Thousands of Nairobi residents, businesses, and public institutions could soon face water shortages following a notice by the Nairobi City Water and Sewerage Company (NCWSC) regarding unpaid bills.
In a statement released on October 7, 2025, Acting Managing Director Martin Nang’ole announced that a major disconnection exercise will begin on October 15, targeting all customers with outstanding balances regardless of their category or status.
The enforcement drive will affect domestic households, commercial properties, Ministries, Departments and Agencies (MDAs), county governments, and other water service providers.
“No institution or consumer is exempt from the enforcement measures,” Mr. Nang’ole stated in the notice.
According to NCWSC, the decision follows repeated reminders to customers who have defaulted despite several notices issued over recent months. The company said the move is part of a decisive effort to recover overdue arrears and sustain the delivery of reliable water services across Nairobi.
Customers Urged to Clear Outstanding Bills
The utility has urged all consumers to settle their water bills promptly to avoid disconnection. Reconnections, the company noted, will only be processed after full payment has been made.
Acceptable payment channels include the NCWSC M-Pesa Paybill number 444400, the NCWSC customer portal, authorized banks, and designated pay points across the city.
“The Company remains committed to delivering safe, reliable, and sustainable water services. This commitment, however, relies on timely payment and responsible consumption,” the statement read in part.
Consumers seeking clarification or assistance have been advised to contact NCWSC through its toll-free hotline 0800 724 366, or mobile numbers 0724 253 582 and 0703 080 000. Inquiries can also be sent via email to info@nairobiwater.co.ke
With just days remaining before the enforcement begins, thousands of residents and businesses are racing to clear their dues to avoid disruption in supply.
Recent Water Supply Interruptions
The announcement comes barely a week after NCWSC carried out a scheduled water supply interruption to facilitate the interconnection of the Kigoro–Gigiri–Kabete water pipeline at the Gigiri Pumping Station and Reservoir.
The upgrade, which took place between October 3 and 4, temporarily affected water supply in parts of Westlands and Lavington, including estates along Riverside Drive, Gitanga Road, Convent Drive, King’ara Road, Riara Road, and their environs.
NCWSC said the upgrade was necessary to improve water flow and reliability within the city’s network.
As Nairobi continues to grapple with rising demand and limited water resources, the company has urged residents to use water responsibly and ensure timely bill payments to support the sustainability of the city’s supply system.
