NAIROBI, Kenya — Nairobi City Water and Sewerage Company has confirmed the resumption of water supply to several eastern Nairobi estates after engineers repaired a major transmission pipeline damaged by recent floods along Outer Ring Road.
The utility said the pipeline had been severely damaged by floodwaters, cutting off supply to thousands of homes and forcing residents to rely on emergency deliveries while repair teams worked to restore the network.
“We are pleased to announce that the major transmission pipeline along Outer Ring Road, which was damaged by recent floods, has now been fully repaired and restored,” the company said.
Water services have now resumed in Buruburu Phases 1 and 2, Kariobangi South, Kariobangi North, Dandora, and parts of Mathare after engineers completed critical repairs.
According to the utility, the restoration involved intensive welding and fabrication works on a damaged section of the pipeline near a river crossing, where strong floodwaters had weakened the infrastructure and disrupted transmission to large parts of eastern Nairobi.
Before the repairs were completed, residents were urged to request emergency water deliveries through the company’s service menu by dialling *260# and selecting Option 5.
The disruption extended beyond the Eastlands area, affecting estates including Eastleigh Section Three, Kiambiu, Jerusalem Estate, Uhuru Estate, Jericho Estate, Ofafa, Harambee Estate, Korogocho, Lower Kabete, and Brookside Drive, where households experienced dry taps for several days.
Nairobi has long faced water supply challenges. Daily demand in the capital exceeds 900 million litres while available supply averages about 525 million litres, leaving a persistent deficit that affects millions of residents.
Most of the city’s water is sourced from the Thika Dam, Sasumua Dam, and Ruiru Dam systems before being treated at the Ngethu Water Treatment Plant and distributed through the capital’s pipeline network.
To prevent similar disruptions in the future, the company said engineers are raising sections of the new pipeline above river level to shield the infrastructure from flood damage whenever heavy rains hit the Outer Ring Road corridor.
Even as water supply returns to several estates, repair teams are still working on distribution lines serving Kiambiu and Korogocho. Engineers say full water flow will resume once the remaining sections are repaired.
The restoration comes as Nairobi continues to deal with the aftermath of severe mid-March flooding that has left at least 33 people dead in the city and more than 66 fatalities nationwide, while also destroying homes, sweeping away vehicles, and damaging key infrastructure in low-lying settlements.
On Monday, Johnson Sakaja ordered a 48-hour multi-agency action plan to address the worsening flooding crisis, directing officials to map flood hotspots, assess repair costs, and prioritise urgent interventions across the capital.
