Irrigation and Small Dams
For the State Hydraulic Works (DSİ) we build pressurised piped irrigation networks, small-dam embankments and their appurtenant structures.
Our work for DSİ began in 2001 with the Yamaçoba Small Dam and Irrigation project in Gaziantep and continued with irrigation projects in Şanlıurfa, Afyonkarahisar, Ankara and Isparta. On these projects we built conveyance lines, main and lateral pipelines, energy-dissipating valve sets, hydrant and air valve structures, drainage channels, and stream and road crossings by horizontal drilling.
Work is currently in progress on the 24,500-hectare Dalaman Plain Irrigation project in Muğla, the Apa Hotamış irrigation schemes in Konya and the 7,100-hectare Sadak Dam Irrigation project.
Scope of work
- High- and medium-pressure piped irrigation networks (steel, GRP, PE100/HDPE)
- Small-dam embankment fill, spillways and bottom outlets
- Water intakes and pumping stations
- Filter stations and energy-dissipating valve chambers
- Hydrant, air valve, division and washout structures
- Stream and road crossings by horizontal drilling
