The project focuses on expanding the water transfer and transport capacity of Nairobi’s “North Thika” drinking water supply system. It aims to enhance services for four million people and provide new access to clean water for 180,000 residents in informal neighborhoods.
Context
Despite having significant surface water resources, Kenya faces chronic water shortages and is classified as a “water-stressed country.” Only 60% of urban areas and 40% of rural areas have piped water access. In Nairobi, informal neighborhoods, which account for 50% of the population but cover only 5% of the city’s area, rely on expensive water vendors for access.
Project Description
The initiative will develop Nairobi’s “Northern Collector” bulk water system by constructing:
- New tunnels and pipelines to transfer raw water from the Irati, Gikigie, and Maragua rivers to the Ndakaini reservoir.
- A 42 km pipeline to transfer raw water to the Kigoro treatment plant.
- A water treatment plant at Kigoro with a capacity of 121,000 m³/day.
- A 17 km pipeline to transport treated water to the Kabete reservoir, west of Nairobi.
Additionally, 10 biocentres will be built in six informal sectors. Funding includes contributions from the World Bank, KfW, and the EU.
Impacts
The project will improve water quality for four million people, offering new access to 180,000 residents in informal neighborhoods. It will especially benefit women and children, who are primarily responsible for water collection in underserved areas.
