Extending the Nairobi Potable Water System (Northern Collector)

Phase 1 of the master plan consists of the construction of: a raw water collection structure at the northern rivers Maragua, Gikigie and Irati (the northern collector), a pipeline from the existing Thika dam to the future treatment plant, a new treatment plant in Kigoro, a pipeline for treated water to the existing Kabete reservoir located on the heights of the city to the northwest. In addition to the production works, this project will also aim to extend the distribution network, particularly to developing neighbourhoods and poor neighbourhoods. A technical assistance component is also planned to assist Nairobi Water, in particular on pricing and unbilled water aspects.
