Thailand's monsoon rains can sweep across Bangkok with a moment's notice, blacking out the sky and sparking floods that fill the street and then disappear just as quickly as they arrived.
Some 4,000mm of rain pours down on Thailand in a year, most of it between June and December, but shoddy management of the nation's water supply is causing shortages as agriculture, households and industry increase their demands, experts warn.
Demand for water could nearly double within 20 years, from 190 million cubic meters a year to 340 million cubic meters, one study at respected Mahidol University indicates.
