Benefit: Use of raw water

The communal water supply has been approximately 410 million cubic metres annually in recent years. About 90% of the population is inside the distribution network and 10% is dependent on their own water sources, most commonly private wells. Over half (61%) of the communal water supply originates from groundwater deposits and the rest (39%) is processed from the surface waters.
