The government has begun work on the second phase of the Nairobi Sewerage Improvement Programme.

The project which is funded by the African Development Bank and the French Development Agency is part of the Nairobi Rivers Rehabilitation and Restoration Program which aims at the restoration of Nairobi Rivers Basin.

It seeks to increase access, quality, availability, and sustainability of wastewater services within Nairobi and its surroundings including downstream locations. Phase one of the project increased urban sanitation coverage in the region from about 40% in 2012 to approximately 48% in 2017.

The second phase of the project involves the rehabilitation and construction of wastewater treatment facilities at Dandora and the construction of 220km of sewer reticulation network including faecal sludge management infrastructure. In addition, it will see the construction of 50 new ablution blocks and the rehabilitation of 50 already existing ablution blocks within Nairobi informal settlements.

The project is expected to further improve the provision of reliable, safe, and sustainable urban sanitation services in Nairobi, and will improve the economic environment.
