Nairobi Set for Major Makeover Under Ruto and Sakaja’s Ksh80 Billion Plan

Nairobi Governor Johnson Sakaja has revealed how an additional Ksh 80 billion secured through a cooperation agreement between Nairobi City County and the National Government will be used to accelerate key development projects across the capital.

The funding forms part of a broader initiative aimed at addressing long-standing infrastructure gaps and improving service delivery under the Nairobi Rising development agenda.

Sakaja spoke after chairing the first implementation committee meeting under the cooperation framework between the county government and the national government.

The meeting brought together Principal Secretaries and representatives from several national government ministries, departments and agencies under the newly established Joint Steering Committee (JSC) to coordinate and fast-track priority projects across the city.

Sewerage and Sanitation to Receive the Largest Allocation

At the centre of the cooperation framework is the multi-billion investment package, with the largest portion about KSh 33 billion directed towards sewerage and sanitation infrastructure, a sector considered key to cleaning up Nairobi’s rivers and expanding access to sanitation services.

“The investment will fund the construction of two parallel 27-kilometre trunk sewer lines along the Nairobi River corridor, a new sewer treatment plant capable of processing 60,000 cubic metres of wastewater daily, and expanded last-mile sewer connections to households. An additional KSh 15 billion has been earmarked for long-term sewer expansion across the city. This will also help address drainage challenges and bring visible change,” Sakaja explained.

Roads, Bridges and Drainage Systems

Another KSh 8.7 billion will be invested in roads, bridges and drainage systems aimed at improving mobility and addressing the flooding challenges that have affected several parts of the city during heavy rains.

Part of the allocation includes Ksh 2 billion to fast-track the completion of roads under the Kenya Urban Roads Authority.

Energy and Street Lighting Programme

“Energy and lighting infrastructure will receive Ksh 8.5 billion, including KSh 3.7 billion for the installation of 50,000 new street lights across Nairobi, a move expected to enhance security and extend economic activity at night. The programme also sets aside KSh 1.5 billion for transformers and last-mile electricity connections to reduce the cost of power for low-income households, as well as KSh 3.3 billion for prepaid metering, transformers and lighting in informal settlements,” he added.

Water Supply and Waste Management

In the water sector, KSh 5.1 billion will be invested to address chronic supply shortages in Nairobi. The funding will support upgrades at the Ng’ethu Water Treatment Plant and the development of the Gigiri–Shauri Moyo water evacuation corridor, which will improve water distribution across the city.

Solid waste management will also receive a boost through a KSh 6 billion package, combining KSh 2 billion from the national government and KSh 4 billion from Nairobi County to strengthen waste collection and disposal systems.

The agreement further includes institutional reforms aimed at enhancing security in the capital, including the establishment of a Nairobi Metropolitan Police Unit, expected to be operational within 60 days.

He said that the partnership with the national government is expected to accelerate the implementation of the Nairobi Rising agenda and position the capital for improved service delivery, modern infrastructure and stronger economic growth.
