The Sirvan River has always attracted attention due to its suitable discharge and strategic location. The project site is located adjacent to Darian Village, approximately 25 Km northwest of Paveh City and 150 Km from Kermanshah City.
The phase I studies were based on the results of water resources planning and management. In 2008, the design and construction supervision were subsequently assigned to Mahab Ghodss Consulting Engineering Company under a contract covering the phase II & III studies (general supervision & site supervision).
