Vietnam firm to build dam for Ta Trach project

Vietnam hydro project builder Cavico Corp. has received a contract to build dams on the Huong River to create Ta Trach Reservoir, potentially an 18-MW hydropower project.

Cavico said the US$3.4 million contract includes a 1,112-meter-long, 56-meter-tall main dam, four sub-dams totaling 660 meters in length, and an overflow dam with six releasing gates.

The company said the reservoir might include an 18-MW hydropower project that would generate an average of 60 million kWh per year.

Construction of the 717-square-kilometer reservoir on the Huong (Perfume) River is to begin in August, with completion by December 2011. The project is in Duong Hoa village, Huong Thuy District, of Thua Thien Hue Province.

Cavico said the work is part of Package 20 of Ta Trach Reservoir, which is the second largest project in central Vietnam. The project is being developed by Hydropower Management No. 5, part of the Ministry of Agriculture and Farming.

The reservoir is to limit flood damage in Hue, supply irrigation water to 35 hectares in the region, help control water flow, and limit the salt level in the river.
