Nairobi Water urged customers in the listed estates to use available water sparingly during the interruption period and to store sufficient supplies in advance.

“We appeal to all affected customers to use the available water sparingly during this interruption period and to store sufficient quantities where possible. Any inconvenience is highly regretted,” the notice added.

In a notice issued on Friday, February 6, NCWSC gave defaulters a five-day ultimatum to clear any outstanding arrears or risk their water connection being disconnected.

“This exercise, which begins on 11th February 2026, targets all categories of customers to safeguard the financial health and long-term sustainability of water and sewerage services across the City,” noted NCWSC.
