DSI - General Directorate of State Hydraulic Works

What DSI - General Directorate of State Hydraulic Works does

DSI (Devlet Su İşleri Genel Müdürlüğü) is the General Directorate of State Hydraulic Works, the sole Turkish state authority mandated to plan, construct, and operate the country's hydraulic infrastructure. Operating under the Ministry of Agriculture and Forestry and headquartered in Çankaya, Ankara, DSI employs 2,346 staff and administers 26 regional directorates covering all Turkish provinces plus a dedicated KKTC Project Directorate for Northern Cyprus. Its mandate spans dams and hydroelectric power plants, irrigation and drainage systems, drinking water supply, wastewater infrastructure, flood control, hydrometric monitoring, land consolidation, and renewable energy development.

The organization's technical backbone includes accredited technical research and quality control laboratories, hydrometric observation stations, equipment-manufacturer compliance evaluation, and the Turkish National Hydrology Commission (TUHUK). DSI issues authoritative sector references including DSI Unit Prices and General Technical Specifications used across Turkish hydraulic engineering. Its digital surface comprises the SUTEM Irrigation Technologies Center, Decision Support Systems for irrigation management, and a real-time web-based Dam Fill Rate Monitoring service. DSI holds ISO 27001 (2025) and ISO 9001 certifications and participates in ICID, ICOLD, IHA, IWRA, the World Water Council, and EMWIS.

DSI is funded by the Turkish national budget and multilateral development loans rather than commercial revenue. It serves as the implementing agency for World Bank programs (Turkey Water Cycle and Efficiency Improvement Project/TWCEIP, Turkey Irrigation Modernization Project/TIMP, Turkey Flood and Drought Management Project/TFDMP, Turkey Resilient Landscape Integration Project/TULIP, and Turkey Second Irrigation Modernization and Water Efficiency Project/TIMP2) and the Asian Infrastructure Investment Bank's Turkey Outcome-focused Water Efficiency and Climate Resilience Project (TWECRP). Operations are delivered through government-to-government procurement, public tenders, and partnerships with irrigation unions and agricultural cooperatives; no commercial pricing model applies.
