Selangor Water Dam Full, Overflowing


SHAH ALAM, 24 Dec: Selangor Waters Management Authority (SWMA) today refuted claims by Pandan Member of Parliament, Datuk Seri Ing Tee Keat regarding the alleged supply decline and the absence of raw water resources in Selangor.

SWMA Director, Md Khairi Selamat said that the statement is inaccurate because almost all the dams in Selangor have recorded full water levels.

Md Khairi said that until December 20, 2012, the water capacity for Subang Lake Dam, Semenyih Dam, Langan Dam, Klang Gates Dam and Batu Dam are all 100 percent full.

He said there also have been overflows occurring at Subang Lake Dam, Langat Damn and Semenyih Dam.

“Meanwhile, the water capacity at Sungai Tinggi Dam on the same date is at 93.33 percent.

And for the Sungai Selangor Dam, up till December 20, 2012, the water capacity has risen to 90.17 percent which is 207.40 million cubic meters at a height of 216.65 metres.

“This increase is compared with the water capacity of the dam on October, 11, 2012, which is 52.02 percent with a total amount of 119.65 million cubic metres at a height of 199.3 metres,” he said.

He further explained that the total amount of water flow from rivers is able to supply raw water for five water treatment plants (WTP) in Rasa, Rantau anjang and Bestari Jaya.

Daily balance readings for this flow is high compared to the minimum flow requirement of 300 Million Litres Per Day (MLD).

“Meanwhile, water release from Sungai Selangor Dam has reduced to 91.34 MLD on December 20, 2012.

“This reduction in water release is compared to 521.3 MLH on October 11, 2012. Patterns and the average water levels of the Sungai Selangor Dam from January till November 2012 is shown is Graph 1,” he added.

Sungai Selangor Dam and Sungai Tinggi Dam capacity is expected to increase further due to heavy rainfall during the Northeast Monsoon from November till March.

“Based on the increase rate of the reservoir, the capacity of these two dams is expected to return to full before February 2013,” he added.
