Nairobi Water has announced a temporary water supply interruption that will affect several parts of the city from Monday, June 15, 2026, at 10 pm to Tuesday, June 16, 2026, at midday, following a leakage on a major transmission pipeline.
The utility said the interruption is necessary to facilitate urgent repairs on the NCT-Kigoro-Gigiri-Kabete transmission pipeline at Gatundu, which serves multiple high-demand areas within the capital.
“This is to inform you of a temporary water supply interruption that will affect several residential and commercial areas in the City. The interruption is due to a leakage on the NCT-Kigoro-Gigiri-Kabete transmission pipeline at Gatundu,” the notice stated.
