What Devlet Su İşleri Genel Müdürlüğü does

Devlet Su İşleri Genel Müdürlüğü (DSİ) is the Turkish state authority responsible for the planning, design, construction, and operation of water resources infrastructure, operating under the Ministry of Agriculture and Forestry (Tarım ve Orman Bakanlığı) and headquartered in Ankara. Established in 1953, DSİ holds a statutory mandate covering the entire water cycle — dam construction, hydroelectric power generation, irrigation networks, drinking water supply, wastewater management, land consolidation, and flood control. Its asset base includes 1,000+ dams and hydroelectric power plants nationwide, managed through specialized directorates including Dams and Hydroelectric Plants, Irrigation, Drinking Water and Wastewater, Flood Control, Geotechnical Services, Groundwater, and Renewable Energy.

The organization's service portfolio combines large-scale infrastructure delivery, real-time monitoring systems, engineering standards, and internationally-funded modernization programs. Public-facing digital products include the Baraj Doluluk Oranları (Dam Water Level Dashboard), Akım Gözlem İstasyonları (Hydrometry Observation Stations) for real-time stream flow data, the DSİ Teknik Bülteni technical bulletin, and engineering tools such as unit pricing catalogs and technical specifications. DSİ also administers professional certification programs for well drillers and equipment manufacturers and coordinates the Turkish National Hydrology Commission (TUHK). It is an active member of international bodies including ICID, ICOLD, IHA, IWRA, the World Water Council, and EMWIS, and participated in the 2023 UN Water Conference.

DSİ's revenue model is non-commercial: as a Kamu Kurumu (government state entity), it is funded by the Turkish state budget and by multilateral development bank loans. Active financing partners include the World Bank — across projects such as TIMP, TIMP2, TFDMP, TULIP, and TWCEIP — and the Asian Infrastructure Investment Bank via the TWECRP climate-resilience project. The organization employs 10,000+ staff, delivers services directly through regional directorates across Turkey, and serves as the single point of accountability for the country's hydraulic infrastructure with no private-sector substitute.

• China Water Affairs Group: Hong Kong-listed water utility providing water supply, sewage treatment, and irrigation services across China. Comparable in operating integrated urban and agricultural water services, though as a commercial entity rather than a state agency.
• Iberdrola: Global utilities operator with significant hydroelectric generation capacity. Comparable on the hydropower operations side of DSİ's portfolio, though Iberdrola is a commercial utility with diversified generation.
• Veolia Environnement: Global water and wastewater services company operating municipal, agricultural, and industrial water projects. Comparable in water supply and wastewater operations, though Veolia is a commercial operator rather than a state infrastructure owner.
• Suez Environnement: French-based global water and waste management firm with significant water utility operations. Comparable on water supply, wastewater treatment, and resource management services; serves as a private-sector counterpoint to DSİ's state-led model.
• Companhia de Saneamento Básico do Estado de São Paulo (Sabesp): Brazilian state water utility providing water and wastewater services at scale. Comparable in serving large populations with integrated water supply and sanitation, though focused on urban distribution rather than dam construction.
• Environment Agency (UK): UK public body with statutory responsibility for flood risk management, water resources, and environmental regulation. Comparable in flood control and water resource stewardship mandates, though operating in a regulatory rather than infrastructure-owner role.

Regional players

• Water NSW: Australian state-owned water corporation operating dams, weirs, and bulk water supply infrastructure. Comparable as a state-owned integrated water resources manager with dam operations and hydrological monitoring, though geographically focused on New South Wales.
• Federal Waterways Engineering and Research Institute (BAW, Germany): German federal institute providing engineering expertise for inland waterways, hydraulic structures, and water resource management. Comparable as a government-affiliated technical authority in hydraulic engineering, with a consulting/scientific mandate rather than direct service delivery.
