Water in Selangor dams can last for six months with little, no rain

The water level at Klang Gates dam fluctuates due to high usage.

SELANGOR’S seven dams are at optimum level and water supply can last for six months with intermittent rain or no rainfall, says Selangor Water Management Authority (LUAS).

A spokesperson said as of March 4, the water level at Tasik Subang dam was 100%, Semenyih dam (99.34%), Sungai Tinggi dam (98.06%), Sungai Selangor dam (96.89%), Langat dam (90.36%), Batu dam (91.14%) and Klang Gates dam (79.98%).

“The seven main dams deliver water to 34 intakes in water treatment plants (WTP),” said the spokesperson.

The seven dams supply water to consumers in Kuala Lumpur and Putrajaya as well.

Selangor infrastructure and agriculture committee chairman Izham Hashim said the water level at Klang Gates dam fluctuated due to high usage, but there was no cause for alarm.

“It is still raining everywhere, including at water catchment areas, which allows water at the reservoirs to be replenished.

“The situation in the rivers (that supply water to the dams) is satisfactory, with no obvious drop in water levels,” said Izham.

The Klang Gates and Batu dams have dual purpose: storage and flood mitigation.

“Selangor government through LUAS has identified 100 ponds as an alternative water source for use during a drought, under the Water Resources Assurance Scheme (SJAM) project,” said Izham.

They can provide additional raw water supply during the dry season for an extra three months.

This gives the state a total of nine months of water storage.

At the same time, Pengurusan Air Selangor Sdn Bhd has urged residents to use water sparingly.

The average national water consumption is 226 litres per person per day while Selangor folk use 250 litres per person per day.
