SINGAPORE: Even as water-efficient devices helped Singaporeans cut water use by nearly 4.5% over the last decade, a renewed call to do more has been made amid worries that water levels at Johor's Linggiu Reservoir, the country's main supply, are falling.
Singapore is also pushing ahead to its 2030 target of each person using 140 litres a day, down from the 151 litre-figure of last year.
