the most exposed areas, and the establishment of a permanent municipal dredging system. Mayors must be given increased powers and resources to supervise the maintenance of the rainwater network, map the risk zones, and mobilize neighborhood chiefs for regular community cleanup campaigns. Above all, some districts built in flood-prone areas—notably recent developments at PK10, Mindoubé, or in the valleys of the Estuaire—must be subject to planned reconstruction, with the progressive relocation of residents and the development of retention basins. To restore confidence, the response must be comprehensive: infrastructure renovation, urban discipline, effective control of building permits, and the integration of municipalities into a more rigorous governance of the capital.
