The Project provides for the construction of new gravity irrigation system that is a buried pipeline of 4887m length and is made of pipes of 820×7 mm in diameter, and the headworks of which coincides with the headworks of the open Nalband canal. The intake of water is made from the Chichkhan River. The pipeline is connected with the existing siphon with 1200 mm in diameter. The isolation of the inner and external surfaces of the pipes was implemented.
Nalband pump station was abolished by the construction of the pipeline.
This system will provide 545 l/sec discharge of water for irrigation of 800 ha land in Shirakamut, Metz Parni, Saralandzh and Katnajur Communities. The works include the excavation of soil and trenching both in the terrain and along the riverbed, placing of conduit pipeline with waterproofing, construction of the headwork structure, particularly of concrete, steel structures, water outlets and gauging stations, construction of distributing and emptying reservoirs, required metal working processes, mounting of gates, transportation and installation of materials at the construction site.

The following scope of work was implemented:
