IAN NEILSON, CAPE TOWN EXECUTIVE DEPUTY MAYOR

摘要

Nearly everyone working in the water industry remembers in January 2018 when officials in Cape Town, South Africa, set "Day Zero" for April 21—the estimated day when the city's useable water supply would disappear. Could that really happen, people asked? Could a major city really run out of potable water for its residents? City officials convinced its residents the threat was real and that efficiency measures had to be taken by everyone. Since establishing the warning, Cape Town's government and the city's population of more than 4 million residents have taken incredible steps to conserve water.
