The Nairobi County Government has issued fresh directives after heavy rains on Sunday, May 11, rendered key roads within the capital and its environs impassable.

Nairobi's Chief Officer for Environment, Geoffrey Mosiria, sounded the alarm over what he believes is the key cause of flooding in the city, as he blamed the phenomenon on the construction of structures on the county's drainage systems.

While urging motorists to exercise caution during the rainy season, Mosiria also put city landlords on high alert as he vowed stern action on any structures which were impeding the flow of water in the county drainage systems. "We issued a notice for the removal of structures from the drainage systems.

With the growing population, land is covered by structures, so most of the water goes to the drainage systems," the Chief Officer of Environment observed.
