About the Northern Collector Tunnel
The Northern Collector Tunnel (NCT) is a key infrastructure project under Nairobi’s master plan to secure new water sources for the city and its 13 satellite towns through 2035.
Before the project, Nairobi faced an estimated water deficit of 125,000 cubic metres per day.
Funded by the World Bank, the project features Kenya’s longest tunnel, designed to channel floodwater from three rivers in Murang’a County—Maragua, Gikigie, and Irati—into the existing water supply network at Ndakaini Dam, Nairobi’s main water source.
