Nairobi_Water_Supply_James Keogh
Rehabilitation of Nairobi water supply and sanitation system.

The aim of the project, which began in 2006, was to secure and increase the capacity of Nairobi's water and sanitation systems by rehabilitating the much-needed infrastructure, which has not been maintained for years. Despite a rapidly growing urban population, the volumes released to the capital have steadily decreased to a minimum of 350,000 m3/day in 2009.


The project comprised five components: rehabilitation of Sasumua dam destroyed by floods; rehabilitation of Ngethu and Sasumua treatment plants; rehabilitation of water pipelines and construction of a fourth pipeline to Gigiri and Kabete reservoirs; rehabilitation of sewer systems and Dandora wastewater treatment plant; construction of kiosks and sanitary blocks and extension of water and sanitation networks in informal settlements.


The volume of water produced increased by more than half between 2006 and 2013. Water sales increased by more than 40%; Sasumua Dam has been rehabilitated and secured; More than 50 kiosks and sanitary blocks have been built in the poorest areas of the city (Kibera, Mathare, Soweto, Embakasi ....); The expanding area of Embakasi has water and sanitation network (photo attached); The master plan cleared the way for the new Northern Collector project (ongoing).
