The main structure of the headworks, the “Release Sluice Dam” (the section of the dam fitted with water-release gates), under the 73.5 MW Middle Mewa Hydropower Project (PRoR Scheme) located in Taplejung, has been completed.

In a hydropower project, river water is controlled and used for electricity generation. But the same amount of water does not always flow in the river. When floods occur during the rainy season, a lot of silt, including sand, mud and stones, flows down the Himalayan rivers. In such a situation, a release sluice dam is constructed to protect the main structure (headworks) of the project.

A release sluice dam is a part of the dam where special gates are installed. When necessary, these gates are opened to allow excess water and sediment-laden flow to be released downstream in a controlled manner.

Its main purpose is to reduce flood pressure, prevent sediment from accumulating in the intake area, and protect turbines and other equipment from potential damage.

Thus, the release sluice dam is considered a highly important structure for the long-term safety and efficient operation of a hydropower project.

The project has achieved significant achievements in the construction work and has successfully completed the main structure towards the headworks. It has been stated that this progress is the result of continuous hard work, commitment and coordination of the technical and construction teams involved in the project.

The project, which is moving forward with the slogan ‘One Team, One Dream’, is working with the goal of completing the construction work within the stipulated time frame. It is stated that with the completion of the release sluice dam, the remaining structural works of the project will now be carried out with greater intensity.

Upon completion, the Middle Mewa Hydropower Project is expected to make a significant contribution to the country’s energy production capacity by supplying electricity through the national transmission line.
