Nairobi residents in several estates and neighbourhoods across the city are set to experience a 24-hour water supply interruption beginning Monday, November 9, 2026, following planned maintenance works by the Nairobi City Water and Sewerage Company.
In a public notice, Nairobi Water announced that the interruption would commence at 8:00 a.m. on Monday and end at 8:00 a.m. on Tuesday, November 10, 2026, affecting several residential and commercial areas within Nairobi County.
The company said the planned shutdown is necessary to facilitate the installation of essential new pipe connections near Kianda School, off Waiyaki Way, as part of efforts to improve water supply reliability in the affected areas.
Among the areas expected to be affected are Westlands, Riverside, Parklands and their environs.
Other affected neighbourhoods include Kilimani, Kileleshwa, Lavington, Upper Hill, Lower Hill and Madaraka.
The interruption will also affect several key institutions, including Kenyatta National Hospital, Nairobi Hospital, Forces Memorial Hospital, KEMRI flats, Mbagathi Hospital and the Directorate of Defence (DOD).
Uhuru Park and surrounding areas will also experience the planned interruption.
In the southern part of the city, Nairobi Water listed Dog Unit in Langata, Langata Women's Prison, Kibera and Jamhuri among the areas that will be affected by the shutdown.
Residents and businesses in Amboseli, Hatheru, Chalbi, Kenya High, Woodley and along Ngong Road are also expected to experience the interruption.
The planned works are part of infrastructure improvements aimed at strengthening the reliability of water distribution in the affected neighbourhoods, where the installation of new pipe connections is expected to support service delivery.
Nairobi Water has advised customers in the affected areas to use the water already available sparingly throughout the shutdown period to minimise disruptions to household and commercial activities.
The company has also appealed for patience and understanding as its teams undertake the scheduled works, assuring customers that the interruption is necessary to facilitate improvements to water supply services.
The 24-hour shutdown is expected to affect households, businesses, healthcare facilities and other institutions that depend on the city's water distribution network.
Residents are therefore encouraged to make the necessary arrangements ahead of the scheduled interruption, particularly by ensuring they have adequate water reserves for essential domestic and commercial needs.
Customers seeking further clarification or assistance can contact Nairobi Water via its toll-free customer service line at 0800 724 366.
The company said it regrets the inconvenience caused by the planned interruption and appreciates customers' cooperation as it undertakes the infrastructure works.
