Despite public believing and many experts in this regard , the project isn't economically beneficial . The construction cost after the year of 2000 has been increased by eight times . Besides that , the soil of the region is alluvium and construction may not increase the water level up to more than 15m , and it is so called "dead water" that it is not usable.
The constructors say that" their aim is to provide Arsanjan region with water", but this is not possible because there is a 40 meter difference between the dam level and the level of Arsanjan region . Even though they may transfer the water to region at a high cost , but this is not economically judicious.
