Poldasht Irrigation & Drainage Network

Project Overview

Poldasht Irrigation Project is located in West Azerbaijan Province, approximately 25 kilometers from Poldasht city. Its operational area was bordered by Marand transit road to the west, Poldasht-Maku road to the north, and Poldasht city and Aras River to the south and east. The project involved execution of modern irrigation and drainage systems across five development units, covering 12,000 hectares of agricultural land. Unit number one, spanning approximately 3,700 hectares, was assigned to Kayson Company. A key feature of the project was the construction of a diversion dam, which served as a central site. Additionally, 16 main and secondary canal branches and drainage systems were built, along with all associated structures, within a triangular area whose sides averaged about 20 kilometers in length.

The main objectives of Poldasht project were:

Discharging wastewater and draining land by gravity into the river

Constructing concrete-lined canals to enhance irrigation efficiency

Ensuring economical and reliable water distribution through the execution of a proper water distribution system
