TAIPEI, Taiwan -- The Water Resources Agency (WRA) yesterday said that in three days it will repair the damaged floodway in Tainan to a degree that will allow water to run through it, noting that it has also asked a professional civil engineering association to investigate the cause of the collapse.
The floodway of Tainan's Gangweigo River (港尾溝溪), which cost approximately NT$1 billion to build, had just become operational on July 27. After being operational for over two weeks, the waterway construction collapsed on the morning of Aug. 15.
The Tainan City Government yesterday released a press statement pointing out that the WRA was responsible for contracting out the 3.8-kilometer waterway construction project and carrying out the acceptance testing. Tainan said the damaged parts of the water channel make up five percent of the total construction, noting that the WRA has made a promise to the city that it will make the floodway functional before next typhoon hits the area.
The city government said that when heavy rainfall fell in Greater Tainan on Aug. 12, the waterway had been very effective in releasing dredge water. The Pao An Industrial Zone (保安工業區) and the Chia Nan University of Pharmacy & Science (嘉南藥理大學) were not flooded due to the newly launched waterway, the city government added.
Democratic Progressive Party (DPP) City Councilor Wang Ting-yu (王定宇) stated that the water channel is an example of shoddy work. Commentators have also speculated that those responsible for the water channel's construction jerry-built it, causing the collapse.
WRA Deputy Director-General Wang Ruei-te (王瑞德) yesterday inspected the damaged parts of the channel and said the construction was contracted out to a professional engineering company. The main construction of the waterway contains steel rods and bars, Wang said. He went on to say that his agency's division of ethics will investigate and identify who should be held accountable for the incident.
WRA official Tien Chiao-ling (田巧玲) said her agency has asked a civil engineering association to inspect the waterway construction, noting that the first priority is to identify the cause of the incident. The cause could be due to flawed design, poor construction work or even natural causes, Tien said.
The WRA's Sixth River Management Office said that to partially repair the damaged floodway will cost around NT$25 million, adding that to completely repair it will cost at least NT$100 million. The office said it has started the repair work, adding that it will ensure that the functioning of the waterway resumes before more heavy rainfall hits the area.
