Kenya's rapidly growing capital city is facing severe problems with the supply and quality of its water supply, driving people to buy it from unsafe and potentially contaminated sources.

The demand (for water in Nairobi) is higher than supply. We are 20 years behind…so we need to develop new sources.Nahason Muguna

Nahason Muguna, the head of the Nairobi City Water and Sewerage Company (NCWSC), appeared on national television recently and expressed serious concerns about the pace of improvements to the water supply in the face of a rapidly growing population over the past few decades.
In 1990, more than 90% of the population in Kenya's urban areas had access to clean water, according to the United Nations.
