HA NOI -- Bui Trung Dung, deputy chairman of the national department of construction appraisal under the Ministry of Construction, concluded that Tranh River Hydropower Plant "has mistakes in design, construction, supervision and operation".

Dung concluded when leading his department, along with the delegation from Quang Nam Province, yesterday to tour the plant where workers were attempting to mend the dam's leaks.

Dung posited that low-grade concrete was a mistake in dam construction. He added "though there is a simple solution for the leaks, the investor and constructor did not treat the problem on time, which raises great concerns."

According to the delegation, water continued to leak from the expansion joints though they couldn't find any crack.

"There is no pipe for water to be released downstream, which is why the water has leaked," said Dung after checking the dam operation for three hours.

Dung also said the discharge of 30 litres per second was high and needed to be reduced.

The Electricity of Vietnam suggested that the plant's investor should use up water in the reservoir so that the water level could be lower to treat the leaks. Dung said the construction team must immediately check the dam coverage and treat the leakage with concrete, tar or cement, as opposed to the sand they were currently using.

Chairman of the Bac Tra My District People's Committee, Dang Phong said the local people were not satisfied with the current treatment with sand. Phong said the construction crew, and the investor, Managing Board of Hydropower Plant No 3, should make people's lives a "priority" to promote security. Phong even asked to stop the plant operation for safety reasons.

Nguyen Minh Tuan, office head of the Quang Nam Storm and Flood Prevention said there was no purposed plan of escape in the event of a disaster.

He could not imagine how much damage the people downstream of Tranh River and the nearby river of Thu Bon would experience if anything went wrong.

At the provincial level, Nguyen Duc Hai, Party Secretary of Quang Nam Province said the delegation's conclusion had ensured the safety of local authorities and people. However, he said the construction team and investor must learn lessons from their mistakes and fix the problem as soon as possible.

Also yesterday, Deputy Prime Minister Hoang Trung Hai urged the Ministry of Industry and Trade, the Electricity of Viet Nam and the national appraising council to solve the problem in Tranh River Plant to report to the Government. – VNS
