Total water consumption from industry dropped from 2004 to 2008. The major ground water users are water supply (21 per cent), industry (14 per cent), observation (14 per cent), agriculture (6 per cent), thermomineral (3 per cent), and 42 per cent not classified. Access to regular clean and safe drinking water is an essential part of public health (see Chapter 10). The percentage of connections to public water supply systems in the municipalities-urban areas is much higher than the average and higher compared to rural areas.
