SHAH ALAM, March 19 — Selangor said today it is likely to extend the ongoing state-wide water rationing drive for one more week as its dams still lacked adequate supply despite the recent bouts of rainfall after a prolonged dry spell.

Mentri Besar Tan Sri Khalid Ibrahim said although the water levels of some dams in the state had reached 65 per cent, the state needed more time to assess the situation.

“We will not be changing our operation plans for one more week… we are still working on studying whether we still need water rationing,” he told reporters at a news conference here.

State executive councillor Elizabeth Wong, who was also present, said water reserves at the Sungai Selangor dam were still at 39.7 per cent despite the rain over the past few days.

“It is not enough, we still need to replenish two months of having no water,” the Bukit Lanjan assemblyman said.

Water levels at two key dams at Klang Gates and Langat also continue to drop despite recent bouts of rain.

Nearly 70 per cent more households in the Klang Valley have been affected by the ongoing water rationing in Selangor which began last month.

The state’s main water supplier, Syarikat Bekalan Air Selangor (Syabas) announced last week an expansion of the areas affected by water rationing.

Parts of six districts that are undergoing the alternating supply schedule, Kuala Lumpur, Petaling, Klang/Shah Alam, Gombak, Kuala Selangor and Hulu Selangor — that had previously escaped the ration — are now on the list.

The alternating schedule of two days of supply and two days without remains unchanged, as do the zone designations previously announced, Syabas said, forcing consumers to rely entirely on stored water during days without supply.

Syabas announced the first stage of the scheduled water distribution plans for three districts in Selangor — Hulu Langat, Kuala Langat and Sepang — in February.

The water rationing for the 60,185 households in the three districts was implemented after the closure of water treatment plants Cheras Batu 11 and Bukit Tampoi.

The two plants were shut down by Syabas on January 28 after the hot spell caused ammonia levels in raw water sources to rise.
