The headworks and powerhouses of Bakhvi 1, Bakhvi 2A, and Bakhvi 2B HPPs are interconnected through a high-pressure pipeline system.
- Bakhvi 1: Pipeline length – 3,815 meters; internal diameter – 1,100 to 1,300 mm.
- Bakhvi 2a: Pipeline length – 3,283 meters; internal diameter – 1,200 to 1,400 mm.
- Bakhvi 2b: Pipeline length – 3,753 meters; internal diameter – 1,300 to 1,500 mm.
Bakhvi HPP has partnered with Turkish pipe manufacturing company NOKSEL for the supply of the pipelines. The steel grade used for the pipes installed in the Bakhvistskali River Valley is 355J2 and X-65.
To minimize erosion, visual impact, and for site reclamation purposes, the Bakhvi 2b low-pressure pipeline section has been seeded with grass. Additionally, the company will employ a hydroseeding machine, which enables seeding even in hard-to-reach areas.
