Nairobi City Water and Sewerage Company (NCWSC) has announced a 29-hour water supply shutdown set to affect several estates following planned maintenance works on the Karimenu Transmission pipeline.
In a public notice released on Wednesday, November 4, the company stated that the interruption would commence at 3am on Thursday, November 5, and run until 8am on Friday, November 6, 2026.
The shutdown is expected to disrupt water supply in Kasarani, Mwiki, Clay City, Ruai and Njiru, as well as neighbouring areas.

Other affected estates include Roysambu, Zimmerman, Kahawa Barracks and Kenyatta University (KU), alongside their surrounding neighbourhoods.
Nairobi Water also listed Kayole, Komarock, Soweto and Matopeni as areas that will experience the interruption.
"Nairobi City Water & Sewerage Company Ltd wishes to inform its customers of the shutdown of the Karimenu Transmission pipeline by Athi Water Works Development Agency (AWWDA) to facilitate critical tie-in works," the notice read in part.
The company advised residents in the affected neighbourhoods to conserve the water available to them ahead of and during the planned shutdown.
The latest announcement comes amid ongoing maintenance and repair activities targeting major water transmission infrastructure supplying Nairobi.
