SINGAPORE - The island nation is fortunate to be sheltered from many natural disasters, but bad weather can always threaten the water supply, Prime Minister Lee Hsien Loong wrote in a Facebook post on Wednesday (Sept 14).

Prime Minister Lee Hsien Loong shared an aerial photograph of Johor's Linggiu Reservoir that he took en route to China a fortnight ago, showing that the reservoir is at only a quarter of its capacity after "several dry years of low rainfall".

He also put up a second photo, a satellite image taken off Google Earth, to show what the reservoir looked like when full.

"The difference is stark, and worrying," PM Lee pointed out.

"Singapore is fortunate to be sheltered from many natural disasters, but our water supply is still at the mercy of the weather," he wrote.

Water imports from Johor make up one source of Singapore's water supply, alongside water from local catchment areas, reclaimed water and desalinated water.

The development of an integrated system with multiple sources has "mitigated" the meteorological threat to the water supply, said PM Lee, "but we must still do all we can to conserve water".

Urging members of the public to "find out more ways to save precious water", PM Lee posted a link to a webpage by national water agency PUB that offers information on how to conserve water.
