LATAR BELAKANG: INSIDEN SUNGAI MUDA 29.9.2023

• Pada 22.9.2023, banjir kilat dilaporkan berlaku di Baling, Kedah. Banjir itu menghanyutkan serpihandan tanah ke Sungai Muda, di hulu muka saukLahar Tiang Pulau Pinang.

• Sejak 22.9.2023, PBAPP telah memantau dengan rapikualiti air mentah Sungai Muda. Sehingga semalam(28.9.2023), kualiti air mentah di muka sauk Lahar Tiang di Pulau Pinang adalah mencukupi untukPBAPP mengabstrak bagi pengeluaran air terawat“normal” di LRA Sungai Dua.

​​

• PBAPP perlu mengabstrak kira-kira 1,100 JLH (jutaliter sehari) air mentah dari Lahar Tiang untukmenyokong purata pengeluaran kira-kira 1,000 JLH air terawat di LRA Sungai Dua.

• Mulai 28.9.2023, PBAPP telah melepaskan kira-kira300 JLH daripada Empangan MengkuangDiperbesarkan (EMD) sebagai langkah kawalanawal.

• Pagi ini (29.9.2023), kekeruhan air mentah Sungai Muda di Lahar Tiang melonjak sebanyak 556%, daripada 236 NTU (nephelometric turbidity units) pada 12.00 tengah malam kepada 1,549 NTU pada 7.00 pagi. Dalam mengutamakankeselamatan awam, PBAPP mengurangkanabstraksi air mentah sebanyak kira-kira 70% pada9.00 pagi hari ini.

• Pengurangan 70% dalam pengabstrakan air mentahdi Lahar Tiang ini memaksa PBAPP mengurangkan pengeluaran air terawat di LRA Sungai Dua kepada 715.8 JLH (disokong olehpengeluaran 300 JLH EMD) pada pukul 9.00 pagi.

• Akibat pengurangan pengeluaran air terawat di LRA Sungai Dua pagi tadi, bekalan air kepadapengguna air di kawasan berikut terjejas:

Seberang Perai

Bahagian pulau, Pulau Pinang

1.

Seberang Perai Selatan

3.

George Town

2.

Seberang Perai Tengah (kawasan selatan Rumah Pam Bukit Minyak)

4.

Selatan Bukit Dumbar ke BalikPulau (termasuk Pulau Betong, Bukit Penara, Pondok Upeh danBandar Balik Pulau)

FAKTOR UTAMA YANG PERLU DIPERTIMBANGKAN

 

Sila pertimbangkan faktor-faktor berikut:

 

1.​Ini adalah “gangguan bekalan air tidakberjadual” yang disebabkan oleh kejadian luarandan faktor di luar kawalan PBAPP dan KerajaanNegeri Pulau Pinang.

2.​Kejadian ini berpunca daripada kejadian banjirkilat di Baling, Kedah baru-baru ini.

3.​Pasukan pelan respons kecemasan (ERP) PBAPP membuat keputusan untuk mengurangkanpengeluaran air terawat di LRA Sungai Dua keranakekeruhan air mentah dari Sungai Muda adalah luarbiasa tinggi.

4.​PBAPP terpaksa mengutamakan keselamatanawam kerana LRA Sungai Dua tidak direka bentukuntuk memproses air mentah dengan kadarkekeruhan melebihi 1,000 NTU dengan selamat,untuk menghasilkan air terawat yang selamat untukkegunaan awam.

5.​Pemantauan 24/7 PBAPP terhadap kualiti air mentah di Lahar Tiang (sejak 22.9.2023) dantindakan kawalan awal untuk melepaskan air mentah dari Empangan MengkuangDiperbesarkan (sejak 28.9.2023) telah membantumengurangkan impak kejadian ini.

6.​Sejak 1.00 pagi hari ini, PBAPP telahmenyiarkan amaran waspada mengenaikekeruhan air mentah Sungai Muda di lamanFBnya dan menggesa pengguna air Pulau Pinang menyimpan air mencukupi untuk kegunaankecemasan, berikutan berita mengenai banjir kilatBaling baru-baru ini.

Media Release

YAB TUAN CHOW KON YEOW

Chief Minister of Penang and

Chairman of PBAPP and PBA Holdings Bhd.


PENANG WATER SUPPLY RECOVERY STATUS: 84.1% AT 3.30PM

• Sungai Muda raw water turbidity is improving(547.9 NTU).
• Sungai Dua Water Treatment Plant production capacity 94.6%.  
• Water supply services to 391,239 of 465,004 affected water consumers in Seberang Peraiand Penang Island have been normalised.

