The Sorkheh Hesar project is a critical urban infrastructure initiative focused on underground utility installation—such as water, sewage, or service conduits—in eastern Tehran. Unlike traffic tunnels, this tunnel is designed exclusively for pipe-laying operations, contributing to the modernization of the city’s underground networks.
Khara Dezh led the full scope of the project—from design to execution and supervision. Leveraging modern tools, technical expertise, and integrated engineering management, the company delivered a reliable, safe, and technically sound infrastructure solution.
Every phase of the project was executed under strict safety protocols and quality control. Continuous ground monitoring, use of durable materials, and precision engineering ensured minimal risk and maximum durability throughout the pipe-laying process.
Approximate tunnel length: 2,200 meters Open trench channel length: 55 meters Pipe-laying operations: 300 meters via microtunneling 110 meters via open trench method These dimensions reflect the scale and complexity of the project, requiring precise planning, advanced equipment, and expert execution.
