Heavy rains and flooding have damaged key water distribution pipelines across Nairobi, forcing Nairobi City Water and Sewerage Company to begin emergency repairs as supply interruptions hit multiple residential areas.
Water supply to several Nairobi neighbourhoods has been disrupted after heavy rains damaged critical water distribution pipelines across the city, according to Nairobi City Water and Sewerage Company (NCWSC).
The utility said flooding triggered by the recent downpour washed away sections of infrastructure at multiple river crossings, affecting pipelines serving both eastern and western parts of the capital.
The damage comes as Nairobi continues to experience widespread flooding following overnight rains that also disrupted electricity and transport infrastructure across parts of the city.
Key Pipelines Affected
Among the most significant infrastructure failures was the Outer Ring Road pipeline at the Nairobi River crossing, where floodwaters damaged sections of the distribution network.
The outage has disrupted supply to Buruburu Phases 1 and 2, Kariobangi South and North, Dandora Phase 1, and parts of Mathare.
Another affected line runs between Eastleigh and Kiambiu, cutting supply to Eastleigh Section 3, Kiambiu, Jerusalem, Uhuru Estate, Jericho, Ofafa, and Harambee estates.
A third pipeline linking Korogocho and Dandora has also been damaged, affecting Korogocho, parts of Dandora Phase 1 and Kariobangi North.
In western Nairobi, flooding damaged the Brookeside Drive distribution line between Lower Kabete and Matundu Close junction, disrupting supply to residents along Lower Kabete Lane, Lower Kabete Road and Brookeside Drive.
Emergency Repair Operations
The utility said technical teams have been deployed to affected sites to assess the extent of damage and begin repairs.
The response includes the deployment of specialised equipment such as flushing units, cranes and mobile workshops to restore the pipelines and stabilise damaged infrastructure.
Patrol teams have also been dispatched to monitor vulnerable river crossings and other flood-prone sections of the water network in an effort to prevent further damage.
“We urge our customers to remain patient as we work around the clock to restore water supply,” the acting managing director said in a statement.
“Our teams are committed to resolving these disruptions as swiftly as possible.”
Pressure on Urban Infrastructure
The damage highlights the vulnerability of Nairobi’s aging water infrastructure to extreme weather events.
Much of the city’s pipeline network runs through river crossings and low-lying areas that are susceptible to erosion during heavy rains. Floodwaters can expose pipes, wash away protective soil cover, or damage structural supports.
When such failures occur, repairs often require excavation, pipe replacement and pressure testing before supply can be safely restored.
Impact on Residents and Businesses
Water supply disruptions affect households as well as businesses such as restaurants, laundries, hospitals and small manufacturing operations that rely on consistent access to water.
In densely populated neighbourhoods like Eastleigh, Kariobangi and Dandora, outages can quickly affect thousands of residents and informal businesses.
Utility officials did not provide a specific restoration timeline, noting that repair schedules depend on the extent of structural damage and accessibility to flooded sites.
Customer Advisory
Customers experiencing water-related problems have been encouraged to report incidents through the company’s toll-free customer support line.
The utility said it will continue monitoring the situation and provide updates as repair work progresses.
