Due to concerns raised on Murang'a county rivers, on January 2015, Murang’a County residents convinced the County Government to commission an independent study of the Phase One NCT project. The Technical Committee submitted the report in April of 2015. We decided to act after reading and understanding the alarming, harmful consequences of the NCT project. Below are quotations of some of the Findings and Conclusions.
Project will have long term impacts to 336,877 people in Murang’a who use the rivers. Combined normal flow (Q80) in the three rivers is 267,800 cubic meters per day while (northern collector tunnel) NCT average is 259,200 cubic meters per day, implying that the NCT project will divert more than 97% of the river flow during 90% of the year.
NCT abstraction as currently designed will result to 60% or approximately 216 days every year with zero or extremely low flow downstream. This is equivalent to introducing perpetual drought in Murang’a County.
Tunneling may result to changes in the underground drainage and drying of springs and rivers
Project planning has not demonstrated specific and tangible benefits to the people of Murang’a, nor has consultation with Murang’a taken place to determine nature, size and priority areas of benefit interventions.
Although the AWSB plans to construct a 3 meter diameter tunnel in a zone with numerous hills, valleys and streams that supply water to several hundred thousand Murang’a County residents, the committee stated that “drawing evidence from similar projects tunneling may result to changes in the underground drainage and drying of springs and rivers”. Residents are very fearful that the tunneling will puncture underground aquifers and disrupt current flow paths to rivers and springs.
To assist you learn more about the Organization and our mission, we have created a library of documents, reports, and photos of the Northern Collector Tunnel (NCT) project the targeted rivers and other community projects. We encourage all visitors to this website to view or read the documents on the side. We will continue to add documents as they become available.
