Northern Collector Tunnel Project Set to Increase Nairobi’s Water Supply

Mon, 22nd February - Nairobi residents are set to begin reaping benefits from the Northern Water Collector Tunnel that has been under construction in Murang’a County as completion is scheduled for April this year.

The World Bank-funded water project located in Makomboki area of Murang’a County is 91 per cent complete and is expected to be launched before June of this year.

A recent inspection tour of the project by four cabinet secretaries led by Amina Mohammed (Sports) accompanied by Joe Mucheru (ICT), Simon Chelugui (Labour) and Sicily Kariuki (Water) confirmed the progress of the project.

The project which is Kenya’s longest tunnel is designed to harness floodwater from three rivers in Murang’a County in order to increase water volumes at Ndakaini dam by up to 152,000 cubic metres daily.

Ndakaini dam is the main water supply source for Nairobi where water supply issues have been a perennial problem in most city estates. The city currently gets 580,000 cubic meters of water daily against a demand of 750,000 cubic meters per day.

According to Pumps Africa, components of the KSh 21.9 billion project include a water treatment plant installed at a cost of KSh 7.1 billion, a 56Km pipeline to Nairobi constructed at KSh 5 billion, and the tunnel will cost KSh 7.5 billion.

The project which is being implemented by the national government involves the construction of river intake structures at Maragua, Gikie and Irati rivers plus construction of access adits at Gikigie, Irati and Kaanja.

Sports CS Amina Mohammed said the project package will include smaller water projects that will increase water connections to local communities in Murang’a, Gatanga, Ichichi and surrounding areas.
