Giải pháp chuyển nước lưu vực phục vụ chống thiên tai, hạn hán khu vực thành phố Kon Tum, tỉnh Kon Tum
Abstract
It is necessary to apply the restoring capacity solutions for existing reservoirs and technology solutions for transfering water between reservoirs to increase the storage of water resources in the Central Highlands provinces. Connecting irrigation systems is an essential solution to regulate water resources for economic development and people's life. Including solutions to transfer watersheds to combat drought disasters in Kon Tum city, Kon Tum province. Water transfer from Plei Krong hydropower project with abundant water resources during flood season will connect and be transferred to other basins with terrain conditions to build reservoirs that can contain a lot of water but less abundant of source aquatic resources on site, such as Dak Sa Men Lake and Dak Nang Lake connected to PLei Weh Lake. This solution is implemented by water transfer tunnel and high water column pump technology with pressure pipe to increase water source. After implementation, the maintenance water volume of Dak Sa Men Lake will increase from 1.35 million m3 to 32.2 million m3. Subsequently, Dak Sa Men lake transferred another 3,717 million m3 from the flood water source of PLei Krong hydropower reservoir into Dak Nang lake to combat the annual drought for 1,214.59 ha in Kon Tum city area and supply domestic water. Currently, there are over 160,000 people and it is expected to reach 204,000 by 2025. The total water source connected and stored in the three lakes mentioned above is 50,327 million m3, which will ensure sufficient water for the area of agricultural crops, arranged according to the plan by 2025, including: Winter-spring rice of 1500 ha; crop rice; 900 hectares; corn and vegetables: 5,234 ha; 1,500 hectares of sugarcane; Coffee: 1000 hectares.
