 GEORGE TOWN: A cracked underground drain caused rainwater to flood the earth beneath a road in Tanjung Bungah, causing a retaining wall to burst open and creating a 10m-wide “cavern” beneath the road.

Residents along Lembah Permai woke up last Friday and found part of their street had caved in.

An abandoned house on lower grounds next to the street is teetering on the brink of collapse after water washed away the earth beneath the house’s foundation.

Where the opening of the 40cm-in-diameter underground drain used to be is now a maw around 10m across, with chunks of the wall lying down the slope.

The minor landslide brought back fearful memories for residents because it is less than 1km from the Tanjung Bungah landslide that happened in October 2017, which killed 11 construction workers.

“It was raining so much last week. The water from this drain comes from most of the roadside drains in hillside and it was gushing almost all day and night.

“Luckily, no one lives in that house now. It was abandoned many years ago,” said neighbour Teh Choon Pin.

When the southwest monsoon began on May 6, it was raining almost continuously for five days in Penang and this retaining wall burst open on the fifth day.

Resident Zuhaimi Che Mat, who lives just about 30m from the wall, said it was the first time this has happened in the 50 years she lived there.

R“The water from the drain flows into the stream heading out to sea. When it rains heavily, water from the hills comes gushing down the stream and out of the drain,” she said.

State Works Committee chairman Zairil Khir Johari, who is also Tanjung Bungah assemblyman, said the state approved an emergency fund of RM220,000 and a contractor has been appointed to start repair works.

“The underground drain had cracked and water was seeping into the soil and weakening the road foundation.

“We knew there were problems and the Public Works Department was in the process of calling for a tender before the wall burst open,” he said.

He said the hassle was that there were many utility cables and pipes running under the road that went down too.

“There is an 11kV electricity cable, water pipes, telephone cables and others. So many agencies will be involved in the repairs,” Zairil added.

Penang hit by floods again !

https://youtu.be/ooyXvqmxbvw

GEORGE TOWN: Some 20 houses located on a slope in Hong Seng Estate in Mount Erskine were flooded due to blocked underground drainage.

“Not again!” was the reaction of factory worker S. Kalaiselvi, 42, who found herself neck-deep in water at her house at 2am yesterday after a three-hour downpour.

She waded through the water to higher ground with her parents, who are in their 60s.

“I have been living here for 26 years and only now am I seeing such floods,” said Kalaiselvi, who also had to move out when her house was hit by the massive floods on Nov 4 and 5 last year.

Her father Subramanian Peru­mal, 68, said he was still waiting for the relevant authorities to resolve the problem.

At the site, firemen had to install a water pump to draw out the rainwater, which flooded most of the units to waist level at one point.

It was the third time that the area was flooded since October last year.

Last Oct 30, blocked underground drainage caused floodings affecting six houses during an evening downpour, followed by massive floods during the Nov 4 and 5 storm.

On Sept 29 last year, seven houses in the estate were also affected by soil erosion.

Consultant engineer Datuk Lim Kok Khong had said the soil erosion was due to water seeping under the ground.

Kebun Bunga assemblyman Cheah Kah Peng, who has been barred from helping out with the registration of flood victims for the one-off RM700 aid given by the Penang government, was also there but offered no concrete solution to the floods in the area.

Pulau Tikus assemblyman Yap Soo Huey said nine houses had to be demolished to make way for repair works.

She said they had offered owners of the nine affected houses a low medium-cost unit each as compensation, but the residents insisted on staying put.

Earlier, Penang Flood Mitigation Committee chairman Chow Kon Yeow said the latest floods were caused by the continuous downpour that began on Thursday evening.

“The rain also coincided with a 2.34mm high tide at 2.30am yesterday,” he said.

Chow said the short-term measures to deal with the floods were to dig and deepen the rivers, and carry out upgrading and cleaning works at riverbanks to ensure that there were no blockages.

In Bukit Mertajam, a low wall sealing off the entrance to a lorry driver’s house prevented it from being submerged in floodwaters all over again.

While the water on the road outside was up to knee level, Heng Kai Chin’s home remained relatively dry, thanks to the metre-high barrier of cement and bricks.

But Heng, 43, still skipped work yesterday to keep an eye on the flooding.

A state flood report said water had entered at least 100 homes in Bukit Mertajam.
