Project Outline
Poldasht Irrigation and Drainage Network is located in West Azerbaijan Province, 25 km from the city of Poldasht. The area’s irrigation system was based on traditional methods such as border ditch irrigation which resulted in a lot of surface run off. The main objective of the project was, therefore, to provide a modern irrigation and drainage system for 12,000 hectares of agricultural land. The entire project was divided into five sections. The contract for the first section which encompassed an area of nearly 3700 hectares was awarded to Kayson. In addition to the diversion dam, Kayson’s scope of work called for the construction of 16 primary and secondary irrigation and drainage canals, plus the related auxiliary structures, in a triangular area each of whose side spanned nearly 20 kilometers.

The Main Objectives of the Project Were as Follows:

  • Disposal of wastewater and drainage of farmlands
  • Construction of concrete-lined canals to improve the efficiency of the irrigation network.
  • To implement an economical and effective irrigation water distribution system.
  • Construction of a diversion dam across Zangebar river, 36 meters long and 3 meters from the river bed to regulate and transfer the water to the main irrigation and drainage canals.
