Residents and businesses in 17 parts of Nairobi are set to experience a temporary 24-hour water shortage on Saturday, June 20.
“Nairobi Water wishes to inform its customers and the public of a temporary interruption in water supply that will affect several residential, commercial, and institutional areas in Nairobi and surrounding areas,” the company said in a notice issued Friday.
The Nairobi City Water and Sewerage Company said the disruption will affect estates such as Westlands, Lavington, Kilimani, Upper Hill, Karen, Lang’ata, and Madaraka.
Other areas expected to be affected include Ngong Road, Kibera, Uthiru, Kawangware, Kangemi, Ruai, Ngundu, and Kamulu.
Customers served by MAVWASCO and Oloolaiser Water Company, including sections of Ong’ata Rongai, will also face interruptions in supply.
The disruption is linked to a leak on the NCT Raw Water Pipeline near the Kigoro Treatment Works, prompting urgent repairs.
Nairobi Water said the leak needs immediate attention to protect the integrity of the water transmission system and maintain reliable service delivery.
The pipeline is a major part of Nairobi’s bulk water supply network, transporting untreated water from upstream abstraction points to the Kigoro Treatment Works for processing before distribution.
Any interruption along the line directly lowers the amount of water reaching the treatment plant, straining supply in parts of the capital that rely on the system.
Officials say such leaks are especially serious because they cause major water losses before treatment and can undermine system stability if not handled quickly.
“Customers in the affected areas are advised to store enough water for domestic, institutional, and commercial use before the shutdown period,” the company said.
Normal water supply is expected to resume at 6am on Sunday, June 21.
