SHAH ALAM - The water crisis in the Klang Valley could be the worst ever, with just about 80 days of supply left in two major dams - despite the daily rain.
The Sungai Selangor dam and Klang Gates dam - each have roughly just over two months of water supply before they hit the critical stage.
During the country's worst recorded water crisis in 1998, 4.2 million people had to survive on 2,553 million litres per day (MLD), a shortage of 105 MLD.
This time round, 7.1 million people need 4,900 MLD but only 4,367 MLD is available - a shortage of 533 MLD.
The only solution is for the dams to get, by April 30, rain equivalent to the average monthly rainfall for November - one of the wettest months of the year.
Selangor Water Management Authority (Luas) director Md Khairi Selamat said water at the Sungai Selangor dam might last 71 days while water at Klang Gates dam 88 days.
"This is assuming the output remains as it is right now, which is 1,000 MLD for Sungai Selangor and 100 MLD for Klang Gates.
"Also, we need 200mm of rainfall for the Sungai Selangor dam to rise to 55 per cent from its current level of 37.38 per cent. Until we reach that target, water rationing needs to continue," he told a press conference yesterday.
