Freshwater - Drivers and pressures (Slovakia)
Socioeconomic development and climate change generate pressures causing negative effects on water quality and quantity in Slovakia. The main impact causes are agriculture, industry and urban activities.
In 2009, customers used approximately 14 % of the documented usable groundwater volume. Nearly 75 % of groundwater abstractions were used for public water supply purposes. Since 1990, groundwater abstractions have had a decreasing tendency (see Figure 2). Similarly, surface water abstraction has had a decreasing tendency (see Figure 3). In 2009, total extracted volume of surface water was 279 million m3. More than 80 % of surface water abstractions were for industrial purposes.
From 1998 to 2009, the volume of discharged wastewater decreased by 54.4 % in Slovakia. In 2009, the total volume of discharged wastewater into watercourses was 620 358 090 m3. The percentage of discharged treated wastewater of the total volume of waste water discharged into watercourses in 2009 was 94.67 %.
Sewerage system and public water supply
In 2009, 3 225 000 inhabitants were connected to the public sewerage system, which represents 59.4 % of the population (see Figure 5). The development of public sewerage systems significantly lags behind the development of public water supplies. In 2009, the number of inhabitants supplied with drinking water from the public water supply reached 4 682 000 which represents 86.3 % of the population (see Figure 4).
