Project is located around Çukurçayır village of Araklı district within Trabzon city which is inside Eastern Black Sea Basin.
Five diversion weirs with capacities ranging from 200 lt/sn to 1000 lt/sn were designed and constructed. Weirs are located at upland of Blacksea region where M.S.L is over 1800.0 m. During winter and late autumn access to weir locations is impossible. Therefore each weir was equipped with special design Coanda screens with 1.0 mm openings which are resistant against freezing under severe winter conditions. There exist no settling basins for each weir.
Headponds are designed underground and are also storage ponds for regulation of energy during peak hours. The 600 mm diameter penstocks are also buried.
There exist two horizontal two jet Pelton turbines manufactured by Koessler inside power house. Each unit has same design discharge but has different net head and installed power of each unit is 1.89 and 2.92 MW. All the major components of the project were designed underground and the main aim of the design was to minimize destruction of natural scene.
Araklı-1.1 project is a good sample for an economical small hydro power design where lots of small creeks are the main water resource.
