HISTORY OF IV th REGIONAL DIRECTORATE

IV th Regional Directorate of State Hydraulic Works was established in March 1 st, 1954. Konya, Niğde, Antalya, Afyon, Isparta and Burdur, which are provinces of Turkey, were in responsibility area of our Regional Directorate in early years. Antalya XIII rd and Isparta XVIII th Regional Directories were established in 1960 and 1968, respectively. Therefore, IV th Regional Directorate had been become responsible only for Konya and Niğde after 1968. Aksaray and Karaman that are county of Niğde and Konya respectively had been transformed into provinces in 1989. Thus, numbers of provinces in responsibility area were increased in our Regional Directorate.
