The 8.4-kilometre bulk transmission pipeline will deliver an additional 211 million litres of water per day to eastern Nairobi once completed, benefiting an estimated three million residents. The project has received a Special User License from the Kenya Forest Service (KFS) to undertake a section of the works within Karura Forest.
AWWDA Chief Executive Officer Eng. Joseph Kamau emphasized the project's importance in strengthening Nairobi's long-term water resilience. "This transmission upgrade is a strategic intervention to strengthen bulk water conveyance and ensure reliable supply to eastern Nairobi as demand continues to grow," he said.
The project involves installing a DN1400 transmission pipeline from Gigiri Reservoir to Karura Reservoir, before extending to Outer Ring Road. A three-kilometre section between Gigiri and Karura will be installed underground within an existing cycle track corridor inside Karura Forest.
This project is part of AWWDA's efforts to improve Nairobi's water supply system, including the Northern Collector Tunnel, which will provide an additional 140 million litres of water daily, and the Western Nairobi Water and Sewerage Project, a KSh 3 billion initiative targeting over 300,000 residents.