PENANG, Friday, 29.9.2023: Perbadanan Bekalan Air Pulau Pinang Sdn Bhd (PBAPP) has “normalised” water supply services for the majority of Penang water consumers affected by the Sungai Muda incident that occurred this morning.

As at 3.30pm today:

• Water supply to 391,239 of 465,004 (84.1%) of affected water consumers in Seberang Peraiand Penang Island have been normalised.

• The turbidity of the raw water from Sungai Muda at the Lahar Tiang Intake has dropped to 547.9NTU (nephelometric turbidity units). PBAPP is abstracting raw water at 100% capacity at Lahar Tiang for pumping to the Sungai Dua Water Treatment Plant (WTP).

• Treated water production at the Sungai Dua WTPhas reached 94.6% of maximum capacity.

PBAPP’s emergency response team (ERP) Team, headed by CEO Ir. K. Pathmanathan, is targeting tocompletely normalise water supply services throughout the state by tomorrow (30.9.2023).

The first priority is to recover 100% treated water capacity at the Sungai Dua WTP. After that, PBAPP needs to optimise pumping treated water into empty pipelines and PBAPP personnel will have to address issues such as re-starting pumps in all affected pump houses and addressing “air-locks”, potential burst pipes, as well as other pipeline issues.

To read the latest updates on recovery works and the water supply normalisation process, please visit the PBAPP FB page.

BACKGROUND: 29.9.2023 SUNGAI MUDA INCIDENT

• On 22.9.2023, flash floods were reported in Baling, Kedah. The floods would have washed down debris and soil into Sungai Muda, upstream of Penang’s Lahar Tiang Intake.

• Since 22.9.2023, PBAPP has been carefully monitoring the Sungai Muda raw water quality. Until yesterday (28.9.2023), the raw water quality at the Lahar Tiang Intake in Penang was adequate for PBAPP to abstract for “normal” treated water production at the Sungai Dua WTP.

​​

• PBAPP needs to abstract about 1,100 MLD (million litres per day) of raw water from Lahar Tiang to support an average production of about 1,000 MLD of treated water at the Sungai Dua WTP.

• From 28.9.2023, PBAPP drew down about 300 MLD from the Expanded Mengkuang Dam (EMD) as a pre–emptive measure.

• This morning (29.9.2023), the turbidity of Sungai Muda raw water at Lahar Tiang spiked by 556%, from 236 NTU (nephelometric turbidity units) at 12.00am to 1,549 NTU at 7.00am. In prioritisingpublic safety, PBAPP reduced raw water abstraction by about 70% at 9.00am today.

• This 70% reduction in raw water abstraction at Lahar Tiang compelled PBAPP to reduce treated water production at the Sungai Dua WTP to 715.8 MLD (supported by the 300 MLD EMD drawdown) at 9.00am.

• As a result of lowered treated water production at the Sungai Dua WTP this morning, water supply to water consumers in the following areas wasaffected:

Seberang Perai

Penang Island

1.

Seberang PeraiSelatan

3.

George Town

2.

Seberang PeraiTengah (areas south of the Bukit MinyakPump House)

4.

South Bukit Dumbar to Balik Pulau(including PulauBetong, Bukit Penara, PondokUpeh and Bandar Balik Pulau)

KEY FACTORS TO CONSIDER

 

Kindly consider the following factors:

 

1.​This is an “unscheduled water supply interruption” caused by an external mishap and factors that are beyond the control of PBAPP and the Penang State Government.

2.​This incident originated from the recent flash floods in Baling, Kedah.

3.​PBAPP’s emergency response plan (ERP) team made the decision to reduce treated water production at the Sungai Dua WTP because the turbidity of raw water from Sungai Muda was abnormally high.

4.​PBAPP had to prioritise public safety because the Sungai Dua WTP is not designed to safely process raw water with a turbidity rating above 1,000 NTU to produce safe treated water for public consumption.

5.​PBAPP’s 24/7 monitoring of the raw water quality at Lahar Tiang (since 22.9.2023) and pre-emptive action to draw down raw water from the Expanded Mengkuang Dam (since 28.9.2023)have helped to lessen the impact of this incident.

6.​Since 1.00am today, PBAPP has been posting alert warnings on the turbidity of Sungai Muda raw water on its FB page and urging Penang water consumers to store some water for emergency use, following news of the recent Baling flash floods.

Thank You.
