There are more than 30 rivers floating through my country, but the 7 more important ones are probably the Danube (Black Forest, Germany), Tisza (Rakhiv, Ukraine), Prut (Mount Hoverla, Ukraine), Mures (Carpathian Mountains, Romania), Siret (Northern Bukovina, Hungary), Arges (Mt. Fagaras, Romania) and Olt (Romania)
The Olt River- 10 Dams
Siret River- dams and artificial lakes
Mures- total of 14 dams and hydroelectric plants 
Prut- built one dam+ hydroelectric plant+ artificial lake together
Danube- one huge hydroelectric plant (broader to Serbia) and one dam
Arges- 1 hydroelectric plant


As you can see, Romania provides it's own water but I'm not sure about exporting it. 
Bucharest gets it's water from 2 other major rivers: Arges and Dambovita (like a River Sava of Bucharest) and the water is collected in 2 huge water purification centers.
