NAIROBI, Kenya Apr 3 – The Nairobi City Water and Sewerage Company (NCWSC) has announced a scheduled five-day water supply interruption set to affect multiple estates across Nairobi County.
In a notice issued on Friday, April 3, the utility said the disruption will run from 6:00 am on Monday, April 6, 2026, to 6:00 am on Saturday, April 11, 2026.
According to NCWSC, the shutdown is necessary to facilitate the operationalisation of the Northern Collector Tunnel 1 (NCT1) system by the Athi Water Works Development Agency (AWWDA).
“AWWDA will shut down the Northern Collector Tunnel 1 system to operationalise and satisfactorily conclude all contractual works from Kigoro Water Treatment Plant to Gigiri and Kabete reservoirs,” the notice stated.
Areas expected to be affected include Riverside, Parklands, Westlands, Lavington, Kileleshwa, Mamlaka Line, Valley Road, Hurlingham, Kilimani, Kawangware, Dagoretti, Uthiru, Jamhuri, Upper Hill, Kibera, Highrise, Nairobi West, Lang’ata, Karen, South B, South C, Imara Daima and Tassia.
Others are Ngara, Gigiri, UNEP, the US Embassy area, Eastleigh, Buruburu Phases 3 and 4, Gikomba, Pumwani, Shauri Moyo, Mathare North, GSU, Huruma, Ngumba, Thome, Survey, Safari Park, Baba Dogo and the Industrial Area.
In an earlier update on March 16, NCWSC confirmed that the pipeline along Outering Road had been fully restored, allowing supply to resume in affected areas including Buruburu Phases 1 and 2, Kariobangi North and South, Dandora, parts of Mathare and surrounding estates.
The water company has urged residents and businesses in the affected areas to store enough water in advance and use available supplies sparingly during the shutdown.
“We appeal to our customers for indulgence and urge them to use the available water sparingly as we work towards restoring supply. Any inconvenience is highly regretted,” NCWSC said.
The planned interruption comes weeks after the utility completed major repair works on a transmission pipeline damaged by recent floods.
