The capital city is fortunate enough to be supplied with plentiful high-quality groundwater. In water protection areas, around 650 wells bring ground water to the surface, which is then piped to the waterworks. There, the proportion of iron and manganese is reduced through aeration and filtering. The clear and fresh water, free of additives and at a temperature of around 11 degrees centigrade, flows into the supply network. Its quality is closely monitored around the clock.
Thanks to its high content of magnesium and calcium, Berlin drinking water is very healthy.
