He fully takes over at the helm, at a time the company, which supplies water and sewerage services to Kenya’s capital, faces mounting pressure to improve supply reliability, curb non-revenue water losses and modernise ageing infrastructure. In these roles, he has been key in in driving the Nairobi Water’s digital transformation agenda, including the modernisation of key systems to enhance operational efficiency, revenue collection and customer experience.
Nairobi Water board chairperson, Arnold Karanja said his leadership during the transition period ensured stability in service delivery while advancing strategic reforms across the organization. “Following a comprehensive and transparent recruitment process, the board is pleased to confirm Martin Nang’ole as managing director.
His demonstrated leadership, deep institutional knowledge and success in spearheading digital transformation initiatives make him well-suited to lead the company into its next phase,” said Karanja. The change in leadership which began last year, followed a court ruling in May 2025 that found no legal basis to retain the then MD Nahashon Muguna beyond the mandatory retirement threshold.

I remain committed to building on the progress made, leveraging technology and innovation to improve efficiency, enhance customer service and expand access to reliable water and sewerage services for all residents of Nairobi,” said Nang’ole in accepting the appointment.
As managing director, Nang’ole will focus on key priorities including reducing water leakages, strengthening financial sustainability, accelerating infrastructure development and deepening digital integration across NCWSC’s operations.
