Water supply will be interrupted for 29 hours across several parts of Nairobi as planned works are carried out on the Karimenu Transmission Pipeline.
The shutdown began at 3:00am on Thursday, November 5, and is expected to continue until 8:00am on Friday, November 6, affecting households, businesses and institutions in the northern and eastern parts of the city.

Water interruption affects several estates
Areas expected to experience the disruption include Kasarani, Mwiki, Clay City, Ruai, Njiru and their surrounding neighbourhoods.
Roysambu, Zimmerman, Kahawa Barracks and Kenyatta University are also among the affected locations.
Residents across Kayole, Komarock, Soweto and Matopeni are expected to remain without normal supply during the shutdown period.
Pipeline works behind shutdown
The interruption is necessary to allow the Athi Water Works Development Agency to carry out critical tie-in works on the Karimenu Transmission Pipeline.
The work involves connecting sections of the transmission system and requires the pipeline to be temporarily taken out of service.
Normal distribution is expected to resume after the works are completed, although some areas may experience delays as pressure gradually returns across the network.
Residents urged to conserve water
Customers in affected neighbourhoods have been advised to use stored water sparingly until normal supply resumes.
Households have been encouraged to prioritize essential uses such as drinking, cooking and sanitation while postponing activities that consume large amounts of water.
The shutdown is likely to particularly affect institutions such as Kenyatta University as well as businesses operating in heavily populated estates.
Nairobi experiences another major interruption
The latest outage comes shortly after another major shutdown affected parts of Nairobi in late October.
That interruption followed emergency works on the NCT-Kigoro-Gigiri-Kabete pipeline and affected areas including Westlands, Kileleshwa, Kilimani, Lavington, Karen and Upper Hill.
The repeated shutdowns highlight the importance of maintenance and upgrade works on the transmission systems supplying the capital.
Residents in the affected areas have been advised to monitor updates as technicians work to restore normal supply by Friday morning.
