Thousands of boreholes have been sunk in Nairobi. But according to experts, it is unclear what amount of groundwater is available, let alone its quality.

Well-heeled Nairobians are spending about Sh4 million to sink boreholes and install facilities to channel water out. That water is sold through bowsers to affected inhabitants.
