Nairobi Governor Johnson Sakaja has announced plans to expand sewer lines across key states across the Capital  led by the Nairobi City Water and Sewerage Company (NCWSC).

 NCWSC Chairperson Arnold Karanja said the initiative aims to enhance sanitation services and accommodate the city's growing population, which exceeds five million people daily.

During a recent site tour of Makongeni, Eastleigh, and Kawangware, NCWSC Chairperson Arnold Karanja revealed that plans are underway to extend sewer lines within Nairobi’s Central Business District (CBD), including around the Supreme Court area to modernize the city’s sewer system.

He noted that the project will be executed in phases based on necessity.

“One of the major undertakings is the Kawangware Sewer Rehabilitation Works. This project involves installing a 5.8-kilometre sewer line to serve Kabiru and Kawangware wards. Currently 30% complete, the project is expected to be finished by June 2025, significantly improving sanitation services in these densely populated areas.”

Further, he said another project is the proposed sewer upgrade along Eastleigh’s 3rd Avenue, which is expected to be finalized by the end of 2024.

It features a sewer pipeline to enhance the sewer system serving Kaloleni, Makongeni, and parts of the Industrial Area along Lusaka Road.

Additionally, Karanja revealed that the sewer line will cater to the affordable housing projects in Shauri Moyo and Bahati.

In Mowlem Ward, NCWSC is constructing a new sewer line draining into the Nairobi River Trunk Sewer.

The project spans 8 kilometers and includes rehabilitation and the construction of new trunk sewers to serve the entire Mowlem Ward and Umoja III, improving drainage and sanitation across the city.

Moreover, he said NCWSC works on sewer projects in Umoja I, Kayole North, Upper and Lower Savanna, and Embakasi Ward to upgrade Nairobi's sewer infrastructure to address the city's growing population and need for improved sanitation services.

"The completion of these sewer lines will not only improve sanitation but also support the city's broader urban development goals. We are committed to delivering these projects on time to ensure that all residents benefit from improved sanitation services."
