Athi Water Works Overhauls Line Valves at Ngewa and Kiambu Chambers

The Athi Water Works Development Agency has commenced the dismantling of line valves at the Ngewa and Kiambu chambers, marking a critical phase in the technical strengthening of the Northern Collector Tunnel (NCT) Bulk Water System. This infrastructure remains a cornerstone of regional utility management, currently facilitating the delivery of 140 million litres of clean water to consumers every day.

Technicians on-site are focused on the removal of heavy-duty valves within the subterranean chambers to allow for comprehensive reinforcements. These works are designed to ensure the long-term structural integrity and operational efficiency of the transmission network. The NCT system is a vital link for the broader Nairobi Metropolitan Area, and these scheduled interventions are necessary to prevent future system fatigue.

The ongoing activity at Ngewa and Kiambu forms part of a wider maintenance strategy aimed at optimizing the bulk water network. By addressing specific valve configurations now, the agency intends to bolster the resilience of the pipeline against the high pressures required for large-scale distribution.

Athi Water Works continues to oversee the technical progress at both sites, with specialized teams managing the heavy machinery required to navigate the confined chamber spaces. The dismantling process is the first step in a series of upgrades intended to sustain the massive daily output of the system.

The Northern Collector Tunnel project has been a focal point for infrastructure development in Kenya, specifically targeted at resolving long-standing water deficits. Maintaining the system at peak performance is essential for the millions of residents who rely on this specific bulk water source for their daily needs.

While the dismantling of valves requires temporary adjustments to the flow management within the chambers, the agency is prioritizing the completion of these works to maintain the reliability of the 140 million-liter daily supply.
