E' circondata dalle acque, ma di acqua da bere non ne ha abbastanza: la città-Stato di Singapore (quasi sei milioni di abitanti) dipende dalla pioggia e dalle importazioni provenienti dalla Malesia. Ora un sistema avanguardistico di filtraggio permette di recuperare le acque nere della fognatura per reimmetterle nella rete idrica o utilizzarle per la produzione di bevande come la birra, invece di disperderle nell'oceano.
Sarà il futuro anche per il resto del pianeta? Loretta Dalpozzo del TG è andata a vedere.
