THE flooding problem in inner George Town will be reduced drastically after the RM6.7mil flood mitigation project in the S10 catchment area is completed by August, 2018.
Penang Island City Council Engineering Department director Addnan Mohd Razali (pic)said the upgrading work would begin in May.
He said the size of S10 catchment area would be expanded to 7.2m from the current 4m.
“The project also include the construction of twin box culvert and a box culvert that will run parallel with Jalan Dr Lim Chwee Leong.
“The other important components of this project are the two sump units in Jalan Dr Lim Chwee Leong and three transition structure units,” he told a press conference at Komtar on Monday.
Addnan said consultants had been appointed to carry out a study and plan the designs to solve flooding problems at the hotspots.
The S10 catchment area covers 112.8ha that encompasses 12 flood-prone areas in Pintal Tali Road, Cintra Street, Kimberley Street, Chulia Street, Muntri Street, Love Lane, Carnarvon Street, Prangin Lane, Victoria Street, Phee Choon Road, Transfer Road and Dickens Street.
The city drainage system is located around the Komtar area, where all the floodwaters received in this catchment would be discharged to the sea through the main drain of the Prangin canal.
State Local Government, Transport Management and Flood Mitigation Committee chairman Chow Kon Yeow said the S10 catchment area was built over 20 years ago to help reduce the floods in the inner city, but the drain was unable to cope with the huge amount of water during a downpour.
“The catchment capacity is designed for 50 years of average recurrence interval,” he said, adding that he hoped the culvert built beside the Prangin canal would also help to eliminate the flooding problem.
State Drainage and Irrigation Department director Sabri Abdul Mulok, who was also present, said a total of 47 flashflood hotspots had been identified with 11 of them to be given priority for the flood mitigation project.
“Mitigation work for the other 36 hotspots will be done in stages,” he said.
