Nairobi Water has announced a 24-hour water supply interruption in 17 areas.
In a statement, the utility revealed that the disruption follows a leakage detected on the NCT Raw Water Pipeline near Kigoro Treatment Works.
The company cautioned residents of the impending disruption necessitated by emergency repair works on a critical bulk water transmission line.
“We wish to inform customers residing in the listed areas of a temporary water supply interruption caused by leakage on the NCT Raw Water Pipeline near Kigoro Treatment Works,” the statement read.
According to the statement, the interruption is scheduled to begin on Saturday, June 20, 2026, at 6:00 a.m. and end on Sunday, June 21, 2026, at 6:00 a.m.
This will be a full 24-hour shutdown period to allow engineers to carry out repairs and restore system integrity.
According to Nairobi Water, the shutdown has been necessitated by the need to fix a leakage on a key raw water pipeline that feeds treatment and distribution systems serving Nairobi and surrounding regions.
“Our technical teams will work to restore supply as soon as repairs are completed,” the agency added saying that efforts are already underway to ensure the affected section is repaired within the stipulated timeframe.
Among the affected areas include high-density neighbourhoods such as Kibera, Kawangware, and Kangemi, as well as middle-and high-income zones like Kilimani, Lavington, Karen, and Westlands.
Others include, satellite service areas such as Ruai, Kamulu, and Ngong Road corridors, alongside institutional and administrative zones like Upperhill and Madaraka.
Additionally, regional bulk water service providers, including Mavoko Water and Sewerage Company and Oloolaiser Water and Sewerage Company, are also set to experience downstream effects.
The company has now urged residents to take precautionary measures ahead of the interruption, advising households and businesses to prepare accordingly.
