In 2007, freshwater abstraction was 6.2 billion.m3, which is close to the average volume for the last eight years (6.3 billion m3). The highest level was registered in 2003 (7.3 billion m 3) and the lowest was in 2005 (6.0 billion.m3). Fluctuations in water volume is determined mainly by water power station. Groundwater constitutes 8 % of total water abstraction and this water abstraction is mainly for drinking purposes. In 2007, underground sources were 473 million m3, which constitute 82 % of those in 2000. One of the main reasons for the decline in water abstraction is the increase in the costs of abstraction and delivery service. Approximately 67 % of fresh water in 2007 were abstracted by own supply business unit and the remainder is divided between providers - public water supply (water companies) and irrigation systems.
The pressure on water is assessed by the ratio: freshwater abstraction/available freshwater resources. Warning threshold is set around 20%, while consumption of more than 40 % indicates an unsustainable water use. Abstraction in the country after 1992 fall into the frameworks of sustainable development.
