In Lagos, a city of over 17 million people, water demands are mainly being met from tapping the groundwater that lies beneath the city. Boreholes provide water directly at people’s homes or business premises. Borehole construction is being paid for by householders and businesses themselves. Water vendors, selling water in jerry cans or trucks are also prolific. Given the limited reach of the piped infrastructure, much of the water vended is likely to also originate from below ground. In fact, exploitation of the large, relatively shallow aquifers that lie below Lagos is one of the main reasons that the city can continue to grow at all.
