Sewage pipes checked at site

Sewage pipes checked at site

The Bangkok Metropolitan Administration (BMA) yesterday dispatched a robot equipped with lights and a CCTV camera to inspect the sewage pipeline under the Thai-Belgian Friendship Overpass on Bangkok's Rama IV Road, after a five-metre-wide sinkhole occurr

It is believed that the sinkhole was caused by prolonged seepage through a drainage pipe.

Since initial inspection found no leaks in the sewage pipeline, officials will be scanning the Rama IV tunnel today using the same method. 
 
Adisak Kantee, deputy director of the BMA drainage department, led 50 officials yesterday morning to inspect the sewage pipes for damages, hence blocking traffic from the overpass to the inbound Wireless intersection. Adisak explained that Chong Nonsi district’s 80-centimetre-wide sewage pipeline was located six metres under the sinkhole. Officials pumped out the water and mud until the pipe only had 15cm of water and lifted the manhole cover under the overpass and another at Wireless intersection before dropping a remote-controlled robot to take photos from inside. It took the robot an hour to survey the 105-metre stretch. 
 
Adisak said the robot had found no leaks in the pipe and that the Rama IV tunnel would be inspected today. He said he was sure that the tunnel was fine despite its age, because it is underground and hence could not be affected. He added that the Metropolitan Waterworks Authority pipe would also be inspected soon.
