Vietnam hydro project builder Cavico Corp. has received an US$8.5 million contract to build a portion of the reservoir for the 20-MW Ngan Truoi hydroelectric project on Vietnam’s Song La River.
Cavico said May 11 it received the contract from the Vietnam Ministry of Agriculture and Rural Development for construction on the irrigation reservoir project at Vu Quang in Ha Tinh Province.
The builder is to be responsible for a diversion dam and a flood spillway with a diameter of 7 meters and a length of 287 meters. Cavico expects to start construction by the end of May and complete the project within 20 months.
The Ngan Truoi irrigation dam is being developed by the ministry with a capital investment of about US$167 million. Ngan Truoi initially was approved by the government in 2006. It is considered a critical project by the ministry.
The project is divided into many portions and contracts that are being awarded at different stages. Upon completion, the dam will provide water to 35,000 hectares of farming land in the six provinces north of Ha Tinh. It also is to reduce damage from the Song La River during flooding season and provide a 20-MW hydropower plant.
