Nairobi County has intensified efforts to prevent flooding in anticipation of the upcoming El Niño rains forecasted for October and November. Teams from the county's Green Army and environmental units are actively clearing blocked drainage systems, sewers, alleyways, and river channels to ensure smooth stormwater flow.
Governor Johnson Sakaja emphasized the proactive approach during an interview on Inooro FM, stating, "We are preparing Nairobi before the rains come. Our teams are on the ground clearing blocked waterways, opening up drainage systems and ensuring that our rivers have the capacity to carry stormwater."
Immediate and Long-Term Flood Mitigation
- The clearing of drainage and waterways aims to address current obstructions that contribute to waterlogging during heavy rains.
- Under the Nairobi River Regeneration Programme, the county is widening sections of the river to boost its capacity to handle increased stormwater volumes.
These interventions come after the Interior Ministry flagged Nairobi among 18 counties at high risk of flooding due to urban drainage challenges and infrastructure strain. The Kenya Meteorological Service has predicted above-average rainfall during the upcoming season, raising concerns over possible floods, disease outbreaks, and infrastructure damage.
Regional Flood Risks
Besides Nairobi, coastal counties such as Tana River, Kilifi, Lamu, Mombasa, and Kwale face threats from flooding, storm surges, and coastal erosion, potentially leading to displacement and food insecurity.
As Nairobi steps up both immediate and infrastructural flood control measures, the effectiveness of these efforts will become clear once the rains commence, especially in historically flood-prone zones.
