Residents and businesses in several parts of Nairobi will experience water supply interruptions following the emergency shutdown of the Kabete Distribution Mains.
The interruption, announced by Nairobi City Water & Sewerage Company Ltd, follows the vandalism of a major pipeline supplying water from the Kabete Water Treatment Plant near Kianda School, off Waiyaki Way.

Nairobi Water Production Reduced by 35 Per Cent
The emergency shutdown comes as Nairobi and neighbouring areas face longer water rationing periods following a 35 per cent reduction in water production at the Ngethu and Kigoro treatment plants.
In a notice issued on November 9, Nairobi Water attributed the production reduction to declining water levels at Thika/Ndakaini Dam following below-average rainfall in its catchment area.
“Nairobi Water wishes to inform its valued customers and the general public that due to declining water levels at Thika/Ndakaini Dam, water production at Ngethu and Kigoro Water Treatment Plant has been reduced by 35% with immediate effect,” the company stated.
The cut is expected to affect customers served by Nairobi City Water and Sewerage Company, Githunguri Water and Sanitation Company, Kiambu Water and Sanitation Company, Karuri Water and Sanitation Company, Mavoko Water and Sewerage Company, Oloolaiser Water and Sewerage Company, and Olkejuado Water and Sewerage Company.
Earlier, the company announced a planned 24-hour water supply interruption from November 9 to November 10 to facilitate the installation of new pipe connections near Kianda School, off Waiyaki Way.
Current Tariffs
In a gazette notice dated February 27, Nairobi Water announced that customers are subject to a new tariff structure approved by the Water Services Regulatory Board (WASREB) effective for the 2025/2026 to 2028/2029 financial years.
“Having considered the application, the written and oral submissions by all stakeholders and the current data, WASREB has determined that an upward tariff review is justified for NCWSC to improve service delivery, operate sustainably and protect consumer interests by meeting the tariff conditions attached to the tariffs,” WASREB explained in the approved tariff review.
However, the company clarified that customers with non-functional meters are billed based on the average of their bills for the preceding three months.
