Sattarkhan (Ahar) Clay Core Earth Dam & Related Facilities
Client: East Azerbaijan Regional Water Authority
Consultant: Bandab
Type of contract: C (Construction)
Location: Ahar, East Azerbaijan province, Iran
Status: Completed
Project Overview
Over the past decade, our country has made substantial investments in the development of water infrastructure and the optimal utilization of limited water resources. This has consequently generated extensive and growing opportunities for companies possessing the necessary capabilities to deliver high-quality services in this sector. Aligned with its strategic decision to diversify its activities and engage more actively in crucial projects, Kayson is endeavoring to play a more significant role in the development of the country’s water infrastructure. This is achieved by leveraging its technical-engineering, managerial, human, and other resources.
Sattarkhan Earthen Dam, constructed by Kayson Company on the Ahar River in East Azerbaijan Province, aims to achieve three primary objectives:
- Controlling the river’s frequent flooding
- Supplying drinking water to the region’s residents
- Providing agricultural water for 12,000 hectares of farmland land
Sattarkhan Reservoir Dam, boasting a volume of 131 million cubic meters, is an earthen dam featuring an impermeable clay core. It stands 75 meters above the bedrock and has a crest 350 meters long. The dam’s catchment area spans approximately 950 square kilometers. To facilitate river diversion during its construction, a tunnel with a diameter of 5.5 meters, a length of 438 meters, and a longitudinal slope of 0.8 to 1 percent was built on the dam’s right side. Upon the dam’s completion, this diversion tunnel will be repurposed as a water intake and for lower discharge. The capacity of the lower discharge tunnel is impressive, capable of emptying the reservoir in just 24 days with the aid of the water intake. Furthermore, the dam’s water intake system is designed to supply 7.8 cubic meters per second of water for agricultural use and one cubic meter per second for urban consumption.
