PBAPP to draw water from EMD if Sg Muda water level continues to drop

GEORGE TOWN: Perbadanan Bekalan Air Pulau Pinang (PBAPP) will drawdown the strategic drought reserve of the Expanded Mengkuang Dam (EMD) if it cannot abstract sufficient raw water from Sungai Muda.

Its chief executive officer K. Pathmanathan said a maximum of 600 million litres of raw water per day (MLD) would be drawn from the EMD if Sungai Muda continues to shrink due to dry and hot weather.

“As of Tuesday, the water level of Sungai Muda at the intake of the Lahar Tiang PBAPP in Seberang Perai dropped to 1.72m which is below the safe level of 2m, and yesterday (April 17) the water level of Sungai Muda dropped to 1.61m at Lahar Tiang.

“PBAPP continues to abstract sufficient raw water from the river without using EMD, however, PBAPP also successfully conducted a drawdown trial run from EMD in preparation for a worst-case scenario,” he said in a statement yesterday.

Currently, PBAPP abstracts about 1,200 MLD from Sungai Muda for optimal production of treated water at the Sungai Dua Water Treatment Plant (LRA) and the LRA produces 85 per cent of the treated water distributed in Penang daily, he said.

Pathmanathan said the maximum discharge capacity from the EMD is 600 MLD or about 50 per cent of the raw water required by the Sungai Dua LRA to operate optimally.

He said as long as PBAPP can abstract 600 MLD of raw water from Sungai Muda and release 600 MLD from EMD it will not cause unscheduled water supply disruptions in the state.
