Government Will Test Flood Bangkok’s Canals

The government will begin its controversial testing of Bangkok’s network of canals by releasing large amounts of water in the city’s east and west waterways to check their draining efficiency. The tests will be halted if it rains, officials assured.

The water draining efficiency tests in Bangkok will be held on September 5 and September 7, said Mr. Royaon Jitdon, the chairman of sub committees to follow to analyze and allocate water to look after and administrate and manage all the water of the system, under the Committee of Water Administration and Allocation.

On September 5, test will be held at the west area at Taweewattana canal, with the aim being to increase the drainage efficiency of the canal.

At the western gate, Taweewattana canal would be closed, and water would be drained by pumps in the Bangkok Yai station Mon canal, to release water into Chao Phraya river. The water flow would be maintained by pumps in Kratumban station to release water into Ta Chin river.

The drainage path will be tested through Praya Rajamontree canal, Bang Phai canal, and from Bang Wag canal to the Klong Rajamontree pump station.

At total of 14 water pump impellers will be used in the water flow test. Four locations will have water-flowing measuring machines, and there will be11 automatic water level measuring stations, as well as three locations for automatic rain measuring stations.

An unmanned spacecraft used for space exploration, Athena 1, will be used to transmit photo images of the water flow during the test.

On September 7, the test will be conducted at the east side of Lard Prao canal, to test the efficiency of diverting water into the San Saeb drainage tunnel system using water impellers in the Lard Prao canal.

At the east area, the pumping station would be at San Saeb canal. The pumps would be running at full potential and propel the water pushing system in Bang Khane canal in two directions, to divide water from the Lard Prao canal into the Bang Khane pump station.

A total of 19 equipment pieces will be used in that test, including 4 water-flowing measuring machines, 10 automatic water-level measuring stations, 2 automatic rain measuring stations, and the Athena -1 spacecraft.

For people worried about the canals overflowing, Mr. Royaon said that the test would measure up to 30 percent of canals’ and the river’s potential capacity.

The automatic rain and water measuring systems will also monitor the situation closely, he added. If there is heavy rain while testing, the test will be terminated immediately, or if the water level overflows riverbanks, officials have prepared contingency plans.

Before decided to test the canals, the committee met continuously for two months to determine the safest methods of testing, so Mr. Royaon is confident the public will not be in danger.
