Thinking big

To Bangkok Governor Sukhumbhand Paribatra, purchasing sandbags and water pumps for flood control is a waste of money.

‘‘Over the past three years, Bangkok has spent more than 11 billion baht on those short-term flood prevention measures,” he said yesterday.

“However, Bangkok is still flooded after heavy rain. It’s because those measures are not a long-term answer to the flood problem.’’

Bigger and more permanent solutions are required he said and he announced that City Hall is planning to build four more giant underground tunnels to complete its ambitious and long-term flood prevention plan for Bangkok.

The added tunnels would double the efficiency of the city’s water drainage system, MR Sukhumbhand said .

The new drainage system will be made up of four gigantic tunnels, each with a diameter of five to six metres.

They will be about three times larger than existing drains which are 1.8m in diameter.

The four new tunnels will increase the total length of drainage tunnels in Bangkok to 50km from 14km.

The first tunnel would be completed and enter operation in January, MR Sukhumbhand said.

Construction of the second tunnel is expected to begin during the first half of next year and the third and fourth in 2012.

The project has been supported by the Engineering Institute of Thailand, he said.

Suchatvee Suwansawat, dean of engineering at King Mongkut’s Institute of Technology Ladkrabang, said building underground drainage tunnels was the best way to prevent flooding in major cities.

Drainage tunnel systems had been constructed in several major cities in other countries to prevent flooding, said Mr
Suchatvee, who is a member of the tunnel and underground construction committee of the Engineering Institute of Thailand.

The cost for the construction of underground drainage tunnels is about 150 million baht a kilometre, he said.
