Work to clean up and rehabilitate sections of the Nairobi River is continuing, with drainage, sewerage, and riverbank interventions underway at several locations across the city.
According to Principal Secretary Raymond Omollo on Tuesday, August 18, 2026, the ongoing works include river sewage separation at Globe Roundabout and installation of sections of a 27-kilometre twin trunk sewer at Baba Dogo.
At Lucky Summer, the river is also being widened, dredged, and reinforced along its banks.
At Dandora, sewer trenches are being excavated and wastewater treatment infrastructure expanded, while efforts are also targeting pollution around the Dandora dumpsite.
Riverbank clearing and levelling are also underway at Gikomba, while the Kariobangi wastewater treatment plant is being expanded as part of efforts to improve downstream wastewater management.
Works stretch across the Nairobi River corridor
At Globe Roundabout, drainage works and the separation of river flows from sewage are underway alongside preparations for a proposed public recreation area.
At Baba Dogo, a pedestrian bridge has been completed as sewer installation progresses. In Lucky Summer, gabions are being used to reinforce sections of the riverbanks as dredging and riparian clearance continue.
The activities are part of the Nairobi River Basin Regeneration Programme, which covers several locations along the river corridor.
Thousands of young people living in settlements along the river corridor have also been engaged through the ClimateWorX Mtaani Initiative in activities including waste collection, environmental restoration, and rehabilitation.
Raymond Omollo outlines ongoing activities
“The transformation of Nairobi into a smart, modern and liveable city is deeply intertwined with environmental conservation,” Omollo wrote.
He said the Nairobi River Basin Regeneration Programme was being implemented through interventions targeting the river system and areas along its banks.
“This vision is being realized through the Nairobi River Basin Regeneration Programme, which is restoring the river system into a cleaner, safer and greener public asset while renewing the urban spaces and communities along its banks,” he wrote.
Omollo also said the activities were taking place across the river corridor at different locations.
“The work stretches across the river corridor, with different interventions advancing simultaneously,” he said.
The programme includes sewerage works, drainage rehabilitation, solid waste removal, riparian clearance and wastewater treatment infrastructure across parts of Nairobi.
The State Department is also supporting implementation through National Government Administrative Officers, who are involved in activities connecting the programme with communities along the river corridor.
