Instead of a regular faucet that switches on and off, picture a large metal meter box with a slot for a plastic card and a water tap below. The device requires consumers to pay for water before consumption by purchasing a prepaid card. Consumers can then draw water from the meter by inserting the prepaid card into the meter and collecting the water in a portable container. As service is delivered, the balance is adjusted, and the remaining credit displayed. Service is automatically terminated if the payment balance is depleted until the consumer can pay again. The service is most prevalent in South African municipalities. Prepayment meters can also be found in Namibia, Swaziland,Tanzania, Brazil, Nigeria, Curacao and probably other countries, as well. The devices were previously used in the United Kingdom (U.K.) until they were declared illegal in 1998 for public health reasons. As water becomes an increasingly scarce resource, global corporations, many governments, and international financial institutions such as the World Bank, argue that water should be allocated through market mechanisms. But in many developing countries the lack of access to clean and affordable water contributes to the spread of water-borne diseases. More than 2 million people, mostly children, die each year from water borne diseases.
