The shutdown is needed to repair the Karimenu Transmission pipeline. The company issued the notice on Wednesday, November 4.
The water will be cut from 3 a.m. on Thursday, November 5, until 8 a.m. on Friday, November 6, 2026. Residents in Kasarani, Mwiki, Clay City, Ruai, Njiru and nearby areas will be affected.
So will people in Roysambu, Zimmerman, Kahawa Barracks, and Kenyatta University, along with their neighbouring estates. The notice also lists all of Kayole, Komarock, Soweto and Matopeni.
The pipeline is being shut down by the Athi Water Works Development Agency (AWWDA) so it can complete critical tie-in works.
NCWSC has asked residents to use their water carefully during the shutdown.
This is not the first disruption this season. On October 26, the company announced a three-day shutdown of the NCT-Kigoro-Gigiri-Kabete pipeline.
That shutdown ran from 11:59 p.m. on October 26 to 11:59 p.m. on October 29. Nairobi Water says it is still repairing and maintaining major pipelines that supply the city.
