Tercan Dam

The scope of construction of dam mainly consists of 2.400.000 m3 filling of various layers, 50.000 m3 concrete which is used for the spillway, power plant building, intake structure and shaft. Also it includes the manufacturing of penstock, valves, gates and trashracks which mean 1.000 tons of manufacturing.


Because of the existence of pervious alluvial around the core of dam, it was difficult to prevent the water seepage to the 24 m deep dam base, in order to place a clay core. It is being very difficult to overcome the seepage of 600 m3/sec water by pumps, as a measure an injection curtain was formed in the alluvium on upstream side. This way the seepage of water was reduced to 250 m3/sec.
