Mosiria urges residents to help unblock drains as rains cause flooding
By Ascah Mwango, October 3, 2025Nairobi County Environment Chief Officer Geoffrey Mosiria has called on residents to help clear blocked drainage as heavy rains continue to pound the city.
In a statement shared on his X account on Friday, October 3, 2025, Mosiria expressed frustration that despite ongoing efforts by the county to address drainage challenges, some residents continue to dump waste into the drainage channels, worsening the situation.
Mosiria emphasised that effective drainage management requires collective responsibility and urged residents to step in and help where they can, especially by clearing trenches and drainage outside their homes and businesses.
“Mvua kidogo tu na nimeanza kupata strays from all corners. Issue ya drainage tunajaribu kila wakati kusort, but the same people responsible for the blockages wakichukuliwa hatua, wengine wenu mnateta jameni,” Mosiria said.
“Right now, we are on the ground in partnership with other county service teams to unblock zile drainage systems zilizoziba na kusababisha floodings. Lakini pia, if you’re in a position ya ku-unblock mtaro iko mbele ya nyumba yako ama biashara yako, kindly do so. It’s a shared responsibility. Stay safe, drive carefully, and keep warm this rainy season,” he added.
Heavy downpour
Mosiria’s appeal came as the Kenya Meteorological Department warned of intensifying rainfall across the country through the weekend.
In its statement released on October 3, 2025, the department said the ongoing rains affecting many parts of the country were expected to increase in both intensity and spread between Friday and Sunday.
“The ongoing rains over several parts of the country are expected to intensify in amount, spread, and intensity from today through Sunday. Rainfall is likely across parts of the Central Highlands, including Nairobi, the Lake Victoria Basin, the Rift Valley, Western, and North-western regions,” Kenya Met said.
The department forecast that isolated heavy showers would range between 20 millimetres and 50 millimetres within 24 hours, with some areas experiencing rainfall exceeding 50 millimetres.
“Isolated heavy rainfall of 20mm to 50mm in 24 hours, and in some places very heavy rainfall exceeding 50mm in 24 hours, may occur over parts of these regions. These intense rains may lead to localised flooding, slippery roads, and possible disruptions, so stay alert and plan your activities carefully,” the statement added.
Kenya Met cautioned that the heavy rains could disrupt daily activities, particularly in urban centres with limited drainage systems. The agency warned that slippery roads and reduced visibility could affect transport and that communities in low-lying and flood-prone areas faced the risk of temporary flooding.
