KENYAS BIGGEST WATER PROJECT: THE NORTHERN WATER COLLECTOR TUNNEL PROJECT

In line with Vision 2030, the Government of Kenya plans to improve water services in Nairobi City, Kiambu and Muranga Counties. One of the key ways of improving water services is through the construction of the Northern Collector Tunnel Phase 1(NCT 1) scheme. This will entail the construction of 11.8km raw water transfer tunnel along the Eastern fringes of the Aberdare Conservation Area (60Km North of Nairobi), to divert defined flows from Maragua, Gikigie and Irati rivers into existing Thika dam (Ndakaini Dam), treatment of water at Kigoro water treatment plant and subsequent transmission through 1200mm diameter pipeline to Kabete water reservoirs via Gigiri to supply the upper zones of Nairobi. The project will improve water supply to Nairobi City by 140,000 cubic meters per day.
