Nairobi Launches Simplified Sewer System, Transforming Sanitation in Informal Settlements

The Nairobi City Water and Sewerage Company has officially launched a simplified sewer system in the Mukuru kwa Njenga area, a move that is transforming sanitation and quality of life for thousands of residents.

For decades, residents in this densely populated community faced unsafe and unhygienic sanitation conditions. Today, the new system marks a turning point: it uses shallow, flexible pipes that are easier and cheaper to install, designed to serve communities where traditional deep sewer lines are not feasible.

According to engineers involved in the project, this innovative design reduces installation costs by nearly 90%, making it possible to extend proper sanitation to previously underserved areas. Each connection now costs approximately 20,000 Kenyan shillings compared to nearly 200,000 shillings for conventional systems.

Local residents have already begun to see improvements in hygiene, safety, and even property values. Many report that rental units with sewer access are now in higher demand. Beyond individual households, the new system contributes to cleaner streets, reduced health risks, and improved dignity for families.

Broader Impact on Kenya–Arab Cooperation

The successful implementation of the simplified sewer system demonstrates Kenya’s growing focus on sustainable urban development and innovation — values shared by many Arab economies.

For the business community, this project reflects Kenya’s commitment to improving its infrastructure and creating healthier environments for investment. It also opens up new opportunities for collaboration between Kenyan and Arab companies in areas such as:

• Water management and sustainable infrastructure

• Urban sanitation technologies

• Environmental engineering and smart city design

• Community-driven development and affordable utilities

This initiative reinforces Kenya’s reputation as one of Africa’s leaders in public-private partnerships and innovation-based growth. It also highlights the government’s determination to make cities more livable, equitable, and ready for future investment.
