Страна: Kazakhstan
The aim of the project is the completion of the partly constructed Yntymak (Intumak) reservoir at the Nura river in Central Kazakhstan. Construction of the dam was started in the 1980s but spillway and ancillary village protection dams were never completed. The reservoir acted as pollution trap as mercury contaminated sediments settled in the reservoir. A dam safety study revealed unsatisfactory condition of the main dam.
The dam must be rehabilitated, the missing reservoir structures as the spillway and the village protection dams must be constructed in order to gain from an operational water reservoir for the future water supply to Astana and for the Korgalzhyn nature reserve.
